Ok, Matt- please put the template at the top of this page (the discussion page) as that has become the norm. I think you should be the nominating editor. The date should be at least a week so that we can continue to hash things out, please. Also- shouldn't this be healing arts workgroup? Is it so designated?

Hi Matt, well done. I've done a first run copy edit, culled out some bits that seemed to me to be rather introspective argument, and tried to put in a couple of bits based in part on the comments in the Talk page on WP. I'll come back to this, but I've bust my specs so ...Gareth Leng 07:23, 12 January 2007 (CST)
- No problem! You probably needed a break:) It is really neat to watch things transform and "mature" as you make your changes. Like always, you've kept the concept and said it better. I am curious about the science section (more as a student:), did I misinterpret it, or did you think it wasn't necessary? --Matt Innis (Talk) 07:35, 12 January 2007 (CST)
No, no misinterpretations. I guess I saw the general case as mainstream established science, not new or controversial, and I thought that presenting it there made it seem new or controversial, especially by picking a few primary studies rather than quoting reviews. I'll come back to this though, and think again.Gareth Leng 09:58, 12 January 2007 (CST)
- Okay, as long as I didn't read it wrong. After listening to critiques for so long, I begin to doubt myself sometimes;) Just wanted to make sure I was interpreting the information the way it was presented. If you don't think it is necessary from an editorial POV, I'm okay with that. I could go on for hours, but surely don't want to bore the audience:) --Matt Innis (Talk) 12:18, 12 January 2007 (CST)
- I added some in the intro as well. Feel free to work with it. --Matt Innis (Talk) 15:59, 12 January 2007 (CST)
Matt, here's the problem I have with this article, its the same problem I have with vertebral subluxations- I can't grasp it because it always seems to be presented with circular reasoning. Here's what I mean: as far as I can tell a vertebral subluxation is something that must exist because fixing it cures a problem. But- there does not seem to be anything concrete presented about how to objectively tell a vertebral subluxation is there, The "scientific proof" does not address identifying a vertebral subluxation, in other words- granted that a misalignment of a vertebral joint can lead to arthritis, but vertebral subluxations are treated by chiropractors all the time when there is no measureable misalignment of the joint. I'm not saying that your working on the back is not effective, I'm saying that the theoretical basis may be imaginary. I was bringing this up in the Chiropracter article, believe me in medicine many physicians avoid having their examining skills tested, but some don't. In those who don't, if there is a diagnosis that is made on clinical examination the exams of many physicians can be compared. This is a lot of work, but not expensive and so, I don't buy that chiropracters don't have the support of major grant makers and that explains the lack of these kinds of studies. Maybe they do exist and you and I are not aware of them. Bottom line- what's the evidence that one chiropractor finds the same problems in a back that the next one does? It doesn't make sense to me that we say vertebral subluxations exist because of history and Palmer. Nancy Sculerati MD 18:45, 12 January 2007 (CST)
- Okay, so what you are saying is that you would like to see some sort of solid information on how a subluxation is found and maybe some proof that there is some degree of certainty that several blinded doctors would find the same thing. I think there were some tests done in the 80's on this very thing. I'll see what I can find. --Matt Innis (Talk) 23:28, 12 January 2007 (CST)

Are physicians leery of the claims made by chiropractors? What about Osteopathic Docs and Physical Therapists? I know that in terms of osteopathic manipulation, I trust the DOs coming out of the number 4 school in the nation for primary care - MSU COM, and one really good physical therapist who works in Okemos, MI. However, I definitely benefit from having T3-T5 joints "loosened up" about once a week - but I can do this sitting in a chair and pushing inferiorly and stretching my spine that way - pop, pop, pop. I'm interesting in reading more, even though I'm biased. I'm also really interesting to read some of the really new and interesting physical therapy research that is starting to get published. -Tom Kelly (Talk) 20:16, 12 January 2007 (CST)
- Hey Tom! Yes, I think it is safe to say that we are all leery of each other;) I don't blame you for being biased, DCs don't have the best reputation - mostly because we have some that keep shooting us in the foot:) Feel free to add whatever you like, and certainly at least check my spelling! I'm thinking "subluxation" in the upper thoracic region;)lol. --Matt Innis (Talk) 23:28, 12 January 2007 (CST)
- I'd be wary of having this article become a representation over the debate about whether subluxations are real or not because its clear that as the term is used with such different intents even within chiropractic it is going to get confusing and will go nowhere. Nancy's difficulty seems to me to be that she's understood it exactly, yes, for some chiropractors, subluxation is simply whatever explains why chiropractic works - i.e. for them its an empirically evolved treatment with a rationale (subluxation) that seems to them to be a useful explanation of why it works, not least because patients can understand and be reassured by this. So I think the article should describe how the term is used 9in its various ways paerhaps) rather than try to make a consistent "scientific" definition of something that is not always used as such..???? Matt?????...Gareth Leng 05:53, 13 January 2007 (CST)
- Good point. I think your consolidation on the science section does sum up the science pretty well, which is probably close to all we should try to do, because otherwise we open the door to a boatload of back and forth science that only adds volume but not content. Hopefully those that are interested can read the references - and we can add some there as we find them. We will end up with the same "feeling" that you have summarized already: that the "proof" is lacking - which doesn't bother most chiropractors because if they are science oriented, they are using subluxation in the somatic sense anyway and only use the visceral sense as a "lets watch and see" attitude. If they are "subluxation" based then they probably feel like BJ and think that if it is ever proven, medicine will steal it. Keep in mind that physical therapeutics was pioneered by chiropractors and a lot of the "really new and exciting stuff" has been around for awhile in chiropractors offices. A lot of what is now conventional thought has it's roots in chiropractic. Just as DOs have been drawn toward allopathy, PT has inevitably been drawn toward chiropractic. The fear was that if they prove it, scientific medicine will steal it and call it their own and chiropractors will have nothing to practice - after all they could not practice in hospitals or use any of the equipment until after 1991 - that was only 15 years ago. Along that same line, I think Nancy's POV is one that a lot of people have about chiropractic (including some chiropractors) that we need to handle - at least the subluxation part on this page. In the early 80's, chiropractors made an attempt to clarify what a subluxation was and went from subluxation to vertebral subluxation complex. I can at least put some of that in and then we can see if it makes more sense. I am glad for the discourse because this is where I get bogged down trying to decide what needs to go into the 32Kb article;) I need both your POVs. Thanks. --Matt Innis (Talk) 08:54, 13 January 2007 (CST)
- Well, the PT research I was referring too mainly deals with peripheral nerves and the neuromuscular repair process, but I'm sure there are always great clinicians who have "theories" long before any research is ever done to prove it. And we all know that the world is driven by money. Just like there isn't as much money funding cranberry research as there is in other Drug related fields, there is less money in chiropractic research as in other fields. "Stealing?" How is that really possible if one person gets it published in a journal before "medicine steals it?" -Tom Kelly (Talk) 14:11, 13 January 2007 (CST)
- Good comment, Tom. It is a really interesting story with lots of personalities and drama. If your interested, check out Chiropractic History, it will give you a better feel for how chiropractors think and why they think that way. "Steal" might not be the right word, but you'll see what I mean. --Matt Innis (Talk) 11:01, 15 January 2007 (CST)

Hi Matt, I looked at the JVSR site and saw that they dad some thumbnails of covers from Historic Print Editions _ wondered if one of these might be appropriate? On the science side, think it's important to stay quite light. There is no doubt that the spinal nerves do a lot more than just control muscles, so the idea that nerve dysfunction might have wide consequences is certainly credible, but on the other hand giving this too much weight may tend to make it appear that the subluxation theories are accepted, and that,s also not true - my reading is that they are credible explanations for things that we don't understand, but they might be wrong - we just don't know enough to be sure. As a wholly personal and unexpert bias I'd say that I think its very likely that spinal dysfunction in some cases does cause some of the "unexplained" symptoms in peripheral organs, but whether this is common or uncommon I'm not remotely qualified to judge. So I feel the right path is to acknowledge the credibility of the explanations without seeking to imply that they are necessarily true explanationsGareth Leng 10:25, 13 January 2007 (CST)
Okay, I think I'll just try and handle Nancy's concern without making judgements either way. I can't find the pictures your talking about. Can you point me in the right direction? --Matt Innis (Talk) 12:14, 15 January 2007 (CST)
The covers are on the website - unfortunately the downloadable ones have draft written all over them, but I was thinking that this cover might be good as a thumbnail, if it's possible to get a clean image? [1]Gareth Leng 04:47, 16 January 2007 (CST)
- Were you thinking the whole cover (including the journal name) or just the picture of the spine? I assume you want me to try and get the "draft" off of it? What size do you want it to be - small like 1" or more like the gymnast picture of 4"? --Matt Innis (Talk) 10:19, 16 January 2007 (CST)
No I thought it might be possible to show a thumbnail of the cover, down at the bottom of the page. I have to admit when I went into the website page first the thumnnails were there but blocked and I assumed it was just my overprotective firewall, I later realised that I could access the covers but only with DRAFT all over them. Thought that a thumbnail of a journal cover would be fair use and easy to get - didn't mean to engage you in any hassle (dooh) Gareth Leng 11:50, 16 January 2007 (CST)
- No problem! I can dooh that:) I'll put it here on the talk page and you can find the spot you want it. --Matt Innis (Talk) 13:25, 16 January 2007 (CST)

I can make it bigger without too much a dooh about nothin'.
I guess it has to be readable. What you think? This was just an idea, might have been a bad one. One of the problems is that red on black is not very readable at the best of times....Gareth Leng 04:17, 17 January 2007 (CST)
Flesnia....hmmmm...think I know what this stuff means, but there's a mish mash of jargon and hype here. It reads a bit like scare mongering in places and needs care and caution I think :)Gareth Leng 05:07, 17 January 2007 (CST)
OK. I'm not sure that I "get" this.
I think this is about the motor programmes that are learned in the spinal cord and in the cerebellum and brainstem. This motor learning occurs when networks of neurones are trained to behave in a new way. Actually we know quite a lot about this, but basically it involves strengthening connections between some neurons and weakening other connections, and this depends on "feedback". This type of learning is happening everuwhere in our nervous system all the time. In this case, if an injury forces some restriction of movement, initially the person may consciously move in a way that avoids pain, using a strange or unfamiliar sequence of muscle commands. Initially these movements will be planned and directed by higher centres of the brain, but with repetition, lower centres learn these sequences and take over, and the new set of movements then becomes instinctive.
Now this happens all the time and there's nothing irreversible or pathological about any of this. I think the suggestion here is that a subluxation means that the feedback information needed to train these networks is wrong, and so the new programmes that are formed are not optimal adaptations?? Gareth Leng 05:36, 17 January 2007 (CST)
Yes, it does happen all the time. And yes, I think you have the concept. Also note that even if the feedback information was correct initially, damage to the facet capsule results in fixations and that results in adaptations that result in changes in load bearing on the facet joints that are forced to adapt. The information coming from the facet capsules - which are loaded with mechanoreceptors and nociceptors - is either fascilitated or inhibited, either one having an altering effect on the rest of the system... One of the ways of detecting is because heat can be detected (Neurocalimeter, thermography, palpation) and it will be tender to the touch (palpation, patient feels it, sympathetic nervous system facilitated pain). Make sense? --Matt Innis (Talk) 10:29, 17 January 2007 (CST)
- More -
- nothing irreversible - so long as the abnormal joint function/fixation is removed. If it remains, the process cannot reverse to "normal", right? It may adapt to something that is fine, but it is never optimal again.
- nothing pathological - not as far as being a normal response by the nervous system - but, the degenerative effects of fixating the joint develop into osteoarthritis - won't kill you but can make life less enjoyable by itself - add to that:
- facilitated and/or inhibited autonomic nervous system as a result of the overactive or underactive feedback from mechanoreceptors and nociceptors within the joint capsules of these osteoarthritic joints (and, yes, even in the beginning stages when there are no visible changes on xray). Does this affect the end organ (the organ that receives its innervation from the same spinal segment)? DCs think yes, perhaps via lamina I and IV where the "spillover" of neurotransmitters affects the facilitation of or inhibition of the sympathetic ns that have some effect on the "end organ" per a mechanism such as we describe in the next section. We don't know, yet.
- Helpful? --Matt Innis (Talk) 11:49, 17 January 2007 (CST)
OK, I'll have a go - I have some problems with the way it's written, so will edit out somephrases or words the meaning of which isn't clear to me or seems wrong, just scream if I take out something importamnt and we'll try to work it out. First problem is in knowing exactly what is meant by homeostasis here. Is this just a loose buzzword or is something very specific meant? But maybe you'd like to go at it first because I think you'll write it a lot better than Flesia did.Gareth Leng 11:46, 17 January 2007 (CST)
Organizational changes made- need more on DC research
Matt and Gareth (and others who may be out there!) I have made some organizational and language changes that I believe clarify the article. Please read through from the beginning. Matt, I think presenting the uncontested view of the spine etc, meaning that which DC and health science agree on, followed by the DC focus is a good and clear method of explanation. You had sent me refernces on actual DC research and this is what needs, in my mind, expansion. I'll wrtite you also on your talk page, regards, Nancy Sculerati MD 11:58, 17 January 2007 (CST)
- Thank you, thank you, thank you.. I do apprectiate your help. As a side note to your sectioning of the article into health science and chiropractic, I think if you really examine the thoughts and theories you are going to find that 99% of chiropractic belongs in the health science section. Maybe 1% voodoo. That won't leave much for the VS. But then again, maybe it is time we acknowledged that we aren't that far apart. --Matt Innis (Talk) 12:14, 17 January 2007 (CST)
No objective evidence
Nancy, I notice that you concentrate on the "no objective evidence". I'm not sure if we have different concepts of "objective" evidence. IOWs, is palpation objective? When you palpate a lymph node, do you guys consider that objective evidence or is it only hard copy things such as blood tests, xrays, and MRIs? Really the only thing that we consider subjective are the things that patients tell us. We consider palpation and range of motion as objective evidence. Is that the way it is in medicine? IF it is, maybe we could clariy that some so it doesn't sound like DCs are just flying from the seat of their pants. --Matt Innis (Talk) 12:03, 17 January 2007 (CST)
- I've palpated "a stiff back" before and after a PT has "loosened up" some joints. I'm not saying that was the right thing to do in all situations (and for many other reasons, cracking of backs is done too much, too often, and may have false claims in many situations), but i have seen it done in situations where there is immediate improvement. However, most people crack their back when all they really need to do is fire a few intervertebral muscles (and others) in a certain way (resistance, etc) to solve the underlying problem to their back pain without cracking the back at all. My bias against cp is often that they will align your spine but not deal with the muscles and underlying issue that caused the problem in the first place. I see where things can be argued both ways and where things are overused. However, it is possible to palpate stiff back joints, and I'm only a medical student. I don't actually time to read the article to even figure out what you are claiming to palpate, but i know in certain situations you can palpate joints that aren't moving like they should. And isn't it true that if you try to "crack" joints that are moving fine, they don't "crack" as often? -Tom Kelly (Talk) 16:11, 17 January 2007 (CST)
- You certainly bring up some interesting "chicken or the egg" points;) Which came first, the muscle problem or the joint problem - and does it matter? Another good research project! However, as to the "'cracking' joints that are moving fine, they don't 'crack' as often", we pretty much know that it's just the opposite. IOWs, it's a combination of the tight muscles, shortened joint capsules and ligaments that won't let the joint seperate enough to create the vacuum necessary for cavitation(check out Chiropractic) to occur. The stuck one is one type of VSC. That is the one that needs manipulation type adjusting. There is no benefit in creating too much motion in a joint that is functioning normally already, which is what is happening when you are hearing those "cracks" on yourself. You're moving the ones that don't need moving. It feels good because you are firing the mechanoreceptors - like scratching an itch, you get some temporary relief, but you haven't really changed anything. As far as using muscle stretching, etc. consider this - if a facet joint is fixated from an injury and there are 10 other facet joints around it that move just fine, how are you going to create motion in the one stuck joint without creating more motion in the normal ones? Manipulation is used to move the "stuck" joint without creating more motion in the ones that aren't "stuck". It's purpose is to force that facet capsule and surrounding ligaments to lengthen, thus allowing more motion in the motor unit. So stop "cracking" those thoracic vertebrae:) --Matt Innis (Talk) 20:40, 17 January 2007 (CST)
- How do you create a motion that fixes the problem? have a D.O. who is really good at osteomanipulation fix the problem! (just a little bit of a friendly jab!) I wish they taught 4 years of osteomanipulation at MD school like at DO. Oh well. -Tom Kelly (Talk) 21:31, 17 January 2007 (CST)

A lymph node is objectively palpable, and yet can be missed by some examiners, absolutely if you operate, you find it. It is my understanding that a vertebral subluxation may exist even without externally verifiable objective evidence. Meaning: a DC feels its there but there is no "gold standard" in objective evidence to verify it. I look through the refernces, and I may not have interpreted them correctly, but I could not find any thing. Can you? If you object to the language changes I made, please alter them and we can go back and forth until we are both satisfied.Nancy Sculerati MD 12:48, 17 January 2007 (CST)
- Sounds good. If you look at the references, they talk about palpation with provocative testing being intraexaminer and interexaminer reliable. Basically what they are saying to me is that when an examiner is able to palpate and put that together with range of motion and other tests that create pain, the results are reliable with other blind folks. They also state that when used by itself, palpation is not acceptable. I know in my office, I use palpation where I may find "lumps and bumps", but I'm not convinced that these are adjustable lesions until there is an element of pain elicited, whether with palpation or with range of motion or orthopedic testing (suggesting to me that the sympathetic ns is facilitated at that level). Do note - however - that a lot of the times no pain noted by the patient until it is palpated. In other words, it's like a carie on a tooth, you don't know it is there until the dentist pokes his little probe into it. As a disclaimer, that does not mean there aren't DCs out there doing some weird stuff, but I think most of us would find similar findings - and so would you if you were taught what to look for. The only thing we do that you don't is that we might add to our list of "positive" findings for a subluxation in the midthoracic region is that subjective complaint of indigestion that they have been suffering with for three years. We then treat the subluxation and "wait and see" what happens to the indigestion, because we are just as unsure as you are that it will help, but we also don't know that it won't, yet. Am I making sense? --Matt Innis (Talk) 13:27, 17 January 2007 (CST)
Yes. I did read, I think in one of the Gale reviews, that pain was an inter-observer finding that was statistically significant. This is just what we need to go over in detail, and would be a real contribution to have - in my mind, anyway, as much on this as we can. But we have to go through those papers line by line, and not skim them, and discuss them line by line, and pull Gareth and others into the discussion in a no-holds barred, no bullsh*t effort to come to an understanding. When I use that rough and tough language, I do not mean it with animosity, I mean that we do respect each other and we are friends - but we are not going to lie to each other to "make nice", instead we are actually going to try to figure out the limits of what we think and believe about the subject, and what we can say here as truth. Frankly, there is grant support available from NIH for doing good studies on alternative medicine and the right design to test some of these points could even be come up with by us! Back to your original objection - my point about objective evidence is that is is not required for the diagnosis of a vertebral subluxation, and clearly- unless I have totally misunderstood (and yes, that does happen!) vertebral subluxation is not a concretely understood entity among DCs. If I am wrong about this point, please do not be too polite to openly correct me. So, my understanding is that its not like a lymph node in that sense, as you say- some even deny it exists whereas although MDs might disagree abouth whether they feel an enlarged node on a particluar exam, no one says they question the existence of lymph nodes. There are other equally real findings on a clinical exam, a heart murmur, a middle ear effussion, that are not obvious to all examiners- but again there is always some technical way to check the exam. It seems that there is no one specific agreed upon concrete finding for vertebral subluxation, but there is a common method among DCs for examining the back and there are shared methods among DCs for treating what they find, and that's where I think it makes sense to focus the rest of our efforts in this article. When it comes to "the science", it's kind of silly to try to review the zillions of bytes of knowledge about the anatomy and physiology of the spine from a general perspective, on the other hand, I (at least) have never come across an article written for the lay public that really tried to explain a chiropracter's thinking and really reviewed the techniques and the scientific evidence in a detailed way. I think that putting vertebral subluxation in that context is an exciting challenge. Nancy Sculerati MD 14:09, 17 January 2007 (CST) P.S. Tom, from what I have gathered through my reading and writing the Chiropractic article, there are identifiable changes in the exam that might correspond to subluxations, but these are very subjective to the examiner. Even babies get their spines adjusted, and it's not as if a DC vertebral subluxation corresponds to a well-defined anatomic abnormality, but that is not to say that the concept is fallacious, it's just to say that it is (in my mind, anyway) speculative. Matt, in medicine the difference between pain with palpation and pain even without being touched is that the first is called tenderness, and it is a distinction that does give information. Obviously, sometimes there is pain both ways as well, usually getting worse with palpation, but there are some pains that are somewhat relieved with pressure too, often depending on how the pressure is applied.

- Nancy, you keep saying things like this: but these are very subjective to the examiner and it's not as if a DC vertebral subluxation corresponds to a well-defined anatomic abnormality. Exactly what is it that is not objective about what you have seen? I'm puzzled. --Matt Innis (Talk) 21:00, 17 January 2007 (CST)
- Pain is similar for us, though we would use pain to describe all different types of sensations, including parasthesias. When we talk about provocative testing, we look for motions or positions or procedures that provoke the symptom. I'm sure that's the same for you. So palpation with provocative testing is reliable intra and interexaminer. --Matt Innis (Talk) 21:06, 17 January 2007 (CST) P.S. We also consider that as an objective finding - you would, too, I assume. --Matt Innis (Talk) 21:08, 17 January 2007 (CST)
Well, sorry to butt in here. Pain is classically a very difficult issue, and it's just not possible to quantify how much pain is felt by an individual, or to know whether the experiences of any two people are similar even when they describe it in similar terms. Accordingly we don't regard assessment of pain as objective - this does not mean it's not real or not important. The problem is that in coming to a diagnosis, pain may a) be reported differently by different people even if the cause is identical, b) be reported differently by the patient depending on who asks the questions or how or in what circumstances they are asked, and c) perception of pain may arise in many different ways and be blocked out in many different ways. So while minimising perception of pain is clearly a major objective of treatment, the subjective nature poses real difficulties for diagnosis. I think part of the difference in perspective may be related to the fact that in conventional medicine patients are typically seen by a succession of different specialists, whereas patients of chiropractors are under the continuous care of a single individual. So inter-observer differences in how symptoms are measured and recorded are much more problematic in a conventional setting, hence the emphasis on objectively documented findings. ???? Gareth Leng 04:15, 18 January 2007 (CST)
- I agree with everything said with regard to the sensation of pain - it can be different from patient to patient, but provocation of pain is the key feature here. IOWs, if I find a "spot" that I think is suspicious, I then stand the patient up and put them through flexion, extension, laterally flex them, raise their leg to stretch it, etc. When the patient identifies that as painful(regardless of their perception of what pain is), the reliability from examiner to examiner and for me to find the same spot again is good. Also, in subsequent evaluations, a decrease in that sensation of that same pain by that particular patient when scored using scales such as 1 to 10 are found to be also objective. I think that is what the research is saying. You? --Matt Innis (Talk) 08:03, 18 January 2007 (CST)
Matt, please don't be offended. Please put the language of the article in a way that reads correctly to you, you may change any of the words I placed and - although I might make more changes-I won't "squawk". :) Nancy Sculerati MD 08:34, 18 January 2007 (CST)
- No problem, I have to work in spurts and need to wait till I have a good block of time. Besides, I have to go get my boxing gloves out of the recycle bin. --Matt Innis (Talk) 08:53, 18 January 2007 (CST)
Wording
I really don't think we're far apart, it's just that we're reading different things into the words. Can we take the sections that might need agreement? Maybe this is the first
"Although this definition uses the phrase "neural integrity", that term is used strictly within the framework of chiropractic, and does not imply that any objective measureable electrophysiological inhibition of nerve impulses, or measureable anatomic misalignment of the joint on x-ray or by other imaging study, is required for a chiropractic diagnosis of vertebral subluxation."
OK, how about this instead?
"Although this definition uses the phrase "neural integrity", this is a chiropractic interpretation of the condition; diagnosis of vertebral subluxation does not involve any direct evidence of electrophysiological inhibition of nerve impulses, nor does it necessarily involve any direct evidence of anatomical misalignment of the joint on X-ray or by other imaging study."
Perhaps direct evidence is better than objective evidence, and I think that's what we might really mean - :)Gareth Leng 10:26, 18 January 2007 (CST)
- I think it needs more than that. This is a definition worked out by likely literally hundreds of scholarly minds with expert knowledge of the profession. I think they meant neural integrity in the english language sense of the word when they said neural intergity. It's kinda weasely to say, "yeah, but your neural integrity is different than my neural integrity." It makes it look argumentative and POV. Don't you think? --Matt Innis (Talk) 11:16, 18 January 2007 (CST)
OK, I see your concerns here. I guess I felt that if the word chiropractic in the above was replaced by the word scientific I wouldn't have had a problem in that it wouldn't imply to me that the interpretation was questionable. This is what I mean when I say that I think we're reading into words things that weren't intended. It seems to me perfectly reasonable to say that these are the conclusions that this group of experts would draw, and that a different group of experts might not draw the same conclusions from the same evidence. Its not saying one is right and the other wrong. I'm an electrophysiologist;I put most emphasis on the type of data that I know and understand, because I think I can tell the difference between strong and weak evidence. For example a connection between two brain areas can be shown neuroanatomically or neurophysiologically. Now I'm more cautious sometimes about neuroanatomical evidence because I know that it has problems just as neurophysiological evidence has problems, but because I'm more confident about evaluating the strength of evidence from electrophysiology I'm more likely to feel able to draw a confident conclusion from that than from evidence in which I'm less of an expert. If you can't see something directly, you have to make an interpretation, and the interpretation you make is bound to be influenced by what you know and are confident about. Anyway, I'll look at this all more closely. We must maintain respect for different areas of expertise, but not be afraid to be straight where there are differences of interpretation, and present those differences honestly, fairly and constructively. I'm probably talking when I should be reading more.....Gareth Leng 18:05, 18 January 2007 (CST)
- I see what you mean, yes. Wow, it does read so much different looking through your eyes. Under those circumstances, I would be concerned that "does not involve any direct evidence of electrophysiological inhibition of nerve impulses" makes it sound like there is no possible way that any information is traveling along the nerve. Not being an expert in electrophysiologic inhibition, that sounds like the "end all" test to tell if there is nerve activity. It sounds contradictory - like chiropractors are calling it neural integrity, but it really isn't the nerve, that's just what they are calling it. Do you think maybe part of the problem is that we are looking at this through scientific magnifying glasses, when it is meant as a political definition. It's a consensus definition that lays claim to anything that is related to the spine and nerve to protect the practice of chiropractic for all it's different types of members. And we're trying to place scientific boundaries on an a definition that was meant to be all inclusive. What do you think? --Matt Innis (Talk) 21:59, 18 January 2007 (CST)
Yes, I think I'd agree. It seems to me that chiropractors use this concept to rationalise treatments that in their experience are effective. Doesn't seem to me to be anything wrong with that, its a plausible rationalisation, and a reasonable working assumption. However it is not one that will be generally accepted as the 'only possible' explanation without more direct evidence than practitioners can provide. My understanding, which may well be faulty, is that osteopaths for instance might look at the same signs and the same evidence and treat in a similar way but rationalise their treatment by its effects on blood flow. Also a plausible hypothesis, and not the only one.
No "direct evidence" of an effect on neural integrity to me means just that, that there is no direct evidence not that the conclusion is wrong. For me, as an electrophysiologist (experimental not clinical) what I understand by direct evidence needs electrophysiological recordings - you stimulate on one side of the injury, record on the other, and show that conduction is weak or slow. This is still not perfect, because when a motor nerve recovers from injury the way it innervates muuscle can develop abnormally - normally one motoneurone innervates a single muscle fibre, but a regenerating fibre can end up innervating several different muscle fibres; in this case the neural integrity is fully restored at the site of injury, but there is still functional loss as a result of the aberrant neuromuscular connection. I wouldn't be content with imaging data because on the one hand nerves can appear normal yet be hyper or hypoexcitable, and on the other hand there may be damage which is effectively compensated for.
In clinical cases, I know its often not practicable to support a conclusion abut the causes of disease with direct evidence. I don't know how often conclusions about the causes of conditions generally are in fact supported by direct evidence - not often I suspect. I think the important thing in this article is to make it clear that the concept of vertebral subluxation is how chiropractors prefer to explain why their treatments are effective, but that different health professionals prefer different explanations, and there is generally no direct evidence of a sort that would enable an objective decision to be made about which explanation is most correct. Gareth Leng 08:37, 19 January 2007 (CST) End of lead This concept is not used in conventional medicine, whose practitioners believe that the inference that neural integrity is impaired needs more direct evidence than the evidence accepted as sufficient in chiropractic, and who believe that there might often be other possible explanations of the signs and symptoms.??Gareth Leng 08:39, 19 January 2007 (CST)
I think you have a good grip on it. Can we say: From a purely scientific standpoint, the inference that neural integrity is impaired lacks the direct evidence necessary to be accepted as a mainstream medical concept, but chiropractors seem to use the it to explain why they feel their treatments are effective. --Matt Innis (Talk) 23:58, 20 January 2007 (CST)
Does my last change work?? for anyone??? Gareth Leng 09:50, 22 January 2007 (CST)
For me, no. Instead of wording that is simple and clear, there is a lot of confusing language. I have a hard time understanding it. Nancy Sculerati MD 12:23, 22 January 2007 (CST)
How about just plain: The inference that neural integrity is impaired lacks direct evidence, but nevertheless, chiropractors use it as a model to explain why their treatments seem to have effects on organ systems. --Matt Innis (Talk) 12:46, 22 January 2007 (CST)
Much better than mu tangled prose!!!!Gareth Leng 07:59, 23 January 2007 (CST)
- Back to this after a break, spotted a few minor glitchesand had a fresh look at the lead, but overall I think this must be close. Need the Flesia reference.Gareth Leng 04:00, 28 January 2007 (CST)
- I took a short one, too. I also made some clarifying changes in the middle - please check them over. It was more in line with Nancy's suggestions. Here's where I found the Flesia info. If you go back to the link before, you'll find the whole series of articles, but I think this is enough. You did an awesome job digesting it. I didn't mean for you to do it all, but I sure am glad you did:) I'll work my way down one more time tomorrow, then I think I'll be ready as well. --Matt Innis (Talk) 21:03, 29 January 2007 (CST)
Let's go through it together + discuss before making more changes
In the first line, spinal is hyperlinked, yet "spinal segment" is not. Now, I am not entirely familiar with this term: spinal segment. Matt- what exactly does it mean? (and thanks for the dog leap!) Nancy Sculerati MD 08:47, 31 January 2007 (CST)
- Spinal segment is a vestige of WP. Something about not using the word vertebra in the defintion. I am open to any other word you might want to use. --Matt Innis (Talk) 09:12, 31 January 2007 (CST)
Sorry, jumped the gun and changed to "section of the spine". Slapped my wrist and retreating now.Gareth Leng 09:49, 31 January 2007 (CST)
Please rewrite that sentence as you think best below, and we will go on from there. Let's not use boxing gloves, but kid gloves, and let's be very, very careful. :-) Nancy Sculerati MD 09:53, 31 January 2007 (CST)
- Something along these lines:
- Vertebral subluxation is a catch-all term used by chiropractors to refer to the many signs and symptoms that they suggest are the result of misaligned or abnormally functioning vertebrae of the spine.
- I am not happy with the word catch-all here, but I think it is an accurate description of how chiropractors use the word subluxation. See what you think.
Who wrote that- you, Matt? If you as a Chiropractor feel that is true-I can completely accept it. The great thing about it is that it avoids presenting an architectural definition of vertebral 'misalignment' that is at the heart of the conflict. We can work on coming up with language that is more elegant, in medicine, the conventional euphanism for "catch-all" is "nonspecific", though I think catch-all makes the meaning plainer. Let's at least get Gareth to weigh in, also. Nancy Sculerati MD 11:13, 31 January 2007 (CST)
I think that was Matt, and I think it expresses exactly the spirit of the concept as I've begun to understand it - its the name given to the those events that cause the things that spinal adjustments fix, so its existence is "defined" in effect, for any given case, by the fact of chiropractic's efficacy in treating that case. Its a catch-all, and why not.Gareth Leng 12:41, 31 January 2007 (CST)
Check it now, please. Add in links, and change first paragraph as you feel is needed. Nancy Sculerati MD 14:15, 31 January 2007 (CST)
- (edit conflict- wrote this before Nancy's post) Gareth - along the lines that you stated, this came from DD Palmer's 1911 book (this would be the last book he wrote right before he began with the really religious overtones - he died 2 years later):
- "In the history of the usual philosophies, sciences and arts, philosophy comes first, then science, and art last—a peculiar change in the revolution of ideas is ours —during the first three years of Chiropractic the first man only knew how to crudely push bones; later his followers began to reason how to do these things better; gradually, of course, and proportionally as the pupils paced the teacher the teacher followed the pupil, but it is only in the last three years that the why of Chiropractic has been worked out and made a practical foundation."
- I think that means what you just said. --Matt Innis (Talk) 14:24, 31 January 2007 (CST)
- As for catch-all. I have never heard any other chiropractor describe it as that, but I don't think anyone would fault us for it, though it would not hurt my feelings for it to find a synonym. --Matt Innis (Talk) 14:24, 31 January 2007 (CST)
I wrote a sample first paragraph without it for this reason- the problem , I think, is that in anatomy a subluxed vertebral joint has a specific meaning- having to do with physical arcgetecture, but in chiropractic the meaning is the inherent abnormailty of the spine causing the problem- there is no absolute "architectural" implication. Of course, I understand that the vertbal joint might be physically displaced or measureably compromised - but that is not a requirement. Nancy Sculerati MD 15:22, 31 January 2007 (CST)
Very close. Still missing something, though. --Matt Innis (Talk) 11:28, 1 February 2007 (CST)
This is what we have now:
- Vertebral subluxation is the term used by chiropractors for the underlying cause of the many signs and symptoms that they attribute to misaligned or abnormally functioning spinal vertebrae. The term is fundamental in chiropractic, and it indicates a concept rather than any specific anatomic relationship.
Maybe it needs to be simplified:
- Vertebral subluxation is the term used by chiropractors for the underlying cause of symptoms resulting from misaligned spinal vertebrae. The term is fundamental in chiropractic, and it indicates a concept more than any specific anatomic relationship.
--Matt Innis (Talk) 14:43, 1 February 2007 (CST)
- Vertebral subluxation is the term used by chiropractors for the underlying cause of symptoms that they attribute to misaligned spinal vertebrae. The term is fundamental in chiropractic, and it indicates a concept more than any specific anatomic relationship.
?Gareth Leng 05:23, 2 February 2007 (CST)
- That works perfectly for me! Nancy? --Matt Innis (Talk) 06:58, 2 February 2007 (CST)
This intro is preferred by me: Vertebral subluxation is the term used by chiropractors for the underlying cause of symptoms that they attribute to misaligned spinal vertebrae. The term is fundamental in chiropractic, and it indicates a concept rather than any specific anatomic relationship. I changed only one word- "more" to "rather", since -from what I can tell, a vertebral subluxation would be said to exist if there was someting "not right" about the feel of a back and there were complaints of pain or ill-health that existed,( either without being exacerbated by touching that area- and most certainly if those complaints were exacerbated by touching that area), even if every imaging test in the world showed that the vertebrae were normally aligned. If I have misconstrued, please say so- and try to get me to understand. NancyNancy Sculerati MD 08:24, 2 February 2007 (CST)
Okay, I see what you are saying. Then the problem seems to be with "anatomical relationship". I'll use osteoarthritis (OA) as an example as we are both familiar with it... If we consider that VSC includes all the stages of OA, then it is easy to see that imaging would show all the anatomic changes that occur with OA on Xray, MRI, etc.. However, there are stages that precede anything that can be seen on these imaging techniques(starting microscopically). Are these anatomical changes, too? These studies are also limited in their ability to evaluate the neurological elements that are occurring. Where do we draw the line as to what is considered an "anatomical" deviation. By using "rather" we seem to restrict VSC to a hypothetical time frame (that does not show imaging changes) while "more" includes this time frame as well as those that are visible. Is there a better way to say this? --Matt Innis (Talk) 10:00, 2 February 2007 (CST)
I don't think so, Matt. Can you live with it? Nancy Sculerati MD 10:03, 2 February 2007 (CST) addendum- 'rather' does not mean that anatomic changes are never there- it just means that they do not have to be there, in other words a vertebral subluxation in chiropractic terms does not depend on abnormal anatomy as necesary for the chiropractic diagnosis. Nancy Sculerati MD 10:05, 2 February 2007 (CST)
Your addendum definition certainly says what I am saying, so we must be thinking the same thing. Here are the definitions given by Answers.com for "rather":
- .More readily; preferably: I'd rather go to the movies.
- .With more reason, logic, wisdom, or other justification.
- .More exactly; more accurately: He's my friend, or rather he was my friend.
- .To a certain extent; somewhat: rather cold.
- .On the contrary.
My read was that it was saying "on the contrary". Are any of the other ones what we are trying to say? --Matt Innis (Talk) 10:54, 2 February 2007 (CST)
How about "instead of"? Vertebral subluxation is the term used by chiropractors for the underlying cause of symptoms that they attribute to misaligned spinal vertebrae. The term is fundamental in chiropractic, and it indicates a concept instead of any specific anatomic relationship. Is that ok with you? Nancy Nancy Sculerati MD 11:30, 2 February 2007 (CST)
"Instead of" still sounds like "on the contrary". How about if we add "to some". Its a little weaselly, but it allows for the "one or the other". Vertebral subluxation is the term used by chiropractors for the underlying cause of symptoms that they attribute to misaligned spinal vertebrae. The term is fundamental in chiropractic, and to some it indicates a concept rather than any specific anatomic relationship. --Matt Innis (Talk) 11:43, 2 February 2007 (CST)
What is the specific anatomic relationship that it implies to some chiropractors? Nancy Nancy Sculerati MD 11:46, 2 February 2007 (CST)
OK. I suspect that the answer might depend on the chiropractor. I know there are shades and subtleties, and sometimes these shades are either not seen at all or even if they are, it's not believed that words were chosen so carefully. Nebvertheless, adding "to some" impies an argument within chiropractic, so in what sense is it fundamental... :). So, I suggest.......
"The term is used extensively by chiropractors, and in several different ways, and to some it indicates a concept rather than any specific anatomical relationship. .
? I think they're all fine actually, I suspect that these nudges are all below the horizon. Is this the last remaining issue with this article? Surely not? Anyway, we should nominate To Approve to see if anyone else wishes to contributeGareth Leng 12:06, 2 February 2007 (CST)
Ahh, shucks, I didn't get to say "That depends on what your definition of is is?" :) Okay, Nancy, keep going through the article and I'll put the tag on it (If I can remember how to do it). --Matt Innis (Talk) 12:54, 2 February 2007 (CST)
