  • Geoff,
    I think we have explained several times it is the why that we are concerned with, not the results. We have all seen "GREAT RESULTS" from our own work and from everyone selling or using a system. If you aren't interested in "why" then there isn't going to be much here for you.


    and the rest:

    I haven't seen much about Z-health theory, except what I've seen here but let me give it a shot. First, we need to accept the presence of the withrdrawal and startle reflex. The body is an organism geared to survival and it has inherent reflexes to protect itself. The startle reflex, for example is part of our fight or flight programming to cover up vital areas, it generally involves movements that we would consider flexion. In todays society we are often inappropriately activating the startle reflex without resolving the issue, and we are left in a "chronic startle state" (flexion), withdrawal can lead to a similar tightness caused by extension and the patterns can be observed for each. We also have a righting reflex, it keeps us upright and straight, it relies heavily on the visual system. We largely orient are bodies according to what we see, the eyes will seek to remain level, if they become unlevel, either due to dysfunction of either the eyes themselves or postural changes, (twisted pelvis, unlevel shoulders, forward or bent head position) the body will attempt to compensate to return them to level or to orient itself by the righting reflex to what it believes is upright given the input from the eyes. The next concept we need to understand is the integration of the whole body, each part affects the whole, the part where the dysfunction is felt is not necessarily the part that is actually the cause. There are some predictable and testable patterns that can be observed, people usually exhibit lateralization, and there are things such as Janda's crossed syndromes or that people sometimes walk swinging the same hand and leg together during walking. If we correct the pattern, we correct the dysfunction. One of the results of chronic withdrawal or dysfunctional movement patterns is activation of the arthrokinematic joint reflex (AJR), or joint protective reflex. This can be activated either by chronic dysfunction or by an acute episode, such as a sudden stretch, and it fails to resolve. If we take all the joints through their active ROM, in all planes and at different speeds, the nervous system recognizes that previously inhibited joint motion can now be moved safely. Once the nervous system recognizes the fact that all joints are healthy, the AJR is inhibited, allowing whole body movements to be done correctly and smoothly.

    I could jazz it up some with terms like Type 1 and 2 afferents, cascading hormonal responses, oculocomotor, etc. but it would remain the same. Does it look familiar? Because to everyone on this list that has been here awhile it does. It is the simplified version of the same explanations that every other system gives, and it is, at best, surface dressing.

    On the other hand, I came across z-health quite some time ago from Supertraining, at that time it just billed itself as an exercise system and I thought, and think, it was a good idea. It worked on things like body awareness, balance, flexibility, coordination and other attributes that were more neurological than muscular and I thought it was a good step in a direction that was largely being ignored. Scott Sonnon's Bodyflow, Egoscue's Patch, ProbodX, Crossfit were other systems that worked in more or less the same way and I liked them all to some degree. So I am not a critic of the system, for exercise, my criticism lies in the advertisement and claims I now see being made of it. That it is not only a treatment for medical and painful conditions, but that they border on the incredible. Extraordinary claims demand extraordinary proof but I have seen no evidence, other than testimonials which every other system, even the most bizzare have plenty of. Exercise geared to them is beneficial to most people's pain states, so is self efficacy, motivation, touch, placebo, etc. What is needed is an explanation, of why z-health is different than other systems. What mechanisms are involved and how do you know this? How do you know the reliability and validity of your testing or even of your results?

    Answers given as if parts of the system are already accepted aren't helpful. For example, we would open up the joints and then test the gait, the gait test showed great improvement. Neither the opening of the joints or the gait test has been show to have any validity yet, so referring to either isn't helpful.

    Let me say that I know it is difficult to be in the position you are in now. You are facing what seems to be a difficult crowd. Understand, that you are not the first person to present this forum with a similar system based on similar evidence. If we are a bit impatient and maybe even short tempered about it, it isn't a result of this thread alone but also of many others and for some, over many, many, years. (I'm not calling anyone old, but some here ask "which one?" when you talk about what they were doing at the turn of the century).

    Frankly, I don't have high hopes for this thread going anywhere, my only hope is that it remains friendly enough, or that everyone involves has the intellectual curiosity, to remain on this forum when its done.

    • In the beginning of this thread, I asked specific questions, that went largely unanswered. I should NOT have posed them: instead I should have asked:
      "What is DIFFERENT about this approach, in its effects and workings, to justify the course fee?"
      Physiology is the same for all; as are neuroanatomy, and neurophysiology, and arthrokinematic principles, and brain structure and function (largely)..... So WHAT is so different about this that it requires big $$ to learn?

      • Bas,

        Great question. Asking for money from others if they want to be in your presence while learning what you might teach them is a complex and potentially corrupting thing - and I would know.

        For the record, my own one day workshops go for $199.00, a fee that can drop to $149.00 if you attend with friends or colleagues. That's for everything I know in 6 hours. Personally, I receive a small percentage of this fee, the rest going to Cross Country Education.

        After over 30 years of watching these fees grow and classes fill (or not) I am convinced that people are paying you for two things: promises of power and rituals they find magical and entertaining. I'm not certain that there's any real teaching or learning necessary.

        Given that, I'll let you guys figure out how it is the "Z" system manages to command such a high fee.

        • Thanks Barrett. Maybe if you'd charge $2,000, you'd have a true flock of adoring followers too....

          One more thing that bothers me (and trust me, the list is long):
          "What's the number one criteria? Performance."

          For athletes maybe. For practitioners who are getting success in their own way, the number one criterium for adopting other methods is higher scientific plausiblility and/or evidence of a better level......than anecdotal or "experience".

          I can not help but tell my old story to the new ones here:
          Chronic (24 yr +) thoracic pain, never obtained relief with MFR, HVLA, CST, injections, exercises, ART, cranial osteopathy etc etc...obtained lasting relief when being taken through "past-life regression therapy" while being "emotionally unwound" simultaneously.


          Based on your concept, Mike, I should not really ask "how, what, why" or "ARE YOU CRAZY?!?!", but chalk this up to experience and go with past-life regression as my choice of treattment for chronic pain..........

          • Randy, I believe that's the most I've ever seen you write all in one place, ever. It answered a few puzzles for me, so thanks. I concur with "Answers given as if parts of the system are already accepted aren't helpful", and your observation, "So I am not a critic of the system, for exercise, my criticism lies in the advertisement and claims I now see being made of it. That it is not only a treatment for medical and painful conditions, but that they border on the incredible. Extraordinary claims demand extraordinary proof"

            On the other hand, "(I'm not calling anyone old, but some here ask "which one?" when you talk about what they were doing at the turn of the century)." - I don't think anyone here is over 107.. at least one of us was born in the first half of the last century though.

            • Everyone,

              Thanks for taking the time to read and post on this subject. This has been an enlightening experience for me.

              My take home lesson from all this is: How much "why" do I have to know, do I want to know, do I want to spend time learning, based on my current life situation? My immediate answer is, "I'm not sure." But it definitely gives me food for thought--and I'm always hungry.

              I will not be posting again on this subject because it's time-intensive and I have other things I'm "supposed" to be doing.

              Thank you, Mr. Dorko, for providing this forum. I will continue to peruse it because it appears to be an outstanding resource for learning. Perhaps I will make it to your seminar when you pass by my way.

              Thank you again.

              • Geoff, you are a gentleman and a scholar, based on that last post. You are welcome anytime to exercise robust thought as well as 'cuboid joints'.

                One small perception correction: the forum is provided/maintained/administered by someone else (with the same initials BD, however...) i.e., Bernard Delalande, based in France.

                          and that should raise interest, not build moats and drawbridges to defend territory.

                          • To answer a question from some time back, it is just referred to as the "cuboid joint" since the cuboid area is the target area for the Z Health drill called an outside toe pull. Technically (which you know) the cuboid is an actual bone and not a joint space as it border the 5th metatarsal, calcaneous, etc. Sorry if that caused any confusion.

                            Randy's post is basically correct. Yep, that is the basis for many systems I am sure. I have not studied a lot of other systems, so I can't say for sure. Maybe you should save that post and just put it up when someone from another system pops on here and head 'em off at the pass?

                            One of the questions was, "what is a Z Health drill" which is a fair question. Below is he description of a middle toe pull and an outside toe pull. Taken from an article on Dynamic Joint Mobility training from http://www.t-nation.com/readArticle.do?id=1135077

                            The Middle Toe Pull: Begin in neutral stance, reach your leg behind your body, and curl the toes under with the knee in a neutral position. Use the knee and foot position to create a "stretching" mobilization just below the ankle in the target area pictured.

                            Once positioned correctly, perform five slow mini-squats (three to five inches) with the front leg. If you're doing this correctly, you should feel a strong stretching sensation in the target area.

                            The Outside Toe Pull: Begin in neutral stance, reach your leg behind your body, and curl the toes under with the knee in a neutral position. Let your ankle fall to the outside of your body and then use the knee and foot position to create a "stretching" mobilization just below the ankle in the target area pictured.

                            Once positioned correctly, perform five slow mini-squats with the front leg. Again, if you're doing this correctly, you should feel a strong stretching sensation in the target area.


                            There is not one joint that will ALWAYS be right to mobilize, as each person is different. In general, Z Health drills that focus on the ankle/feet, spine and hips are the most effective due to the higher concentrations of mechanoreceptors in those areas. A few studies below on that--the last study showing a change in the number of mechano vs noci after lumbar fusion. A drill is tried and then the athlete is re-assessed.

                            I don't know any studies that have been done on gait and feet width as an indicator for efficiency. One definition of gait efficiency is energy cost per distance traveled (Nielsen, DH et al). Traditionally, energy expenditure is assessed by oxygen uptake monitoring and is calculated from the ratio of oxygen uptake to walking velocity and is expressed in milliliters of oxygen per kilogram body weight per meter traveled. There may be a study using vertical ground reaction force related to efficiency, but again, I could not find one.

                            Ref
                            Nielsen DH, Shurr DG, Golden JC, Meier K: Comparison of Energy Cost and Gait Efficiency During Ambulation in Below-Knee Amputees Using Different Prosthetic Feet-A Preliminary Report. Journal of Prosthetics and Orthotics 1:24-31, 1989.


                            In response to what is different about this course to justify the cost--well, the cost in my opinion is partially set by what the market (people will pay). That is a whole debate in its self, but for myself the benefit was a system that I could use and learn in a short period of time. Most people who take the Z Health class are not well versed in neurophysiology at the start. Most want a system that they can use with their athletes to enhance performance, test outcomes and get results.. Yes there are many systems out there to pick from. I am sure many could have arrived at similar conclusions on their own after much study and time, but time is a non renewable resource and if I can learn the material (even if it is at a high level) in a short period of time and put it to use the next I get back, that is worth a fair amount of money to me.

                            None of this was intended for any marketing purpose and nobody who contributed to this post is on the "Z Health payroll" or anything like that. We were just trying to help out as best as we could.

                            Maybe there is a cheaper and better version out there that everyone will be doing instead in time? Perhaps, and time, research and more discussion will tell. Maybe the answer is Simple Contact. I will try my own "experiments" with it and keep learning.

                            I do really appreciate everyone's opinion on time spent on this topic. In the end, all of us are just trying to help others as best we can and it is a process/journey for each person.

                            I too have to attend to other things (business, work, looks like I might have some money to start my research--yeah, etc), but I will try to peruse by when I can and post anything interesting that I find. I have enough book references from this thread and Barrett's presentation to last me quite some time.

                            One question, if you were me, where would you recommend that I start? I have many ideas, but I am open to your input. I have Barrett's course workbook and we will reviewing that again of course, along with my 12 pages of notes I took when he was here in MN.

                            Thanks again to everyone for their time once again. I wish all of you continued success in your future endeavors.

                            Sincerely,
                            Mike T. Nelson

                            McLain RF.

                            Department of Orthopaedic Surgery, University of California, Davis, Sacramento.

                            Twenty-one cervical facet capsules, taken from three normal human subjects, were examined to determine the type, density, and distribution of mechanoreceptive nerve endings in these tissues. Clearly identifiable mechanoreceptors were found in 17 of 21 specimens and were classified according to the scheme for encapsulated nerve endings established by Freeman and Wyke. Eleven Type I, 20 Type II, and 5 Type III receptors were identified, as well as a number of small, unencapsulated nerve endings. Type I receptors were small globular structures measuring 25-50 microns in diameter. Type II receptors varied in size and contour, but were characterized by their oblong shape and broad, lamellated capsule. Type III receptors were relatively large oblong structures with an amorphous capsule, within which a reticular meshwork of fine neurites was embedded. Free (nociceptive) nerve endings were found in subsynovial loose areolar and dense capsular tissues. The presence of mechanoreceptive and nociceptive nerve endings in cervical facet capsules proves that these tissues are monitored by the central nervous system and implies that neural input from the facets is important to proprioception and pain sensation in the cervical spine. Previous studies have suggested that protection muscular reflexes modulated by these types of mechanoreceptors are important in preventing joint instability and degeneration. It is suggested that the surgeon take steps to avoid inadvertently damaging these tissues when exposing the cervical spine.

                            STUDY DESIGN: Histologic analysis of normal human facet capsules to determine the density and distribution of encapsulated nerve endings in the thoracic and lumbar spine. OBJECTIVES: To quantify the extent of mechanoreceptor innervation in normal facet tissues and determine the relative distribution of three specific receptor types with respect to thoracic and lumbar segments. SUMMARY OF BACKGROUND DATA: Ongoing studies of spinal innervation have shown that human facet tissues contain mechanoreceptive endings capable of detecting motion and tissue distortion. The hypothesis has been advanced that spinal proprioception may play a role in modulating protective muscular reflexes that prevent injury or facilitate healing. METHODS: Whole facet capsules harvested from seven healthy adult patients were processed using a gold chloride staining method and cut into 35-micron sections for histologic analysis. No sampling was performed; all sections were analyzed. Receptor endings were classified by the method of Freeman and Wyke if they met the following three criteria: 1) encapsulation, 2) identifiable morphometry, and 3) consistent morphometry on serial sections. RESULTS: One Type 1 and four Type 2 endings were identified among 10 thoracic facet capsules. Five Type 1, six Type 2, and one Type 3 ending were identified among 13 lumbar facet capsules. Occasional atypical receptive endings were noted that did not fit the established classification. Unencapsulated free nerve endings were seen in every specimen, but were not quantified. CONCLUSIONS: Encapsulated nerve endings are believed to be primarily mechanosensitive and may provide proprioceptive and protective information to the central nervous system regarding joint function and position. A consistent, but small population of receptors has been found previously in cervical facets, but innervation of the thoracic and lumbar levels is less consistent. This suggests that proprioceptive function in the thoracic and lumbar spine is less refined and, perhaps, less critical than in the cervical spine.

                            Effects of anterior lumbar spinal fusion on the distribution of nerve endings and mechanoreceptors in the rabbit facet joint: quantitative histological analysis.

                            The purpose of this study was to investigate the density and distribution of neural endings in rabbit lumbar facet joints after anterior spinal fusion and to evaluate the effects of intervertebral immobilization. An extraperitoneal approach was applied, and L5/6 was fixed with a plate and screws. Bilateral L4/5, L5/6, and L6/7 facet joint capsules were harvested from the rabbits 4, 8, and 16 weeks postoperatively. Capsular tissues were processed using a modified gold chloride staining method, and the specimens were sliced into 15-micro m sections. All sections were analyzed microscopically, and neural ending numbers per unit volume were calculated. Three types of neural ending were identified in each specimen: Pacinian corpuscles, Ruffini corpuscles, and free nerve endings. In the L5/6 fusion segment there was a significant decrease in the number of Pacinian corpuscles at 4 weeks and of Ruffini corpuscles at 4, 8, and 16 weeks after the fusion compared with the control; and in the L4/5 upper adjacent segment there was a significant increase in the number of free nerve endings. The number of Ruffini endings for the L6/7 lower adjacent segment was significantly lower more than 8 weeks after the fusion. These results suggest that immobilization of the intervertebral segment causes a reduction in the number of mechanoreceptors in the facet joint capsules because of the reduction in mechanical stimulation. Moreover, in the upper adjacent facet joint there may be neural sprouting caused by nociceptive stimulation.

                            • Hi Mike,

                              I've got some fair questions. Is the outside toe pull supposed to accomplish anything in particular or is the effect non-specific? Does the outside toe pull accomplish something that middle toe pull doesn't?
