Quote from article : "Foot orthoses are conventionally designed around the mechanical principle of supporting the medial longitudinal arch to alter plantar pressure and skeletal alignment. However, there is evidence that sensorimotor alterations may also be an important factor.The ?sensorimotor orthotic? paradigm has been proposed whereby foot orthoses are designed on the principle of altering sensory input to the plantar surface of the foot thereby changing muscle activation patterns"
As far as I've understood in the time spent on PA, the 'sensorimotor paradigm' is not well accepted in the podiatric community who has produced a definition of foot orthotics which is not based on 'supporting the medial longitudinal arch to alter plantar pressure and skeletal alignment'. Am I wrong ?
Daniel -
Who said these devices dont have a medial longitudinal arch on them?
-
While sensomotoric orthoses are not widely accepted in the podiatry community, they maybe in future. Up until a few years only rigid foot orthoses were accepted widely in the podiatry community in Australia. That has changed, many podiatrists are now using EVA or other non-rigid material in their orthotic therapy. I therefore think that podiatrists are open to look at alternatives and are not limiting themselves.
Sensomotoric foot orthoses are widely accepted in a number of EU countries, how is it in Rumania? -
Hi David
The paper you attach appears to show little effect on emg values and therefore that the 'sensorimotor' insoles are actually working primarily by mechanical means.
May be not the best paper to support a course on sensorimotor insoles? But fair play for not cherry picking :drinks -
I've participated last year at IVO Congress and I regret I couldn't met some people which I know from PA !
Daniel -
The problem in a normal clinical setting is determining how much of an effect is direct mechanical from orthotic reaction force and how much is cns motor mediated.
That said I would welcome thoughts as to how to optimise the sensory motor component of a prescription and where this might be put to good use. -

See this thread, there are a couple of references: http://www.podiatry-arena.com/podiatry-forum/showthread.php?t=75032

The attached study shows: "Increased activity of the peroneus longus
could be found in mid-stance with sensori-motor insoles. The change in muscle
activation patterns was statistically significant at 17.51?4.30 % stance phase and
reached its maximum at 29.67?4.51% with maximal values of 21.56?10.03%
MVC (Dummy 16.09?7.06% MVC)." Trouble is the bulk of the paper is not in English.
At the presentation, papers that are around will be discussed. Yes we will need more research that is no question, clinical case studies we have to discuss.Attached Files:

I went to a "sensorimotor orthotic" seminar yrs ago and the orthotics used had a great big lump under the sustenatculum tali --> all effects could easily have been mechanical -
yes a study we did with CMT and sensomotoric orthoses suggests a mechanical effect, see top of the post. Here is another study that showed a change in muscular activity:

Still I don't understand from these articles how the sensomotor insole is designed to stimulate the proprioceptors of the sole. In my understanding this is not explained in the sections "Material and Methods". It is a huge difference, for example, in the way in which Kirby is explaining how medial skive is working to increase the supinatory moment around STJA compared with the way in which the "five exclusive bars, including medial and lateral heel bars, a retro bar, a toe bar, and a lateral wedge" is altering sensory input to the plantar surface of the foot.
On the other hand there are evidences that foot orthoses has an effect on lower limb muscle activity. All of them are sensomotric ?

Effect of foot posture, foot orthoses and footwear on lower limb muscle activity during walking and running: a systematic review.
Murley GS1, Landorf KB, Menz HB, Bird AR.
Abstract
The aim of this systematic review was to evaluate the literature pertaining to the effect of foot posture, foot orthoses and footwear on lower limb muscle activity during walking and running. A database search of Medline, CINAHL, Embase and SPORTDiscus without language restrictions revealed 504 citations for title and abstract review. Three articles were translated to English and a final 46 articles underwent a two-tiered quality assessment. First, all articles were scored for their reporting of electromyographic methodology using a set of standards adopted by the International Society of Electrophysiology and Kinesiology. Thirty-eight articles displayed adequate reporting of electromyographic methodology and qualified for detailed review including a second quality assessment using a modified version of the Quality Index. These included six studies investigating the effect of foot posture, 12 the effect of foot orthoses and 20 the effect of footwear on lower limb muscle activity during walking or running. Meta-analysis was not conducted due to heterogeneity between studies. Some evidence exists that: (i) pronated feet demonstrate greater electromyographic activation of invertor musculature and decreased activation of evertor musculature; (ii) foot orthoses increase activation of tibialis anterior and peroneus longus, and may alter low back muscle activity; and (iii) shoes with elevated heels alter lower limb and back muscle activation. Most studies reported statistically significant changes in electromyographic activation, although these findings were often not well supported when confidence intervals were calculated. Most important, however, is that there is a need for further research of more rigorous methodological quality, including greater consensus regarding standards for reporting of electromyographic parameters.

Orthoes seem to have both a mechanical effect as well as a neuromuscular or sensomotoric effect. Many orthoses aim at the mechanical model to explain their function while the sensomotoric has a different aim. The latter is clearly less understood and needs more research. That makes it more interesting to me and makes attending a presentation from Lothar Jahrling very exciting.

Abstract
Background: Proprioceptive neuromuscular stimulating insoles are increasingly applied in treating functional complaints, chronic pain, foot disorders and so on.
Objectives: To evaluate rasterstereography as a tool in objectifying postural changes resulting from neuromuscular afferent stimulation and proprioceptive neuromuscular stimulating insoles and to compare the respective effects on posture.
Study design: This is a prospective experimental study.
Methods: A total of 27 healthy volunteers were consecutively exposed to six different varying intense neuromuscular afferent stimulating test conditions at three different times. One test condition featured proprioceptive neuromuscular stimulating insoles. In each test condition, a sequence of 12 rasterstereographic recordings of back shape was documented. Changes between six different test conditions and over time for 14 posture characterising parameters were investigated, for example, trunk inclination, pelvic torsion, lateral deviation of the spine?s amplitude or sagittal spinal curve.
Results: Standard deviation of our rasterstereographic measurements (?2.67 mm) was better than in most comparable reference values. Different neuromuscular stimuli were found to provoke significant changes to various posture parameters, including trunk inclination, pelvic torsion and so on ( each p < 0.001, F-tests). Proprioceptive neuromuscular stimulating insoles induced significant changes for parameter lateral deviation of the spine?s amplitude (p = 0.03).
Conclusion: Neuromuscular afferent stimulation and proprioceptive neuromuscular stimulating insoles induce postural changes, which can be detected reliably by rasterstereography.
Clinical relevance We demonstrated that rasterstereography ? a radiation-free imaging modality ? enables visualisation and documentation of subtle postural changes induced by varying intense neuromuscular afferent stimulation and the application of proprioceptive neuromuscular stimulating insoles.

Thank you for letting me know about this research. The concept that we referred to in this workshop is based on the work of Lothar Jahrling. His work is listed in the literature list of both articles. Lothar Jahrling first presented on this concept and his work in 1996 at a conference.
There is a connection as far as the concept is concerned for both articles and the workshop. However there is a difference in the foot orthoses individual material combination. It appears that both articles support the concept the workshop was about. I think another workshop is planned for 2017.
