Do the skin's proprioceptors (or a few of them) detect movement in a preferential direction such as fascia fiber orientation, muscle fiber orientation or do they equally respond to stretch in every direction?
I search data about mapping of mechanical receptive filed of the skin in whole body, and i wonder if the response of mechanical receptors is direction-dependent.
It's in order to understand effect of skin strech in different parts of the body.
Hi Laurent, I presume you know dr. Guimberteau's work. He shows us that skin has perfect tissue memory and will (once stretched either intrinsicly or extrinsicly) come back to its original state. Extrincic stimulus can be tape or vibration, intrinsic heartbeat and lymph flow are sufficient to 'move' the skin. If you really want to dig into the skin I suggest you join the www.somasimple.com group...... lots of information about the skin and brain on this fórum.
Yes, I have Two of his DVDs and I saw some of his conference in osteopathic congress. It helps to understand how tissus move one relative to each other. It's a very interesting functionnal approach of the human tissue. It's more realistic than the anatomic vision of different layer with virtual space of sliding.
I'm going to take a look to this group.
But it's doesn't explain how the nervous system detects the direction of the strech and if a prioprioceptor detects preferentially one direction relative to the other direction. I find few articles about mapping mechanical receptive field but it is more about hand than the other part of the body.
please Laurent,
You will need some spare time so take a week off, go to the somasimple website or to Diana Jacobs blog http://humanantigravitysuit.blogspot.com/
and take time to read everything that has been written there. :)
I am pretty sure you will find your answer there.
The CNS knows (through physiological 'law' of movement of the skin), in which direction the skin moves....colleague T.Ben Fukui presented on this subject at the WCPT conference 2011 in Amsterdam. You can find his poster there....
go to http://www.abstractstosubmit.com/wpt2011/abstracts/ and search for: nr RR-PO-203-1- thurs or add words skin physiological movement and you should be able to find the abstract and poster on the tracking of skin movement in the trunk...
I would look at Simon Gandevia's work on mechanoreceptors. He also did a recent (2012), very extensive review with Uwe Proske: THE PROPRIOCEPTIVE SENSES: THEIR ROLES IN SIGNALING BODY SHAPE, BODY POSITION AND MOVEMENT, AND MUSCLE FORCE that might contain some references to help answer your question.
As Esther has already suggested, Diane Jacobs' site is a goldmine of information about the biology of the skin, particularly with regards to its clinical relevance in manual therapy. She currently doing a series on "How Manual Therapy Works". Part 5 is titled: TACTILE DIRECTION DISCRIMINATION IN THE DORSOLATERAL PREFRONTAL CORTEX. It's very refreshing to see a clinician discussing manual therapy from a scientific perspective.
Thank for all, Esther. I went on the forum somasimple, i find very good informations.
Thank for the article John, i find it and i am going to read it during this week.
I find part of the answer of my question in a very interesting book, it is : Martin Grunwald, Human haptic perception, Basics and applications, Birkhaüser Verlag: Berlin, 676p.
The most of the book is about human hand, but it gives me some new ideas to my research.
There is a good article too (http://jn.physiology.org/content/65/3/657) : B. B. Edin , J. H. Abbs, Finger movement responses of cutaneous mechanoreceptors in the dorsal skin of the human hand, Journal of Neurophysiology, published 1 March 1991, Vol. 65no. 657-670.
