Shalom again
Some 2 weeks ago I sent the following to the net:
************************************************** *********
Shalom to all netters
We need some urgent help in the following, and could not find anything
useful in the literature available to us.
We are looking into peripheral nerve regenerayion following severe
damage and the effect of various treatments. The model is the sciatic
nerve in rats. I am looking for a simple but reliable and acceptable
method to assess mechanically / visually the recovery. I was trying to
sqeeze the mid-finger while recording the foot movement using video, but
it was too slow (I don't have high speed video). Of course we are
running EMG and histologic tests as well, but the mechanical aspect is
my project.
I wonder if anyone came across any simple solution to this question.
************************************************** ************
Thanks to all those that send me their replies and comments. I got a
number of requests from other interested colleagues, and I hope this
message will get to them.
3 replies suggested the use of compound action potential as a main and
sole test (Sun G. Chung suncg@medicine.snu.ac.kr , Dr. Goss Sampson
M.A.Goss-Sampson@greenwich.ac.uk and Joe Spadaro
spadaroj@hscsyr.edu). We are running this test as I mentioned in my
letter.
Eling de Bruin (debruin@biomech.mat.ethz.ch) suggested the following
thesis:

chronic
stress in the rat. By: Nico van Meeteren Thesis Universiteit
van Utrecht, 1994 ISBN 90-393-0625-7

The standard method is to measure changes in toe spread and step length;
the 1997 reference below uses the method, while the earlier papers are
on the method itself. There is a parallel evaluation procedure for
peroneal
nerve regeneration which our laboratory at Stanford Univ/Palo Alto VA
Rehabilitation R&D Center has used more often.

And that's about it so far. We will be happy to receive any further
information.
