Figure 2. The joint region of the median nerve experiences more strain than the non-joint region.

Median nerves were extended in situ by limb movement (A) or stretched after excision (B). Local strain at two regions showed the same distinctive difference both in situ and ex vivo. Data are means ± s.e.m., n = 5 or 6 nerves for A and B, respectively, P = 0.02 and 0.006, respectively (paired t test).
