Neurophysiological results. No cMAP were recorded in both control group rats and in animals with collapsed prostheses. (Ai, Aii) The presence of the cMAP at the plantar muscles following sciatic nerve stimulation proximally to the implants was recorded in 24 of the treated rats. (B), (C) Mean cMAP amplitude as well as mean MCV (motor conduction velocity) are both significantly lower in the treated nerves in comparison with healthy contralateral nerves (p < 0.0001) showing a relatively early phase of nerve fibers regeneration and myelin repair after lesion. F-wave was recorded in 14 of the treated rats. (*) When detected in regenerated nerves, mean F-wave latency values are higher than in contralateral nerves.
