Figure 2. Results of electrophysiological examinations in the gastrocnemius muscle following denervation and subsequent repair with different manners.

The CMAP peak amplitudes, motor nerve conduction velocities and proximal latencies among the four groups were compared. There were significant differences between the unprotected group and all other groups and between immediate-repair group and all other groups, but there were no differences between mixed-protected group and sensory-protected group (*p < 0.05 compared with unprotected control; **p < 0.05 compared with immediate-repair control).
