Figs. 1-A and 1-B Electrophysiological studies of nerve conduction velocity (NCV) and distal latency after two to six weeks of chronic nerve compression (CNC) injury. The mean and standard error are plotted. N = normal (uninjured) nerve at 2 weeks. Fig. 1-A NCV in the nerves with a CNC injury showed a progressive decline until six weeks after injury; the normal nerve remained unchanged. Fig. 1-B Distal latency was prolonged after CNC injury. **P < 0.01. ***P < 0.001. ****P < 0.0001.
