Electrophysiological data
| Nerve conduction study | Distal latency | Amplitude | Conduction velocity |
|---|---|---|---|
| Ulnar CMAP | 3.9 (nl <3.6 ms) | 6.2 (nl >5 mV) | 42.6 (nl >48 m/s) |
| Median CMAP | 3.9 (nl <4.5 ms) | 5.0 (nl >3 mV) | 42.7 (nl >48 m/s) |
| Peroneal CMAP | 6.6 (nl <6.6 ms) | 0.48 (nl >2 mV) | 35.7 (nl >42 m/s) |
| Ulnar SNAP | NR (nl <2.1 ms) | NR (nl >11 μV) | |
| Median SNAP | 2.2 (nl <2.3 ms) | 27.2 (nl >40 μV) | |
| Sural SNAP | NR (nl <4.8 ms) | NR (nl >5 μV) |
NR=no response; CMAP=compound muscle action potential; SNAP=sensory nerve acation potential; nl=normal.
