Latency
(ms) |
Amplitude (µV) | Velocity (m/s) | |
| Median | Right | ND | ND | ND | |
| Ulnar | Right | 2.5 | 0.3 | 41.4 | |
| Sural | Left | 2.2 | 6.5 | 68.5 | |
| Sural | Right | 2.4 | 11.9 | 66.0 |
For motor studies, distal and proximal amplitudes are presented in this order; for each, stimuli were delivered at the wrist and elbow (upper limb) or at the ankle and knee (lower limb). ND: not detected
