| NR, no response; CMAP, compound motor action potential; DL, distal latency; NCV, nerve conduction velocity; Amp, amplitude (peak-to-peak); SNAP, sensory nerve action potential; NDS, neurologic disability score. | ||||||||
| The skin temperature was kept above 32°C. Median nerve CMAPs and SNAPs were recorded with stimulus sites at the wrist and the elbow. | ||||||||
| Tibialis nerve CMAPs were recorded at the ankle and the knee. | ||||||||
