NCV examination results for motor responses. The first NCV was performed on day 1 of admission while the second NCV was performed on day 5 of admission.

NCV = nerve conduction velocity; APB = abductor pollicis brevis; EDB = extensor digitorum brevis; TAM = tibialis anterior muscle; Amplitude P–P refers to CMAP amplitudere, it presents distance between negative-going wave peak and following positive-going wave peak.
