Study of NCV and EMG

Variable Result
NCV
Muscle Stimulation site Latency (msec) Amplitude (mV)
ADM Wrist 6.6 (Prolonged) 4.0 (Reduced)
FDI DWC 4.1 2.2 (Marked Reduced)
Needle EMG
Muscle Insertional activity Spontaneous activity MUAP (duration) RP
ADM IIA F&P (+) Long R
FDI IIA F&P (++) Long Markedly R

NCV: nerve conduction velocity, EMG: electromyography, ADM: abductor digiti minimi, FDI: first dorsal interossei, DWC: distal wrist crease, MUAP: motor unit action potentials, RP: recruitment pattern, F&P: fibrillation potentials and positive sharp waves, R: reduced.
