(A) Polyphasic and short duration myopathic motor unit potentials (MUPs) with quantitative needle electromyography of the biceps brachii muscle. Normal mean duration of all potentials (11.7 ms) (27% polyphasia) but shortened duration of simple potentials (9.4 ms, lower limit of normal: 9.8 ms), (B) synchronous and smooth long duration compound muscle action potentials (CMAPs) in median nerve with normal distal motor latency (DML) and conduction velocity (CV), (C) right median motor F-waves: 20 trials of supramaximal stimulation delivered at 1/s, before a 20 Hz repetitive nerve stimulation (RNS) showing absent F-waves, (D) normal latency and frequency of F-waves after 20 Hz RNS.
