a Nerve conduction studies performed 2 weeks after surgery of the right median nerve with stimulations at the wrist (A1) and elbow (B1) showing reduced amplitude of compound muscle action potentials (8.5 mV and 8.2 mV, respectively). The latencies and nerve conduction velocities were normal. b Needle electromyography of the right biceps brachii muscle performed 3 weeks after surgery showing reduced interference pattern
