EMG. Findings: The right median and ulnar motor nerves revealed normal distal latencies, amplitudes, and conduction velocities. The right median and ulnar sensory nerves revealed normal distal latencies, amplitudes, and conduction velocities. Needle examination was performed with a monopolar disposable needle electrode on the muscles indicated above. Impression: The above electrodiagnostic study is compatible with a severe, axonal, peripheral neuropathy involving the right upper extremity.
