This is from my first EMG:

Polyneuropathy nerve conduction protocol was performed. Nerve conduction studies were performed in the right upper and lower extremities. Needle examination was performed in selected muscle groups in the right upper and lower extremities.

FINDINGS: Median motor amplitude is normal. Distal latency is prolonged, and conduction velocity is reduced. Median sensory amplitude is reduced, and distal latency is prolonged.
Median F-wave latency is essentially within normal limits of the estimate.

Ulnar motor amplitude is normal, distal latency is prolonged. Conduction velocity is also reduced. Ulnar sensory amplitude is reduced.

In the lower extremities, peroneal motor amplitude and distal latency are within normal limits, but conduction velocity is moderately reduced. Tibial motor latency is within normal limits, but distal latency is prolonged, and conduction velocity is moderately reduced.Tibial F-wave latency is within normal limits of the estimate however.

Sural sensory nerve conduction studies showed no response.

Needle examination of selected muscle groups in the upper and lower extremities showed evidence of mild chronic denervation affecting the distal muscle groups only.

IMPRESSION: this is an abnormal EMG, most consistent with a length dependent sensory motor mixed axonal/demyelinating polyneuropathy.
