Anterior interosseous nerve conduction studies were performed on 80 normal nerves of 45 healthy adult, The compound muscle action potential was obtained from the flexor pollicis longus by using the surface electrode, and from the pronator quadratus by using the needle electrode. We also calculated normal ratio of the flexor pollicis longus latercy to the abductor pollicis brevis latency, and the pronator quadratus latency to the abductor pollicis brevis latency, by dual channel recording.

The results of the conduction study form flexor pollicis longus were; latency 3.52 ⁑ 0.40 msec, amplitude 5.87 ⁑ 2.71mV, and anterior interosseous/median nerve latency ratio 0.49 ⁑ 0.04 msec, and the from pronator quadratus were; latency 4.12 ⁑ 0.50 msec, amplitude 25.49 ⁑ 10,10mV, and anterior interosseous/median nerve latency ration 0.57 ⁑ 0.05 Various anterior interosseous nerve conduction study methods were reviewed.

The anterior interosseous / median nerve latency ratio technique was easy to perform and useful in contolling patient's age, temperature, and systemic illness.

Key Words: Anterior interosseous nerve, Nerve conduction study, Flexor pollicis longus, Pronator quadratus
