Obturator Nerve Conduction Study Using Magnetic Stimulation in Healthy Adults

ABSTRACT

OBJECTIVE: To get the mean values of obturator nerve conduction from 20 healthy adults. METHOD: Magnetic stimulation of the stimulated paralumbar area of the 3 to 4 root levels with needle electrodes placed in adductor brevis muscle and adductor longus muscle for both sides for recording. RESULTS: The mean latency was 5.44+/-0.91 msec in the right adductor brevis muscle, 5.70+/-0.62 msec in the left adductor brevis muscle, 5.49+/-0.73 msec in the right adductor longus muscle and 5.61+/-0.70 msec in the left adductor longus muscle. There was no significant difference between adductor longus and adductor brevis muscles for the mean latency. The mean amplitude was 11.26+/-4.10 mV in right adductor brevis muscle and 11.65+/-4.20 mV in left adductor brevis muscle, and 11.14+/-3.58 mV in right adductor longus muscle and 11.01+/-3.18 mV in left adductor longus muscle. There was no significant difference between adductor longus and adductor brevis muscles for the mean amplitude. CONCLUSION: Obturator nerve conduction study using magnetic stimulation can be a useful tool for the evaluation of obturator nerve injury.
