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.
