초록

Objective: The purpose of this study was to compare the diagnostic usefulness of various nerve conduction
studies when the routine median motor and sensory responses are absent.
Method: Between January 2002 and March 2008, 30 hands of 25 patients were studied, with the median
motor and sensory responses shown to be absent in the routine nerve conduction studies. We performed
three nerve conduction studies, median-radial latency difference to the thumb, median-ulnar latency difference
to the ring finger and the second lumbrical-interosseous latency comparison method.
Results: The subjects’ (3 men and 27 women) ages ranged from 32 to 84 years. All hands had no median
sensory response to the thumb and the ring finger. 5 hands had no median motor response to the second
lumbrical muscle. 25 hands showed a significant prolongation of the lumbrical-interosseous latency difference
(>0.4). In all the subjects, the needle EMG revealed abnormal spontaneous activity in the abductor
pollicis brevis.
Conclusion: The lumbrical-interosseous latency comparison method is helpful in patients with severe
CTS and with no median motor and sensory responses.
