Abstract:
Objective To investigate the clinical and electrophysiological characteristics of cubital tunnel syndrome (CTS). Methods The clinical and electrophysiological data of 150 cases of CTS involving 173 upper limbs (UL) were collected. And the electrophysiological data of 76 healthy subjects were also collected. The data of EMG between the two groups were compared and analyzed statistically. Results Fibrillation potentials were detected in 114 and 91 UL, respectively, in abductor digiti minimi, and positive sharp waves in 50 and 48 UL, respectively, in the first dorsal interosseous muscle. The average conduction velocity of the ulnar nerve was decreased, with motor conduction velocity(MCV) from above to below elbow 34.6?9.75 m/s and sensory conduction velocity (SCV) 45.99?9.65m/s; the motor latency was prolonged and amplitude of motor action potential decreased. There was statistical difference between the patients and the healthy control groups ( P
