Abstract |
Anconeus epitrochlearis muscle covering ulnar nerve has potential to compress it at the elbow. There has been no report that compromised nerve conduction velocity (NCV) recovered immediately after muscle releasing by electrical twitch obtaining intramuscular stimulation (ETOIMS). A 26-year-old male complaining of tingling pain on ulnar side of right hand visited our clinic. Electrodiagnostic study revealed decreased motor NCV of the ulnar nerve in the medial epicondyle of the humerus and 2 cm distal to it, suggesting cubital tunnel syndrome. Physical examination revealed tenderness in the anconeus epitrochlearis muscle, and Tinel’s sign was confirmed at the elbow. Assuming that the ulnar neuropathy had occurred by the anconeus epitrochlearis muscle, ETOIMS was performed to release it. Immediately after ETOIMS, motor NCV returned to normal and the tingling pain disappeared. This is the first case report, which electrophysiologically revealed the effect of ETOIMS on compressive neuropathy results from the muscle hypercontraction. |
