Abstract

We evaluated the elbow flexion test in 216 elbows without compression of the ulnar nerve at the cubital tunnel and without other neuropathies. We used Rayan's four positions as our test. The percentage of positive tests was only 3.6% at one minute, whereas evaluating the responses at three minutes we saw positive results in 16.2%. Therefore we find that if the test is performed for one minute it may be useful to help in diagnosing ulnar nerve compression at the cubital tunnel.
