The median nerve also serves the abductor pollicis brevis, the opponens pollicis
, and the superficial head of the flexor pollicis brevis; involves the muscles to the thumb (Li, Harkness, & Goitz, 2005); and is the most specific motor assessment for CTS.
Bilateral biceps, brachioradialis, and triceps muscle stretch reflexes were tested, as were bilateral muscle strength in the biceps, triceps, deltoids, and opponens pollicis
There was 3+/5 motor strength of the bilateral APB and opponens pollicis
, but otherwise there was normal (5/5) motor strength testing of bilateral shoulder, elbow, forearm, wrist, and hand motions, and there was no atrophy or clonus noted in BUE.
