Mj. Kothari et al., MEDIAL ANTEBRACHIAL CUTANEOUS SENSORY STUDIES IN THE EVALUATION OF NEUROGENIC THORACIC OUTLET SYNDROME, Muscle & nerve, 21(5), 1998, pp. 647-649
Over 3 years, we studied 8 patients with neurogenic thoracic outlet sy
ndrome (TOS) and tested the medial antebrachial sensory response (MASR
) to determine its diagnostic value. The MASR and ulnar sensory respon
se (USR) were abnormal in all 8 patients. Seven had a low median motor
response (MMR) with a low USR. In 1, the MASR and USR were abnormal b
ut the MMR was normal. We conclude that the MASR is of diagnostic valu
e in patients with neurogenic TOS. (C) 1998 John Wiley & Sons, Inc.
