METHOD: Of 640 volunteers screened, 26 LAA sides were finally included. Additional history taking revealed "minor symptoms" in some subjects. Minor symptoms do not qualify as a disorder because there is no interference with daily activities and no medical advice is sought. This study investigates whether the ULNT1 can (re)produce minor symptoms or abnormal responses in subjects with LAA. The EE-ROM was compared between the subjects' left and right side, and the subtraction angle-which is the effect of placing the cervical spine in contralateral lateral flexion-was compared between LAA sides and controls.

RESULTS: Langer's axillary arch sides showed a significant increase in the occurrence of minor symptoms and positive ULNT1, but no influence was observed on the EE-ROM.

CONCLUSIONS: These findings suggest that LAA may be capable of transiently provoking the axillary neurovascular bundle. The unaffected EE-ROM may be the consequence of a vascular origin of the minor symptoms or the consequence of an ulnar nerve/medial cord response to the ULNT1.
