Thoracic outlet syndrome (TOS) is defined as a constellation of
clinical symptoms caused by the entrapment of neurovascular structures
(subclavian vessels and the brachial plexus) en route to the upper limb via the
superior thoracic outlet. Nonspecific neurogenic TOS is not easy to diagnose
because there is no investigational technique that has proven to be the
diagnostic gold standard. DESIGN: In this study, our aim was to investigate the
role of provocative F response in the diagnosis of nonspecific neurogenic TOS. F
wave analysis of median and ulnar nerves in neutral and provocative maneuvers was
carried out in 21 patients with a clinical diagnosis of nonspecific neurogenic
TOS and in 15 healthy volunteers. RESULTS: All findings were within reference
range in both groups, and no statistical difference was noted among subject
groups, with or without provocative maneuvers. CONCLUSIONS: We conclude that the
nonspecific neurogenic TOS is a temporary compression process that does not
result in a structural damage on the nerve; therefore, significant
electrophysiologic changes are not elicited.
