A neurophysiologic investigation of thoracic outlet syndrome.
Earlier reports have been conflicting as regards the value of neurophysiologic measurements in the diagnosis of thoracic outlet syndrome (TOS), presumably due to differences in selection of patients and in selection and standardization of neurophysiologic tests. The object of the present study was to assess the value of extensive conventional neurophysiologic measurements for the diagnosis of brachial plexus compression in patients with clinical TOS as determined from standardized criteria. The results are discussed in the light of expected neurophysiologic findings at different degrees of brachial plexus compression.
