Highlights 1. The triple stimulation technique (TST) was assessed in the diagnosis of neurogenic thoracic outlet syndrome (TOS). 2. By combining the TST amplitude ratio and central motor conduction time, the compression site of neurogenic TOS can be located. 3. The decreased amplitude ratio revealed the existence conduction block in neurogenic TOS besides axonal loss.
Abstract Objective: We assessed the diagnostic value of triple stimulation technique (TST) in eight neurogenic thoracic outlet syndrome (TOS) patients by revealing the conduction block of the proximal lower-trunk of brachial plexus and locating the compression site. Methods: Eight patients fulfilling the conventional criteria of lower-trunk neurogenic TOS were enrolled in our study. TST along with central motor conduction time was evaluated. The parameters including the TST amplitude ratio and TST area ratio were compared between patients and controls. Results: The amplitude ratio was significantly lower in the patient group than the control group (patients: 0.518±0.113; control: 0.954±0.020, P
