The nerve conduction studies, F-waves and dermatosomal and lor somatosensory evoked potential have a low level of sensitivity for Thoracic Outlet Compression Syndrome (TOCS) diagnosis. A standard negative electrodiagnostic study does not exclude the presence of TOCS.
The purpose of this neurophysiological note is that the Wright's hyperabduction, costoclavicular compression and Adson's scalenus tests important in making a clinical diagnosis of TOCS can be used as neurophysiological provocative maneuvers to determine the effect of braquial position on electrodiagnostic parameters.
Nine selected TOCS patients were evaluated previous and following provocative maneuvers for 3 and 6 minutes.
The results showed a positive electrodiagnostic study in 7/9 patients.
It is suggested that patients with presumptive TOCS and negative electrodiagnostic findings be reevaluated immediately after 6 minutes of Wright's, Adson's or costoclavicular compression provocative tests.
神经传导研究、F波以及皮节和躯体感觉诱发电位对胸廓出口综合征（TOCS）诊断的敏感性较低。标准的阴性电诊断研究不能排除TOCS的存在。
本神经生理学报告的目的是，在TOCS临床诊断中具有重要意义的赖特氏过度外展试验、肋锁压迫试验和阿德森氏斜角肌试验，可作为神经生理学激发动作，以确定臂部位置对电诊断参数的影响。
对9例选定的TOCS患者在激发动作前后分别进行3分钟和6分钟的评估。
结果显示，9例患者中有7例电诊断研究呈阳性。
建议对疑似TOCS且电诊断结果为阴性的患者，在进行6分钟的赖特氏、阿德森氏或肋锁压迫激发试验后立即重新评估。
