Of three signs in carpal tunnel syndrome, Phalen's, Tinel's and the Flick sign, the last of these was the most valid and reliable. The presence of a positive Flick sign predicted electrodiagnostic abnormality in 93% of cases and had a false positive rate of under 5% among other neural lesions in the arm. The key question consists of an enquiry as to what the patient does with the affected hand at times when symptoms are at their worst; a flicking movement of the wrist and fingers demonstrated by the patient constitutes a positive response.
在腕管综合征的三个体征，即Phalen征、Tinel征和弹拨征中，弹拨征是最有效且可靠的。弹拨征阳性在93%的病例中预示着电诊断异常，在手臂其他神经损伤中假阳性率低于5%。关键问题是询问患者在症状最严重时受影响的手会做什么；患者表现出的手腕和手指的弹拨动作构成阳性反应。
