• Description:
  The ability of vibrometry to detect carpal tunnel syndrome (CTS) was evaluated. The study group consisted of 119 volunteers, 238 hands, who were divided into three groups according to the presence or absence of CTS symptoms and abnormalities in sensory nerve conduction as measured by standard electrophysiological techniques. Fifty seven hands had symptoms and electrophysiological findings typical of CTS (CTS positive group), 58 hands had CTS symptoms, but normal electrophysiological findings (CTS negative group), and 123 hands had no CTS symptoms and normal electrophysiological findings (controls). The subjects performed 10 minutes of wrist flexion exercise. Vibrotactile thresholds (VTs) of the index and small fingers of both hands were measured before and after exercise using a Vibraton-II instrument. VTs in CTS patients measured after 10 minutes of wrist flexion averaged twice those measured before such exercise. After wrist flexion, sensitivities were 61 and 57% for specificities of 70 and 80%, respectively. [Description provided by NIOSH]
