The objectives of this study were 1) to summarize in a clinically meaningful way information on occupational risk factors for carpal tunnel syndrome (CTS), and 2) to test a questionnaire on risk factors that could be used by physicians with their patients. For the two objectives, a systematic literature review was performed and synthetized graphically, and a questionnaire was developed and administered to 238 patients who underwent release surgery for CTS. Patients were classified in four groups according to the incidence rate of CTS surgery in their occupation. Answers to the questionnaire on exposure to risk factors for CTS were compared between these four groups with the hypothesis that the group with the highest incidence would report the heaviest exposure. The results showed that questioning workers on the amount of force required to perform tasks that are “especially demanding” for the wrists or hands is both useful clinically and valid to be used by the clinician to make a judgement on the occupational nature of CTS. Repetitiveness and segmental exposure to vibrations or to cold are potentially useful and will need further validation. There is no evidence at present that posture or motion of the wrists is potentially useful to describe occupational exposure when questioning patients with CTS. Am. J. Ind.
