Investigation of occupational wrist injuries in women.
Terminal Progress Report, 1981 May; :1-15
Occupationally caused carpal tunnel syndrome (CTS) in women was investigated through three studies: test battery development for workplace surveillance of CTS; effects of work pace, wrist splints, light duty work, and time off on CTS; and an anatomic study of the pathomechanics of CTS. The test battery included measures of median and ulnar nerve performance in the hand and wrist. Age was determined to be the most consistent and significant factor of normal subject performance. The test battery was then used to study the effectiveness of common interventions for CTS. Workers from two automobile upholstery factories were used to evaluate the effectiveness of specific changes in work pace and work with and without wrist splints. Results of the pace study tend to support the use of pacing as a control measure for occupational CTS. The use of wrist splints actually served to aggravate CTS. In a longitudinal study, seven of eight subjects demonstrated some improvements in performance corresponding to time off or light duty work; two subjects who worked overtime demonstrated a worsening of performance; and all subjects given splints showed immediate worsening of symptoms. The anatomical study revealed marked mononuclear infiltration in vascular walls of vessels within the carpal tunnel which in similar to a pathological condition found in rheumatoid arthritis.
