Arthritides: Effect of Repetitive Motion on the Musculoskeletal System.
NIOSH 1979 Jun:120-128
The effect of pattern of usage on the structure and function of the hand was studied in a group of female worsted mill employees. The employees had engaged in the highly repetitive, stereotyped tasks of burling, winding, and spinning for at least 20 years. Data were obtained from clinical measurements of active ranges of motion, measurements of distal and proximal interphalangeal circumferences, and radiographs. Range of motion, malalignment, radiographic degenerative joint disease score, and derivatized circumference data were collected. Differences existed between the right and left hands, and most task related impairments were in the right hand. All three tasks were differentiated by patterns of usage of the women's hands. Guidelines for further testing of diseases associated with stereotyped, repetitive tasks are proposed by the author.
