Upper limb musculoskeletal disorders in highly repetitive industries: precise anatomical physical findings

Article Abstract:

Fifty-four percent of 146 female workers in highly repetitive jobs were found to have musculoskeletal disorders in the upper limb that were potentially work related. Many workers had multiple problems. 33 percent of the workers were affected bilaterally. 31 percent had muscle pain and tenderness in the neck shoulder area, whereas 23 percent had such a pain in the forearm hand musculature. 16 people were affected by carpal tunnel syndrome, the most common form of neuritis. DeQuervain's tenosynovitis and wrist flexor tendinitis were the most common found tendon disorders.

Quantifying repetitive hand activity for epidemiological research on musculoskeletal disorders - Part II: Comparison of different methods of measuring force level and repetitiveness

Article Abstract:

An attempt is made to compare the different methods of assessing repetitive hand activities, on 733 subjects. Results showed that different definitions of repetitive exertion might lead to measuring different physical exposure phenomena and produce very different results, and there were poor correlations between the measures of repetitiveness as well as between force quantifications estimated by the different methods.
