In response to a request from Caldwell Manufacturing Company (SIC- 3442), Williamsport, Maryland, an evaluation was undertaken of carpal tunnel syndrome in assembly department workers. Caldwell Manufacturing employed about 65 hourly workers in the manufacture of window balance systems. A medical evaluation and an ergonomic evaluation were conducted. All of the assembly line jobs appeared to involve risk factors commonly associated with cumulative trauma disorders of the upper extremity: numerous hand/wrist manipulations, in combination with varying degrees of force and deviated wrist positions. At the time of the survey there were five medically confirmed cases of carpal tunnel syndrome and six additional possible cases among the 28 assembly workers. Two tasks were determined to represent the greatest risk: pulling springs to attach them to window liners, and hooking springs. In addition, defective material and pressure to increase production were identified as contributing factors. The authors conclude that a carpal tunnel syndrome hazard existed at the facility. The authors recommend specific measures to minimize the risk of carpal tunnel syndrome.
