Hum Factors 1986 Jun; 28(3):325-336
Procedures were described for analysis, identification of recognized risk factors, and engineering control of occupational repetitive trauma disorders, such as carpal tunnel syndrome and tendonitis, which are a major cause of lost time and workers' compensation in many hand intensive industries. The use of computer aided design programs for workstation design was also discussed. Hypothetical examples were included, which encompass elements of many real situations observed by the authors. Reported risk factors included repetitive and forceful exertions, certain postures, mechanical stress, low temperatures, gloves, and vibration. Risk factors were identified using job analysis procedures based on traditional work methods analysis. The authors conclude that risk factors can be controlled through reallocation of work, balancing of tools, selection of alternative tool designs, work relocation, selection of suitable hand protection, and elimination of hand exposure to low temperatures and vibration. The authors recommend the use of drawing board manikins with computer aided design systems to estimate the best work location for a given task.
