Title Trunk posture and back pain: Identification and control of occupational risk factors
Bibliographic information Mar. 1988, Vol.3, No.3, p.87-92. Illus. 21 ref.
Abstract A computer-aided system was developed to evaluate trunk posture during work by measuring the time spent in neutral and non-neutral postures. This system was used to assess postural risk factors in a case-referent study of back disorders in an automobile assembly plant. The use of non-neutral trunk postures, such as forward flexion, lateral bending, and axial twisting, was associated with reports of back pain. The results of this study suggest that job redesign and/or other methods for controlling non-neutral posture be implemented to reduce the risk of back pain on industrial jobs. A general approach to work station design, based on a mechanical model of the human skeletal system, is described. This model is used to develop specific job-design guidelines to prevent awkward trunk posture.
