Title A comparison of peak vs. cumulative physical work exposure risk factors for the reporting of low back pain in the automotive industry
Bibliographic information Dec. 1998, Vol.13, No.8, p.561-573. Illus. 30 ref.
Abstract Physical exposures to peak and cumulative lumbar spine moment, compression and shear forces, trunk kinematics and forces on hands were analysed in 104 workers who had reported low back pain (cases) and in 130 randomly selected controls. Cases showed significantly higher loading on all biomechanical variables. Four independent risk factors were identified: integrated lumbar moment (over a shift), 'usual' hand force, peak shear force at the level of L4/L5 and peak trunk velocity. Cumulative biomechanical variables are important risk factors in the reporting of low back pain. Spinal tissue loading estimates from a biomechanical model provide information not included in the trunk kinematics and hand force inputs to the model alone. Workers in the top 25% of loading exposure on all risk factors are at about six times the risk of reporting low back pain when compared with those in the bottom 25%. Topics: assembly-line work; backache; body mechanics; case-control study; lumbar column; measurement of physical workload; motor vehicle industry; physical workload; spinal column; work posture.
