BIOMECHANICAL ANALYSIS OF LOADS ON LUMBAR SPINE, KNEE, AND HIP JOINTS DURING MANUAL LIFTING
Keywords: lifting, biomechanical analysis, L5/S1, net forces and moment
AbstractINTRODUCTION: Work-related low-back pain is prevalent in both developed and developing countries. Since this injury often results in considerable discomfort for the employee and a large expense for the employee and employer, there have been many studies on manual lifting. As it is a major health-risk factor in China, research into problems related to manual lifting is of the utmost importance. Therefore, the purpose of this study was to examine the effect of loads on lumbar spine, knee, and hip joints during manual lifting, and to provide a biomechanical basis for establishment of a Chinese Recommended Weight Limit for employees and for employers.
