Abstract
Twelve male subjects participated in an investigation of the biomechanical stresses of symmetric lifting in stooped and kneeling postures. Electromyographic (EMG) data of eight trunk muscles were collected during various lifting tasks. These data were input to a dynamic biomechanical model and used to predict compression and shea forces at the L3 level of the lumbar spine. Results indicated that peak compression and shear forces are significantly affected by posture, height of life, and the amound of weight lifted.
