COMPUTERIZED SIMULATION FOR SAGITTAL LIFTING MOTION

摘要

This paper reports on a dynamic simulation model developed for biomechanical analyses ofrnlifting activities performed in the sagittal plane. The model simulates the dynamic motion of liftingrntasks for five body joints: the elbow, shoulder, hip, knee, and ankle. The inputs to the model includerninitial and final joint postures; gender, weight, and height; weight of load; lifting height; and containerrndimensions. The model predicts the kinetics and kinematics for the lift. Actual motion data wererncollected using 10 subjects in the laboratory for 360 lifts which consisting of 12 lifting tasks includingrntwo lifting heights, two container sizes, and three weights of load. Results demonstrate that thernsimulation model can be an effective alternative to collecting posture and time-displacement data forrnlifting task analyses.
