Abstract |
Methods for analyzing continuous physical stress measurements and for evaluating physical stress exposure were developed. Using continuous biomechanical data which was taken directly from electrogoniometers or force sensors, a quantitative exposure assessment strategy for physical stress associated with repetitive manual tasks was developed. Large amounts of data were reduced into a quantifiable metric that accounts for recognized musculoskeletal exposure factors, including repetitiveness, postural or forceful exertion stress, and duration. Wrist posture and work pace were each controlled. The findings of the study showed that frequency weighted filters corresponding to discomfort responses associated with controlled movements at specific frequencies and amplitudes could be developed and applied for measuring exposure to repetitive motion. Field studies were conducted at selected industrial sites and the findings proved that spectral analysis was able to quantify upper limb repetitive motion, posture, and force. |
