This paper explores the measurement of wrist posture and motion on workers in two jobs at a plant that stamps sheet metal parts to be used in automobile assembly. It was hypothesized that the welding assemblers would have more wrist motion than the large press operators, who performed primarily manual material handling activities. Wrist posture was ascertained using a biaxial flexible wire electrogoniometer. Numerical differentiation was performed to calculate angular velocity and acceleration from the posture data. No significant differences were found for the wrist posture or motion data between the jobs.
