Twelve subjects sorted mail to discover if the mail sorting task or station design caused repetitive strain injury symptoms. Subjects performed the task at six different stations. Each station had two design components for study. Electrodes were placed on the deltoid, trapezius and infraspinatus muscles to study localised muscle fatigue, which is known to be a contributing factor to repetitive strain injuries. 54% of the male and 33% of the female trials resulted in statistical indications of muscle fatigue. There was no indication that the occurrence of indicators was due to station design. Additional analysis was performed using subjective responses of the perceived exertion. There were gender differences but no differences due to station design. The results indicate that the sorting task itself may be responsible for the occurrence of RSI symptoms. To eliminate RSI incidence, it would be necessary to redesign the task and equipment used.Dept. of Industrial and Manufacturing Systems Engineering.
