A study was made of the feasibility of complimenting the AMP electric wire terminating machine with a comfortable arm rest to enhance operator comfort and productivity. The results indicate that working with an arm rest is more comfortable than working without one. The fact that the number of errors increases with production time suggests an increase in fatigue. Fatigue induced errors can be prevented by decreasing the amount of hand motions and their magnitudes; this is achieved with 2 of the arm rests described. The mean number of errors is significantly reduced with all 3 arm rest designs described, especially with the hammock arm rest. All arm rest tested resulted in decreased production time and subsequent increase in productivity.
