Train them to allow the machine to do the work eliminating stress on their wrists and hands. Instruct the employees on the importance of neutral wrist position while manipulating material. The employee has left wrist flexion while inserting hem into machine. A possible control for this is rotation of the sewing machine so that the employee feeds the material from right to left rather than from front to back. This would eliminate poor wrist posture while sewing.
Employees stack pants too high on the buggies requiring reaches above shoulder height.
Do not pile pants higher than shoulder high. Buggies should be height adjustable as indicated above. As some employees feed the hems into the machine, the wrist is supinated with finger force to shape the fabric for insertion into the machine. This action may be associated with cumulative trauma disorders. Train employees to fold the fabric before insertion to eliminate the supination with force.
