Instruct the employees on the importance of neutral wrist position while manipulating material. Employees were observed with apparent high finger pinch grip forces while feeding material through the machine. High pinch grip forces are associated with cumulative trauma disorders. Supply finger coverings to increase the coefficient of friction between the hands and the fabric. Also train employees to use power grips wherever possible.
Employee uses poor sitting posture.
Any adjustments available on the chair do not appear to have been used. Employees were observed to have the chair far back from the work while leaning forward into the work. This leaning posture was accompanied by repeated torso reciprocating flexion as an aid to feed material through the sewing machine. Repeated torso flexion with force is a causative factor in back pain. Use chairs with adjustable lumbar support, adjustable seat height to allow the employee to have both feet on the floor with thighs parallel to the floor without excessive force on the underside of the thighs.
