Loads should be lifted and carried as close to the body as possible. Weights carried primarily on one shoulder or one hip should be periodically redistributed or a backpack or other method can be used. Activities involving prolonged static positions of the head, particularly rotation, lateral flexion or extension, must be avoided. Flexion more than 10-15 degrees should also be avoided if it is to be prolonged. Working in a seated position with elbows unsupported should be avoided as it places significant strain on trapezius, scalene, and other frequently injured muscle groups.
Seated posture is very important.
Patients should sit straight up and the chair should support their backs. The arms should be supported at 90 degrees, as should the thighs. The feet should be flat on the floor. The upholstery should be porous to allow heat dissipation. Swivel chairs on casters are preferable.
