Some employers have developed ergonomic programs to help workers adjust their pace of work and arrange office equipment to minimize problems. In oscillatory motion, an object tends to repeat certain movements in the same pattern repeatedly until it is acted upon by some external force. The energy of a swing decreases with every oscillation because the energy given to the swing is utilized to do the work to complete one oscillation every time. Physical ergonomics is concerned with the impact of anatomy, anthropometry, biomechanics, physiology, and the physical environment on physical activity. Ann Rehabil Med.
