The purpose of this research is to investigate the load of back muscles in driving the wheelchairs. Two types of wheelchairs were used in this research. One of them was a usual self-propelled wheelchair, other one was a new type with lever devices. These studies were performed on 10 healthy young subjects, who had normal neurological history. Electromyography (EMG) recording was carried out in 8 muscles (trapezius, upper and lower portion of deltoid, latissimus dorsi, triceps brachii, common digital extensor, brachioradialis, flexor digitorum profundus) during driving the wheelchairs. As a result, the EMG data indicated that the load of back muscles was lower during driving the new type of wheelchair than usual one. Additionally, these studies were performed on 4 spinal cord injury victims. However the results of them did not indicate similar trends to healthy subjects.
