| Abstract: | [Purpose] This study compared the muscle activities of the neck and upper-limb musclesbetween able-bodied individuals and persons with paraplegia during wheelchair propulsionon the ground. [Subjects and Methods] The muscle activities of the neck and upper-limbmuscles of 8 normal individuals and 8 individuals with paraplegia were analyzed duringwheelchair propulsion. The activities of the latissimus dorsi, pectoralis major,anterior/posterior deltoids, triceps brachii, extensor carpi radialis, andsternocleidomastoid muscles were assessed. [Results] The paraplegic group showedsignificantly higher sternocleidomastoid activity than the normal group. Latissimus dorsiactivity was also higher in the paraplegia group than in the normal group, but thedifference was not significant. There were no significant differences in the other muscleactivities between groups. [Conclusion] Paraplegic patients tend to use thesternocleidomastoid and latissimus dorsi muscles with greater degrees of activity.Therefore, physiotherapists should not overlook the treatment of these muscles forparaplegic patients who are long-term wheelchair users.Key words: Wheelchair propulsion, Muscle activities, Upper-limb muscle |
