Investigation of postural sway characteristics of patients after total hip replacement
인공 고관절시술자환자의 중심동요 특성에 관한 연구
Abstract
This research investigates the possibility of using the postural sway of patients as a reference for measruing the progress of the disease and healing of patients who received total hip replacement; the progress of the disease by X-ray pictures, the pain felt by the patients, and the difficulties encountered in moving the joints. The measurements on the force platform were taken during a 25 second period standing on both feet and during a 5 second period standing on one foot with both eyes open. The result of the research showed that the trace and area of the overall length of postural sway was a good indicator which represented the healing progress of the patients who received total hip replacement, and the weakening of the muscles and the recovery process for 3 or 4 month after receiving the operation, which did not appear on X-ray pictures, were exhibited on the postural sway. Finally, standing on a single foot represented the healing progress much better than standing on both feet.
