Abstract
Gait analysis was performed using a large-sized force plate in 15 patients with osteoarthrosis of the hip joint. All patients were in the advanced-end stage of coxarthrosis.
Weighting-off effect, deceleration phase, acceleration phase, maximum deceleration force, maximum acceleration force, single stance phase, step length and walking speed were measured.
Weighting-off effects on the un-affected side were larger than the affected side in nine patients (Group A). Weighting-off effects of the affected side were larger than the un-affected side in four patients (Group B). There were no weighting-off effects on both sides in two patients (Group C).
In Group A, deceleration and acceleration force of affected side were larger than the un-affected side. On the other hand, in Group B, acceleration force of the affected side was larger than the un-affected side, but the deceleration force of the un-affected side was larger than the affected side. In Group B, step length of the affected side was longer than that of the un-affected side.
