[Gait analysis in hemiplegic patients after gait training or surgery of a foot deformity].

The change of gait in stroke patients after gait training or surgery for foot deformity was analyzed according to walking cycle and gait speed and cadence by means of the accelorometer or the large force plate. The results were summarized as follows. Twenty patients receiving gait training. Variation of the stride duration decreased gradually on both sides. The stance phase and the double support phase had the tendency to demonstrate equal percentage on both sides, decreasing in the unaffected side. The percentage values were higher than those in the normal person except a few cases. The cadence increased in all cases except one. Twenty-two patients following surgery for foot deformities. Walking cycle revealed almost the same result as that of cases receiving gait training. The percentage of the double support phase in the unaffected side characteristically approached that of the affected side after surgery, suggesting surgical benefits. Cadence decreased in 7 cases, while gait speed increased in all cases. It may come from the wider stride length after surgery.
