Abstract
The goal of rehabilitation after stroke is to restore safe and sufficient function to hemiplegic patients, and prescription of an ankle-foot orthosis (AFO) to improve speed and functional ambulation is a part of this program. This crossover randomized interventional study aimed to evaluate the effect of an anterior ankle-foot orthosis (AAFO) and posterior leaf-spring ankle-foot orthosis (PLS AFO) on speed and functional ambulation in hemiplegic stroke patients. Clinical assessments were performed on 11 hemiplegic stroke patients by the AAFO, PLS AFO, and wearing shoes. Functional ambulation was measured by the 6-min walking test, Timed Up and Go Test, Time Up and Down Stair Test, and Functional Ambulation Category. Walking speed was measured by the 10-m test. Both PLS AFO and AAFO significantly improved the performance of TUDS and TUG tests in hemiplegic patients. However, by using PLS AFO, walking distance was significantly greater than walking with shoes. There was no significant effect on the walking speed improvement using PLS AFO or AAFO compared to wearing shoes. The positive effects of the AAFO and PLS AFO on functional ambulation were significant. By using PLS AFO, hemiplegic patients could walk a longer distance than wearing shoes.
