Abstract: (44 Views)
Background and Objective: Foot drop in hemiplegic stroke survivors often impairs balance and gait; posterior leaf-spring ankle-foot orthoses (AFOs) are designed to mitigate these deficits. This study aimed to examine the immediate effects of a posterior leaf spring AFO on postural balance and gait performance in individuals with post-stroke hemiplegia.
Materials and Methods: In this pre–post quasi-experimental study, 20 individuals with chronic stroke and foot drop (mean age: 58.23 ± 5.23 years) were recruited using convenience sampling based on inclusion and exclusion criteria. The center of pressure displacement and velocity were measured via a force platform during standing, with and without an AFO, under eyes-open and eyes-closed conditions. Functional balance was evaluated using the Timed Up and Go (TUG) test. Data were analyzed using a two-way repeated-measures analysis of variance (α = 0.05).
Results: Wearing the posterior leaf spring AFO resulted in significant improvements in center of pressure displacement and velocity (P < 0.05). Furthermore, the TUG test was significantly reduced when the participants used the orthosis (P = 0.02).
Conclusion: The posterior leaf spring AFO produces immediate improvements in postural balance and gait performance in individuals with post-stroke hemiplegia. This orthotic intervention may serve as an effective rehabilitative tool to enhance safety and quality of life in this population.
