Immediate Effect of Foot Drop Stimulator in Outpatients with Chronic Stroke: A Mixed Method Study

Background: The foot drop stimulator is designed to improve the walking ability of foot drop in patients after stroke, however, studies on clinical effects are still lacking.Objective: To investigate the effect of a foot drop stimulator on the walking and balancing abilities of foot drop patients after a stroke.Design: One-Group (Pretest-Posttest) Design.Methods: All subjects walked in all three conditions: foot drop stimulator (FDS) ankle foot orthosis (AFO) and barefoot. Primary outcome measures were assessed for walking and balance using a 10-m walking test (10MWT) and a timed up and go test (TUG). Secondary outcome measures consisted of a brief user interview, and the patients recorded the advantages and disadvantages of each condition.Results: FDS, AFO, and barefoot conditions showed a statistically significant difference in 10MWT and TUG (P .05).Conclusion: In this study, the foot drop stimulator contributed to improving the balance ability, and the walking ability was similar to the effect of the anklefoot orthosis.
