Objective: To compare the walking ability, mobility, and satisfaction among 24 ambulatory participants with stroke while walking under four conditions: without an ankle support device (ASD), with a plastic ankle-foot orthosis (AFO), and with two types of elastic ASDs— namely, a long ankle sling made from a 3- to 4-inch bandage, and elastic ankle support equipment (EASE) made from elastic bands with buttonholes and rivet buttons. Methods: This crossover design study assessed spatiotemporal gait variables and mobility using the Timed Up and Go test (TUG) while participants walked under the four conditions in random order. They then completed a self-report questionnaire regarding satisfaction with the three ASDs. The findings were compared using the Friedman and Wilcoxon signed rank test. Results: The participants’ spatiotemporal and TUG data improved significantly when walking with a long ankle sling and EASE compared to the other two conditions (p<0.05). Participants satisfied with the dimensions, weight, safety, security, and effectiveness of the long ankle sling and EASE (p<0.001). The EASE was also comfortable and easy to adjust, whereas the AFO was noted for its durability (p<0.01). Conclusion With the design to promote mobility during both the swing and stance phases, the present findings support the clinical benefits of elastic ASDs, specifically a long ankle sling and EASE. The EASE is also user-friendly; thus, it can be applied in various clinical and community settings, particularly in those with limited budget.
