Abstract
Background: A plastic non-hinged ankle-foot orthosis (AFO) is a standard ankle support device (ASD) commonly prescribed for individuals with walking impairments in general clinical settings of a developing country. Although it promotes toe clearance during the swing phase, its inherent rigidity can limit ankle rocker during the stance phase, thereby facilitating the development of compensatory strategies that affect walking and mobility in these individuals.
Objectives: To develop an alternative practical ASD assisting movements not only the swing but also the stance phases and compare their effects to a non-hinged AFO and no-ASD conditions on walking and mobility of healthy participants.
Materials and methods: This study developed elastic ASDs from a 3- to 4-inch bandage, called a long ankle sling, and elastic bands with buttonholes, called elastic ankle support equipment (EASE). Their effects and satisfaction were compared with those of no-ASD and non-hinged AFO in 18 healthy participants. Outcomes were measured as spatiotemporal gait variables, mobility using the timed up and go test (TUG), and satisfaction using a self-report questionnaire.
Results: Spatiotemporal and TUG data of the elastic ASD conditions showed no significant differences from the no-ASD condition, but significantly better than those of the AFO condition. The elastic ASDs met the criteria for dimensions, weight, safety, and effectiveness (p<0.001). The EASE was also comfortable and easy to adjust, whereas the AFO was durable (p<0.01).
Conclusion: The present study suggests the potential clinical benefit of elastic ASDs as they did not hinder the walking and mobility of healthy participants, i.e., allowed healthy participants to maintain walking ability and mobility comparable to unassisted walking. Given its ease of adjustment and application, the EASE is a particularly promising and user-friendly ASD for implementation in various clinical and community settings.
