Y-Balance Test Training for Ankle Function and Lower Limb Functional Performance

This randomized controlled study investigated whether a 6-week home-based training program based on the Y-Balance Test could improve ankle function and lower limb functional performance in university students. The Y-Balance Test is a functional task that involves standing on one leg while reaching in different directions with the other leg, and it is commonly used to assess dynamic balance and postural control. Participants were randomly assigned to either an experimental group, which performed the Y-Balance Test-based training program, or a control group, which maintained its usual routine without intervention. All participants were assessed at baseline and after 6 weeks. The study assessed Y-Balance Test performance, weight-bearing ankle dorsiflexion, ankle maximal isometric strength, and self-reported ankle function. These outcomes were selected because they are relevant components of ankle function and lower limb performance. The main goal of the study was to determine whether this structured training program led to greater improvements in Y-Balance Test composite score than no intervention. Secondary aims included assessing changes in normalized reach distances, ankle dorsiflexion, ankle strength, and self-reported ankle function. The study did not directly assess injury incidence, but focused on functional measures commonly used in the assessment of factors related to lower limb injury risk.
