简要总结
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.

结局指标
主要结局
Change from Baseline in Dominant Lower Limb Y-Balance Test Composite Score at 6 Weeks
时间窗: Baseline and 6 weeks
Composite score (%) of the dominant lower limb calculated from the maximal reach distances in the anterior, posteromedial, and posterolateral directions of the Y-Balance Test, normalized to lower limb length using the formula: \[(anterior + posteromedial + posterolateral) / (3 × lower limb length)\] × 100. Higher values indicate better performance on the test.
Change from Baseline in Non Dominant Lower Limb Y-Balance Test Composite Score at 6 Weeks
时间窗: Baseline and 6 weeks
Composite score (%) of the non dominant lower limb calculated from the maximal reach distances in the anterior, posteromedial, and posterolateral directions of the Y-Balance Test, normalized to lower limb length using the formula: \[(anterior + posteromedial + posterolateral) / (3 × lower limb length)\] × 100. Higher values indicate better performance on the test.
