Distinct Directional Postural Stability Deficits Across Lower Limb Musculoskeletal Disorders

Lateral ankle sprain (LAS) and patellofemoral pain syndrome (PFPS) are common musculoskeletal conditions associated with postural instability. However, the direction-specific nature of balance deficits and comparative patterns across these conditions remain unclear. Therefore, the aim of this study is to compare overall, mediolateral, and anteroposterior postural stability indices among individuals with LAS, PFPS, and healthy controls using the Biodex Balance System
