BACKGROUND: Individuals with @entity130 demonstrate increased sway during quiet stance. The prospective association between balance and disease onset is unknown. Improved understanding of balance in the period between joint @entity66 onset could inform secondary prevention strategies to prevent or delay the disease. This study examines the association between youth sport-related @entity3331 and balance, 3-10years post-injury. METHODS: @entity1 included 50 individuals (ages 15-26years) with a sport-related @entity3331 sustained 3-10years previously and 50 uninjured age-, sex- and sport-matched controls. Force-plate measures during single-limb stance (center-of-pressure 95% @entity7085 -area, path length, excursion, entropic half-life) and field-based balance scores (triple single-leg hop, star-excursion, unipedal dynamic balance) were collected. Descriptive statistics (mean within-pair difference; 95% confidence intervals) were used to compare groups. Linear regression (adjusted for injury history) was used to assess the relationship between @entity7085 -area and field-based scores. FINDINGS: Injured @entity1 on average demonstrated greater medio-lateral excursion [mean within-pair difference (95% confidence interval); 2.8mm (1.0, 4.5)], more regular medio-lateral position [10ms (2, 18)], and shorter triple single-leg hop distances [-30.9% (-8.1, -53.7)] than controls, while no between group differences existed for the remaining outcomes. After taking into consideration injury history, triple single leg hop scores demonstrated a linear association with @entity7085 area (b=0.52, 95% confidence interval 0.01, 1.01). INTERPRETATION: On average the injured @entity1 adjusted their position less frequently and demonstrated a larger magnitude of movement during single-limb stance compared to controls. These findings support the evaluation of balance outcomes in the period between @entity3331 and @entity130 onset.

The impact of previous XXXX on force plate and field-based measures of balance.
