Patellar tendinopathy is a common condition resulting in persistent pain, frequently reported during physical activity. The relationship between dynamic postural stability and pain in these individuals is unclear and how it may affect postural stability.
Is there a relationship between acute pain and dynamic postural stability indices in individuals with patellar tendinopathy?
Twenty-two recreationally active individuals with patellar tendinopathy participated. Participants performed a two-legged jump and landed on a single test-limb on a force platform. They completed 100 mm visual analogue scales (VAS) before and after landing trials. Anterior-posterior (APSI), medial-lateral (MLSI), vertical (VSI), and composite (DPSI) stability indices were calculated from ground reaction force data. The relationship between stability indices and VAS for pain as well as pain change scores were assessed via non-parametric Spearman's rho (ρ) rank correlations (p≤.05).
Baseline pain was not significantly correlated with any stability indices. Post-landing pain was significantly correlated with MLSI (ρ = 0.540, p = 0.004) while, VSI (ρ = 0.353, p = 0.053) and DPSI (ρ = 0.347, p = 0.057) had moderate, yet insignificant correlations. Pain change scores demonstrated a large correlation with MLSI (ρ = 0.598, p = 0.002).
As pain increased in individuals with patellar tendinopathy, dynamic postural stability indices values increased, indicating more difficulty transitioning from a dynamic to static state. Although balance deficits are not typically associated with patellar tendinopathy, it appears pain and dynamic postural stability may be related in these individuals.
髌腱病是一种常见病症，会导致持续性疼痛，在体育活动中经常出现。这些个体的动态姿势稳定性与疼痛之间的关系尚不清楚，以及疼痛如何影响姿势稳定性也不明确。
髌腱病患者的急性疼痛与动态姿势稳定性指标之间是否存在关联？
22名有髌腱病的休闲活跃个体参与研究。参与者进行双腿跳跃并单腿落在测力平台上。他们在着陆试验前后完成100毫米视觉模拟量表（VAS）。根据地面反作用力数据计算前后（APSI）、内外侧（MLSI）、垂直（VSI）和综合（DPSI）稳定性指标。通过非参数斯皮尔曼等级相关系数（ρ）评估稳定性指标与疼痛VAS以及疼痛变化分数之间的关系（p≤0.05）。
基线疼痛与任何稳定性指标均无显著相关性。着陆后疼痛与MLSI显著相关（ρ = 0.540，p = 0.004），而VSI（ρ = 0.353，p = 0.053）和DPSI（ρ = 0.347，p = 0.057）有中等程度但不显著的相关性。疼痛变化分数与MLSI有较大相关性（ρ = 0.598，p = 0.002）。
随着髌腱病患者疼痛加剧，动态姿势稳定性指标值增加，表明从动态状态转变为静态状态更加困难。尽管平衡缺陷通常与髌腱病无关，但在这些个体中，疼痛与动态姿势稳定性似乎可能相关。
