BACKGROUND
While decreased hip abductor strength, functional performance, and self-reported instability scores have all been shown in association with CAI, any sex difference in the relationship between these indicators is unclear. This study was to determine whether sex differences are present in the relationship between these indicators in individuals with CAI.
METHODS
Thirty-two women and twenty-nine men with unilateral CAI took part. Hip abductor strength and functional performance were respectively assessed using a hand-held dynamometer and the figure-8-hop test. All 61 participants scored the Cumberland Ankle Instability Tool (CAIT) for self-reported ankle instability. Independent sample t-tests and correlation analysis were conducted.
RESULTS
Normalized hip abductor strength and functional performance measures for females were lower than for males. The self-reported ankle instability CAIT score, where higher values represent less instability, was significantly and positively correlated with both normalized hip abductor strength (p = 0.003) and functional performance (p = 0.001) on the affected side in females, but not in males (p = 0.361 and p = 0.192 respectively).
CONCLUSIONS
Sex differences were observed in that there were significant relationships between normalized hip abductor strength, functional performance, and CAIT scores in female CAI participants, but not males, suggesting that CAI evaluation and rehabilitation strategies should be sex-specific.
HIGHLIGHTS
In females with CAI, hip abductor strength and functional performance showed significant relationships with self-reported instability scores. Correspondingly, in clinical practice with individuals with CAI, evaluation criteria may be formulated according to these observed sex differences. Sex differences should be factored into the evaluation and treatment of CAI individuals. Hip strength assessment should be employed with CAI individuals. Hip strengthening and functional hopping may be recommended for the rehabilitation of CAI, especially in female patients.
背景
虽然髋外展肌力量下降、功能表现和自我报告的不稳定性评分均与 CAI 相关，但这些指标之间的关系是否存在性别差异尚不清楚。本研究旨在确定 CAI 患者这些指标之间的关系是否存在性别差异。
方法
32 名女性和 29 名男性单侧 CAI 患者参与了本研究。使用手持测力计和 8 字跳测试分别评估髋外展肌力量和功能表现。所有 61 名参与者使用 Cumberland 踝关节不稳定性工具 (CAIT) 对自我报告的踝关节不稳定性进行评分。进行了独立样本 t 检验和相关性分析。
结果
女性的正常化髋外展肌力量和功能表现测量值均低于男性。自我报告的踝关节不稳定性 CAIT 评分，分数越高代表不稳定性越低，在女性中，受影响侧的 CAIT 评分与正常化髋外展肌力量（p=0.003）和功能表现（p=0.001）呈显著正相关，但在男性中则无相关性（分别为 p=0.361 和 p=0.192）。
结论
存在性别差异，在女性 CAI 患者中，正常化髋外展肌力量、功能表现与 CAIT 评分之间存在显著关系，但在男性中则无此关系，这表明 CAI 的评估和康复策略应具有性别特异性。
重点
在患有 CAI 的女性中，髋外展肌力量和功能表现与自我报告的不稳定性评分呈显著相关。相应地，在 CAI 患者的临床实践中，可以根据这些观察到的性别差异制定评估标准。在评估和治疗 CAI 患者时应考虑性别差异。应在 CAI 患者中进行髋关节力量评估。对于 CAI 的康复，尤其是女性患者，可推荐进行髋关节强化和功能性跳跃练习。
