The purpose of this study was to compare the strength and endurance of the trunk muscles in women with chronic ankle instability (CAI) compared with those who do not have CAI.
Sixty-two women were assigned into 2 equal groups of 31; group A included women with CAI and group B included healthy women. Peak torques per body weight of the trunk extensors and flexors were measured using a Biodex System 3 Isokinetic Dynamometer. McGill core endurance tests (prone bridge, right side bridge, left side bridge, trunk flexion, and horizontal back extension) were administered to assess trunk muscle endurance. Statistical analysis using 1-way between-subjects multivariate analysis of variance was performed.
No significant differences in peak torques per body weight strength ratios of trunk extensors and flexors between the 2 tested groups ( > .05) were found. Similarly, no significant difference was found in the trunk muscle endurance between the 2 tested groups ( > .05).
No statistically significant differences were observed in the strength and endurance of the trunk muscle between women with CAI and healthy women.
本研究的目的是比较慢性踝关节不稳（CAI）女性与无CAI女性的躯干肌肉力量和耐力。
62名女性被平均分为两组，每组31人；A组包括患有CAI的女性，B组包括健康女性。使用Biodex System 3等速测力计测量躯干伸肌和屈肌每体重的峰值扭矩。进行麦吉尔核心耐力测试（俯卧桥、右侧桥、左侧桥、躯干屈曲和水平背部伸展）以评估躯干肌肉耐力。采用单因素组间多变量方差分析进行统计分析。
在两个测试组之间，未发现躯干伸肌和屈肌每体重力量比的峰值扭矩有显著差异（>0.05）。同样，在两个测试组之间，躯干肌肉耐力也未发现显著差异（>0.05）。
在患有CAI的女性和健康女性之间，未观察到躯干肌肉力量和耐力有统计学上的显著差异。
