Abstract

Objective

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.

Methods

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.

Results

No significant differences in peak torques per body weight strength ratios of trunk extensors and flexors between the 2 tested groups (P > .05) were found. Similarly, no significant difference was found in the trunk muscle endurance between the 2 tested groups (P > .05).

Conclusion

No statistically significant differences were observed in the strength and endurance of the trunk muscle between women with CAI and healthy women.

评估躯干肌肉力量和耐力：患有和未患有慢性踝关节不稳的女性的比较

本研究的目的是比较患有慢性踝关节不稳定（CAI）的女性与未患有 CAI 的女性的躯干肌肉力量和耐力。方法将 62 名女性分为两组，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 等动测力计测量躯干伸肌和屈肌每体重的峰值扭矩。麦吉尔核心耐力测试（俯卧桥式、右侧桥式、左侧桥式、躯干屈曲和水平后伸）用于评估躯干肌肉耐力。结果两组受试者的躯干伸肌和屈肌每体重峰值扭矩力量比没有发现显著差异（P > .05）。结论 CAI 女性和健康女性在躯干肌肉的力量和耐力方面没有发现明显的统计学差异。
