摘　　要：目的探究踝关节等速肌力测试和平衡功能测试的相关性,为全面评估踝关节状态提供科学依据。方法随机选取150例慢性踝关节不稳患者作为研究对象,第一天进行等速肌力测试,记录在不同角速度下双侧踝关节内翻、外翻、跖屈、背屈的肌力测试结果;休息2天,于第4天进行静态平衡测试(单腿平衡测试、单足跟抬高测试、单腿下蹲测试)和动态平衡测试(单腿跳跃测试、双腿跳跃测试、回避测试)。分析患者双侧踝关节各肌群之间肌力是否存在差异,以及其与动、静态平衡测试的相关性。结果慢性踝关节不稳患者踝关节内翻肌力患侧为(21.5±10.2)N·m,健侧为(25.5±11.2)N·m,患侧明显低于健侧(P<0.05);而健侧与患侧踝关节的外翻、跖屈、背屈肌力无显著差异(P>0.05)。在静态平衡测试中,单腿站立测试与内翻肌力缺陷存在低相关性(r=0.246);单足跟抬高测试与内翻肌力缺陷存在中等程度相关性(r=0.514)。在动态平衡测试中,回避测试与内翻肌力缺陷存在低相关性(r=0.229)。结论在评价慢性踝关节不稳中,等速肌力和平衡功能之间存在一定相关性,且这些平衡功能测试对评价踝关节状况以及等速肌力都具有显著的临床意义。Objective In this study,correlations were performed between ankle isokinetic muscle strength and balance,to help the evaluation of factors relating to chronic ankle instability.Methods One hundred and fifty patients with chronic ankle instability(CAI)were randomly recruited as the study subjects.Isokinetic muscle strength was tested on the first day,and the results of tests examining bilateral varus valgus,metatarsal flexion and dorsiflexion at different angular velocities were collected.After two days of rest,the balance function tests,including static balance tests(oneleg heel elevation test,one-leg squat test)and dynamic balance tests(one-leg jump test,two-leg jump test and avoidance test)were conducted.We explored the difference in muscle strength between the muscle groups of the bilateral ankle joint,and the correlations between muscle strength and the dynamic and static balance tests.Results In patients with chronic ankle instability,the varus muscle strength of the affected side[(21.5±10.2)N·m]was significantly lower than that of the healthy side[(25.5±11.2)N·m;P<0.05].There were no significant differences in valgus,metatarsal flexion or dorsal flexion strength between the healthy side and the affected side(P>0.05).In the static balance test,there was a low correlation between the single leg standing test and varus muscle strength defect(r=0.246).There was a moderate correlation between the single heel elevation test and varus muscle strength defect(r=0.514).In the dynamic balance test,there was a low correlation between the avoidance test and varus muscle strength defect(r=0.229).Conclusion In the evaluation of chronic ankle instability,there is a correlation between isokinetic muscle strength and balance function.The balance function tests bring benefits to the clinical evaluation of ankle condition and isokinetic muscle strength.
