专业舞蹈演员平衡功能测试及其意义

Performance of Posture Control for Professional Dancers

目的探究专业舞蹈演员在平衡控制方面的特点。方法2017年4月至8月,国际著名剧团专业舞蹈演员21例为实验组,身高、年龄等匹配的医务人员21例为对照组。采用Tetrax Balance系统评估综合姿势稳定性,并行躯干稳定性测试(TST)和星形偏移平衡测试(SEBT)。结果所有被试双侧TST失稳次数和SEBT最远长度无显著性差异(|t|<0.634,P>0.05);实验组TST失稳次数少于对照组(t=-2.667,P<0.05),SEBT最远长度显著少于对照组(t=-3.991,P<0.001),跌倒指数无显著性差异(t=1.810,P>0.05)。结论与医务人员相比,专业舞蹈演员静态平衡功能较优,动态平衡功能较差,综合平衡控制能力无明显优势。

Objective To explore the posture control of professional dancers.Methods From April to August,2017,21 professional dancers from an international famous club were as experimental group.Matching the height and age,etc.,21 medical workers were recruited as control group.They were tested with Tetrax Balance Evaluation System,and assessed with Trunk Stability Test(TST)and the Star Excursion Balance Test(SEBT).Results There was no significant difference on fail-time of TST and maximum distance of SEBT between right and left sides in both groups.The fail-time of TST was less in the experimental group than in the control group(t=-2.667,P<0.05),as well as the maximum distance of SEBT(t=-3.991,P<0.001).There was no significant difference on falling index between both groups(t=1.810,P>0.05).Conclusion Compared with medical workers,professional dancers do better in static balance,but worse in dynamic balance.Their performance of posture control is almost the same as the others.
