任务导向性平衡训练对踝关节扭伤患者平衡功能障碍的影响

Effects of task-oriented balance training on balance dysfunction in patients with ankle sprain

目的:探究任务导向性训练对踝关节扭伤患者平衡功能障碍的疗效。方法:将符合入选标准的40例踝关节扭伤受试者按随机数字表法分为试验组(A组)、对照组(B组),每组20例。在两组均给予常规训练基础上,A组进行任务导向性平衡训练,B组进行平衡板训练。两组受试者在持续4周训练前后进行静态平衡功能[LOS:最大移动距离(MXE)、移动速度(MVL)、反应时间(RT)]和动态平衡(Y-balance)和坎伯拉量表(Cumberland ankle instability tool,CAIT)评估。结果:治疗前,两组受试者肢体各项评分比较差异均无显著性差异(P>0.05)。训练4周后,组内前后比较:(1)LOS评估:A组平衡功能MXE、MVL、RT评分较治疗前均有显著性改善(P<0.05);但B组评分较治疗前无显著性差异(P>0.05);(2)Y-Balance评估:A组与B组治疗后评分均较治疗前改善,且均有显著性差异(P<0.05);(3)坎伯拉量表评估:A组评分较治疗前改善(P<0.05),B组评分较治疗前改善但无显著性差异(P>0.05)。组间比较:Y-balance前后变化值和坎伯拉量表评分A组均优于B组(PP<0.05);LOS评分A组与B组比较无显著性差异(P>0.05)。结论:任务导向性训练可改善踝关节扭伤后患者的平衡功能障碍及运动功能。

Objective:To explore the effect of task-oriented training on balance dysfunction in patients with ankle sprain.Method:Forty subjects with ankle sprain were divided into experimental group(group A)and control group(group B)according to the random number table method,with 20 cases in each group.On the basis of routine training in both groups,group A was given task-oriented balance training,and group B was given balance board training.Two groups of subjects performed static balance function[LOS:maximum excursion(MXE),movement velocity(MVL),reaction time(RT)],dynamic balance(Y-Balance)and Cumberland Ankle Instability Tool(CAIT)assessment before and after training for 4 weeks.Result:Before treatment,there was no significant difference in the scores of limbs between the two groups(P>0.05).After 4 weeks of training,the balance function MXE,MVL and RT scores of group A were significantly improved compared with those before treatment(P<0.05);but there was no significant difference in the scores of group B(P>0.05).The Y-balance scores of group A and group B after treatment were improved compared with those before treatment,and the difference was statistically significant(P<0.05).The CAIT scores of group A were improved compared with those before treatment(P<0.05),and those of group B were improved but had no significant difference(P>0.05).The changes in Y-balance and CAIT scores of group A were better than those in group B(P<0.05);there was no significant difference in the changes of LOS score between group A and group B(P>0.05).Conclusion:Task-oriented training can improve the balance dysfunction and motor function of patients with ankle sprain.
