基于反重力跑台训练系统的双重运动任务训练对脑卒中患者平衡功能的效果

Effects of Dual-task Motor Training with Anti-gravity Treadmill on Motor and Balance after Stroke

目的观察采用反重力跑台训练系统进行双重运动任务训练对脑卒中患者运动及平衡功能的影响。方法 2016年1月至2017年6月,脑卒中偏瘫患者30例随机为对照组(n=15)和试验组(n=15)。两组均接受常规物理治疗,对照组进行反重力跑台步行训练,试验组利用反重力跑台训练系统进行双重运动任务训练,共4周。训练前后采用平衡功能检测训练系统评定平衡功能,同时采用Fugl-Meyer评定量表下肢部分(FMA-L)、Berg平衡量表(BBS)和改良Barthel指数(MBI)进行评定。结果训练后,试验组X方向最大动摇径(Rx)、Y方向最大动摇径(Ry)和包络面积(RecArea)均显著下降(t>4.719, P <0.001),对照组RecArea显著下降(t=5.069, P <0.001),试验组Ry和RecArea低于对照组(t>2.288, P <0.05)。治疗后,两组FMA-L、BBS和MBI评分均显著改善(t> 7.316, P <0.001),试验组优于对照组(t> 2.322, P <0.05)。结论双重运动任务训练有助于脑卒中偏瘫患者运动及平衡功能恢复,提高日常生活活动能力。

Methods From January,2016 to June,2017,30 patients with stroke were assigned randomly into control group(n=15)and treatment group(n=15).Both groups accepted routine physical therapy,the control group accepted anti-gravity treadmill training,while the treatment group accepted dual-task training with anti-gravity treadmill,for four weeks.They were measured with balance training and evaluation system,and assessed with Fugl-Meyer Assessment-lower extremity(FMA-L),Berg Balance Scale(BBS)and modified Barthel Index(MBI),before and after treatment.Results The range of swaying on X axial(Rx)and Y axial(Ry),as well as rectangle area(RecArea)decreased after treatment in the treatment group(t>4.719,P<0.001),while RecArea decreased in the control group(t=5.069,P<0.001).Ry and RecArea were less in the treatment group than in the control group(t>2.288,P<0.05).The scores of FMA-L,BBS and MBI improved after treatment in both groups(t>7.316,P<0.001),and improved more in the treatment group than in the control group(t>2.322,P<0.05).Conclusion The dual-task training via anti-gravity treadmill may improve motor and balance function in stroke patients,and promote the activities of daily living.
