Thera-Band抗阻肌力训练对脑卒中患者下肢运动功能及步态的影响
The effect of Thera-Band resistance strength training on motor function of lower limbs and gait after stroke

目的 观察Thera-Band渐进抗阻肌力训练对脑卒中后患者下肢运动功能及步态的影响。 方法 将脑卒中后偏瘫患者48例按随机数字表法分为治疗组（24例）和对照组（24例）。对照组采用常规康复治疗，治疗组在常规康复治疗基础上增加Thera-Band弹力带对偏瘫侧肌肉进行渐进抗阻训练。分别于治疗前和治疗8周后（治疗后）采用Fugl-Meyer运动功能评定量表(FMA)、Berg平衡量表(BBS)、功能独立性评定量表（FIM）中的行走和上下楼梯功能检测标准以及GaitWatch步态分析对2组患者进行评定。 结果 治疗后，治疗组的FMA评分［(24.54±2.47)分］、Berg评分［(39.21±2.25)分］、FIM评分［(12.46±1.06)分］、步频［(79.00±8.08)steps/min］、步幅［(59.75±3.31)cm］、步速［(40.29±5.04)cm/s］以及对照组的FMA评分［(20.67±2.65)分］、Berg评分［(28.92±2.90)分］、FIM评分［(11.92±0.97)分］、步频［(69.17±8.11)steps/min］、步幅［(56.38±3.46)cm］、步速［(36.08±4.84)cm/s］与组内治疗前比较，均有显著改善，差异均有统计学意义(P<0.05），且治疗组患者的FMA评分、Berg评分以及GaitWhatch步频、步幅、步速与对照组治疗后比较，差异均有统计学意义（P<0.05）。 结论 Thera-Band弹力带渐进抗阻训练结合常规康复训练可有效地改善脑卒中患者运动和步行能力。
Objective To explore the effect of progressive strength training with TheraBand on lower limb motor function and gait after stroke. Methods Forty-eight hemiplegic stroke survivors were randomly divided into a treatment group and a control group, each of 24. The patients of both groups were provided with the routine rehabilitation training, while the treatment group additionally trained the muscles of the paretic side progressively using Thera-Band elastic belts. Before and after 8 weeks of treatment, both groups were evaluated using the Fugl-Meyer movement assessment (FMA), the Berg balance scale (BBS), and the walking and stair negotiation components of the functional independence measure (FIM). GaitWatch gait analysis was also performed. Results After the treatment, significant improvement was observed with both groups′ average FMA scores, BBS ratings, FIM scores, stride frequency, stride length and walking speed, but the treatment group showed significantly greater improvement than the control group, on average. Conclusion Using Thera-Band elastic belts to provide resistance can supplement routine rehabilitation training in improving motor function and walking ability after a stroke
