下肢生物反馈训练对脑卒中患者运动及平衡功能的影响

Effects of lower limb biofeedback training on motor and balance function of stroke patients

目的:观察下肢生物反馈训练对脑卒中患者运动及平衡功能的影响。方法:选取脑卒中患者40例,按随机数字表法随机分为对照组(20例)和治疗组(20例)。对照组接受常规物理治疗;治疗组在常规物理治疗基础上接受下肢反馈训练。两组患者均接受8周治疗。比较两组患者治疗前后的下肢运动功能评分(Fugl-Meyer评价量表,FMA-L)、平衡功能评分(Berg平衡量表,BBS)、日常生活活动能力(改良Barthel指数,BI)以及下肢肌力(徒手肌力评估,MMT)的变化。结果:两组患者治疗前各项指标差异均无显著性意义(P>0.05),经过8周康复训练后,治疗组FMA-L、MMT、BBS、BI分别由治疗前(20.75 5.37)、(8.70 2.43)、(14.70 6.89)、(16.60 4.10)提高至(31.05 3.32)、(41.20 5.33)、(15.65 1.84)、(32.00 6.39);对照组上述指标分别由治疗前(20.80 4.92)、(15.05 6.75)、(9.60 2.74)、(15.603.46)提高至(28.10 4.28)、(35.30 9.52)、(14.05 2.42)、(28.05 5.33);两组治疗前后的各项功能指标变化差异均有显著性意义(P<0.05)。组间比较,治疗组各项指标明显优于对照组(P<0.05)。结论:通过下肢生物反馈训练提高患者下肢本体感觉有助于脑卒中偏瘫患者运动及平衡功能的恢复,从而明显提高患者日常生活活动能力,值得临床应用及推广。

Objective： To observe effects of lower limb biofeedback training on motor and balance function of stroke patients. Method： Forty patients with stroke were recruited and assigned randomly into two groups： control group （n= 20） and treatment group （n=20）. The control group was treated with conventional physical therapy. Based on conventional rehabilitation, the treatment group was given proprioception training by lower limb biofeedback training. The treatment for both groups lasted for 8 weeks. Changes of lower extremity motor ftmction （FuglMeyer score evaluation scale, FMA-L）, balance function （Berg balance scale, BBS）, Activities of Daily Living （modified Barthel index, BI） and muscle strength of lower limb （manual muscle testing, MMT） in two groups were compared. Result： All indicators had no statistical significance between two groups before treatment （P〉 0.05）. After 8- week treatment, the results of FMA-L （20.75 5.37）, MMT （8.70 2.43）, BBS （14.70 6.89） and BI （16.60 4.10） in treatment group increased to （31.05 3.32）, （41.20 5.33）, （15.65 1.84） and （32.00 6.39） respectively. By contrast, the data of FMA-L （20.80 4.92）, MMT （15.05 6.75）, BBS （9.60 2.74） and BI （15.60 3.46） in control group changed into （28.10 4.28）, （35.30 9.52）, （14.05 2.42）, （28.05 5.33） respectively. Taking all functional parameters into comparison, changes were significant （P〈 0.05） between pre-treatment and post-treatment in both groups. Moreover, the functional parameters of treatment group were improved more significantly than those of control group （P 〈 0.05）. Conclusion： The proprioception training via lower limb biofeedback has positive effect on improving motor and balance function of stroke patients clinically.
