早期应用下肢康复机器人对偏瘫患者步行能力的影响

1．统计研究设计：应交代统计研究设计的名称和主要做法。如调查设计（分为前瞻性、回顾性或横断面调查研究）；实验设计（应交代具体的设计类型，如自身配对设计、成组设计、交叉设计、析因设计、正交设计等）；临床试验设计（应交代属于第几期临床试验，采用了何种盲法措施等）。主要做法应围绕4个基本原则（随机、对照、重复、均衡）概要说明，尤其要交代如何控制重要非试验因素的干扰和影响。

Effect of early application of lower limb rehabilitation robot on walking ability of patients with hemiplegia

Objective:To study the effect of walking training with lower limb rehabilitation robot on walking ability of patients with early hemiplegia.Methods:Forty-six hemiplegic stroke patients were randomized into observation group and control group (n=23 each group).Both groups were given conventional rehabilitation treatment,and observation group received walking training with lower limb rehabilitation robot additionally.Functional ambulation category (FAC),affected limb Fugl meyer assess (FMA) and Berg balance scale (BBS) were applied before and after the training.Results:After treatment for 8 weeks,the independent walking rate,BBS score and FMA lower limb score in both groups were increased significantly as compared with those before treatment (P<0.01,0.05),and those in observation group were higher than in control group (P<0.05).Conclusion:The early walking training with lower limb rehabilitation robot can improve the walking ability of patients with hemiplegia.
