Objectives To observe the effect of rehabilitation robots with routine rehabilitation training on walking func -tion after stroke .Methods Sixty patients with stroke were randomly divided into treatment group and control group , 30 ca-ses in each group .The control group received routine rehabilitation training while the treatment group received routine reha -bilitation training by rehabilitation robots .The lower extremity functions ,balance and walking ability were assessed with a simplified Fugl-Meyer Assessment(FMA) and using the Berg Balance Scale (BBS) before treatment and after 12 weeks. Results Before treatment , neither the treatment group nor the control group showed any statistically significant difference in terms of FMA and BBS results (P>0.05).After 12 weeks′training, both groups showed significant improvement in terms of FMA and BBS results(P<0.05).The treatment group showed significantly better improvement in lower extremity function, balance and walking function than the control group (P<0.05).Conclusion Rehabilitation robots can signifi-cantly improve walking function in patients after stroke .
