Objective To explore the effect of leg rehabilitation robot training on motor and activities of daily living in hemiplegic pa-tients after stroke. Methods From June, 2015 to July, 2016, 40 hemiplegic patients were randomly divided into control group (n=20) and ex-perimental group (n=20). Both groups received routine rehabilitation, and the experimental group received leg rehabilitation robot training in addition for six weeks. The Fugl-Meyer Assessment-Lower Limb (FMA-L), the Fugl-Meyer Assessment-Balance (FMA-B), Holden walk-ing function classification and modified Barthel Index (MBI) were used to access the motor function, balance function, walking ability and activities of daily living (ADL), respectively. Results After treatment, the scores of FMA-L, FMA-B, Holden walking function classification and MBI improved (χ2>8.980, t>3.902, P<0.01), and were higher in the experimental group than in the control group (χ2=7.632, t>2.075, P<0.05). Conclusion Leg rehabilitation robot could facilitate to improve lower extremity motor function, balance function, walking ability and ADL in hemiplegic patients after stroke.
