Objective To explore the the MOTOmed right to improve lower extremity motor function in patients with hemiplegia in order to determine the significance of their clinical treatment. Methods 20 patients of the treatment group targeted MOTOmed lower extremity training （2 times / day, 30 minutes / time） and conventional PT training in the control group conventional PT training. One month after treatment using a modified Ashworth scale evaluation; Fugl-Meyer Assessment Law; walk functional classification and maximum walking speed assessment. Results The patients treated with lower limb muscle tension and walking speed than the control group also improved significantly （P〈0.01）; Fugl-Meyer lower limb motor function score treatment group （x± s） in the control group was （25.35± 7.52）, （20.53 ± 3.45）, Fugl-Meyer balance score treatment group was （10.43 ±2.99）, after treatment is （8.98 ±3.18）; statistical analysis, there existed significant difference （P〈0.01）. Conclusion The patients with hemiplegia relevance the MOTOmed of lower limb training plus conventional PT training, can improve lower extremity flexibility, relieve spasm; contribute to the significant improvement of lower limb movement, balance function, the promotion of walking ability.
