Abstract: Objective To explore the effect of upper limb rehabilitation robot-assisted rehabilitation training on upper limb motor function in patients with subacute hemiplegia after stroke. 
Methods A total of 76 patients with subacute hemiplegia after stroke who were admitted to the hospital were selected and divided into research group (n=38) and control group (n=38) according to the random number table method. The two groups were treated with rehabilitation training, and the research group was additionally given upper limb rehabilitation robot-assisted therapy. Both groups received intervention for 3 weeks. Fugl-Meyer Motor Function Scale score, functional independence score, Brotez hand function score and activity of daily living (ADL) score were compared between two groups. 
Results After treatment, Fugl-Meyer Motor Function Scale score, functional independence score, Brotez hand function score and ADL score in both groups were higher than those before treatment, and higher in the research group (28.73±4.88, 84.32±15.27, 27.28±4.83, 81.47±12.81), respectively than in the control group (24.62±4.35, 76.15±13.44, 23.54±4.19, 73.58±12.25) (P＜0.05). 
Conclusion The upper limb rehabilitation robot-assisted training can improve recovery of motor function of the upper limbs and the quality of life.
