Abstract: Objective To explore the effects of lower limb exoskeleton robot rehabilitation training on lower limb motor function of hemiplegic patients after stroke. Methods A total of 54 patients with stroke hemiplegia within 12 months of onset were randomly divided into the test group(n=27)and control group(n=27). The control group received routine rehabilitation training and walking training, while the test group received routine rehabilitation training combined with lower limb exoskeleton robot rehabilitation training. Walking function was assessed before, 2 weeks and 4 weeks after training. The 6 minute walking test(6MWT), 10 meter walking test(10MWT), functional ambulation category(FAC), and Fugl-Meyer assessment for lower extremity(FMA-LE)were used to assess the lower extremity motor function. Gait analysis was collected by using the motion capture system. Results (1) After 2 and 4 weeks of training, the 6MWT and 10MWT of both groups were significantly improved(P<0.05); after 4 weeks of training, the 6MWT of both groups was further improved compared with that of 2 weeks(P<0.001); the 10MWT of the test group was significantly improved compared with that of 2 weeks(P=0.008 5). (2) After 2 and 4 weeks of training, FAC and FMA-LE in both groups were significantly improved(P<0.01); FMA-LE in the two groups was further improved after 4 weeks of training compared with that of 2 weeks(P<0.001). (3) After 4 weeks of training, the gait cycle of the test group was significantly improved compared with that before training(P=0.003 5)and 2 weeks of training(P=0.003 2). Conclusion The lower limb exoskeleton robot can effectively improve the lower limb motor function, walking function and walking cycle, and its effect is equivalent to that of conventional walking training.
