Abstract:
Objective To observe the effects of early intelligent feedback rehabilitation training system of lower extremities on walking ability in stroke patients with hemiplegia. Methods Forty post-stroke hemiplegic patients (onset <1 month)were enrolled. They were randomly divided into either an intelligent feedback rehabilitation group or a conventional rehabilitation group by the admission numbers (n=20 in each group). The rehabilitation training began at 48 hours after patient′s condition stabled. The conventional rehabilitation group received conventional rehabilitation training only,and on this basis,the patients of intelligent rehabilitation group underwent walking ability training using intellectual feedback rehabilitation training system of lower extremities. The walking ability of lower-extremity of the patients was evaluated with the Fugl-Meyer Assessment Scale (FMA-L)and Holden Walking Classification. The changes of the tension and strength of tibialis anterior muscle and gastrocnemius muscle were evaluated by the surface myoelectric signals. Results Before treatment,there were no significant differences in FMA-L scores and Holden walking function classification between the two groups (P>0. 05). Four weeks after treatment, the FMA-L scores were improved in both the intelligent and conventional rehabilitation groups compared to before treatment (P<0. 01);the differences were 20. 0 ± 6. 2 and 5. 1 ± 1. 6 respectively before and after treatment. The degree of improvement of the intelligent rehabilitation group was better than that of the conventional rehabilitation group (P<0. 01). Holden walking function classification showed that only the intelligent rehabilitation group was improved as compared to before treatment (P<0. 01). Four weeks after treatment ,the strength and tone of the tibialis anterior muscle and gastrocnemius muscle of both groups were increased compared to before treatment (P <0. 01 ). The differences of the strength and tone of the tibialis anterior muscle were 20 +7 and 12 +4μV respectively in the rehabilitation groups before and after treatment,and those were 12+4 and 9+3μV in the conventional rehabilitation group;the differences of the strength and tone of the gastrocnemius muscle of the intelligent rehabilitation group were 25+8 and 19+6μV respectively before and after treatment,and those of the conventional rehabilitation group were 10+3 and 11+2μV respectively. There was significant difference between the intelligent rehabilitation group and the conventional rehabilitation group (P <0. 01 ). Conclusion The treatment of early intelligent feedback rehabilitation training system of the lower extremities may significantly improve the walking ability of the lower extremities in stroke patients with hemiplegia.
