| Objective: To evaluate the effect of functional electrical stimulation (FES) based on normal walking pattern on lower extremity spasm and function in stroke patients by surface electromyography. Methods: A total of 54 eligible stroke patients were randomly divided into FES group and consolation stimulus group (control group). Both groups were given routine clinical and rehabilitation treatment. FES group was intervened by FES, and the control group was given FES without current input treatment. Before and after 4 weeks of treatment, the quadriceps femoris and triceps femoris of lower limbs were tested by sEMG, RMS and iEMG of each muscle were collected, and the patients were evaluated by the MAS and FMA of lower limbs and 10-m walking speed. Results: Before treatment, there was no significant difference between the two groups (P>0.05). After 4 weeks of treatment, MAS, RMS and iEMG of quadriceps femoris and triceps crus in the two groups were lower than those before treatment (P<0.05), and FMA score of lower limbs and 10-m walking speed significantly increased as compared with those before treatment (P<0.05). The improvement of scores in FES group was more satisfactory than that in the consolation stimulus group (P<0.05). Conclusion: FES based on normal walking pattern can effectively reduce the muscle tension of quadriceps femoris and triceps femoris in stroke patients, improve the spasm mode of extensor femoris in hemiplegia patients, and improve the motor function and walking ability of lower limbs, which is worthy of clinical application. |
