To explore the efficacy of functional electrical stimulation (FES)-assisted rehabilitation cycling on the functional recovery of lower limbs in patients with hemiplegic stroke and the assessment value of surface electromyography (sEMG).
A total of 66 patients with stroke accompanied by hemiplegia of the lower limbs were enrolled in the present prospective study and randomly divided into the experimental group and control group, with 33 patients in each group. FES-assisted rehabilitation cycling was applied in the experimental group, while only rehabilitation cycling was performed without setting the stimulation parameters in the control group. sEMG and the Fugl-Meyer assessment (FMA) were carried out, and the modified Barthel index (MBI) of the lower limbs was assessed before treatment and after 4 weeks and 8 weeks of treatment.
There were no significant differences in the evaluation results of sEMG, FMA, and MBI of the lower limbs between the two groups of patients before the treatment (p > 0.05). After 4 weeks of treatment, compared with the control group, there were significant differences in the results of sEMG, FMA, and MBI of the lower limbs in the experimental group (p < 0.05). In the experimental group, the difference in sEMG was statistically significant (p < 0.05). After 8 weeks of treatment, compared with the control group, there were significant differences in the results of sEMG, FMA, and MBI of the lower limbs in the experimental group (p < 0.05). In the experimental group, the differences in the results of sEMG, FMA, and MBI of the lower limbs were statistically significant (p < 0.05). The inter-group comparison of the results of sEMG, FMA and MBI of the lower limbs was statistically significant (p < 0.05) in the control group.
FES-assisted rehabilitation cycling might promote the recovery of the motor function of the lower limbs in patients with stroke and improve the sEMG signal of the lower limbs.
探讨功能性电刺激（FES）辅助康复自行车运动对偏瘫中风患者下肢功能恢复的影响，并评估表面肌电图（sEMG）的评估价值。
本前瞻性研究共纳入 66 例伴有下肢偏瘫的中风患者，随机分为实验组和对照组，每组 33 例。实验组采用 FES 辅助康复自行车运动，对照组仅进行康复自行车运动，不设置刺激参数。在治疗前和治疗 4 周、8 周后，分别进行 sEMG 和 Fugl-Meyer 评估（FMA），并评估下肢改良巴氏指数（MBI）。
两组患者治疗前 sEMG、FMA 和下肢 MBI 的评估结果无统计学差异（p＞0.05）。治疗 4 周后，与对照组相比，实验组下肢 sEMG、FMA 和 MBI 的评估结果有显著差异（p＜0.05）。实验组 sEMG 的差异具有统计学意义（p＜0.05）。治疗 8 周后，与对照组相比，实验组下肢 sEMG、FMA 和 MBI 的评估结果有显著差异（p＜0.05）。实验组下肢 sEMG、FMA 和 MBI 的差异具有统计学意义（p＜0.05）。对照组 sEMG、FMA 和 MBI 的下肢评估结果的组间比较具有统计学意义（p＜0.05）。
FES 辅助康复自行车运动可能促进中风患者下肢运动功能的恢复，并改善下肢的 sEMG 信号。
