| Objective: To investigate the effects of walking pattern-based single-joint stimulation versus double-joint stimulation on lower limb function and changes in brain diffusion tension imaging (DTI) in convalescent patients with cerebral apoplexy. Methods: A total of 84 patients with stroke diagnosed in our hospital from March 2021 to March 2022 were randomly divided into multi-channel group (n=42) and double-channel group (n=42). The patients in the multi-channel group received the four-channel treatment mode of the FES therapeutic instrument, and those in the dual-channel group received the dual-channel treatment mode of the same FES therapeutic instrument. The lower limb motor function (FMA score), balance function (PASS score, BBS score, BBA score), walking function (Holden walking function grade) and activities of daily living (MBI score) were compared between the two groups after treatment for 1 week, 2 weeks and 3 weeks. The changes in related indexes (FA, rFA, RAasy) of magnetic resonance DTI were compared between the two groups at 3rd week after treatment. Results: After treatment for 1 week, 2 weeks and 3 weeks, the FMA score, PASS score, BBS score, BBA score and MBI score in the two groups were significantly higher than those before treatment, and there were significant differences between the two groups at each time point after treatment, especially in the multi-channel group (P<0.05). At 2nd and 3rd week after treatment, the improvement of Holden’s walking function in the multi-channel group was better than that in the dual-channel group (P<0.05). At 3rd week of treatment, the rFA in the two groups was signifi-cantly higher than that before treatment, and the FAasy was significantly lower than that before treatment, and there were significant differences in all indexes between the two groups. The changes of rFA and FAasy were more significant in the multi-channel group than in the dual-channel group (P<0.05). Conclusion: Multi-channel FES based on normal walking mode is more effective than dual-channel FES for stroke patients, and can significantly improve motor function, balance, walking function and activities of daily living. In addition, DTI suggested that multi-channel FES is more beneficial to the recovery of brain tissue lesions, which is significant to improve the rehabilitation treatment and prognosis of stroke patients. |
