To explore effect of repetitive transcranial magnetic stimulation (rTMS) combined with task-oriented training of lower limb motor function on the community walking ability and balance function in post-stroke patients. Methods: Eighty post-stroke patients were randomly divided into the experimental group and the control group, with 40 cases in each group. One case was lost in the experimental group and two cases were lost in the control group. Both groups of patients received routine rehabilitation training. The control group received rTMS treatment, while the experimental group received rTMS combined with task-oriented training of lower limb motor function. Interventions were implemented once daily, 5 days per week for 4 weeks. Functional assessments, including the Fugl-Meyer Assessment of Lower Extremity (FMA-LE), 10-meter walking test (10MWT), 6-minute walk distance (6MWD), timed up and go test (TUG), and instrumented balance function testing were conducted before and after interventions to assess the patients' postural stability limits. Results: After treatment, both groups presented improvements in FMA-LE, 10MWT, 6MWD, TUG, movement speed at limit displacement, maximum displacement, and endpoint displacement (P<0.05). However, the differences in reaction time and directional control at limit displacement were not statistically significant in the control group before and after intervention (P>0.05). Moreover, after treatment, the experimental group exhibited superior improvements in the observational indexes compared to the control group (P<0.05). Conclusion: The combination of rTMS and task-oriented training of lower limb motor function significantly improves community walking ability and balance function in post-stroke patients, with its efficacy superior to that of single rTMS treatment.
