Objective: To investigate the impact of modified Baduanjin on lower limb motor control abilities in stroke patients. Methods: A total of 58 stroke patients were randomly divided into an experimental group and a control group (29 cases in each group). The control group received conventional rehabilitation therapy, and the experimental group received modified Baduanjin combined with conventional rehabilitation therapy once a day, 5 days a week for 6 weeks. Both two patients in the experimental group and the control group withdrew from the study, resulting in a final sample size of 27 patients in the two groups.Assessments were conducted before and after the intervention using the lower limb portion of the Fugl-Meyer Assessment (FMA-LE), the Berg Balance Scale (BBS), and the three-dimensional motion analysis system with the sacral landmark method to measure the mean sway amplitude (MSA) during standing with eyes open and closed. Surface electromyography was utilized to evaluate the integrated electromyography (iEMG) value of the affected limb’s muscle groups and to calculate the co-contraction rate (CCR) of knee flexion and extension. Results: After 6 weeks of intervention, within-group comparisons showed that the FMA-LE, BBS, iEMG values of the lower limb muscle groups significantly increased in both groups (P<0.01). Additionally, the MSA values in the X and Y axis during standing with eyes open and closed and knee flexion-extension CCR values significantly decreased (P<0.01). Inter-group comparisons revealed that the FMA-LE, BBS, iEMG values of the rectus femoris and biceps femorisgroup, were significantly higher than those in the control group (P<0.01,0.05). Furthermore, the Y-axis MSA value during standing with eyes open in the experimental group , as well as the knee extension CCR value in the experimental was significantly lower than that in the control group (P<0.05). Conclusion: A 6-week modified Baduanjin training can significantly improve the lower limb motor control abilities of stroke patients, specifically reflected in the enhancement of overall lower limb functional movement, muscle coordination, and balance abilities. |
