Abstract
Purpose: This study aimed to investigate the effects of tDCS combined with PNF on trunk muscle activity and pulmonary function in stroke patients.
Methods: Thity stroke patients were taken as the study subjects and randomly divided into experimental and control groups, each with 15 patients. tDCS combined with PNF stabilization exercise was applied to the experimental group, and sham tDCS combined with PNF stabilization exercise was applied to the control group. Both groups were treated for 6 weeks, 5 times a week for 30 minutes each time; the trunk muscle activity and pulmonary function of stroke patients were measured before and after treatment, and the changes in the two groups were compared and analyzed.
Results: The rectus abdominis (RA), external oblique (EO), internal oblique (IO), and erector spinae (ES) muscle activities of the experimental group were significantly higher after treatment than those of the control group when the differences in trunk muscle activity between groups were compared before and after treatment (p<.05). In a comparison of changes in pulmonary function between groups after treatment, the experimental group’s maximum inspiratory pressure (MIP) and peak inspiratory flow (PIF) were significantly better than the control group’s (p<.05).
Conclusion: The improvement of trunk muscle activity and pulmonary function in stroke patients can be attributed to using of tDCS in combination with PNF stabilization exercise. This clinically helpful treatment method for stroke patients merits further promotion and implementation in the clinic.
