Abstract

Purpose: The aim of the present study was to investigate the effect of a PNF orofacial exercise program on diadochokinesis in subacute stroke patients with dysarthria. Methods: Thirteen subacute stroke inpatients with dysarthria were recruited for the study. All participants were randomly assigned to two groups: an experimental group (n=7) and a control group (n=6). The experimental group performed a PNF orofacial exercise program, and the control group carried out an orofacial self-exercise. Both groups received the treatments 30 minutes per day, 5 days per week, for 4 weeks. The outcome measures were assessed before and after the intervention, including an alternating motion rate (AMR) and sequential motion rate for diadochokinesis. Results: After the intervention, both groups showed significant improvement in diadochokinesis (p<0.05). In the change values for both groups, the experimental group showed a more significant improvement than the control group did in /pə/ of AMR (p<0.05). Conclusion: These findings suggest that PNF orofacial exercise programs may have positive effects on the improvement of diadochokinesis in subacute stroke patients with dysarthria.
