| Objective: To discuss the effect of comprehensive respiratory training on motor dysarthria in stroke patients. Methods: All 58 stroke patients with motor dysarthria were randomly divided into test group (30 cases) and control group (28 cases). The control group received basic articulation training, and the test group received comprehensive respiratory training on this basis, including respiratory control training, lip contraction-abdominal breathing training and threshold training of inspiratory muscle. Both groups were trained for 6 weeks. Before and after training, the curative effects of the two groups were evaluated by Frenchay dysarthria assessment (FDA), Maximum Phonation Time (MPT), Maximum counting ability (MCA) and pulmonary function test. Results: After 6 weeks of training, the FDA scores (8 items) in the test group were significantly reduced (P<0.01) and the FDA scores (except for respiratory items) in the control group were also significantly declined (P<0.01) as compared with those before training; the FDA scores of breath, lip movement, soft palate movement, throat movement, tongue movement and speech in test group were significantly lower than those in the control group (P<0.01 or 0.05). After 6 weeks of training, the values of MPT and MCA in the two groups were significantly higher than those before training (P<0.01), and the values of MPT and MCA in the test group were significantly different from those in the control group (P<0.01). As compared with those before training and after traning in the control group, the values of FVC, PEF and MIP in the test group were significantly increased (P<0.01), and only the FVC value in the control group was significantly increased (P<0.05). Conclusion: Comprehensive respiratory training can improve motor dysarthria and the coordination of speech and respiration in stroke patients. |
