Abstract

[Purpose] In this study, we aimed to identify the effects of expiratory muscle training (EMT) on the respiratory muscle strength and cough intensity of stroke patients. [Subjects] The subjects were 22 stroke patients who had experienced a stroke within the previous 6 months and had been hospitalized for rehabilitation. They were divided into 2 groups: an EMT group, 10 patients (mean age: 69.3 years) assigned to undergo standard rehabilitation plus 4-week EMT; and a control group, 12 patients (mean age: 70.8 years) assigned to undergo standard rehabilitation alone. [Methods] The EMT group performed EMT (3 sets of 15 repetitions) twice a day, 5 times a week, for 4 weeks using a positive expiratory pressure device (ThresholdTM PEP). MEP, MIP, FVC, FEV1.0, PEF, and PCF were measured and compared between the 2 groups. [Results] At 4 weeks after the training, MEP and FEVl.0 had significantly increased in the EMT group compared with the control group, but no significant differences were observed in PEF or PCF. [Conclusion] EMT increased the respiratory muscle strength of stroke patients. However, further studies are required for assessment of the effect of EMT on the cough intensity.<br>
