Purpose This study investigated the effect of respiratory exercise on pulmonary function, balance, and gait in chronic stroke patients. Participants and Methods Twenty patients with chronic stroke were randomly assigned to experimental and control groups (n=10 each). The patients in both groups underwent neurodevelopmental treatment. Moreover, the experimental group performed respiratory exercise. Pulmonary function was measured using a pneumatometer. Balance was measured using a Berg Balance Scale and Functional Reach Test. Gait was measured with a 10-m walk test and Timed Up-and-Go Test. Results Intragroup comparison showed significant differences in forced vital capacity, forced expiratory volume in one second, Berg Balance Scale, Functional Reach Test, 10-meter walk test, and Timed Up-and-Go Test. Intergroup comparison showed that the differences in forced vital capacity, forced expiratory volume in one second, Berg Balance Scale, Functional Reach Test, 10-meter walk test, and Timed Up-and-Go Test for the experimental group were significantly related to those for the control group. Conclusion Based on these results it was concluded that respiratory exercise effectively improves the pulmonary function, balance, and gait in patients with chronic stroke.
