PURPOSE: This study was to find out an inspiratory muscle training (IMT) program therapeutic effects on stroke patients' functional ability. SUBJECTS AND METHODS: Twenty stroke patients were assigned to one of two groups: inspiratory muscle training (n = 10), and control (n = 10), randomization. The inspiratory muscle training participants undertook an exercise program for 30 minute per times, 5 times a week for 6 weeks. The investigator measured the patients' trunk impairment scale (TIS) and 6 minute walking test (6MWT) for functional ability before and after IMT. RESULTS: The TIS appeared some significant differences in both groups before and after the training. The 6MWT showed some significant differences in the inspiratory muscle training group, but didn't show any significant difference in the control group. And the differences in both groups after depending the inspiratory muscle training were significantly found in the tests of TIS and 6MWT. CONCLUSION: The results showed that the inspiratory muscle training in stroke patients are correlated with the trunk stability and locomotion ability, suggesting that physical therapist must take into consideration the inspiratory muscle training, as well as functional training to improve physical function in stroke patients.
