| ABSTRACT |
PURPOSE:
Respiratory function can be adversely affected after a cerebrovascular accident. This study aimed to determine whether inspiratory muscle training (IMT) changes the respiration and balance abilities of patients with stroke.
METHODS:
Twelve patients with stroke were randomly assigned to the study (n=6) and control (n=6) groups. The study and control groups received IMT and general physical therapy, respectively for 6 weeks, five times a week for 30 min/day. Inspiratory and expiratory functions and balance were measured pre- and post-evaluation.
RESULTS:
After IMT intervention, the weight distribution ratio (WDR) for balance ability measurement was significantly decreased (p<.05), and the maximum inspiratory pressure (MIP), maximum inspiratory flow rate (MIFR), maximum inspiratory capacity (MIC), peak expiratory flow (PEF), forced expiratory volume in 1 second (FEV1), and limits of stability (LOS) were significantly increased in the study group (p<.05). A comparison of the study and control groups revealed statistically significant differences in MIP (p<0.01), MIFR (p<.01), MIC (p<.05), PEF (p<.05), FEV1 (p<.05), WDR (p<.01), and LOS (p<.05).
CONCLUSIONS:
This study suggests that IMT is a useful and effective exercise intervention for patients with stroke. |
