Abstract
Objective: The purpose of this study was to confirm the validity of a respiratory retraining exercise using pressure biofeedback units among individuals with stroke as an effective intervention for improving quality of life.
Design: Randomized controlled trial.
Methods: Thirty patients with stroke were recruited as subjects. Among them, 15 patients were randomly assigned to an experimental group performing lumbar stabilization exercise and respiratory retraining exercise, and the other 15 patients were randomly assigned to a control group conducting only lumbar stabilization exercises. Exercises were conducted 3 times a week for 6 weeks, and quality of life was evaluated in the pre-test, 3 weeks and 6 weeks periods. The respiratory retraining exercises were performed using a pressure biofeedback unit and the degree of the quality of life was measured using the Stroke- Specific Quality of Life. For data analysis on the study results, a two-way repeated ANOVA was used in order to observe for changes in the measured variables according to time for both groups. If there was a reciprocal action between the groups and the time in the effect test within the entities, a one-way repeated ANOVA was implemented and was statistically processed.
Results: There was a significant difference in the main effect test between the 2 populations depending on the duration of the experiment (6 weeks) (p<0.05).
Conclusions: The above results showed that respiratory retraining exercises may provide positive effects in the treatment of stroke as the quality of life showed significant differences according to the duration of treatment.
