Abstract

|
Purpose: The purpose of this study was to identify the effects of the application of inspiratory muscle training and complex breathing training on diaphragm thickness and respiratory function in individuals with chronic stroke.
Methods: A total of 30 patients were randomly divided into experimental and control group. The experimental group performed 30 minutes of inspiratory muscle training and complex breathing training and 30 minutes lower limb ergometer training for a total of 60 minutes, 3 times a week for 6 weeks. The control group performed 30 minutes of conventional physical therapy and 30 minutes lower limb ergometer training for a total of 60 minutes, 3 times a week for 6 weeks. The diaphragm thickness of the participants was measured by using rehabilitative ultrasound image, and a respiratory function test was conducted using a Pony FX spirometer. These parameters were evaluated prior to the intervention and 6 weeks after the intervention.
Results: In both groups, there was a significant difference (p<.05) between the results obtained before and after training. There was significant improvement in the affected and unaffected diaphragm thickness during contraction, as well as the respiratory function, in the experimental group compared to the control group (p<.05).
Conclusion: In this study, we confirmed that there are significant effects of inspiratory muscle training and complex breathing training on diaphragm thickness and respiratory function in patients with chronic stroke.
