Abstract

PURPOSE: This study was conducted to analyze the effects of virtual reality inspiratory muscle training and conventional inspiratory muscle training on diaphragm movement and pulmonary function in patients with thoracic restriction.
METHODS: This study measured diaphragm movement, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), and thoracic mobility (upper, middle, and lower trunk) under two different conditions. Forty young women between 19 and 24 years of age who had no history of orthopedic symptoms for the last 6 months were divided into experimental and control groups. The experimental group performed virtual reality inspiratory muscle training and diaphragm breathing, and the control group performed conventional inspiratory muscle training and diaphragm breathing.
RESULTS: The control group showed a significant increase in all dependent variables except for lower trunk mobility and PEF. The experimental group showed a significant increase in all dependent variables except for lower trunk mobility. Particularly, the experimental group showed significant increases in diaphragm movement (p<.05), FVC (p<.05), FEV1 (p<.05), and PEF (p<.05) relative to the control group.
CONCLUSION: We recommend inspiratory muscle training with a virtual reality program over conventional training to improve diaphragm movement and pulmonary function in patients with thoracic restriction.
