Title : Potential Application of a Simple Prototype Inspiratory Muscle Device and Modified Fast- Deep Breathing Techniques via Voldyne Incentive Spirometry Enhances the Respiratory Function, Walking Capacity, and Quality of Life Among People with Chronic Obstructive Pulmonary Disease (COPD)
Chronic Obstructive Pulmonary Disease (COPD) is still the main problem of people around the world as in Thailand. Low quality of life with less exercise intolerance is a critical issue for rehabilitation. Therefore, the development of a simple device from folk materials for respiratory muscle training or modified training protocol are very challenged for the health team as medicine nurse, physical therapist, or rehabilitation physicians. Therefore, the objectives in the two published studies were (1) to develop a simple device from polyvinyl chloride (PVC)-plastic water pipe and plastic caps in which a center resister at 2, 4, and 6 mm and (2) to evaluate a fast-deep breathing technique via regular Voldyne® incentive spirometer on respiratory muscle function, walking capacity and quality of life among COPD people. The results of a simple inspiratory muscle training in 10 COPD people for 4 weeks showed that the forced vital capacity (FVC), respiratory muscle strength (PImax), walking capacity (6-MWD), and quality of life (QoL) were significant improvement as same as training with a standard respiratory muscle trainer (Portex® device). In addition, a result of the fast-deep breathing technique via voldyne® IS among 15 COPD people for 4 weeks showed improvement of the FVC, FEV1, PImax, 6-MWD, and QoL when compared to slow-deep breathing via Voldyne® IS. Therefore, both results indicate that the simple procedures for improving the health of COPD patients can be performed by developing a simple device and modifying a breathing technique and these can be learned for developed and low-economic countries around the world.
