Background: The development of mobile technologies has created an array of portable software and enabled development of new health applications in small devices that record, analyze, and process signals. We set out to determine the effectiveness of a new mobile system for interactive breathing exercises in thoracoabdominal mobility.
Material and Methods: Twelve healthy subjects (mean age 21.45±2.20 yrs) and five patients with restrictive lung dysfunction (mean age 41.4±17 yrs) participated. Protocol training consisted of five sets of 10 repetitions of deep inspiration in a new mobile health application (designed by our team), during a total of 12 sessions 3 times/week. The mobile application consisted of three main subcomponents: mobile real-time acquisition of physiological data, signal processing of data, and visual feedback as incentive to subjects during interactive breathing exercises. Participants were evaluated prior to and immediately following the respiratory incentive training protocol by thoracoabdominal mobility through the thoracoabdominal spirometry measurements.
Results: The respiratory incentive training protocol using the mobile application significantly increased thoracoabdominal mobility evaluated at three levels in Group 1 (healthy subjects) and at thoracic levels (axilar and xyphoidean) in Group 2 (subjects with restrictive dysfunction).
Conclusions: Results suggest our new respiratory incentive application is an effective method for training subjects, improving thoracoabdominal mobility.
