BackgroundRespiratory rehabilitation reduces breathlessness from patient with respiratory dysfunction. Chest expansion score, which represents the circumference magnitude of the thoracic cage, is used for a target when treating patients with respiratory disease. However, it is often difficult for patients to understand the changes in the respiratory status and be motivated for therapy continuously. We developed a new measurement system with biofeedback named BREATH which shows chest expansion scores in real time. The purpose of this study was to determine the reliability and validity of the novel system in advance of clinical application.MethodsThree evaluators measured chest expansion in 33 healthy individuals using tape measure, which is used for the measurement traditionally, and BREATH. The wire for BREATH system was threaded over the thoracic continuously and the data was recorded automatically; whereas the tape was winded and measured each maximal expiration and inspiration timing by evaluator. All participants were performed both measurement simultaneously for three times during deep breath. In this study, we studied chest expansion score without using biofeedback data of BREATH to check the validity of the result. To confirm intra- and inter-evaluator reliability, we computed intra-class correlations (ICCs). We used Pearson’s correlation coefficient to evaluate the validity of measurement result by BREATH with reference to the tape measure results.ResultsThe average (standard deviation) chest expansion scores for all, men and women by the tape measure were 5.53 (1.88), 6.40 (1.69) and 5.22 (1.39) cm, respectively, and those by BREATH were 3.89 (2.04), 4.36 (1.83) and 2.89 (1.66) cm, respectively. ICC within and among the three evaluators for BREATH and the tape measure were 0.90-0.94 and 0.85-0.94 and 0.85 and 0.82, respectively. The correlation coefficient between the two methods was 0.76-0.87.ConclusionThe novel measurement system, BREATH, has high intra- and inter-evaluator reliabilities and validity; therefore it can lead us more effective respiratory exercise. Using its biofeedback data, this system may help patients with respiratory disease to do exercises more efficiently and clinicians to assess the respiratory exercise more accurately.

“…A wireless breathing support system was assembled by an optical sensor, an accelerometer, a microcontroller, a Bluetooth module and a laptop computer for remote staying physicians. The optical sensor, which is attached to the patient's chest, measures chest circumference and outputs the variations of circumference (referencing the breathing pattern) as serial digital data [10].…”

“…An instrument to evaluate and calculate the volume of air inspired and expired by the lungs was devised by Tawa, H. et al in 2009. The system was composed of an optical sensor (which was attached to the patient's chest and measures chest circumference), an accelerometer, a microcontroller, a Bluetooth module and a laptop computer [13]. In year 2010, Lipi Mohanty and Kevin S. C. Kuang invented a breathing rate sensor with plastic optical fiber, demonstrating the ability to quantify the breathing rate and monitor different breathing patterns up to a resolution of 1 breath/second (1 Hz).…”

This paper presents a cost effective on-line ventilation monitoring system for impaired elderly persons using optical wireless sensory system. In this work, we have tried to develop this system especially for aged physically disabled people by introducing a cordless optics based sensing system as a secondary transducer which carries many distinctive features like i) no electrical signal is directly connected with the subject's body, thus providing a shock hazard free module, ii) any hardware interfacing circuit (for computer compatible signal) not required which again minimizes complex circuitry and finally generates iii) a noise free computer friendly output. The processor analyses the signal and communicates information to the distantly located physicians through blue tooth technology. Here, we have developed an algorithm which monitors important spirometric values such as Forced Expiratory Volume of air in first one second (FEV1), Forced Vital Capacity (FVC) and PeakExpiratory Flow (PEF) continuously, so that any deviation from the safe limits will allow the system to send a warning sign to the physician's mobile and at the same time it will send numerical and graphical respiratory information of the subject to the webserver. Our study is limited to two common respiratory diseases like chronic obstructive pulmonary disease (COPD) and chronic restrictive pulmonary disease (CRPD). We have studied the respiratory activities of 50 male impaired elderly persons. The sent information through the wireless technology using telemetering platform was in very close agreement with the actual clinical conditions.

Improvement of thoracic mobility is important for patients with diseases such as chronic obstructive pulmonary disease (COPD). Chest expansion training is often conducted to increase the thoracic excursion. However, it is difficult for the patients to keep the motivation for rehabilitation, because the chest excursion is only measured. In this paper, we analyze the effect of real-time biofeedback on thoracic excursion. In 30 healthy subjects, thoracic excursion was increased by 6 mm (17%) when using the biofeedback system. Our results confirmed that we have developed an effective system for rehabilitation of respiratory function.
