Non-communicable chronic diseases (NCDs), such as diabetes, have been a leading cause of morbidity, mortality and health care expenditures in most developed countries including Canada, and appear to be on the rise. The pivotal role of physical activity in improving NCD patients' rehabilitation has been widely recognized, which requests thorough understanding of muscle oxygenation. Recently, technology based on near-infrared spectroscopy (NIRS) has been proposed as a promising way to investigate muscle metabolism because of its noninvasive and portable nature. Although it is promising, applying NIRS technology for muscle metabolism measurement is challenging due to the complex profiles of noise, interference, and distortion to the received signal, and the high computational complexity resulting from the application of advanced signal processing techniques. All these challenges have prevented industrial companies from developing commercial muscle metabolism monitors based on the NIRS technology.To well address all aforementioned challenges, this project will focus on developing a new implementation platform through integrating the state of art technologies in signal processing and mobile communications. Specifically, with meaningful industrial and academic collaborations, this work will develop 1) a new specified software platform for quantitative muscle oxygenation saturation (SmO2) measurement over a newly fabricated near-infrared sensor; and 2) novel protocols and algorithms addressing the adoption of mobile edge computing for real-time monitoring. This cutting-edge research will generate new ideas and knowledge in NIRS analysis and mobile edge computing, and, through collaborations, enable the development of new commercial products that will foster a vital competitive edge for Canadian healthcare industry in the international market place.
