The general aim is to devise effective means of addressing the demands of assisted living, rehabilitation, and clinical observation and assessment through sensor-based monitoring. The research studies have resulted in a large amount of literature. This paper presents a holistic articulation of the research studies and offers comprehensive insights along four main axes: distribution of existing studies; monitoring device framework and sensor types; data collection, processing and analysis; and applications, limitations and challenges. The aim is to present a systematic and most complete study of literature in the area in order to identify research gaps and prioritize future research directions.<\/jats:p>","DOI":"10.3390\/s131012852","type":"journal-article","created":{"date-parts":[[2013,9,25]],"date-time":"2013-09-25T12:47:40Z","timestamp":1380113260000},"page":"12852-12902","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":171,"title":["Real-Time Human Ambulation, Activity, and Physiological Monitoring: Taxonomy of Issues, Techniques, Applications, Challenges and Limitations"],"prefix":"10.3390","volume":"13","author":[{"given":"Rinat","family":"Khusainov","sequence":"first","affiliation":[{"name":"School of Engineering, Faculty of Technology, University of Portsmouth, Anglesea Building, Anglesea Road, Portsmouth PO1 3DJ, UK"}]},{"given":"Djamel","family":"Azzi","sequence":"additional","affiliation":[{"name":"School of Engineering, Faculty of Technology, University of Portsmouth, Anglesea Building, Anglesea Road, Portsmouth PO1 3DJ, UK"}]},{"given":"Ifeyinwa","family":"Achumba","sequence":"additional","affiliation":[{"name":"School of Engineering, Faculty of Technology, University of Portsmouth, Anglesea Building, Anglesea Road, Portsmouth PO1 3DJ, UK"}]},{"given":"Sebastian","family":"Bersch","sequence":"additional","affiliation":[{"name":"School of Engineering, Faculty of Technology, University of Portsmouth, Anglesea Building, Anglesea Road, Portsmouth PO1 3DJ, UK"}]}],"member":"1968","published-online":{"date-parts":[[2013,9,25]]},"reference":[{"key":"ref_1","unstructured":"UN (United Nations) Available online http:\/\/esa.un.org\/wpp\/Other-Information\/Press_Release_WPP2010.pdf."},{"key":"ref_2","unstructured":"Willis, D.J.
