A new general medical journal for the 21st centrury, focusing on innovation in health and medical research
i-JMR is a general medical journal with a focus on innovation in health, health care, and medicine - through new medical techniques and innovative ideas and/or research, including - but not limited to - technology, clinical informatics, sociotechnical and organizational health care innovations, or groundbreaking research.
Published by JMIR Publications, publisher of JMIR, the leading eHealth/mHealth journal (Impact Factor 2016: 5.175), i-JMR is a JMIR "sister journal" with a projected impact factor of about 2.03 (2016). which features a rapid and thorough peer-review process, professional copyediting, professional production of PDF, XHTML, and XML proofs.
i-JMR is indexed in PubMed and archived in PubMed Central.

Background: Utilization of several research and consumer grade activity monitors for quantification of Physical Activity has created an uncertainty due to imprecise measurement. Objective: The aim of this analysis was to determine the impact of different activity monitors for quantifying PA among the sedentary population for accurate measurement of EE, MET and Temporospatial parameters of Gait Methods: 8 databases were searched from 2010 till present out of which only 16 articles were selected for qualitative (n=9) and quantitative (n=7) analysis. Accelerometers with sedentary lifestyle population was selected with TSPs, EE, MET, 6MWT as outcome measures. Quality assessment was conducted using Tool for assessing risk of bias considering Cochrane Collaboration. Accelerometers were categorized into a) actigraphy, b) activPAL c) mixed accelerometers, d) New generation accelerometers Results: Out of 105 studies only 16 studies (2542 participants) met the inclusion criteria. The result obtained from the quantitative analysis of study shows that activPAL had more validity than any of the other accelerometers for the quantification of the Physical Activity in free living environment for sedentary behavior with the pooled effect of 0.966 under fixed effect model followed by new generation accelerometers 0.771, mixed accelerometers 0.71 and actiGraph older generation 0.682. Conclusions: Evidences presented in the paper reveals that a paradigm shift has been seen from subjective measurement approach to objective measurement due to availability of several types of accelerometers. activPAL has found to effective in quantification of PA during life style behaviors
