“…However, the same was not true for persons with MS, as efforts for generating condition-specific accelerometer cut-points among this population had not begun until 2009. The generation of cut-points involves calibrating the relationship between accelerometer output (i.e., counts/minute) and energy expenditure (i.e., metabolic equivalents [METs]), thereby determining the number of activity counts per minute that correspond with different intensities of physical activity (i.e., moderate intensity = 3 METS; vigorous intensity = 6 METS) [29,30]. …”

“…The ActiGraph 7164 uses a piezoelectric sensing component, which is more sensitive to slow movement, compared with the microelectromechanical sensing component used by the ActiGraph GT3X accelerometer and the latest models [30,38]. This prompted the importance of comparability of outputs for slow movements among different generations of ActiGraph accelerometers now afforded by the low frequency extension (LFE) option in the ActiLife software.…”

“…Multisensor devices incorporate multiple sensors for measuring different motion, physiological, and environmental variables, including body acceleration, temperature, heart rate, respiratory ventilation, and luminosity, as examples [30,75,76]. The SenseWear Armband (SWA), which has been discontinued, is one of the most commonly used multisensor in physical activity research.…”

Introduction: The use of motion sensors for measuring physical activity in multiple sclerosis (MS) has evolved with increasing research particularly during the past decade. Areas covered: This manuscript reviews the literature regarding the application of motion sensors for measuring physical activity in MS. We first describe ‘what is known’ about their use in MS by examining the evidence generated between 1997 and 2012, including the psychometric properties of motion sensors in MS and the development of MS-specific accelerometer cut-points. We then evaluate ‘what is new’ based on research conducted between 2013 and 2017. This includes newer research on psychometric properties of motion sensors in MS, development of new MS-specific accelerometer and step-rate cut-points, sedentary behavior assessment, and research on fitness trackers and multisensors in MS. The final part presents a picture of “what is next” for the applications of motion sensors in MS, especially pertaining new opportunities for testing and using fitness trackers in MS, and tracking disease and disability progression based on motion sensor output. Expert commentary: The use of motion sensors in MS has grown substantially over the years; however, a lot more can be done to explore the full potential and utility of these devices in MS.

“…• Posicionamento do acelerômetro: para mensuração da AF, os acelerômetros devem ser bem fixados no corpo do participante por meio de uma cinta (geralmente elástica) ou pulseira no local escolhido (por exemplo, quadril, punho). A correta fixação minimiza as vibrações e deslocamentos que acarretam ruído/ artefato na medida do movimento 21 . Os principais locais para utilização do acelerômetro são: quadril, punhos, região anterior e posterior da caixa torácica, coxas e tornozelo 21,22 .…”

The aim of this study was to develop instructions for using accelerometers to measure physical activity in Brazil. This manuscript is a review and synthesis of scientific papers that have used accelerometers for objective physical activity assessment in different age groups as well as studies providing directions for using activity monitors in large-scale studies. In this study, we present instructions for the pre-data collection (selection of monitor; unit calibration, firmware update, pilot study, protocol definition), data collection (monitor distribution, contacting participants, monitor return) and post-data collection (data processing, transformation and interpretation) phases. We describe procedures for facilitating decision making related to using accelerometers, as well as for obtaining valid and reliable accelerometer physical activity data. This set of instructions is an initiative of a group of physical activity researchers with the purpose of contributing to methodologically advance the field of objective physical activity measurement in Brazil. The current set of instructions intend to facilitate the standardization of procedures for collecting physical activity data with accelerometers in Brazil and, thus, for ascertaining future comparability of data collected in different studies.

Interventions Using Wearable Physical Activity Trackers Among Adults With Cardiometabolic Conditions

et al. 2021

View full text Add to dashboard Cite

Key Points Question Are interventions using wearable physical activity (PA) trackers, including accelerometers, fitness trackers, and/or pedometers, associated with improved PA levels among people with cardiometabolic conditions? Findings In this systematic review and meta-analysis of 38 randomized clinical trials with 4203 participants, interventions with wearable PA trackers were associated with significantly increased PA levels during approximately 15-weeks follow-up; interventions (particularly pedometers) with additional components, such as consultations with health care professionals, were associated with increased PA levels. Meaning The findings suggest that use of wearable PA trackers (especially pedometers) is associated with increased PA levels among people with cardiometabolic conditions when combined with additional intervention components, such as face-to-face consultations, but these PA level improvements may remain below the targets set by clinical recommendations.
