Purpose To assess the influence of anatomical placement of an accelerometer on physical activity energy expenditure (PAEE) prediction in manual wheelchair users. Methods Ten accelerometer units (Actigraph GT3X+) were attached to a multi-axis shaker table and subjected to a sinusoidal oscillation procedure to assess mechanical validity and reliability. Fifteen ...
Objectives: The goals of this study were to validate the use of accelerometers by means of multiple linear models (MLMs) to estimate the O2 consumption (VO2) in paraplegic persons and to determine the best placement for accelerometers on the human body. Methods: Twenty participants (age=40.03 years, weight=75.8 kg and height=1.76 ...
Physical activity monitors can quantify various types of Physical Activities (PAs) in Manual Wheelchair Users (MWUs) with Spinal Cord Injury (SCI). The objective of this study was to develop new energy expenditure (EE) prediction models for MWUs with SCI based on an ActiGraph activity monitor. A total of 45 MWUs with ...
Background: Research has indicated that actigraphy is valid and reliable for measuring low levels of physical activity among ambulatory individuals, and that it may be a valid indicator of energy expenditure for wheelchair users in laboratory conditions, but there are no reports of its evaluation in free-living conditions. Objective: To ...
Study design: Cross-sectional validation study. Objectives: The goals of this study were to validate the use of accelerometers by means of multiple linear models (MLMs) to estimate the O2 consumption (VO2) in paraplegic persons and to determine the best placement for accelerometers on the human body. Setting: Non-hospitalized paraplegics’ community. ...
Background Observational studies have shown a positive association between time outdoors and physical activity in children. Time outdoors may be a feasible intervention target to increase the physical activity of youth, but methods are required to accurately measure time spent outdoors in a range of locations and over a sustained ...
