Stride variability measures derived from wrist- and hip-worn accelerometers.
Many epidemiological and clinical studies use accelerometry to objectively measure physical activity using the activity counts, vector magnitude, or number of steps. These measures use just a fraction of the information in the raw accelerometry data as they are typically summarized at the minute level. To address this problem, we define and estimate two measures of temporal stride-to-stride gai...
متن کاملValidation and Comparison of Accelerometers Worn on the Hip, Thigh, and Wrists for Measuring Physical Activity and Sedentary Behavior
Background Recent evidence suggests that physical activity (PA) and sedentary behavior (SB) exert independent effects on health. Therefore, measurement methods that can accurately assess both constructs are needed. Objective To compare the accuracy of accelerometers placed on the hip, thigh, and wrists, coupled with machine learning models, for measurement of PA intensity category (SB, light-...
متن کاملLab-based validation of different data processing methods for wrist-worn ActiGraph accelerometers in young adults.
The wrist is increasingly being used as the preferred site for objectively assessing physical activity but the relative accuracy of processing methods for wrist data has not been determined. OBJECTIVE This study evaluates the validity of four processing methods for wrist-worn ActiGraph (AG) data against energy expenditure (EE) measured using a portable metabolic analyzer (OM; Oxycon mobile) a...
متن کاملLarge Scale Population Assessment of Physical Activity Using Wrist Worn Accelerometers: The UK Biobank Study
BACKGROUND Physical activity has not been objectively measured in prospective cohorts with sufficiently large numbers to reliably detect associations with multiple health outcomes. Technological advances now make this possible. We describe the methods used to collect and analyse accelerometer measured physical activity in over 100,000 participants of the UK Biobank study, and report variation b...
متن کاملWrist-Worn Light-Based Smart Digital Jewellery
Dr.-Ing. Jutta Fortmann Wrist-Worn Light-Based Smart Digital Jewellery In recent years wearable devices have become an emerging trend in the consumer market. However, recent studies in the U.S. show that a third of owners of a wearable device abandon its use within six months. Supposed reasons are, among others, a lack in useful functions, aesthetics, and comfort. Smart Digital Jewellery has be...
