Validity and Comparability of a Wrist-Worn Accelerometer in Children.
BACKGROUND: Wrist-worn accelerometers may provide an alternative to hip-worn monitors for assessing physical activity as they are easier to wear and may thus facilitate long-term recordings. The present study aimed at a) assessing the validity of the Actiwatch (wrist-worn) for estimating energy expenditure b) determine cut-off values for light, moderate and vigorous activities, c) studying the ...
متن کاملCalibration and Validation of a Wrist- and Hip-Worn Actigraph Accelerometer in 4-Year-Old Children
INTRODUCTION To determine time spent at different physical activity intensities, accelerometers need calibration. The aim of this study was to develop and cross-validate intensity thresholds for the Actigraph GT3X+ accelerometer for wrist and hip placement in four-year-old children. METHODS In total 30 children (49 months, SD 3.7) were recruited from five preschools in Stockholm. Equipped wit...
متن کاملStride 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 کاملActivities of Daily Life (ADL) Recognition using Wrist-worn Accelerometer
Activity recognition has become the necessity of smart homes, future factories, and surveillance. Activities independent of body posture predominantly exhibiting gestures involving both arm and the wrist motion supports the use of the wearable sensors for data acquisition. This paper uses an algorithm based prediction method to recognize the Activities of Daily Life (ADL) involving activities l...
متن کاملTechnical variability of the Vivago® wrist-worn accelerometer.
The aim was to assess the technical variability of a new wrist-worn accelerometer under controlled conditions with a shaker device and during normal daily physical activities (PAs). In the first experiment, 10 wrist-worn accelerometers (Vivago(®) Wellness, Paris, France) were attached to the shaker device. Variability was tested at five shaking frequencies (1.1, 2.1, 3.1, 4.1, and 10 Hz) for 10...
