Introduction: Although numerous activity trackers have been validated in healthy populations, validation is lacking in chronic heart failure patients who normally walk at a slower pace, making it difficult for researchers and clinicians to implement activity monitors during physical activity interventions.
Methods: Six consumer-level activity monitors were validated in a 3...
Purpose
Study purposes were to develop energy expenditure (EE) prediction models from raw accelerometer data and to investigate the performance of three different accelerometers on five different wear positions in preschoolers.
Methods
Fourty-one children (54% boys; 3–6.3 years) wore two Actigraph GT3X (left and right hip), three GENEActiv (right hip, left ...
Objective
Validated the Apple Watch (AW), Fitbit Surge HR (FS), TomTom Multisport Cardio Watch (TT), and Microsoft Band (MB) in energy expenditure (EE), average heart rate (HR), and peak HR assessment during exergaming.
Materials and Methods
Twenty-one college students participated in this study in Spring 2016. A 20-minute boxing session was ...

Objective
To parameterize and validate two existing algorithms for identifying out-of-bed time using 24 h hip-worn accelerometer data from older women.
Approach
Overall, 628 women (80 ± 6 years old) wore ActiGraph GT3X+ accelerometers 24 h d−1 for up to 7 d and concurrently completed sleep-logs. Trained staff used a validated visual analysis protocol to measure ...
Background
Remote monitoring of physical activity in patients with chronic conditions could be useful to offer care professionals real-time assessment of their patient’s daily activity pattern to adjust appropriate treatment. However, the validity of commercially available activity trackers that can be used for telemonitoring purposes is limited.
Objective
The ...
Introduction
Sleep disturbances in TBI population can have negative consequences on physical, psychological and cognitive recovery. While polysomnography (PSG) is the gold standard for evaluating sleep disorders, actigraphy has been widely used to screen for sleep-wake disorders, especially ones that change longitudinally. In a small sample of TBI patients (n=50, ...
Background
This study aimed to investigate the validity of the Active Australia Survey across different subgroups and its responsiveness to change, as few previous studies have examined this.
Methods
The Active Australia Survey was validated against the ActiGraph as an objective measure of physical activity. Participants (n = 465) wore the ActiGraph ...
Objectives
(1) Assess the accuracy of the ActiGraph wGT3x-BT accelerometer to count steps taken by inpatients with incomplete spinal cord injury (iSCI) in physical therapy (PT) sessions and self-directed activities, and (2) compare the number of steps/min taken in PT sessions to that in self-directed activities during inpatient rehabilitation.
Setting
...
Objective
To determine the validity of the ActiGraph GT3X accelerometer in step count quantification when compared to observed step count in hospitalised adults recovering from critical illness.
Setting
Large National Health Service (NHS) Hospitals Trust.
Subjects
In total, 20 hospital ward-based adults (age: mean 62.3, SD 11.5) who had required greater than 48 ...
