Background This study aimed to explore the acceptability of a wearable device for remotely
measuring mobility in the Mobilise-D technical validation study (TVS), and to explore the …

Purpose Whether the association between objectively assessed physical activity and
mortality differs between adults with versus those without frailty is unclear. We investigated …

Objectives Daily step counts are an easy-to-understand indicator of physical activity;
however, there is limited evidence regarding the optimal daily step count to prevent …

This review examined literature that has examined mobility in pulmonary arterial
hypertension (PAH) using digital technology. Specifically, the review focussed on:(a) digital …

Background There are now many different types of activity trackers, including pedometers
and accelerometers, to estimate step counts per day. Previous research has extensively …

Background: For older adults with severe aortic stenosis (AS) undergoing aortic valve
replacement (AVR), recovery of physical function is important, yet few studies objectively …

Background Wrist-worn data from commercially available devices has potential to
characterize sedentary time for research and for clinical and public health applications. We …

Step cadence‐based and machine‐learning (ML) methods have been used to classify
physical activity (PA) intensity in health‐related research. This study examined the …

Objective Assessment of Physical Activity at Home Using a Novel Floor-Vibration Monitoring
System: Validation and Comparison With Wearable Activity Trackers and Indirect …

Objectives: Currently available questionnaires have limited ability to measure physical
activity (PA) using accelerometers as a gold standard. This study aimed to develop a PA …
