Predicting physical functioning status in older adults: insights from wrist accelerometer sensors and derived digital biomarkers of physical activity.
Abstract
Conventional physical activity (PA) metrics derived from wearable sensors may not capture the cumulative, transitions from sedentary to active, and multidimensional patterns of PA, limiting the ability to predict physical function impairment (PFI) in older adults. This study aims to identify unique temporal patterns and develop novel digital biomarkers from wrist accelerometer data for predicting PFI and its subtypes using explainable artificial intelligence techniques.

Research summary
The paper addresses the prediction of physical function impairment in older adults using novel digital biomarkers derived from wearable sensors, which is relevant to understanding and potentially mitigating age-related decline in physical functioning. However, the focus on predicting impairment rather than addressing the root causes of aging or promoting lifespan extension limits its impact. The findings may contribute to the field of gerontology but do not represent a significant advancement in longevity research.
