Physical mobility is essential to health, and patients often rate it as a high-priority clinical
outcome. Digital mobility outcomes (DMOs), such as real-world gait speed or step count …

Walking/gait quality is a useful clinical tool to assess general health and is now broadly
described as the sixth vital sign. This has been mediated by advances in sensing …

Digital health technologies enable remote and therefore frequent measurement of motor
signs, potentially providing reliable and valid estimates of motor sign severity and …

Parkinson's disease (PD) is the fastest-growing neurological disease in the world. A key
challenge in PD is tracking disease severity, progression, and medication response. Existing …

Background Although digital mobility outcomes (DMOs) can be readily calculated from real-
world data collected with wearable devices and ad-hoc algorithms, technical validation is …

Many algorithms use 3D accelerometer and/or gyroscope data from inertial measurement
unit (IMU) sensors to detect gait events (ie, initial and final foot contact). However, these …

This study aimed to validate a wearable device's walking speed estimation pipeline,
considering complexity, speed, and walking bout duration. The goal was to provide …

The evidence of the responsiveness of dopaminergic medication on gait in patients with
Parkinson's disease is contradicting. This could be due to differences in complexity of the …

Objective The aim of this study was to establish the test–retest reliability of metrics obtained
from wearable inertial sensors that reflect turning performance during tasks designed to …

Background: In recent years, researchers have been advocating for the integration of
ambulatory gait monitoring as a complementary approach to traditional fall risk …
