Freezing of gait (FOG) is a disabling symptom that common among patients with advanced Parkinson's disease (PD). External cues such as rhythmic auditory stimulation can help PD experiencing freezing to resume walking. Wearable systems for automatic detection have been recently developed. However, these detect FOG episode after it has happened. Instead, in the present study new approach prediction (before actually happens) presented. Prediction might enable preventive cueing, reducing...
Existing mobility endpoints based on functional performance, physical assessments and patient self-reporting are often affected by lack of sensitivity, limiting their utility in clinical practice. Wearable devices including inertial measurement units (IMUs) can overcome these limitations quantifying digital outcomes (DMOs) both during supervised structured real-world conditions. The validity IMU-based methods the real-world, however, is still limited populations. Rigorous validation...
Introduction: Accurately assessing people’s gait, especially in real-world conditions and case of impaired mobility, is still a challenge due to intrinsic extrinsic factors resulting gait complexity. To improve the estimation gait-related digital mobility outcomes (DMOs) scenarios, this study presents wearable multi-sensor system (INDIP), integrating complementary sensing approaches (two plantar pressure insoles, three inertial units two distance sensors). Methods: The INDIP technical...
