Development and Validation of an Actimetric Protocol to Quantify Physical Activity and Sedentary Behaviour in Post-stroke Subjects

Development and Validation of an Actimetric Protocol to Quantify Physical Activity and Sedentary Behaviour in Post-stroke Subjects

The aim of this project is to develop an actimetry protocol based on a system of motion sensors, such as accelerometers and pressure insoles.

These sensors will be used to analyze arm and leg movements in individuals who have experienced a stroke. Throughout the study, the investigators will adjust certain parameters-such as sensor placement and measurement frequency-to optimize data quality.

They will also refine data analysis methods to better identify the types of movements performed (upper and lower limbs), estimate energy expenditure, and recognize different postures adopted by the participant (sitting, standing, etc.).

The goal of this protocol is to provide accurate measurements of physical activity and inactivity, both in controlled environments (such as a laboratory) and in real-life settings (outdoors or at home).

This study will allow us to validate the reliability of the actimetry protocol and assess how easy it is to use at home.
