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

Condition(s) studied

Investigational drug(s) / intervention(s)

Actimetry Protocol: Our goal is to develop an actimetry protocol using both accelerometers and pressure insoles to quantify physical activity, involving the upper and/or lower limbs, as well as sedentary behavior in post-stroke individuals. Recent studies have explored the use of validated accelerometer configurations designed for healthy individuals, applied to the post-stroke population to monitor their physical activity and sedentary behavior. However, although these protocols have been validated for healthy individuals, they need to be adapted for post-stroke patients, who exhibit slower, asymmetric, and lower-amplitude movements compared to healthy subjects. This protocol could be valuable in both clinical practice and research, helping to optimize stroke rehabilitation and promote a healthy, active lifestyle.

Study summary

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.
