Continuous Measurement of the Activity for Clinical Evaluation at Home, for Non-ambulant Neuromuscular Patients

The main objective is the continuous measurement of muscle activity in a standardized setting and in the non ambulatory patient's natural environment. This measure uses an innovative technology based on accelerometer and magneto-inertial sensors. The system is intended to measure the physical activity of patients from the extraction of data recorded by the sensors in the three space axes.

The non ambulatory patients will be included and evaluated at baseline and 14 days later. The patients wear the accelerometer device during some standard evaluations and also at home continuously for 14 days.

With this protocol the investigators want to try to find the best variable that characterizes the movement of the upper limbs of non-ambulant neuromuscular patients.

The aim of Pre-Acti is to propose a primary outcome measure that may be used in clinical monitoring of patients.
