Measuring the Concurrent Validity of the Upper Limb Use Ratio With Accelerometers in an Ecological Situation After Stroke.
- Conditions
- Cerebrovascular Accident
- Interventions
- Behavioral: Objective assessment of upper limb use during activities in ecological situation
- Registration Number
- NCT06509542
- Lead Sponsor
- University Hospital, Montpellier
- Brief Summary
The purpose of this stufy is to measure the concurrent validity of the upper limb use ratio with accelerometers in an ecological situation after stroke.
- Detailed Description
The first visit will be used to present the study and potential risks to patients, obtain their consent and collect clinical data. A second visit is planned for the patients who meet the eligibility requirements, to carry out activities in ecological situation.

Group Intervention Description Measure of FuncUseRatio using wrist-worn accelerometers and videos Objective assessment of upper limb use during activities in ecological situation The wristbands are made from hypoallergenic silicone and weigh 27 grams. They contain three accelerometers (AX3, Axivity, Newcastle Helix, United Kingdom), recording data in the three planes of space at a sampling frequency of 50 Hz and within an acceleration range of ±8 g. The wristbands will be worn on each wrist during the activities. Two high-definition video cameras, recording at least 50 images per second, will be positioned so that the movements of the patient's upper limbs are always visible. The location of the cameras will depend on the activity and the configuration of the room in which it takes place.
- Primary Outcome Measures
Name Time Method Concurrent validity (Intraclass Correlation Coefficient) of FuncUseRatio, using wrist-worn accelerometers, compared with the FuncUseRatio measured by video analysis. Baseline FuncUseRatio is the ratio of functional use of the paretic upper arm to the non-paretic upper arm measured by two methods (actimetry and video analysis),during the same occupational therapy sessions simulating activities of daily living with hemiparetic patients.
- Secondary Outcome Measures
Name Time Method Ratio of the acceleration vector magnitude Baseline The magnitude of the acceleration vector is the norm of the acceleration vector (SVM: Scalar Vector Magnitude) minus 1 for the gravitational force. The ratio between the paretic and non paretic arm is then calculated
Activity count ratio Baseline The activity count is the magnitude of the acceleration vector summed per second for each arm, and converted into an activity count (0.01664g/count). The ratio between the paretic and the non-paretic arm is then calculated.
Activity time ratio Baseline The activity time is the sum of the seconds of arm activity for each arm. The ratio between the paretic and the non-paretic arm is then calculated.
Number of functional movements performed with the upper limbs (FuncUse30) Baseline The functional movements are the movements with an amplitude greater than 30° within a spatial range of -30° to +30° around the horizontal, measured over a two-second time window (FuncUse30)
