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.
Interventions
BEHAVIORALObjective assessment of upper limb use during activities in ecological situation
Twenty-five patients will be recorded performing three activities during their rehabilitation: getting dressed, preparing a meal, and eating a meal. The movements of their upper limbs will be tracked using wrist-worn accelerometers and video cameras.

Intervention model description
While patients are in rehabilitation, upper limb movements will be recorded using wrist-worn accelerometers and video cameras, during dressing, meal preparation, and meal-taking activities.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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) |
| 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. |
