Target Recruitment: 25

Inclusion Criteria

- At least 6 months post-stroke.
- The function of the right arm is affected.
- Able to lift the right arm against gravity and perform a horizontal and vertical reaching movement.
- Able to decide whether to participate or not and to sign an informed consent.

Exclusion Criteria

Primary Outcome Measures

Name	Time	Method
<p>In the current study, patterns of muscle activity (measured with<br /><br>electromyography (EMG)) and kinematics (measured with an instrumented<br /><br>exoskeleton) during reaching movements in non-affected persons and stroke<br /><br>patients are considered. Muscle synergies will be extracted from the recorded<br /><br>EMG data, with accompanying time onset and amplitude parameters. We are<br /><br>interested in the difference in amount of synergies between both groups, the<br /><br>muscles included in the synergies and the accompanying parameters. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Apart from the primary outcome, the relation between motor functioning<br /><br>(measured with the Fugl-Meyer test and kinematics) and extracted synergies will<br /><br>be considered in the stroke population.</p><br>
