Eligibility

Age

18 Years to 99 Years

Inclusion criteria

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

Exclusion criteria: - Pain in the upper extremity or shoulder, either in rest or during movements. - Orthopedic or rheumatologic ailments, which might constrain the mobility and/or force of the arm. - Additional neurological diseases. - Inability to understand and/or to follow the instructions given.

Design outcomes

Primary

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

Secondary

Measure	Time frame
Apart from the primary outcome, the relation between motor functioning (measured with the Fugl-Meyer test and kinematics) and extracted synergies will be considered in the stroke population.	—
