Eligibility
Inclusion criteria
Inclusion criteria: 1. A history of a single unilateral stroke in the medial cerebral artery (MCA) region resulting in single-sided hemiparesis; 2. The onset of the stroke was more than six weeks ago; 3. The ability to voluntarily generate 20 degrees excursions in the plane of elevation (horizontal ab-/adduction) and elevation angle (ab-/adduction, ante-/retroflexion) of the shoulder joint; 4. The ability to voluntarily generate an excursion of 20 degrees of elbow flexion/extension; 5. The ability to voluntarily extend the wrist 10 degrees from neutral flexion/extension; 6. Adequate cognitive function to understand the experiments, follow instructions, and give feedback to the researchers.
Exclusion criteria
Exclusion criteria: 1. A fixed contracture deformity in the (affected) upper limb was present; 2. Pain as a limiting factor for the subject's active range of motion; 3. The use of a pace-maker.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome of the present experiment is the Box and Block test which measures hand function of stroke patients. This functional measure is used to evaluate the influence of different types of electrical stimulation (EMG triggered and position triggered multichannel ES, single channel ES and none) on functional hand opening. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary study parameters are muscle activation patterns (MAP) measured with electromyography and kinematics during reach-to-grasp movements. | — |
