- Primary Outcome Measures
Name Time Method The main study parameter will be ARAT scores for the selected ARAT objects (10cm cube, 2,5 cm cube, 6mm ball bearing and 1,5 cm marble). The endpoint of the study is an effective control algorithm, which is able to assist stroke patients to successfully grasp these selected ARAT objects.
- Secondary Outcome Measures
Name Time Method Target positions for all fingers are estimated on beforehand. These target positions are used to estimate kinematic movement errors of the hand, thumb and fingers during the grasping movements. This measure is used to evaluate the influence of different types of assistance on hand, thumb and finger movement. In addition, the effect of electrical stimulation in healthy and stroke patients will be compared. During T1 and T2 forces at the target position are measured and compared to target forces needed to lift the specific ARAT objects. This measure is also used to evaluate the influence of different types of assistance on hand, thumb and finger movement. During T2 the amount of flexor activity during hand opening/closing will be measured by EMG, to assess the amount of enlarged flexor activity in the patient group, with should be counteracted by the stimulation algorithms.
