The investigators aim to test whether intensive training of finger individuation during the sensitive window of the subacute phases can lead to a clinically-meaningful recovery of dexterous movement in stroke patients.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intervention | Experimental | The patient hand will be restrained to a robotic arm AMADEO(TM) which enables the measurement and manipulation of forces at each finger individually. After appropriate calibration, the force measurements obtained from the robot will be used to move a cursor on the screen. The patient will be rewarded visually and auditory when a higher degree of finger individuation will be measured. Specifically, when the applied force of the instructed fingers hit the predefined force target and at the same, the force in the non-instructed fingers stay as low as possible |

| Control | Sham Comparator | The patient hand will be restrained to a robotic arm AMADEO(TM) which enables the measurement and manipulation of forces at each finger individually. After appropriate calibration, the force measurements obtained from the robot will be used to move a cursor on the screen. The patient will be rewarded in a way that is unrelated to the degree of individuation. In other words, a successful trial considered when the applied force of the instructed fingers hits the predefined force target regardless of the force exerted in the non-instructed fingers. |

|---|---|---|---|---|
| Intensive Finger Individuation Therapy | Combination Product | Interactive robot-mediated treatment aimed at increased individuation done repeatedly for at least1 hour per day for 2 weeks (5 training days a week). |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Fugl-Meyer Assessment Score for Upper Extremity at the immediate post-intervention time | A Likert-scale that quantifies movement quality, sensation, range of motion and pain in the upper limb following stroke. Range: 0 - 66. Higher values correlate with better motor control. | Change from Baseline Score at 1-3 days post-intervention |
| Change in Fugl-Meyer Assessment Score for Upper Extermity at 1-month post-intervention | A Likert-scale that quantifies movement quality, sensation, range of motion and pain in the upper limb following stroke. Range: 0 - 66. Higher values correlate with better motor control. | Change from Baseline Score at 1 month post-intervention |
| Change in Fugl-Meyer Assessment Score for Upper Extermity at 3-month post-intervention | A Likert-scale that quantifies movement quality, sensation, range of motion and pain in the upper limb following stroke. Range: 0 - 66. Higher values correlate with better motor control. | Change from Baseline Score at 3 month post-intervention |
| Change in Individuation Index at the immediate post-intervention time | The relationship between forces (in Newton) in the active vs. passive fingers during a set of isolated finger movements. Higher numbers correlate with better finger-joint individuation, thus better dexterity. | Change from Baseline Score at 1-3 days post-intervention |
| Change in Individuation Index at 1-month post-intervention | The relationship between forces (in Newton) in the active vs. passive fingers during a set of isolated finger movements. Higher numbers correlate with better finger-joint individuation, thus better dexterity. | Change from Baseline Score at 1-month post-intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Arm Research Action Test (ARAT) Score at the immediate post-intervention time | Time and quality of performance of 19 items mimicking activity of daily living, are measured. Tange: 0 - 57. Higher values correlate with better motor control. | Change from Baseline Score at 1-3 days post-intervention |
| Arm Research Action Test (ARAT) Score at at 1-month post-intervention |

| Change in Individuation Index at 3-month post-intervention | The relationship between forces (in Newton) in the active vs. passive fingers during a set of isolated finger movements. Higher numbers correlate with better finger-joint individuation, thus better dexterity. | Change from Baseline Score at 3-month post-intervention |

| Change in M1 MEP (motor evoked potentials) amplitude at immediate post-intervention time | Stimulation of the ipsilesional M1 will be done (using either figure-of-eight, H- or dual-H rotational field coil) connected to TMS to elicit motor-evoked potential (MEP) of the first dorsal interosseous (FDI) muscle of the right hand, recorded with an EMG electrode. The peak-to-peak time will be computed off-line using MATLAB software. Higher MEP amplitudes correlate with higher cortico-spinal integrity. | Change from Baseline Score at 1-3 days post-intervention |

| Change in extent of SICI (short-interval cortical inhibition) at the immediate post-intervention time | Single test pulses, conditioning pulses (five of each) and paired pulses (five pairs) at an inter-stimuli-interval (ISI) of 2 ms will be delivered to the motor cortex of both hemispheres. The intensity of the conditioning stimulus will be set at 80% of the subject's resting motor threshold (MT). The intensity of the test pulse will be 110% of the resting MT. The SICI will be measured as the reduction in conditioned MEPs relative to baseline MEPs. Higher SICI correlates with increased inhibitory activity of the motor cortex. | Change from Baseline Score at 1-3 days post-intervention |
