Brief summary

The research team will develop a novel training tool to improve finger joint coordination, to address the unmet need in the current rehabilitation, thereby enhancing hand function and contributing to improved independence and quality of life for Veterans with stroke.

Detailed description

The research team will determine feasibility of training using CA and TA controllers in subacute stroke. Specifically, we will examine if joint coordination improves over a training session. The investigators will compare the extent of improvement for each controller and impairment severity.

Interventions

DEVICEExoskeleton

Participants will receive assistance to move finger joints away from the compensatory coordination (compensation avoidance), toward the desired trajectories (task assistance), both, and none in different days.

Inclusion criteria

* Adult Veterans with a stroke 1-6 months ago * Ability to move fingers (Chedoke-McMaster Hand Section Stage 2-4)

Exclusion criteria

* Inability to follow 2-step commands * Severe muscle tone prohibiting proper placement of the fingers (Modified Ashworth Scale, MAS=5 out of 5) * Change in spasticity medication or botulinum toxin injection in the upper limb within 3 months prior to or during enrollment

Design outcomes

Primary

Measure	Time frame	Description
change in finger joint torque assistance	from the 1st half to the 2nd half of the 1-hour training session	Change in finger joint torque assistance needed from the 1st half to the 2nd half of the 1-hour training session. Reduction in torque is considered a good outcome. There is no predefined minimum/maximum.
