Study Stopped
We only enrolled one participant, and this participant was withdrawn prior to collecting any useful data. Then, COVID. Now, Dr. Collinger's faculty tenure with the VA ended.

Brief Summary
This is a pilot study to collect data to support a VA grant submission to study fMRI and neurophysiological predictors of hand function and recovery during a robotic intervention in people with hand impairments due to stroke or spinal cord injury.

Outcome Measures
Primary Outcomes (1)
Number of participants that show significant finger-specific activation prior to the intervention
The investigators will use functional magnetic resonance imaging (fMRI) to measure cortical activity relating to finger-specific brain activation before the rehabilitation intervention.
Baseline, prior to intervention, week 1
Secondary Outcomes (2)
Change from baseline finger strength after rehabilitation intervention
After intervention, 12 weeks
Change from baseline in finger dexterity after rehabilitation intervention
After intervention, 12 weeks
Study Arms (1)
Hand impairment due to stroke or spinal cord injury
EXPERIMENTALIndividuals who have experienced a sub-cortical stroke or a cervical spinal cord injury resulting in loss of hand function.
Interventions
Individuals with hand impairment due to stroke or spinal cord injury will wear a motorized glove (Gloreha Sinfonia), or exoskeleton, as part of a rehabilitation protocol to improve dexterity. For each exercise, participants will attempt to do the action, receiving assistance as necessary via powered motors that can move each finger through its passive range of motion based on the current and target position.
All participants will undergo 3 functional MRI's (fMRI's), two at the beginning of the experiment to document brain activity related to movement intention and ability to sense movement. A third MRI will be performed after the rehabilitation is completed to document the change in brain activity related to movement intention and ability to sense movement.
Stimulation of the nervous system may be performed using a magnetic stimulator. TMS of the central nervous system is optional. Whether or not a participant undergoes TMS will depend upon their consent, their eligibility for TMS (i.e. no seizure history), and their neurological response to TMS.
Eligibility Criteria
You may qualify if:
- Normal or corrected to normal vision
- Hand impairment due to spinal cord injury or stroke
- Weakness of fingers
- One year after stroke or spinal cord injury
- Some proprioception (can feel when finger is moved, without seeing)
- Minimal spasticity
You may not qualify if:
- Implanted metal with is unsafe for MRI
- Pregnant or expecting to become pregnant
- History of hand surgery which is under evaluation
- Cognitive or language issues that would interfere with following directions
- Other neurological disorder that would affect movement
- History of seizure or epilepsy
- Body weight \> 300 pounds
