Stroke, Acute, Stroke, Hemiparesis
About this trial
This is an interventional treatment trial for Stroke, Acute focused on measuring hand, stroke, hemiplegia, electrical stimulation, recovery
Eligibility Criteria
Inclusion Criteria:
- Age 18 to 80
- Within 6 months of first clinical hemorrhagic or nonhemorrhagic stroke
- Cortical or subcortical stroke
- Unilateral upper extremity hemiparesis with severe finger extensor and flexor paresis (<= grade 4 on Medical Research Council (MRC) scale)
- Adequate movement of the shoulder and elbow to allow volitional positioning of the affected hand in the workspace.
- Surface NMES of finger and thumb extensors produces functional hand opening without pain
- Full volitional opening of the contralateral hand of the unimpaired side.
- Able to follow 3 stage commands
- Able to remember at least 2 of 3 items after 30 minutes
- Able to hear and respond (by opening the less affected hand) to auditory cues issued from the stimulator?
- Caregiver available and willing to help assist with the device and home regimen and ensure compliance
- Skin intact on hemiparetic arm
- Medically stable
Exclusion Criteria:

- Ipsilateral lower motor neuron lesion
- Parkinson's Disease
- Spinal cord injury
- Traumatic brain injury
- Multiple sclerosis
- Lack of functional passive range of motion of the wrist or fingers of affected side
- Severe shoulder or hand pain (unable to volitionally position hand in the workspace without pain)
- Intramuscular botulinum toxin injections in upper extremity muscle in the last 3 months

Experimental
Active Comparator
CCFES
cNMES
CCFES - Contralaterally Controlled Functional Electrical Stimulation Stimulation to finger and thumb extensors and flexors only in response to and with an intensity proportional to opening and closing of the contralateral unimpaired hand A glove instrumented with sensors and worn on the unimpaired hand detects the degree of hand opening and determines stimulation intensity Therapy sessions are done with the subject being assisted by the CCFES system.
cNMES - Cyclic NeuroMuscular Electrical Stimulation. Preprogrammed cycles of finger and thumb flexor and extensor stimulation repeatedly and automatically close and open the hand without any effort or voluntary intent required by the subject. Subject instructed to relax, not attempt to assist the stimulation, and not to move the contralateral arm/hand during stimulation Therapy sessions are done without the stimulation system
