Description
Inclusion Criteria:
- 6 to 24 months since a first clinical cortical or subcortical, hemorrhagic or nonhemorrhagic stroke
- unilateral upper limb hemiparesis with finger extensor strength of grade no more than 4 out of 5 on the Medical Research Council (MRC) scale
- score of at least 1 and no more than 11 out of 14 on the hand section of the upper extremity Fugl-Meyer Assessment
- adequate active movement of the shoulder and elbow to position the hand in the workspace for table-top task practice (necessary for the lab task practice sessions)
- able to follow 3-stage commands
- able to recall at least 2 of a list of 3 items after 30 minutes
- skin intact on the hemiparetic arm
- surface stimulation of the paretic finger and thumb extensors produces functional hand opening without pain (this will exclude those who have too much flexor spasticity)
- able to hear and respond to cues from stimulator
- not receiving occupational therapy (no concomitant OT)
- full voluntary opening/closing of the contralateral (less affected) hand
- demonstrates ability to follow instructions for operating the stimulator or have a caregiver who will assist them
Exclusion Criteria:
- co-existing neurologic diagnosis of peripheral nerve injury, Parkinson's disease, spinal cord injury, traumatic brain injury, or multiple sclerosis
- uncontrolled seizure disorder
- brainstem stroke
- uncompensated hemineglect
- severe shoulder or hand pain
- insensate forearm or hand
- history of potentially fatal cardiac arrhythmias with hemodynamic instability
- implanted electronic systems (e.g. pacemaker)
- botulinum toxin injections to any upper extremity muscle within 3 months of enrolling
- pregnant women due to unknown risks of surface NMES during pregnancy
- lack of functional passive range of motion of the wrist or fingers of affected side
- diagnosis (apart from stroke) that substantially affects paretic arm and hand function
- deficits in communication that interfere with reasonable study participation
- lacking sufficient visual acuity to see the stimulator's display
- concurrent enrollment in another investigational study

Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Experimental: CCFES
Contralaterally Controlled Functional Electrical Stimulation (CCFES) uses an electrical stimulator and surface electrodes placed over the paretic finger and thumb extensors to deliver stimulation with an intensity that is proportional to the degree of opening of the contralateral unimpaired hand wearing an instrumented glove.
Thus, volitional opening of the nonparetic hand produces stimulated opening of the paretic hand.
During the lab visits, participants in the CCFES group will use CCFES to assist hand opening during occupational therapy task practice.
During their home sessions, participants in the CCFES group will use CCFES to perform hand opening exercise.
|
An electrical stimulator will be used to deliver electrical current through surface electrodes to produce hand opening by making the paretic finger and thumb extensor muscles contract.
The stimulator can be programmed to turn on and off in a repetitive cyclic fashion (i.e., cNMES) or be programmed to deliver stimulation with an intensity that corresponds to the opening of a glove instrumented with sensors and plugged into the stimulator (i.e., CCFES).
Task practice that requires movement and use of the paretic hand under the guidance of a trained therapist.
|
|
Active Comparator: cNMES
Cyclic Neuromuscular Electrical Stimulation (cNMES) uses an electrical stimulator and surface electrodes over the paretic finger and thumb extensors to deliver electrical stimulation to open the weak hand.
The stimulation automatically turns on and off causing the weak hand to open repetitively for several seconds at a time.
During the lab visits, participants in the cNMES group will receive occupational therapy task practice.
During their home sessions, participants in the cNMES group will use cNMES to perform hand opening exercise.

Active Comparator: Task Oriented Therapy
Task Oriented Therapy (TOT) focuses on practicing using the weak hand to practice activities of daily living tasks.
During the clinic visits, participants in the TOT group will receive occupational therapy task practice.
During their home sessions, participants in the TOT group will practice using their hand to complete a list of tasks given to them by the therapist to ensure that the participant receives a high dose of task practice.

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Change in Box and Blocks Test (BBT) at 6 Months Post-Treatment
Time Frame: Baseline to 6 months post-treatment
|
The BBT is a measure of hand dexterity.
It is a count of how many blocks a patient can pick up, move over a barrier, and release in 60 seconds.
The higher the score, the better the motor recovery.

Measure Description |
Time Frame |
|---|---|---|
|
Change in Upper Extremity Fugl Meyer (UEFM) at 6 Months Post-Treatment
Time Frame: Baseline to 6 months post-treatment
|
The UEFM is a measure of upper limb motor impairment with a minimum score of 0 and maximum score of 66.
The higher the score, the better the motor recovery.
|
Baseline to 6 months post-treatment
|
|
Change in Action Research Arm Test (ARAT) at 6 Months Post-Treatment
Time Frame: Baseline to 6 months post-treatment
|
The ARAT is a measure of arm and hand function with a minimum score of 0 and maximum score of 57.
The higher the score, the better the motor recovery.
|
Baseline to 6 months post-treatment
|
|
Change in Stroke Upper Limb Capacity Scale (SULCS) at 6 Months Post-Treatment
Time Frame: Baseline to 6 months post-treatment
|
The SULCS is a measure of upper limb capacity with a minimum score of 0 and maximum score of 10.
The higher the score, the better the motor recovery.
