Therapies for Recovery of Hand Function After Stroke
- Conditions
- Upper Extremity ParesisHemiplegiaStroke
- Registration Number
- NCT03574623
- Lead Sponsor
- MetroHealth Medical Center
- Brief Summary
After a stroke, it is very common to lose the ability to open the affected hand. The purpose of this study is to compare the effects of three different therapies on recovery of hand function after stroke and determine if any one is better than the other.
- Detailed Description
A single-blinded randomized controlled trial will be carried out to assess and compare the effects of 12 weeks of Contralaterally Controlled Functional Electrical Stimulation (CCFES), Cyclic Neuromuscular Electrical Stimulation (cNMES), and Task Oriented Training. Dexterity, upper limb impairment, and activity limitation will be assessed at 0 (baseline), 12 (end of treatment), and 36 weeks. The treatment dose will be the same for all three groups: 10 sessions per week of self-administered treatment at home plus 2 sessions per week of group-specific occupational therapy in the lab.
Recruitment & Eligibility
- Status
- COMPLETED
- Sex
- All
- Target Recruitment
- 132
- 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
- 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

- Primary Outcome Measures
Name Time Method Box and Blocks Test (BBT) change 0 to 12 weeks, 0 to 36 weeks 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.
- Secondary Outcome Measures
Name Time Method Responder Rate 0 to 36 weeks Proportion of participants who had a gain of at least 6 points on the UEFM
Upper Extremity Fugl Meyer (UEFM) change 0 to 12 weeks, 0 to 36 weeks The UEFM is a measure of upper limb motor impairment with a maximum score of 66. The higher the score, the better the motor recovery.
Action Research Arm Test (ARAT) change 0 to 12 weeks, 0 to 36 weeks The ARAT is a measure of arm and hand function with a maximum score of 57. The higher the score, the better the motor recovery.
Stroke Upper Limb Capacity Scale (SULCS) change 0 to 12 weeks, 0 to 36 weeks The SULCS is a measure of upper limb capacity with a maximum score of 10. The higher the score, the better the motor recovery.
