NCT04141774

Brief Summary

The purpose of this research is to determine if functional muscle stimulation, directed by electroencephalogram (EEG) output, can increase the extent of stroke recovery on behavioral measures and induce brain plasticity as measured by functional magnetic resonance imaging (fMRI). Participants will include stroke patients with upper-limb hemiparesis and can expect to be on study for approximately 4 months.

Outcome Measures

Primary Outcomes (2)

  • Action Research Arm Test Scores

    The Action Research Arm Test (ARAT) is designed for evaluation of upper extremity function. This test consists of sections for Grasp, Grip, Pinch and Gross Movements and comprise a total of 19 tests. Each test is scored 0-3 where 0 is 'no movement' and 3 is 'the movement is performed normally'. Each section is scored separately and the scores added for a total possible range of scores from 0-57 where the higher the score, the complete and efficient the movement. Scores will be reported for baseline, mid (\~7 weeks), post (\~10 weeks), and end of study, up to 4 months.

    baseline, 7 weeks, 10 weeks, 4 months

  • Stroke Impact Scale

    The Stroke Impact Scale, or SIS, was created to assess changes in impairments, activities and participation following a stroke. Scores on the SIS will provide an index of clinically "meaningful" change representing the change in the patient's mental and physical abilities concurrent with their performance on the verbal fluency and memory tasks. The 4 physical function domains (strength, hand function, activities of daily living (ADL)/instrumental activities of daily living (IADL), and mobility) will be collapsed to a physical function subscale. All domain scores range from 0 to 100 with 100 being the best.

    baseline, 7 weeks, 10 weeks, 4 months

Secondary Outcomes (8)

  • Change in Electroencephalogram (EEG) Response Strength

    baseline 1, baseline 2, 7 weeks, 10 weeks, 4 months

  • Signal Change in Functional Magnetic Resonance Imaging (MRI)

    baseline 1, baseline 2, 7 weeks, 10 weeks, 4 months

  • Nine Hole Peg Test (9HPT)

    baseline 1, baseline 2, 7 weeks, 10 weeks, 4 months

  • Motor Activity Log (MAL): Amount of Use

    baseline 1, baseline 2, 7 weeks, 10 weeks, 4 months

  • Motor Activity Log (MAL): Quality of Movement

    baseline 1, baseline 2, 7 weeks, 10 weeks, 4 months

  • +3 more secondary outcomes

Study Arms (2)

Passive FES

ACTIVE COMPARATOR

Subjects randomized to this control group will be asked to participate in a passive FES intervention or non-EEG guided muscle stimulation. Participation will include behavioral assessments, functional magnetic resonance imaging, and functional electric stimulation (FES) treatment.

Device: Functional Electric Stimulation (FES)Behavioral: Behavioral AssessmentsOther: Magnetic Resonance Imaging

Active FES

EXPERIMENTAL

Subjects randomized to this experimental group will be asked to complete the active FES intervention which include EEG guided muscle stimulation. Participation will include behavioral assessments, functional magnetic resonance imaging, functional electric stimulation (FES) treatment, and EEG.

Device: Functional Electric Stimulation (FES)Behavioral: Behavioral AssessmentsOther: Magnetic Resonance ImagingOther: EEG

Interventions

FES uses low energy electrical pulses to artificially generate body movements in individuals with muscle paralysis. FES can be used to generate muscle contraction in otherwise paralyzed limbs to restore function.

Active FESPassive FES

These assessments will include measures of upper extremity motor assessments, standard stroke scales, and measures of activities of daily living.

Active FESPassive FES

A functional magnetic resonance image will be collected.

Active FESPassive FES
EEGOTHER

EEG electrodes will be attached to the subject's scalp using a standard, commercially available electrode cap. Proper electrode placement is made according to the international 10-20 system, ensuring complete electrode coverage over sensorimotor cortex.
