Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Ongoing research (NCT02098265) suggests that noninvasive EEG driven Brain Computer Interface (BCI) systems hold the potential for facilitating recovery in the chronic phase after stroke by synchronizing central or brain activity with peripheral movements and thereby harnessing brain plasticity.

The specific aims of this study are:

Aim 1: To investigate the efficacy of active FES vs. passive FES, as measured by changes in behavioral measures. The investigators hypothesize that improvements in motor function will be significantly greater using the active FES therapy than the passive FES therapy.

Aim 2: To investigate the relationship between brain functional activation patterns and behavior changes induced by active vs. passive FES intervention. The investigators hypothesize that changes induced by active FES (as measured by brain fMRI and EEG measures) will show greater adaptive brain reorganization changes (i.e. brain changes that correlate with improved outcomes) than that induced by the passive FES.

Aim 3: To investigate the relationship between brain white matter integrity and behavior changes induced by active vs. passive FES intervention. The investigators hypothesize that changes induced by active FES (as measured by brain DTI measures) will show greater adaptive brain reorganization changes (i.e. brain changes that correlate with improved outcomes) than that induced by the passive FES.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Passive FES

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.

Group Type ACTIVE_COMPARATOR

Behavioral Assessments

Intervention Type BEHAVIORAL

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

Magnetic Resonance Imaging

Intervention Type OTHER

A functional magnetic resonance image will be collected.

Functional Electric Stimulation (FES)

Intervention Type DEVICE

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 FES

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.

Group Type EXPERIMENTAL

Behavioral Assessments

Intervention Type BEHAVIORAL

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

Magnetic Resonance Imaging

Intervention Type OTHER

A functional magnetic resonance image will be collected.

EEG

Intervention Type OTHER

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.

Functional Electric Stimulation (FES)

Intervention Type DEVICE

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.
