Detailed Description
This study aims to develop and test an innovative protocol for recovery of wrist extension after stroke, using a combination of rtfMRI, rtfNIRS, FES, and motor learning.
Aim I. Test the innovative coordination training protocol of combination rtfMRI/rtfNIRS central neural feedback and peripherally-directed, neurally-triggered FES-assisted coordination practice implemented within a framework of motor learning principles.
Hypothesis 1. Chronic stroke survivors will show significant improvement in upper limb function in response to the combined rtfMRI/rtfNIRS central neural feedback; peripherally-directed FES-assisted coordination practice of wrist and finger extension; and whole arm/hand motor learning (Primary measure: Pre-/post-treatment change score in Arm Motor Abilities Test - function domain (AMAT - F); secondary measure: Pre/post-treatment change score in Fugl-Meyer upper limb coordination.

Intervention / Treatment |
---|---|
Experimental: Stroke Group
Intervention: Stroke subjects will receive neural feedback plus FES and motor learning intervention that spans 3 phases and up to a total of 60 sessions. Phase I: real-time fMRI neural feedback training; Phase II: rtfNIRS-based neural feedback learning (built upon self-regulation strategies learned in Phase I and also assisted by neurally-triggered, peripherally-directed FES motor practice of wrist and finger extension); Phase III: motor learning minus neural feedback for an additional sessions up to 60 total; Phase IV: follow-up testing at 3 months after-treatment ends |
We are not testing the feasibility of the imaging methods; that has been well established and is used clinically.
We are testing the feasibility of using neural feedback clinical imaging methods in a neural feedback paradigm which involves sequential rtfMRI (phase I) and rtfNIRS (phase II) training; Neurally-triggered, peripherally-directed FES-assist practice of wrist and finger extension will be combined with rtfNIRS training in Phase II; up to 60 total sessions, including additional motor learning sessions without brain neural feedback will be provided in Phase III.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Arm Motor Abilities Test Functional Domain (AMAT - F)
Time Frame: change score from baseline to post-treatment; approximately 3 months.
|
AMAT-F is a measure of 13 complex, coordinated tasks used in everyday living: functional normality of movement during the 13 tasks. Minimum clinically important difference (MCID) is 0.44 change score. AMAT-F : Arm Motor Abilities Test, functional domain. minimum = 0 points. maximum = 5 points. 5 points is normal function. |
change score from baseline to post-treatment; approximately 3 months.

Measure Description |
Time Frame |
---|---|---|
Change Score From Baseline to Post Treatment for the Fugl Meyer Coordination Scale
Time Frame: from baseline to post-treatment, approximately 3 months
|
FM: Fugl-Meyer Coordination Scale: arm/hand coordination of isolated joint movement. The minimum clinically important difference (MCID) is 4.25 points. FM: 0 points, no movement; 66 points, normal coordination throughout the upper limb. |
from baseline to post-treatment, approximately 3 months
