  Purpose
The long-range goal of this work is to identify how to target treatment so that the brain is functionally re-organized to produce movement. This study will compare treatment response to robotics versus functional neuromuscular stimulation.

Condition Intervention
Cerebral Stroke Cerebrovascular Accident Stroke Device: Robotics training for shoulder elbow. Device: Surface Functional Neuromuscular Stimulation Other: whole arm motor learning

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: CNS Plasticity Induced By Motor Learning Technologies Following Stroke

Primary Outcome Measures:
  • AMAT [ Time Frame: prior to treatment and following 3 months of treatment ]
    The AMAT is a measure of complex functional task performance of a variety of specified tasks and is measured in seconds summed across the various tasks. A higher score is indicative of decreased performance on the measure. A max score of 3000 seconds would indicate inability to perform any portion of the test.

  • M1 Activation Absolute Change Score [ Time Frame: at baseline and following 3 months of treatment ]
    A measure of brain activation change in the area of M1 following intervention (pre to post intervention). A number greater than 0 indicates a change in brain activation in the area of M1. The maximum voxel activation for a healthy adult in the studied region of Interest (M1) is 659.

Detailed Description:
Methods. Up to ninety-six chronic stroke subjects (> 12 months post stroke) will be randomized to one of the treatment groups: Wrist/hand Functional Electrical Stimulation (FES)+whole arm motor learning group; shoulder/elbow robotics + whole arm motor learning group; and whole arm motor learning group. For all groups, treatment will offered 5 hrs/day, 5 days/week, for 12 weeks. All three treatment groups will receive motor learning therapy. For the Wrist/hand FES+whole arm motor learning group, there will be the addition of FES during treatment. For the Shoulder/elbow robotics + whole arm motor learning group there will be the addition of robotics training. Outcome measures will be collected at weeks 1, 6, 12, and three months after the end of treatment. Measures will include muscle strength (Manual Muscle Testing); coordination of joint movement (Fugl-Meyer Coordination Scale); motor control of target acquisition, pathway maintenance; and smoothness of movement (robotics measures); performance of 13 functional tasks (Arm Motor Ability Test); and quality of life (Stroke Impact Scale). Measures of brain function will be non-invasive and will include cognitive planning time, cognitive effort level, and location of brain activity during simple shoulder and arm movements. Changes in brain function measures will reflect plasticity or adaptability in response to treatment.
