Robotically Augmented Mental Practice for Neuromotor Facilitation
In Brief
A clinical study evaluating Visual motor imagery (MI), Kinesthetic MI, and 5 other interventions for Stroke. Completed, enrolled 25 participants across 1 site.
Detailed Summary
This project will develop and test a new paradigm of motor imagery for facilitating neuromotor excitability and performance of distal muscles in the upper limb by adopting a robotic prosthesis and integrating proven procedures for neuromotor facilitation. The scientific purpose of the study is to understand the effect of controlling a detached robotic prosthesis with proximal muscle activation on brain excitability of the resting arm muscles as well as reaction time. The efficacy of this task will be understood by comparing with other task conditions (motor imagery only, 2D visual feedback on a monitor, etc.) that do not involve the robotic prosthesis. The test of the developed system will be performed in healthy able-bodied adults. The feasibility of the system will be examined in post-stroke adults.
Study Details
Timeline
Interventions
Subjects will relax their muscles and perform conventional visual motor imagery (MI). With the guidance of audio instruction, the subjects will imagine the grasp and release motions with the right arm for 2 s in each motion in their mind. There will be no proximal muscle contraction.
The same MI procedure as Visual MI will be performed, except that the subjects will focus on the kinesthetic sensation that they would feel with the imagined motions.
Subjects will perform robotically augmented mental practice for grasp and release motions with the activation control of the proximal muscles. During this task, subjects will also imagine the kinesthetic sensation that they would feel with the corresponding motions with the right arm.
Subjects will perform the Robot-Hand Interaction without MI.
Subjects will interact with visual feedback of virtual robot actions on a monitor.
Subjects will relax their muscles and focus on observing the computer-controlled grasp and release actions of the robotic hand.
Subjects will rest without a task.
