Clinical Trial Summary

This study is being done to see how errors lead to improvement. Specifically, we are evaluating the errors stroke participants make during an upper extremity exercise program when reaching for a target using their affected arm. Once we understand the participant's reaching errors, we plan to create a customized reaching exercise according to the individual's specific error tendencies which will lead to better performance on movement ability after training.


Description:

The neuroplasticity of motor re-learning is a key pathway for recovery in neurorehabilitation. One critical challenge to devising treatment plans for motor recovery is the wide variation that exists between individuals, across movement repetitions, and even within movements. Development of a learning model that looks at these factors would better relate diagnoses to treatments, providing personalization and efficiency to therapy. This proposal aims to advance rehabilitation by building a modeling framework that explores the trends and exploits a fundamental learning process - error. Our goal is to preliminarily test the direct effect of this new treatment in preparation for the randomized controlled study to come. Understanding how error leads to better performance will help us program future devices for therapy for optimal outcomes. We are using research lab equipment at the Shirley Ryan AbilityLab (SRALab) Hospital's Robotics group. The equipment will be used to implement the reaching exercises and measure participant movement. The equipment includes: 1. Barret b.u.r.t. arm robot with Teneo forearm attachment 2. LookingGlass virtual reality display system 3. Garmin Venu Sq fitness tracking wristwatch Study Outline: Week 1, Visit 1: Consent, In-Person Screening, and Baseline Evaluations Participants will sign a consent form. Then, they will undergo a screening process to check if they meet all the eligibility requirements. Participants that pass the in-person screening and agree to continue with the study will complete baseline evaluations which will consistent of upper extremity outcome measures, and a preliminary reaching experiment on the b.u.r.t. robotic arm. Weeks 2-3, Visits 2-7: Treatment Visits In the following two weeks, participants will come to the lab three times a week. They will use the robotic arm, and complete several rounds of reaching exercises while looking in the virtual reality display system. Depending on the treatment visit, participants will either take home a fitness tracker, or be asked to return it. Week 4, Visit 8: Post-Evaluations About a week after the treatment sessions, participants will return to the lab and complete the same evaluations they completed during visit 1 to see if there is any change. Weeks 5-8: There will be no lab visits during this time. Week 9, Visit 9: About 5-6 weeks after the treatment visits, participants will come back for follow-up evaluations. These will be the same outcome measures completed during the baseline and post-evaluation sessions.
