Augmented Visual Feedback for Stroke Rehabilitation
Trial Summary
Will I have to stop taking my current medications?
The trial protocol does not specify whether you need to stop taking your current medications. However, if you have had Botox injections in the affected arm within the past 4 months, you would not be eligible to participate.
What data supports the effectiveness of the treatment Augmented Visual Feedback for Stroke Rehabilitation?
Is augmented visual feedback safe for use in stroke rehabilitation?
How does the treatment 'Augmented Visual Feedback for Stroke Rehabilitation' differ from other treatments for stroke rehabilitation?
This treatment is unique because it uses augmented visual feedback, including virtual reality and visual biofeedback, to enhance motor learning and motivation in stroke rehabilitation. Unlike traditional methods, it provides real-time visual cues to correct movement errors, potentially improving motor performance without the need for expensive robotic devices.12457
What is the purpose of this trial?
The goal of this research study is to increase understanding of error augmentation by applying it to visual feedback during motion tracking with a Leap Motion device - a recently developed optical hand tracking tool - and the LookingGlass - a new, portable virtual reality environment.In conjunction with the Leap, large, three dimensional work spaces can provide an immersive and virtual augmented environment for rehabilitation. Previously, experiments have utilized the Virtual Reality Robotic and Optical Operations Machine (VRROOM) to create such visually immersive environments. The Robotics lab as part of the Arms and Hands Lab on the 22nd floor of the Shirley Ryan Abilitylab has developed a portable version of this system, which is more compact and clinic-compatible. Combining this visual 3D system with the Leap creates a novel, more capable apparatus for studying error augmentation.This research study will have 3 different arms: 1.) a healthy group of individuals (Healthy Arm), 2.) a group of stroke survivors within 8 months of stroke (Acute Arm), and 3.) a group of stroke survivors that had their stroke more than 8 months ago (Chronic Arm).Each Arm will use the Leap motion tracker and the Looking Glass to participate in a reaching intervention. The healthy arm will only participate in 1 visit with an intervention with and without error augmented visual feedback. The Acute Arm and the Chronic Arm will both have 2 groups: 1.) Error Augmented Visual Feedback group and 2.) Non-Augmented or Veridical Visual Feedback group.The Chronic Arm will have a structured intervention and evaluation protocol: Study staff will administer outcome assessments at 3 time points: a.) prior to intervention, b.) post intervention, and c.) 2 months after the conclusion of intervention. Intervention will occur over the span of 6-8 weeks with the goal of 3 1-hour sessions per week.The Acute Arm will have a less structured intervention that will occur while the participant is an inpatient at Shirley Ryan AbilityLab. Study staff will administer outcome assessments at at least 2 time points: a.) prior to intervention, b.) post intervention just prior to discharge from Shirley Ryan AbilityLab. Between initial and post intervention evaluations, midpoint evaluations will take place at a maximum of once per week if the participant's schedule, activity tolerance, and length of stay allows. Intervention will consist of 1-hour sessions occurring according to the availability of the participant at the rate of no more than 2 sessions in a 24 hour period.Investigators hope to investigate these questions:1. Can the movement of healthy individuals be characterized with error augmented visual feedback and veridical visual feedback?2. Will error augmented visual feedback or veridical visual feedback result in greater movement ability improvement? Investigators hypothesize that in the Chronic Arm, those what trained with error-augmented visual feedback will have improved movement ability compared to those who trained with veridical visual feedback.3. Is treatment with the looking glass and leap system feasible with an inpatient population?Investigators hypothesize that this treatment will be feasible for an inpatient population.

Eligibility Criteria
This trial is for adults who had a stroke at least 8 months ago, can move their shoulder and elbow against gravity to reach forward, but not for those with severe muscle stiffness, recent Botox in the arm, or other rehab treatments. It excludes pregnant women, children, prisoners, people with multiple strokes or severe sensory issues in the limb.Inclusion Criteria

Timeline
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants engage in reaching interventions using the Leap motion tracker and Looking Glass system. The Chronic Arm undergoes structured sessions over 6-8 weeks, while the Acute Arm has less structured sessions during inpatient stay.
Follow-up
Participants are monitored for changes in movement ability and arm test scores after treatment. Chronic Arm follow-up occurs 2 months post-intervention.
