Clinical Trial

Robotic Interventions For Spasticity Treatment

IRB Protocol Number STU00213328

GRACE HOO ghoo@sralab.org

Objective

The Shirley Ryan AbilityLab is seeking individuals post-stroke to study the benefits of receiving visual and physical feedback during ankle exercises to improve movement and reduce stiffness caused by spasticity.

This study involves using an ankle robot to deliver treatments to target spasticity. Participants will wear the robot on their weaker foot and move their ankle while sitting.

Participants will be randomized into one of three training groups:

  1. Continuous passive movement (CPM) – The ankle robot will move your foot up and down.
  2. Visual feedback – You will play a video game and control a character on the screen based on your ankle muscle contractions and ankle position.
  3. Visual and haptic feedback – You will play a video game and control a character on the screen based on your ankle muscle contractions and ankle position. The ankle robot will provide physical feedback based on your muscle contractions.

Participants will complete a training program (3 sessions a a week for 4 weeks, as well as some assessment/follow-up visits).

Who Can Participate

Participants must meet the following criteria:

  • English speaking adults
  • Ages 18-80 years
  • Individuals diagnosed with stroke at least 3 months prior
  • Available to come to the downtown AbilityLab for up to 15 visits, as well as 1-month and 3-month follow-up visits
  • Ability to move affected or weaker foot at the ankle
  • Spasticity (stiffness) at the ankle
  • Can walk independently with or without assistive device for 30 feet (10 meters) or more

Compensation

Participants will be compensated $30-40 per visit for their time and effort. Parking in the Shirley Ryan AbilityLab garage is covered.

Age Range

18-80
