How will I, and my caregivers, learn to use the #GaitHarnessSystem? Learning to use the GHS is a very simple, straightforward process, which will take you and your caregiver only minutes to learn. Immediately after purchase, and before you receive your GHS, you will be shipped a short training DVD, which outlines everything you and your caregivers will need to know about how to use the GHS. You always have access to clinical support at any time, and without limitation.
