About

The purpose of this study is to determine if playing a virtual reality walking game can help improve neuropathic pain in adults with chronic spinal cord injury.

Full description

Many people with SCI experience neuropathic pain. Neuropathic pain is often described as sharp, burning, or electric. 'Traditional' treatments often do not do a good job of reducing neuropathic pain. Therefore, it is important to see if 'non-traditional' treatments might work. Scientists think that neuropathic pain occurs in SCI because the sensations coming from the eyes and up the spinal cord to the brain do not match what the brain thinks it told the body to do. This 'mis-match' may result in changes in the brain that make neuropathic pain possible. Virtual reality walking reduces this 'mis-match.' It does this by creating the 'illusion' that the person is walking. The brain then thinks it is telling the body to walk AND the information coming from the eyes matches its instructions. This 'matching' may reverse the brain changes that made neuropathic pain possible. The current study is specifically focused on individuals whose SCI has been classified as complete (ASIA A).

4. Must be more than one year post-injury to begin study (can be screened at an earlier time for eligibility)
5. Must have mobile connectivity with usable service
6. Must be stable on pain medication for 1 or more months
7. Must be cleared on the VRWalk physical activity clearance scale
8. Must not have motion sickness that interferes with daily life
