Molecular Markers of Neuroplasticity During Exercise in People With Incomplete Spinal Cord Injury

The purpose of this study is to determine whether exercising (walking) at different intensities increases levels of factors in the blood and saliva that are known to impact neuroplasticity (how the connections in the spinal cord and brain can change) and if these levels are changed by pairing exercise with a single dose of commonly used prescription drugs or by your mood.
