This study will use a non-invasive form of spinal stimulation, called transvertebral direct current stimulation, or tvDCS. It currently is not clear what effects this type of stimulation has on the excitability of the brain and spinal cord in people with spinal cord injury. In this study, subjects will participate in 3 sessions, with at least 1 week in between sessions, during which they will get a different condition of tvDCS. We will test the excitability of the brain and spinal cord before and after tvDCS in each session.
