TENS Trial to Prevent Neuropathic Pain in SCI

The purpose of this research study is to: 1) test whether transcutaneous electrical nerve stimulation (TENS) after spinal cord injury can reduce the onset of post-injury neuropathic pain; and 2) to learn more about this kind of pain and who is at risk for suffering from this type of pain after spinal cord injury. Neuropathic pain is a type of pain that occurs in about 50% of people with spinal cord injury. This type of pain is usually described as "burning" or "tingling," and is present around the level of injury and/or in areas below the level of injury. The investigators' goal is to try a non-drug treatment (TENS) that may help prevent this pain from occurring. Pain symptoms will be compared between the study participants who receive active TENS and the study participants who receive a sham TENS treatment.
