Brief Summary:
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.

Arm Intervention/treatment
Experimental: Active TENS
Participants are given 30 minutes of TENS therapy twice a week for 8 weeks.
Device: TENS
TENS 7000

Sham Comparator: Sham TENS
Electrodes are placed on participants for 30 minutes twice a week for 8 weeks without TENS stimulation.
Other: Sham TENS
Inactive electrodes

Primary Outcome Measures :
  1. The percentage of subjects who develop chronic neuropathic pain. [ Time Frame: 12 months ]
    as defined by a score of ≥2 on the Spinal Cord Injury Pain Inventory (SCIPI), a self-report scale of symptoms

  2. The severity of chronic neuropathic pain [ Time Frame: 12 months ]
    as measured by a self-report rating of neuropathic pain symptoms using Neuropathic Pain Symptom Inventory scores

Secondary Outcome Measures :
  1. Number of participants with adverse events [ Time Frame: 12 months ]
    Will collect number of adverse events

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age ≥ 18;
  • Traumatic spinal cord injury;
  • Date of injury occurring within four months of study enrollment.

Exclusion Criteria:

  • More than four months since date of injury;
  • Contraindications for the study intervention, transcutaneous electrical nerve stimulation (TENS),88 including:
  • Implanted electronic device such as a pacemaker;
  • Cardiovascular problems;
  • Pregnancy;
  • Epilepsy;
  • Cancer;
  • Persons with a spinal cord injury at the C2 level, as placement of TENS electrodes on the neck is not recommended;
  • Cognitive dysfunction which limits the ability of the participant to adequately understand procedures and risks.
  • Prisoners
  • Pregnant Women

Special populations:

  • Adults unable to consent: excluded from study
  • Individuals -who are not yet adults: individuals who are less than 18 years old will be excluded from the study
  • Pregnant women: Women who are known to be pregnant will not be recruited into the study. A pregnancy test will be administered to females prior to enrollment in TENS (or sham) treatment. Women who become pregnant before or during the 8-week TENS treatment period will be discontinued from the study. Women who become pregnant after the 8-week TENS treatment portion of the study will continue to be enrolled, and followed according to protocol guidelines (no information will be collected specifically on the pregnancy or fetus).
  • Prisoners: excluded from study
  • Neonates: not applicable
