About this trial
This is an interventional treatment trial for Chronic Low Back Pain focused on measuring Back Pain
Eligibility Criteria
Inclusion Criteria:
- Chronic Low Back Pain ≥ 6 months duration in the lumbar region, present more than half the days of the month, and on average be at a moderate level of severity in the last month
- At least one trial of physician recommended medication (e.g. acetaminophen, NSAIDS, skeletal muscle relaxants)
- Pre-existing opioid and non-opioid pain medication must be non-existent or stable (medications have not changed for one month)
- Be able to understand, read and write English

- Current DSM-IV diagnosis of substance dependence for alcohol, sedative/hypnotic drugs, stimulants, cocaine
- Current cancer, infection, or inflammatory arthritis
- Broken skin or other lesions in the area of the electrodes
- Uncontrolled medical problems, such as diabetes mellitus, hypertension, pulmonary or airway disease, heart failure, coronary artery disease, or any other condition that poses a risk for the subject during participation

Outcomes
Primary Outcome Measures
West Haven-Yale Multidimensional Pain Inventory (WHY-MPI) General Activity Subscale Rating
The WHY-MPI General Activity subscale contains 18 items summed to give a score ranging from 0 to 108 (higher scores indicate more activity [better]).
Pain Anxiety Symptom Scale (PASS-20) Rating
The PASS-20 contains 20 items and scores could range from 0 to 100 (higher scores indicate greater pain anxiety).

5. Study Description
Brief Summary
The goal of this study is to investigate the role of central neural pathways in mediating chronic pain. The aim of the study is to test the effect of stimulating brain regions that are part of a network underlying central pain processing using a non-invasive brain stimulation technique, transcranial Direct Current Stimulation (tDCS). Prior studies have used tDCS to target both sensory related cortical areas and those important for higher-order representations of pain. This study will target brain regions important for the behavioral response to the chronic sensation of pain. The hypothesis is that stimulation of these brain regions can modulate not only the affective component of pain, but ultimately also improve functioning and quality of life. This hypothesis will be tested by treating study participants eighteen and older with chronic low back pain (CLBP) of greater than six months using tDCS. To be part of this study, participants must meet all the inclusion and exclusion criteria.
