Rationale * Statement of the Problem. Low back pain is a significant societal problem in the United States, affecting approximately one-fourth of all Americans at any given time. Non-pharmacological therapies have not been well studied although preliminary evidence shows the utilization of bracing may be beneficial in reducing pain and medication usage. * Hypotheses or Key Question. The investigators hypothesize that the use of an inelastic lumbar brace may decrease opioid use in chronic low back pain patients on a stable opioid regimen. The investigators propose to conduct a randomized controlled study to test our hypothesis. * Specific Objectives. AIM 1: To evaluate the opioid consumption in chronic low back pain patients on a stable opioid regimen in a three armed trial, after an intervention of an in-elastic lumbar brace, elastic abdominal binder (standard care), and no brace (control). AIM 2: To evaluate changes in secondary endpoints such as pain intensity, quality of life, and functional capacity. Long Term aims: To decrease patient's chronic pain level, improve overall daily function, decrease overall opioid intake and improve quality of life.
Background and Significance Low back pain (LBP) is a common problem in our society with potential for significant morbidity and mortality. One of the treatments for LBP, opioid therapy, has been increasingly utilized for noncancerous pain,1 and has a 4.2% prevalence in the United States alone.2 The long term use of opioids carries its own risk for adverse events and risk of addiction.3 Thus, with the lack of evidence based research for treatments of LBP, the rising epidemiology of LBP in the US, the rise in cost of medical care, along with the potential risks of opioid therapy, our attention needs to be drawn to find more affordable alternatives. Our study proposes to evaluate whether an inelastic lumbar brace will reduce chronic opioid use in the chronic low back pain population. The specific aims of this project are to perform a pilot study to assess the feasibility of this project and plan for a larger randomized controlled trial. Additional long-term goals of this study are to assess the effect of an inelastic lumbar brace in a chronic LBP population, and if there is a significant decrease in opioid use and subsequent control or reduction of pain. Secondary endpoints will note improvement in functional outcomes and other quality of life measures. The findings of this preliminary study conducted at the VA facility will provide data to perform a large multi-center randomized controlled trial and prepare for a NIH proposal to study other benefits of inelastic lumbar bracing.

RECRUITINGBrace fitting and assessment
Visit 1: Screening \& randomization Study parameters and informed consent will be explained and given to potential participants. If interested, study staff will confirm eligibility and randomize the patient into a group. Patient demographics, medical history and surgical history will be obtained as well as basic vitals. A study team member will then perform the physical function exam, administer the pain assessment, and record current opioid use. Patients will then be fitted for a brace (for those with a brace) and instructed to wear the brace all day, every day except when sleeping or showering. Patients will then be given the packet of quality of life questionnaires and ODI surveys and given ample time to fill them out. Before leaving, patients will schedule the next two phone call checkups and the 3 month visit.
Time frame: Initial visit (month 1 of 12)
Pain and opioid reduction
Visit 2 (3 month visit) When the patient arrives for their appointment, they will leave all bracing in the car so that the physician is blinded when recording information. A study team member will take vitals, review any changes in medication or adverse events and then perform a physical exam documenting range of motion, degree of tender points, and hamstring tightness. The study team member will also record the patients brace wearing compliance, pain assessment and perform a pill count for opioid consumption. The patient will then be asked to fill out the ODI and other quality of life surveys (SF-12 and MPI). Prior to leaving the patient will schedule monthly telephone contacts for the next 8 months as well as their last physical visit at the 12 month time point.
Time frame: Visit 2: (month 3 of 12)
Pain and opioid reduction
Visit 3 (12 month visit) When the patient arrives for their appointment, they will leave all bracing in the car so that the physician is blinded when recording information. A study team member will take vitals, review any changes in medication or adverse events and then perform a physical exam documenting range of motion (active and passive), degree of tender points, and hamstring tightness. The study team member will also record the patients brace wearing compliance, pain assessment and perform a pill count for opioid consumption. The patient will then be asked to fill out the ODI and other quality of life surveys (SF-12 and MPI). All patients will be notified that they can keep their brace, if they were given one for the study and that they have completed the study.
Time frame: Visit 3 (month 12 of 12)
