- Visual Analog Scale (VAS) [ Time Frame: Change from Baseline at 5, 12 and 24 weeks. ]Visual Analog Scales (VAS): The VAS has become very popular in pain research and in the clinical assessment of pain. The test has shown test-retest reliability, intra-examiner reliability and inter-examiner reliability.
- Modified Oswestry Disability Index (mODI) [ Time Frame: Change from Baseline at 5, 12 and 24 weeks. ]The back pain specific, self-rating scale evaluates the degree of functional impairment that a patient is experiencing in a number of activities of daily living. John O'Brien first developed it in 1976. Since that time, the original authors have created a revision, the ODI 2.0. The ODI has been found to have high reliability for test-retest and also for internal consistency. The ODI has been shown to reliably predict functional disability as tested by functional capacity evaluation and physical performance tests. There is no direct cost involved in the administration of this test and there are no adverse effects associated with the administration of this test.
- Patient Reported Outcome Measurement Information System (PROMIS) Physical Function [ Time Frame: Change from Baseline at 5, 12 and 24 weeks. ]As part of the National Institutes of Health Roadmap PROMIS was developed to address several shortcomings of the historically used patient reported outcome questionnaires. PROMIS attempts to acquire precise meaningful data in a short number of questions by the application of item response theory, and CAT 31. This has resulted in an electronic questionnaire of between 6 and 12 questions. PROMIS has varied instruments designed to look at a variety of chronic conditions, for the purposes of this study we will be utilizing the Physical Function instrument, which has been previously utilized in a variety of orthopedic patient populations
- RAND 36-Item Health Survey [ Time Frame: Change from Baseline at 5, 12 and 24 weeks. ]The medical outcomes survey SF-36 was first developed for use in the longitudinal component of a medical outcomes study, a four-year observational study of health outcomes among patients with chronic medical and psychiatric conditions. The RAND 36-Item Health Survey consists of 36 items covering eight generic health concepts: physical functioning, role disability due to physical problems, bodily pain, general health perceptions vitality, social functioning, role disability due to emotional health problems and general mental health. Specific to this study the statistical analysis is based on bodily pain and physical functioning. These two measures have been previously utilized in other research on spinal pain syndromes and found to be reliable and valid.

Specific Aim 1: Utilizing a gold standard sham controlled randomized trial design, we will evaluate the change in pain, back related disability and quality of life in Veterans with CLBP who utilize either a custom foot orthotic or a sham orthotic.
As part of this aim the investigators will build on the teams strength of recruiting and enrolling Veteran's with CLBP into a randomized trial. The investigators will collect baseline pain and disability measures utilizing validated tools. Once the patients are enrolled, utilizing the "gold standard" placebo controlled design the investigators will randomize patients to receive either a custom foot orthotic or a sham orthotic. The Veterans will then be assessed at 5, 12 and 24-weeks post baseline to evaluate differences in pain and disability. Based on previous studies on the effectiveness of custom foot orthotics the investigators hypothesize that that Veteran's who receive the custom orthotic will experience less pain and disability as compared to those who receive the sham orthotics.
Specific Aim 2: To evaluate baseline characteristics of Veterans with CLBP predictive of responsiveness to custom foot orthotics including age, BMI, psychosocial characteristics and arch classification.
Focusing on the Veterans who receive the custom foot orthotic, the investigators next examine the important characteristics that may predict those Veterans who are most likely to benefit from wearing custom foot orthotics. Assessing potential confounders or facilitators of effectiveness of the custom foot orthotic will allow the investigators to best describe potential mechanisms of responsiveness. The investigators have chosen previously described confounders to responsiveness to treatment of CLBP, specifically age, body mass index and psychosocial characteristics. This methodology is particularly important in a sham controlled trial to assess if effectiveness or lack of thereof, is a factor of the intervention or from other confounding variables. The investigators have also chosen to evaluate the arch classification based on the measurement of the Veterans arch; again this allows for specific recommendations concerning use of this product. Based on previous studies on the effectiveness of custom foot orthotics in addition to previous studies evaluating CLBP the investigators hypothesize that those Veterans who are older, have a higher BMI and greater fear avoidance belief scores will show less responsiveness to the custom foot orthotics as compared to those younger Veterans who have a lower BMI and lower fear avoidance belief scores. In addition based on previous biomechanical literature, the investigators feel that those Veterans with a lower arch will show the greatest responsiveness to the custom foot orthotic.
