Education/Exercise and Chiropractic for Chronic Back Pain

As a needed first step prior to a planned full-scale RCT, in order to assess the feasibility of the RCT and refine its design and protocols, we will perform a pilot study with the following objectives:1.To assess whether enough veterans with chronic LBP can be identified, meet eligibility criteria and be randomized to demonstrate that recruitment for a planned full-scale RCT is feasible. 2.To assess whether veterans with chronic LBP will adhere to protocol interventions per study protocol. 3.To assess whether veterans with chronic LBP will complete data collection per study protocol. 4.To obtain estimates of effect sizes and the corresponding standard errors of the primary efficacy outcome measures to estimate the required sample size of a planned full-scale RCT.
