To determine if there is any carry over difference between the type of education provided about common treatment techniques for patients with low back pain. This will be looked at right after treatment and when patients return on their second visit after they do a common exercise program for a few days.

Prior clinical trials have shown that patients respond differently to different explanations about interventions performed. A recent randomized clinical trial demonstrated that a 10-minute manual therapy treatment (prone lumbar Posterior to Anterior mobilization (PA's) with a neuroplasticity vs. traditional biomechanical explanation) produced an immediate, significant improvement in straight leg raise (SLR) and pain for patients with chronic low back pain. However, there is a need to examine whether there is any carry over (48-96 hours) or if utilizing a home exercise program (HEP), aimed at increasing the various sensory process applied in the clinic, produces any carry over. This will be looked at in patients with who are provided different explanations about common back treatment techniques to see if there will be any change in pain rating or back and leg movement.
