Roland-Morris Disability Questionnaire (RMDQ)
The RMDQ is a subjective measure of disability recommended for LBP. Users are asked to identify among 24 activities or statements that are influenced by their back pain. The answers provide a score between 0 and 24, with higher scores representing more disability.

Numeric Pain Rating Scale (NPRS)
The NPRS is an 11-point scale used to rate subjective pain intensity. The NPRS has been shown to have good validity and reliability. The scale ranges from 0 to 10 and has been shown to have acceptable responsiveness in patients with LBP. This study's scale was anchored at 0, "no pain at all", to 10, "the worst pain you could imagine."

Brief Survey of Pain Attitudes (SOPA-35)
The Brief Survey of Pain Attitudes (SOPA-35) is a valid, reliable, and sensitive questionnaire that measures beliefs about pain across 7 domains. This study was particularly interested in the harm sub-scale to assess whether patient's beliefs that pain means harm changes after the intervention. Each domain is scored from 0-4 with 0 representing "very untrue" and 4 representing "very true." A higher score for the SOPA-Harm subscale indicates that participants believe that pain is a sign of harm and damage to a greater degree than participants with a lower score on the scale.

Lumbar Spine Pain Pressure Threshold (PPT)
Patients were tested in the prone position with a pillow under their shins to achieve approximately 15 degrees of knee flexion. A research physical therapist applies a digital algometer probe (SBMEDIC Electronics, Sweden) with a gradual increase in force 5 cm lateral to the spinous process of L3 of the most symptomatic side until the participant reported the pressure as painful and pressed a button attached to the algometer. This procedure was performed three times at the low back and averaged to determine the patient's Pain Pressure Threshold with approximately 30 seconds rest between repetitions. Forces are measured in kPA with higher numbers indicating a greater tolerance for pressure and potentially less pain sensitivity.

Spinal flexion
Participants were asked to bend forward at the waist while keeping their knees straight and attempting to touch the floor. The distance from the floor to the patient's most distal finger-tip was measured to the nearest tenth of a centimeter (cm). Participants were instructed to stop "whenever you feel you need to stop." Participants completed this procedure two times and the measures were averaged. Lower numbers indicate greater range of motion with the lowest score possible 0cm.

Healthcare utilization, Cost
Any medical appointment in the Veterans Affairs or Department of Defense health system in which a patient sought care or was evaluated for complaints of LBP for 12-months following study enrollment according to a medical provider's electronic documentation of the visit. Subsequently, a physical therapist who was blinded to participant group allocation verified each medical encounter and then extracted all current procedural terminology (CPT) codes that were charged for each visit related to LBP. In the Military and Veterans Health Affairs, costs are estimated based on the American Medical Association and Medicare equivalents for CPT codes.

5. Study Description
Brief Summary
This trial compared traditional pain and stress education plus physical therapy to pain neuroscience education plus physical therapy in individuals with post-traumatic stress and chronic low back pain.
Detailed Description
Veterans and Service Members with low back pain (LBP) will be recruited for this research. Once Veterans consent to participate in this research, participants will undergo baseline testing. Next, participants will randomly be assigned to one of two types of education: pain neuroscience education or traditional biomedical education. Each Veteran will receive 30 minutes of interactive education once a week for 4 weeks, depending on their group assignment. Following each education session, Veterans will participate in an exercise class that will last approximately 30 minutes. After the 4 week intervention, Veterans will complete the same questionnaires and measures as at the beginning of the program. Veterans will also complete subjective questionnaires at 8 weeks. Finally, healthcare utilization will be measured for 12 months following the research intervention.

Intervention Name(s)
Pain Neuroscience Education
Intervention Description
Weekly education sessions lasting approximately 30 minutes each, once a week for four weeks.
Session 1: the nervous system is like an alarm to protect.
Session 2: common ways the nervous system becomes sensitive.
Session 3: importance of gradual conditioning and neuroplasticity.
Session 4: common ways to decrease nervous system sensitivity.

Intervention Name(s)
Exercise
Intervention Description
The exercise protocol for each group will be identical and modeled after the "Back to Fitness" program. This program will consist of a 5-10-minute cardiovascular warm-up of walking in place or riding an exercise bike. Next is a 15-minute circuit consisting of 10 different general exercises for 1-minute each. Finally, a 5-minute cool down will consist of light stretching and trunk range of motion exercises. Each exercise will be tailored as easy, medium, or hard depending on the individual patient's tolerance. This program has been shown to be equally as effective as motor control exercises for long-term outcomes in patients with non-specific LBP.
