Following extremity injury, referral (and direct access) to physical therapy (PT) is considered standard of care. And, while PT strategies are commonly impairment focused, clinicians across multiple subspecialties of physical therapy recognize the importance of addressing pain and pain-related psychosocial factors as strong predictors of chronic pain as well as long-term physical and psychological disability.~Cognitive-behavioral therapy (CBT) interventions have documented positive influence on psychosocial factors in patients with chronic pain. CBT-based self-management programs have also demonstrated improvement in patient outcomes and the adoption of a physically active lifestyle, as well as improvement in fear-avoidance beliefs and self-efficacy, in various populations with chronic conditions. These evidence-based CBT and self-management strategies provide the basis for the study intervention.~The proposed project will conduct a multi-center, randomized controlled trial to determine the efficacy of the CBPT program in patients at-risk for poor outcomes following traumatic lower-extremity injury. Central hypothesis is that delivery of CBPT by physical therapists over the telephone will improve outcomes, through reductions in pain catastrophizing and fear of movement and improvement in pain self-efficacy. The investigators propose a large, rigorous evaluation of the CBPT program in patients with lower extremity trauma with the goal of engaging civilians and service members in their own care and improving pain and functional outcomes.~Specific Aim 1 To determine the efficacy of the CBPT program for improving outcomes in service members and civilians at-risk for poor outcomes following traumatic lower-extremity injury. Primary outcome is physical function measured through a patient-reported questionnaire. Secondary outcomes include physical performance tests, pain and general health. Tertiary outcome is return to work/duty.~Specific Aim 2 To determine whether changes in the intermediary outcomes of pain catastrophizing, fear of movement, and self-efficacy at 6 months are associated with improvement in outcomes 12 months after hospital discharge.~Specific Aim 3 To determine whether subgroups of patients are more likely to benefit from the CBPT program.~Specific Aim 4 To examine the value of CBPT relative to Education using Markov decision-analysis.
The goal of the CBPT study is to determine the efficacy of the CBPT program for improving outcomes in service members and civilians at-risk for poor outcomes following traumatic lower-extremity injury. Primary outcome is physical function measured through a patient-reported questionnaire and physical performance tests. Secondary outcomes include pain and general health. Tertiary outcome is return to work/duty.
