Study Summary

The primary purpose of the R21 is using an experimental medicine research approach to study whether a chronic, progressive-based exercise program will help Veterans suffering from chronic low back pain (cLBP) and PTSD achieve exercise maintenance, and shared symptom reduction, through neuropeptide Y mediated improvements in putative factors (self-regulation and reward sensitivity) known to improve exercise related self-efficacy and motivation.

Primary Outcome

This 4-item continuous measure categorizes stages of behavioral change based on the Transtheoretical Model (TTM) stages (precontemplation, contemplation, preparation, action and maintenance), specifically in the context of exercise behavior change.

Interventions
