Five-year Pain Intensity and Treatment Trajectories of Post-9/11 Veterans With Mild Traumatic Brain Injury.

ABSTRACT: Pain is a pervasive problem that affects nearly half of the U.S. Veterans deployed in support of the Global War on Terror (Post-9/11 Veterans) and over half of the Post-9/11 Veterans with diagnosed traumatic brain injury (TBI). The goal of the current study was to identify pain phenotypes based on distinct longitudinal patterns of pain scores in light of pain treatment among Post-9/11 Veterans over 5 years of care using latent growth mixture analysis stratified by TBI status. Five pain phenotypes emerged: 1) simple low impact stable pain, 2) complex low impact stable pain, 3) complex low impact worsening pain, 4) complex moderate impact worsening pain, and 5) complex high impact stable pain. Baseline pain scores and slopes were significantly higher in Veterans with mild TBI for some phenot
