Many important rehabilitation outcomes evolve over weeks or even years after injury, yet common outcome assessment methods examine point-in-time events, such as at rehabilitation discharge. Researchers have begun to apply advanced longitudinal methods to facilitate understanding of individual progression of rehabilitation outcomes. This symposium will describe the conceptual model for evaluating outcomes as trajectories of recovery, and present results from three longitudinal stroke rehabilitation studies to demonstrate clinical applications and interpretations of longitudinal mixed effects regression models. Results of each study will be discussed in the context of clinical applications and implications.

Learning Objectives:

• Upon completion, participants will be able to describe the conceptual model for for modeling outcomes as trajectories.
• Discuss the clinical implications of describing the effect of a community-based stroke camp on stress as trajectories of perceived stress.
• Upon completion, participants will be able to discuss the clinical implications of modeling comparative effectiveness as trajectories of change for motor improvement and quality of life outcomes.
• Discuss the clinical implications of describing recovery after stroke as trajectories of mobility and daily activities functioning.
