Using realistic brain-injury models to improve recovery after TBI
Translational Modeling of Brain Injury Rehabilitation to Maximize Recovery.
This project builds a realistic large-animal model of traumatic brain injury to find rehabilitation approaches that help people recover thinking, sleep, and daily function after TBI.

What this research studies
Researchers will use a pig model that reproduces human-like traumatic brain injuries, including diffuse axonal damage and effects on the brain systems that control consciousness, sleep, and fatigue. The team will apply controlled rotational acceleration to animals and measure brain changes, blood markers, behavior, and recovery patterns to better mirror what happens in people. Findings will be used to identify targets and timing for rehabilitation strategies that could be tested in veterans and civilian patients. Work is led at the Philadelphia VA Medical Center in collaboration with the University of Pennsylvania.
Who could benefit from this research
Good fit: People who have had a traumatic brain injury—especially veterans or others with moderate TBI and ongoing problems with cognition, sleep, or fatigue—would be the intended beneficiaries of follow-up clinical work.
Not a fit: People without TBI or those whose problems are unrelated to sleep, fatigue, or cognition are unlikely to receive direct benefit from this animal-focused work.
Why it matters
Potential benefit: If successful, this work could point to better, targeted rehabilitation methods that improve thinking, sleep, and daily functioning after traumatic brain injury.
How similar studies have performed: Large-animal (swine) rotational TBI models have been used by other groups to reproduce human-like injuries, but translating those findings into proven rehabilitation improvements remains early and not yet established.
