This document contains summaries of several poster presentations from an annual medical conference. It includes 3 posters on topics related to brain injury and rehabilitation:
1. A study examining factors that contribute to fatigue after traumatic brain injury, finding that depression, memory problems, pain, and abnormal hormone levels were significant predictors of fatigue.
2. A study validating a new pain assessment scale called the Scale of Pain Intensity for patients with cognitive and communication deficits after brain injury. It was found to accurately identify pain and track changes.
3. A study finding an increasing incidence of traumatic brain injury in the elderly using national hospitalization data, suggesting this may be an area for further research.
