Classification schema of posttraumatic amnesia duration-based injury severity relative to 1-year outcome: analysis of individuals with moderate and severe traumatic brain injury.

Objective: Early investigations classified traumatic brain injury (TBI) severity according to posttraumatic amnesia (PTA) duration, designating "greater than 7 days" as the most severe. PTA durations of more than 7 days are common in neurorehabilitation populations. Moreover, no study has derived a PTA severity schema anchored to late outcome.

Evaluation of an interdisciplinary team intervention to improve therapeutic alliance in post-acute brain injury rehabilitation.

Objective: Evaluate an intervention to improve an alliance between an interdisciplinary team and clients with traumatic brain injury attending post-acute brain injury rehabilitation.

Design: Prospective design, 2 consecutive samples-historical control (CNT) and treatment (TX).

Methods: Sample of 104 clients (69 CNT, 35 TX) admitted to post-acute brain injury rehabilitation completed admit/discharge questionnaires.

Evaluation of changes in motor and visual functional activation over time following moderate-to-severe brain injury.

Primary Objective: Relatively little research has documented functional recovery following traumatic brain injury using neuroimaging techniques. This study aimed to examine the effects of moderate-to-severe brain injury on brain functioning over time.

Research Design: Eight brain-injured participants completed motor and visual tasks during fMRI at two time points within the first year following injury.

Variability in Stroop task performance and functional activation among a small brain-injured group.

This study evaluated the effects of moderate to severe brain injury on cognitive task performance and cortical activation. Five participants completed a Stroop task while undergoing functional magnetic resonance imaging (fMRI) at two time points post- injury. Results revealed activation within regions typically activated during a Stroop task (the region of interest: ROI), though variability among participants was evident.

Age-related decrements in performance on a brief continuous performance test.

Research has revealed age-related decrements in performance on a variety of attention-related tasks, including sustained attention, selective attention, and inhibition tasks (e.g., [Armstrong, C.
