An Overview of Acquired Brain Injury Rehabilitation Randomized Controlled Trials
Bibliographic record
Abstract
OBJECTIVE: To summarize randomized controlled trials published in the acquired brain injury rehabilitation literature. SETTING: N/A. PARTICIPANTS: N/A. DESIGN: Systematic literature review. MAIN MEASURES: A total of 143 published randomized controlled trials in acquired brain injury rehabilitation literature from January 1980 to October 2012. Measures were area of research, number of studies, sample size, methodological quality, and country of origin. RESULTS: There were no significant differences in median sample sizes (P = .212; 95% confidence interval [CI], 0.199-0.215) or PEDro scores (P = .492; 95% CI, .491-.510) between 4 research areas in acquired brain injury: sensory-motor, cognitive-communication, medical complications, and psychosocial. Between 1980 and 2012, there was no significant difference in median sample sizes (P = .202; 95% CI, 0.198-0.214). Median PEDro scores did not significantly improve between 1983-1987 (median = 4, interquartile range = 4.5) and 2008-2012 (median = 6, interquartile range = 2; P = .100; 95% CI, 0.093-0.105). CONCLUSIONS: This study demonstrates the need for more randomized controlled trials, increased sample sizes, and improved methodological quality to better guide clinical practice for acquired brain injury rehabilitation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
