Extended Exercise Rehabilitation After Hip Fracture Improves Patients' Physical Function: A Systematic Review and Meta-Analysis
Bibliographic record
Abstract
BACKGROUND: Although the principal goal of hip fracture management is a return to the pre-event functional level, most survivors fail to regain their former levels of autonomy. One of the most effective strategies to mitigate the fracture's consequences is therapeutic exercise. PURPOSE: The purpose of this study was to review and quantify the reported effects of an extended exercise rehabilitation program offered beyond the regular rehabilitation period on improving physical functioning for patients with hip fractures. SOURCES: The Cochrane libraries, PubMed, CINAHL, PEDro, and EMBASE were searched to April 2012. STUDY SELECTION: All randomized controlled trials comparing extended exercise programs with usual care for community-dwelling people after hip fracture were included in the review. DATA EXTRACTION AND SYNTHESIS: Two reviewers conducted each step independently. The data from the included studies were summarized, and pooled estimates were calculated for 11 functional outcomes. RESULTS: Thirteen trials were included in the review and 11 in the meta-analysis. The extended exercise program showed modest effect sizes (ESs), which reached significance, under random theory, for knee extension strength for the affected and nonaffected sides (ES=0.47, 95% confidence interval [CI]=0.27-0.66, and ES=0.45, 95% CI=0.16-0.74, respectively), balance (ES=0.32, 95% CI=0.15-0.49), physical performance-based tests (ES=0.53, 95% CI=0.27-0.78), Timed "Up & Go" Test (ES=0.83, 95% CI=0.28-1.4), and fast gait speed (ES=0.42, 95% CI=0.11-0.73). Effects on normal gait speed, Six-Minute Walk Test, activities of daily living and instrumental activities of daily living, and physical function subscale of the 36-Item Short-Form Health Survey (SF-36-PF) did not reach significance. Community-based programs had larger ESs compared with home-based programs. CONCLUSIONS: To the authors' knowledge, this is the first meta-analysis to provide evidence that an extended exercise rehabilitation program for patients with hip fractures has a significant impact on various functional abilities. The focus of future research should go beyond just effectiveness and study the cost-effectiveness of extended programs.

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.
