A scoping literature review of studies assessing effectiveness and cost-effectiveness of prosthetic and orthotic interventions
Bibliographic record
Abstract
Purpose: Approximately 1.5% of the world’s population (∼100 million people) need a prosthesis/orthosis. The objective of the study was to establish an overview of the literature that has examined prosthetic and orthotic interventions with a view to inform policy development.Methods: Fourteen databases were searched from 1995–2015. Studies reporting primary research on the effectiveness or cost-effectiveness of prosthetic and orthotic interventions were examined. Metadata and information on study characteristics were extracted from the included studies.Results: The searches resulted in a total of 28,958 articles, a focus on studies with the words “randomized” OR “randomized” OR “cost” OR “economic” in their citation reduced this total to 2644. Research has predominantly been conducted in Australia, Canada, Germany, Netherlands, UK and USA. A total of 346 randomized controlled trials were identified, with only four randomized controlled trials examining prosthetic interventions. The majority of research examined lower limb orthoses in the adult population and used a wide range of outcome measures.Conclusions: While various international organizations have highlighted the value of providing prosthetic and orthotic services, both to the user and society as a whole, the availability of scientific research to inform policy is limited. Future structured evaluation of prosthetic and orthotic interventions/services is warranted to inform future policy developments.Implications for rehabilitationResearch into prosthetic and orthotic interventions has grown substantially in the last 20 years, with most of this research conducted in a small number of countries and focusing on the use of lower limb orthotics in adult populations.Research to date has utilized an extensive range of outcome measures, the development of agreed standardized sets of outcomes would allow comparison and combination of results in future research.This study highlights the need for further research in this area, especially studies which examine the cost-effectiveness of prosthetic and orthotic provision.

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.
