Design and Evaluation of a Prosthetic Knee Joint based on Automatic Stance-Phase Lock (ASPL) Technology for Children with Transfemoral Amputations
Bibliographic record
Abstract
The objectives of this study were to adopt the automatic stance-phase lock (ASPL) technology to a paediatric prosthetic knee, optimize and incorporate the extension assist to the proposed design, structurally and clinically validate the prototype of the knee in a structural testing and single subject pilot study, and use a questionnaire to evaluate its efficacy. Biomechanical models were used to analyze the gait characteristics of the participant with the proposed knee and the conventional knee joint used by the participant in the clinical pilot study. A questionnaire pertaining to the functions and characteristics of the proposed knee joint was administered to the participant. The results of the clinical study indicated that the stance phase performance of the proposed design is comparable to the conventional knee. Questionnaire results revealed participant was very confident with the design, and was able to participate in many activities such as running and playing dodge ball.

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.
