An Assistive Knee-Ankle-Foot-Orthosis and Sit-to-Stand Biomechanics
Bibliographic record
Abstract
Knee-Ankle-Foot-Orthoses (KAFOs) are leg braces designed to assist in standing for patients with limited lower extremity function. The brace holds the knee extended and the ankle in a neutral position, thereby controlling balance and joint alignment. KAFOs have a variety of applications from skeletal complications to muscular weakness and paralysis (1). Patients experiencing such conditions are often dependant on the use of a wheelchair. Standing, therefore, becomes an important physiological function with benefits including pressures relief, spasticity reduction, bowel-and-bladder management, among others (2). However, since a KAFO limits knee and ankle motion, rising from a chair becomes a significant challenge as it requires substantial upper body strength to hoist oneself from seated position. Consequently, many KAFO users are unable to achieve sit-to-stand (STS) independently.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
