Predictors of Continued Prosthetic Wear in Children With Upper Extremity Prostheses
Bibliographic record
Abstract
In Brief The purpose of this study was to determine whether age at initial fit, type of prosthesis, geographic location, gender, or side of limb deficiency were associated with duration of upper extremity prosthetic wear in children. A retrospective chart review of 298 children was conducted at five Shriners Hospitals for Children to determine which factors contributed to longer duration of prosthetic wear in children who were fit with transradial prostheses between 1988 and 1998. Data analysis was performed to answer the following questions: (1) Does age at initial fit or initial type of prosthesis affect prosthetic outcome (defined as more than 3 years of wear)? (2) Does current or final type of prosthesis affect prosthetic outcome? (3) Does geographic location or distance traveled to the clinic affect prosthetic outcome? (4) Does side of limb deficiency or gender affect prosthetic outcome? Children fit with a transradial prosthesis at younger ages wore a prosthesis longer than did children fit at older ages. For current or final type of prosthesis, children who wore a body-powered or myoelectric prothesis were more than two times as likely to wear it > 3 years than were children who wore a passive prosthesis. Finally, children living in Mexico were more than three times as likely to wear a prosthesis > 3 years than were children living in other countries. Initial type of prosthesis, distance traveled to the clinic, gender, or side of limb deficiency were not correlated with duration of prosthetic wear. Age at initial fit, current or final type of prosthesis, and geographic location were predictors that correlated with longer duration of prosthetic wear in children wearing transradial prostheses. The purpose of this retrospective chart review of 298 children was to determine whether age at initial fit, type of prosthesis, geographic location, gender, or side of limb deficiency were associated with duration of upper extremity prosthetic wear in children. The authors found that children fit with a transradial prosthesis at younger ages wore a prosthesis longer than did children fit at older ages, that children who wore a body-powered or myoelectric prothesis were more than two times as likely to wear it > 3 years than were children who wore a passive prosthesis, and that children living in Mexico were more than four times as likely to wear a prosthesis > 3 years than were children living in other countries.

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.
