Abstract
OBJECTIVE: To evaluate hip abductor strength-training for patients with unilateral transfemoral amputation. DESIGN: Single-blind, cross-over (AB/BA) trial with randomization. SUBJECTS: Seventeen patients with transfemoral amputation. METHODS: Subjects completed 8-week programs of twice weekly hip abductor strength training or arm ergometry. Subjects were randomly assigned to receive either the experimental or active control intervention first. A physiotherapist blinded to group assignment conducted baseline and post-intervention assessments. The Timed Up & Go (TUG) test was selected as the primary outcome measure; secondary measures included the 2 Minute Walk (2MW), hip abductor strength, Activities Specific Balance Confidence Scale (ABC) and prosthetic use. A two-way cross-over ANOVA was used for baseline and post-intervention treatment comparisons. RESULTS: There were no baseline differences between treatments for TUG, 2MW, ABC, Houghton scale, sitting or side-lying abductor strength (p > 0.05 for all), though supine strength was greater for the experimental treatment (p < 0.05). After 8-weeks of hip abductor strength training, there were significant treatment effects for TUG, ABC (p < 0.01 for both), 2MW (p < 0.05), sitting and side-lying abductor strength (p = 0.05 for both), but not for supine strength, prosthetic use, nor thigh girth measures (p > 0.05 for all). CONCLUSIONS: This study suggests that patients with unilateral transfemoral amputation can improve functional performance and balance confidence following intense hip abductor strength training.

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 it
