Efficacy of a home-based hip exercise programme for patients with symptomatic cam femoroacetabular impingement: a randomized controlled trial
Bibliographic record
Abstract
Aims: We aimed to determine if a home-based hip exercise programme, designed to use strength and flexibility exercises to modify pelvic positioning, is superior to usual care in reducing pain and improving function and quality of life in patients with symptomatic femoroacetabular impingement (FAI). Methods: This was a single-blind parallel-group randomized controlled trial. Eligible participants were aged ≥ 16 years and diagnosed with symptomatic cam FAI. A sample size of 94 was needed to detect a clinically important difference. Participants were randomly allocated to: 1) an eight-week home-based exercise programme focused on posterior pelvic tilt supervised by a physiotherapist every two weeks in addition to usual care; and 2) usual care. The primary outcome measure was function (patient-reported 33-Item International Hip Outcome Tool (iHOT-33)) and secondary outcome measures were quality of life (EuroQol five-dimension five-level questionnaire (EQ-5D-5L)), and pain (visual analogue scale (VAS)) at baseline, nine weeks, and six months. The Mann-Whitney U test was used to test between-group differences in scores using a two-tailed level of significance of p < 0.05. Results: A total of 95 participants were recruited (48 intervention, 47 control), 55 were males (57.9%), the mean age was 32 years (SD 8.5), and both groups were similar at baseline. There were no statistically significant differences in the primary outcome measure between groups at nine weeks and six months for function (nine weeks: p = 0.394, 95% CI -15.5 to 6.5; six months: p = 0.526, 95% CI -8.8 to 13.7). There were no statistically significant differences in the secondary outcome measures between groups: pain (nine weeks: p = 0.153, 95% CI -0.4 to 2.4; six months: p = 0.743, 95% CI -1.1 to 1.7), and quality of life (quality of life VAS nine weeks: p = 0.877, 95% CI -10.0 to 6.0; six months: p = 0.269, 95% CI -15.0 to 5.0; index value nine weeks: p = 0.815, 95% CI -0.067 to 0.052; six months: p = 0.217, 95% CI -0.099 to 0.020). Conclusion: Our results demonstrated no statistical differences in pain, function, and quality of life for participants following an eight-week home-based exercised programme supervised by a physiotherapist compared to usual care.

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.
