Neuromuscular exercise in addition to celecoxib versus celecoxib alone for symptomatic and radiographic knee osteoarthritis: a randomized controlled trial
Bibliographic record
Abstract
BACKGROUND: Neuromuscular exercise (NEXA) and celecoxib each are effective for treating knee osteoarthritis (OA), but the potential benefits of combination therapy remain unclear. The aim of this study was to investigate the effects of NEXA in addition to celecoxib compared to celecoxib alone on pain and physical function in patients with symptomatic and radiographic knee OA. METHODS: A prospective, assessor-blinded, two-arm, superiority randomised controlled trial. Sixty participants with Kellgren and Lawrence (KL) grade 2-3 symptomatic knee OA were included and randomly assigned 1:1 to undergo 12 weeks NEXA and celecoxib or to receive celecoxib 200 mg once daily alone. The primary outcomes were visual analog scale (VAS) and total Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score at 6 months. The secondary outcomes included the Knee injury and Osteoarthritis Outcome Score (KOOS), six-minute walk test, and Timed Up and Go (TUG) test at 3 months and 6 months. RESULTS: At 6 months, the between-group differences in the VAS score (mean difference, -10.30; 95% CI, -19.38 to -1.23; P = 0.026) and total WOMAC score (mean difference, -10.40; 95% CI, -15.54 to -5.27; P < 0.001) were statistically in favour of the NEXA and celecoxib group. There was evidence that NEXA in addition to celecoxib were superior to celecoxib alone for KOOS symptoms score (P = 0.040), KOOS activities of daily living score (P < 0.001), KOOS sport and recreation score (P = 0.014), KOOS quality of life score (P = 0.036), six-min walk test (P = 0.006), and TUG test (P = 0.001) at 6 months. The NEXA and celecoxib group achieved significantly higher proportions of patients above the minimal clinically important difference in total WOMAC score (78.6% vs. 51.9% for absolute improvement; 75% vs. 37% for relative improvement) at 6 months. CONCLUSIONS: Compared with celecoxib alone, there was a beneficial effect of NEXA in addition to celecoxib on pain and physical function in patients with symptomatic and radiographic knee OA at 6 months.

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.
