Effect of therapeutic exercise on knee osteoarthritis after intra-articular injection of botulinum toxin type A, hyaluronate or saline: A randomized controlled trial
Bibliographic record
Abstract
OBJECTIVE: To study the effect of therapeutic exercise on knee osteoarthritis after injection of botulinum toxin type A, hyaluronate or saline. METHODS: Sixty participants with knee osteoarthritis were randomly assigned to 3 groups: injection of saline (control) (group A), botulinum toxin type A (group B), or hyaluronate (group C). All participants received therapeutic exercise. Western Ontario and McMaster Universities Osteoarthritis Index questionnaire score, visual analogue scale pain scale, and Medical Outcomes Study 36-item Health Survey were conducted at baseline, and at the end of the 4th and 8th weeks. RESULTS: At end of the 4th and 8th weeks, the scores on the Western Ontario and McMaster Universities Osteoarthritis Index questionnaire and visual analogue scale were higher in the control group. There were significant differences in Physical Component Summary-36 and Mental Component Summary-36 scores between the 3 groups (p <0.05) at the end of the 4th and 8th weeks, but not between groups A (control) and C (hyaluronate) at the end of the 4th week. No changes were seen on magnetic resonance imaging and X-ray images of the affected knees after the intervention. CONCLUSION: Therapeutic exercise plus botulinum toxin type A or hyaluronate injection can significantly reduce pain and improve knee functioning. Botulinum toxin type A plus therapeutic exercise appears to be more effective.

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.
