P128 Double-blind randomized pilot study to evaluate diamagnetically enhanced transdermal ibuprofen in comparison to placebo on pain and function in individuals with knee osteoarthritis
Bibliographic record
Abstract
Abstract Background/Aims Treatment of knee osteoarthritis (OA) focuses on reducing pain and improving function. Transdermal NSAID formulations have been developed as an alternative approach to reduce pain and sensitisation around the OA affected joint whilst avoiding some of the risks associated with oral NSAID administration. The aim of the study was to evaluate clinical outcomes following short-term (48 hours) administration of transdermal ibuprofen (5% w/v) from a wearable patch that incorporated a patented diamagnetic repulsion technology to enhance drug delivery, in comparison to placebo. Methods Double-blind, repeated measures, crossover design. Two study periods (48 hr each); diamagnetically enhanced ibuprofen or placebo, randomised. Participants: 24 (6 male: 18 female, mean age 66) people with painful knee OA. Patch applications: 6 x 4-5 hour patch applications over a 48 hour period. Active patches contained 5% ibuprofen in a gel reservoir with magnetized backing. Placebo patches had identical appearance but no ibuprofen and non-magnetized backing. Primary outcome measures: VAS for pain on movement (STS X3), WOMAC pain score, WOMAC function score. Results: Conclusion The active device containing ibuprofen (5%) and magnetophoresis technology produced a significantly greater reduction in pain and improvement in function than the placebo device. This was particularly the case for movement related pain. The reduction in pain was apparent with both VAS pain ratings and WOMAC pain score. There was also a clear improvement in function based on the WOMAC function score. The number needed to treat (NNT) for a 50% reduction in movement related pain was 2.2 and for resting pain 3.4. There were no major adverse events recorded during the study. Disclosure J. Summers: None. T. Wright: None. H. Benson: None. P. Moss: None. G. Tsadilas: None. J. Edwards: None. R. Will: None.

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.
