Summary
Brief summary
Aim: To assess, using a parallel-group randomized controlled design, the effect of topical Diprosone OV ointment administered 3 times daily compared to placebo in reducing pain and improving function in participants with hand osteoarthritis over 6 weeks.
Hypothesis: Topical Diprosone OV ointment administered 3 times daily would be more effective than placebo in reducing pain (visual analogue scale) and improving function (assessed using validated questionnaires and grip strength) in participants with hand osteoarthritis over 6 weeks.
