Background: Osteoarthritis (OA), described as Waja‘al-Mafāṣil in Unani medicine, results from an imbalance between degeneration and regeneration of articular cartilage and bone, where natural repair mechanisms become inadequate. It is a major public health issue and a leading cause of disability in developing countries. Wet cupping, an important Unani therapeutic modality, is explored here for its scientific basis through piezo-channels-mechanosensitive ion channels that convert mechanical pressure stimuli, a key component of wet cupping, into electrochemical signals that may influence joint pathology.
Methods: A non-inferiority RCT was conducted on 60 OA patients aged 40-70 years, randomized 1:1 into test (wet cupping) and control (Aceclofenac 100 mg twice daily) groups. The test group received five cupping sessions on days 0, 15, 30, 45 and 60, and both interventions lasted 8 weeks. Outcomes were assessed using WOMAC, 100-mm VAS, and active range of motion, along with subjective symptoms. Safety was evaluated through hemogram, LFT, KFT, and urine tests at baseline and week 8.
Results: Pre-protocol analysis included 60 patients (30 test, 30 control) who completed the study. Both groups showed significant improvement in objective parameters (VAS, WOMAC, AOR) and subjective measures. However, intergroup comparison revealed no statistically significant difference between the test and control groups.
Conclusions: Wet cupping’s mechanotransduction effects explain intergroup differences, suggesting it can serve as an effective alternative treatment for knee osteoarthritis.
