A total of 200 patients with symptomatic knee OA will be randomly allocated to the SSBD treatment or placebo intervention group for 4 weeks. The two groups of patients are allowed to steam and bathe their knees once every other day, using one packet of SSBD each time, for 30 minutes, 3 times a week, for a total of 4 weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale at 4 weeks is the primary outcome measure, and the secondary outcomes include WOMAC stiffness and function scores, the Lysholm knee scale score, quality of life, the Brief Pain Inventory score, the Patient’s Global Impressions of Improvement Scale score and the Clinical Global Impressions of Severity scale score. The safety of the herbal medications will also be evaluated.Conclusion: We will discuss whether SSBD has greater advantages in terms of efficacy, safety, and patient overall perception than does placebo control in middle-aged and elderly patients with knee OA. The findings may provide new and valuable information about the efficacy and safety of Chinese herbal bath therapy in the treatment of knee osteoarthritis.Keywords: balneotherapy, traditional Chinese medicine, complementary and integrative medicine, randomized placebo-controlled trial, knee osteoarthritis |
