Although peloid and paraffin treatments may have a positive effect in the short term on pain, functional status, hand grip strength, and quality of life in patients with hand osteoarthritis (HOA), there are no comprehensive and comparative studies of these therapies for HOA. The aim of our study was to evaluate the short-term effects of peloid and paraffin treatments in symptomatic HOA patients. Eighty female patients diagnosed with HOA were randomly divided into two equal groups: peloid group (peloid therapy and home exercise) and paraffin group (paraffin therapy and home exercise). Peloid and paraffin applications were performed over 3 weeks for a total of 15 sessions. Patients were evaluated with visual analog scale (VAS)-rest, -activity, and -handgrip for pain, Jamar hand dynamometer for grip strength, Australian/Canadian (AUSCAN) Osteoarthritis Hand Index for function, health assessment questionnaire (HAQ) for physical activity, Beck depression inventory (BDI) for depression, and short form-36 (SF-36) for quality of life. Evaluations were performed before treatment, in the 3rd week, and 1 month after treatment. For all parameters except SF-36, statistically significant improvements were observed in short-term evaluations compared to the baseline in both groups (p = .000). Reductions in HAQ scores in the 3rd week and 1st month (p = .001 and p = .003), and the decrease in BDI scores in the 3rd week (p = .005) was statistically significantly higher in the peloid group. Improvements in some subparameters of the SF-36 were statistically significant in favor of the peloid group. In female patients with HOA, both groups experienced similar positive effects on pain, functional status, and hand grip strength for up to one month, but the peloid group was found to be superior in the short term in terms of physical activity and some quality of life parameters. Peloid therapy can be preferred as a natural and reliable method for symptomatic HOA.
