Patients and methods: This prospective, single-blind, randomized-controlled study included a total of 61 patients (8 males, 53 females, mean age 59.22 years; range, 35 to 78 years) who were diagnosed with hand osteoarthritis (HOA) according to the American College of Rheumatology criteria between November 2016 and February 2017. The first group (group 1) (n=31) received paraffin therapy + home-based exercise program and the second group (group 2) (n=30) received home-based exercise program alone. All patients were assessed using the Visual Analog Scale (VAS), Australian/Canadian (AUSCAN) Osteoarthritis Hand Index, Health Assessment Questionnaire (HAQ), Hand Grip Strength (HGS), and Finger Pinch Strength (FPS) at baseline and at two and six weeks after the intervention.

Results: In group 1, there were statistically significant improvements in all parameters at two and six weeks (p<0.05). Statistically significant differences were observed in the HGS and AUSCAN Osteoarthritis Hand Index scores in group 2 at two and six weeks (p<0.05). Inter-group analysis showed statistically significant differences in favor of group 1 in the VAS, HAQ, AUSCAN Osteoarthritis Hand Index, HGS, and FPS scores at two and six weeks compared to baseline scores (p<0.05).

Conclusion: Paraffin therapy combined with home-based exercise program in patients with symptomatic HOA provides effective pain control and is effective in improving functional status, HGS, FPS, and QoL in short term. Keywords : Hand osteoarthritis; home-based exercise; paraffin therapy
