Abstract

Background: The aim of this study is to test if adjuvant hydrotherapy with viscosupplement is beneficial on management of pain, stiffness, function, and mental relaxation in knee osteoarthritis (OA).
Methods: Nineteen patients with OA were randomly assigned to hydrotherapy or control groups. All patients received viscosupplement injections once a week for 3 weeks. Hydrotherapy group (n=9) had a spa containing green tea, 3 days a week for 2 weeks. The control group (n=10) received only injections. All patients were assessed at baseline and after the third injection. All were assessed for pain (visual analog scale, VAS), pain severity, and functional status (Western Ontario and McMaster Universities osteoarthritis index, WOMAC), emotional status, quality of life (Euro quality of life health-related quality of life inventory five dimension, EQ-5D), and relative spectral power of alpha waves in electroencephalography (EEG).
Results: Both groups reported a statistically significant reduction of pain at the end of treatment and detailed assessment of pain, and function in WOMAC and the relative power of alpha in electroencephalogram showed statistical significant difference only in the hydrotherapy group. However, there were no significant intergroup differences, except for VAS score.
Conclusion: Adjuvant 2-week hydrotherapy to viscosupplement might have a modest role in the management of pain and functional disability and the mental relaxation in patients with knee OA. Larger, randomized controlled trials with intervention of long term period to determine efficacy in treating knee OA are warranted.
