Balneotherapy in the Treatment of Knee Osteoarthritis: A Controlled Study

摘要

Objectives: This study aims to evaluate the efficacy of combined balneotherapy and physical therapy compared to physical therapy alone in thetreatment of patients with knee osteoarthritis.Patients and methods: Forty-six patients (10 males, 36 females; mean age 70.82±7.78 years; range 57 to 85 years) with knee osteoarthritis wereincluded in this study. Patients were assigned as group 1 and 2. Patients in group 1 (n=27) were treated with physical therapy alone, while patients ingroup 2 (n=19) were treated with balneotherapy combined to the same physical therapy protocol. All patients had physical therapy consisting of hotpack, transcutaneous electrical nerve stimulation, and ultrasonography for knee region, 45 minutes per day, five days a week for a total duration ofthree weeks. On the other hand, patients in group 2 also had daily balneotherapy sessions lasting 20 minutes, five days a week, again for three weeksduration. The demographic data and clinical features of the patients were recorded. Sickness impact profile was used for the evaluation of diseaseseverity. Evaluation parameters also included visual analog scale, Western Ontario and McMaster Universities Arthritis Index, 10-meter walking test,and the use of analgesic drugs. Tests were performed both at baseline before treatment and at the end of the third week after treatment.Results: There were no significant differences between the two groups in terms of socio-demographic features. In both groups, significantimprovements were observed for all of the measured variables (all p values <0.01). Moreover, group 2 had significantly superior improvements in allof the parameters compared to group 1 (all p values <0.05).Conclusion: Combined balneotherapy and physical therapy seems to be more effective in advanced knee osteoarthritis for improving pain, physicalfunction and walking speed, compared to physical therapy alone.
