Clinical Trial Summary

The goal of this clinical trial is to assess the efficacy of a 18-day balneotherapy program in the rheumatology indication in patients presented with knee osteoarthritis. The main questions of the study aims to answer are how balneotherapy improves functional incapacity and the disorders (pain, joint stiffness) induced by osteoarthritis of the knee, and thus improves patients' quality of life.

Participants are randomly assigned in control or treatment (spa) groups. All receive standard of care for knee osteoarthritis throughout the study. Balneotherapy program consists of 18-days of spa treatment with Mineral Water of Saint Jean d'Angely. Functional incapacity, disorders and quality of life induced were measured at baseline and then 6 months later.

Variation from baseline were compared in control and treatment groups to assess the efficacy of the balneotherapy program.

Intervention

Other:
• Balneotherapy program
Whirlpool bath, bath with immersion showers, poultice application and underwater massage. The baths were performed in an individual tub in ten-minute sessions. The temperature was set specifically for each patient, on average from 34 to 38°C. These were baths with jets and air diffusion. The mud was applied as a poultice to the 2 knees and if necessary (duration of application: 10 minutes). The massages were carried out by qualified physiotherapists under an affusion ramp of thermal water at 38°C for 10 minutes. The water used is a mixed sulphated Natural Mineral Water, collected by drilling the "capuchins" at a depth of 975 m. The temperature of the water at the outlet of the borehole is 41.8°C and is lowered to 35°C.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Variation from baseline in physical function subscale of the WOMAC at 6 months	Physical function subscale of the Western Ontario and McMaster Universities Arthritis Index (WOMAC) is a self-administered questionnaire that consists in 17 items: (17 items): using stairs, rising from sitting, standing, bending, walking, getting in / out of a car, shopping, putting on / taking off socks, rising from bed, lying in bed, getting in / out of bath, sitting, getting on / off toilet, heavy domestic duties, light domestic duties. The 100-normalized subscale score ranges from 0 (none) to 100 (worse functional limitations).	Baseline (D1) and final (6 months)

The 100-normalized subscale score ranges from 0 (none) to 100 (worse functional limitations).	Baseline (D1) and final (3 months)
Secondary	Variation from baseline in pain subscale of the WOMAC at 3 months	Pain subscale of the WOMAC is a self-administered questionnaire that consists in 5 items: during walking, using stairs, in bed, sitting or lying, and standing upright. The 100-normalized subscale score ranges from 0 (none) to 100 (worse pain limitations).	Baseline (D1) and final (3 months)

Secondary	Changes in participants quality of life at 3 months	Quality of life is measured using EUROQOL (EQ-5D-3L) questionnaire.The EQ-5D-3L descriptive system comprises the following five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results into a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.	3 months
