Brief 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.

Primary Outcome Measures
NameTimeMethod
Variation from baseline in physical function subscale of the WOMAC at 6 monthsBaseline (D1) and final (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).

Secondary Outcome Measures
NameTimeMethod
Variation from baseline in pain-induced knee osteoarthritis intensity at 6 monthsBaseline (D1) and final (6 months)

Pain intensity is measured using a 0 (no pain)-100 (Worse pain) Visual Analogic Scale (VAS).

Variation from baseline in pain subscale of the WOMAC at 3 monthsBaseline (D1) and final (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).

Variation from baseline in pain subscale of the WOMAC at 6 monthsBaseline (D1) and final (6 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).

Variation from baseline in WOMAC total score at 3 monthsBaseline (D1) and final (3 months)

The scores for each subscale are summed up to calculate the total WOMAC score. The 100-normalized score ranges from 0 (none) to 100 (worse limitations).

Variation from baseline in pain-induced knee osteoarthritis intensity at 3 monthsBaseline (D1) and final (3 months)

Pain intensity is measured using a 0 (no pain)-100 (Worse pain) Visual Analogic Scale (VAS).

Number of participants achieving minimal clinically important improvement (MCII) at 6 months6 months

MCII is defined as 19.9 mm or greater on the VAS pain scale and/or 9.1 points or greater on the WOMAC physical function subscale normalized to a 0-100 score, and no knee surgery

Number of participants achieving minimal clinically important improvement (MCII) at 3 months3 months

MCII is defined as 19.9 mm or greater on the VAS pain scale and/or 9.1 points or greater on the WOMAC physical function subscale normalized to a 0-100 score, and no knee surgery

Variation from baseline in stiffness subscale of the WOMAC at 6 monthsBaseline (D1) and final (6 months)

Stiffness subscale of the WOMAC is a self-administered questionnaire that consists in 2 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 stiffness limitations).

Number of participants presented with acceptable symptom state (ASS) at 3 months3 months

ASS is defined as VAS pain 32 mm or less or WOMAC function subscale normalized to a 0-100 score of 31 points or less.

Changes in participants quality of life at 6 months6 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.

Frequency of adverse events throughout the studyFrom inclusion to the final visit at 6 months

Adverse events are described using MedDRA and each event frequency is calculated.
