About this study

Official title: Evaluation of the Effectiveness of the Spa Therapy Program for Rheumatology at Santenay in Patients With Knee Osteoarthritis

The aim of this clinical trial is to assess the efficacy of the 18-day balneotherapy program (therapeutic indication: Rheumatology) in terms of functional incapacity and the disorders (pain, joint stiffness) induced by osteoarthritis of the knee, and thus improves patients\' quality of life, in patients presented with knee osteoarthritis.

The French National Academy of Medicine encourages the re-use of RCT data when available. In this context, the current study is designed as a single-arm prospective study with external comparison using the propensity score. The Control group consists of the patients which were allocated to the Control group of reference randomized clinical trial (RCT) "ANGELLO Study" (NCT05819437). These patients received standard care for knee osteoarthritis, i.e., pain management and exercise recommendations.

All patients enrolled in the current study benefit of 18-day balneotherapy program (therapeutic indication: Rheumatology) with Mineral Water of Santenay (Burgundy, France), and examination with a practitioner at enrollment and 6 months after the beginning of spa treatment.

Read the detailed description

For study purposes, two medical visits with the investigator are organized: the first in the 28 days preceding the 18-day balneotherapy program, or at the latest on the first day of the program, before the first care, and the second 6 months after the start of the program. A remote visit at 3 months is also organized.

The data required for study evaluations are collected by the investigator or self-evaluated by patients during the visits.

Patients of the study receive the same exercise recommendations than the patients of the Control group of the reference study, and their body weight as well as physical ability are monitored.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Balneotherapy program in rheumatology indicationOther

    At least 4 balneotherapy sessions per day, 6 days a week during 3 consecutive weeks that may include: 1 whirlpool bath per day, 1 poultice application per day, 1 bath with immersion showers in a pool per day, a local jet shower every other day, a penetrating shower every other day.

    Alternative treatments may replace penetrating shower or local jet shower, or other care, e.g., collective jet shower or steam bath. 10-minute air diffusion baths are taken in individual tubs at 37°C. Mud is applied 10 minutes as a poultice to both knees (minimum 2 per knee, 52°C), if necessary, to other painful osteoarthritis areas. 10-minute collective pool bathing takes place in a thermal pool equipped with jet stations immersed in water at 32°C. 3-minute local jet shower is applied to the predefined area using thermal water at 37°C. 10-minute penetrating showers are delivered by an affusion ramp on the patient lying down and directed on the area defined, using thermal water at 37°C.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Minimal Clinically Important Improvement (MCII) at 6 months

    MCII is defined as a pain reduction of 19.9 mm or more on a 0-100 visual analogic scale (VAS), where 0 means no pain and 100 worse pain.

    The percentage of patients achieving MCII is calculated and compared with that of the control group in the reference RCT (external comparison).

    Measured: 6 months

  2. Minimal Clinically Important Improvement (MCII) at 6 months

    MCII is defined as a reduction of 9.1 points or more in the function subscale of the Physical function subscale of the Western Ontario and McMaster Universities Arthritis Index (WOMAC) in absence of knee surgery.

  13. Changes from baseline of 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 patient health state. Mean variation is compared with that of the control group in the reference RCT (external comparison).
