LARYTHERM: Benefits of Spa Therapy in Saint-Lary Soulan for Knee Osteoarthritis
Study Details
Study Description
Brief Summary
The hypothesis is that the use of spa therapy in Saint-Lary Soulan for knee osteoarthritis treatment would have a therapeutic effect on this pathology.
The main objective of this external comparison study is to evaluate the comparative effectiveness at 6 months of spa therapy in the Saint-Lary Soulan spa center on functional disability and pain (MCII: Minimal Clinical Important Improvement) in knee osteoarthritis compared to the control group of the Thermarthrose multicenter randomized clinical trial, receiving standard cares.
The patients included in the Larytherm cohort will undergo a three-week spa therapy in Saint-Lary Soulan with a follow-up of 6 months after the end of spa therapy.

Detailed Description
Knee osteoarthritis is a frequent disease with important consequences for quality of life of patients. In France, prevalence was estimated at 7.6% among subjects between 40-75 years old. The management of knee osteoarthritis is essentially based on lifestyle and dietary measures and the use of analgesic treatment. Spa treatments are also part of the overall management of this pathology.
In this context, the spa town Saint-Lary Soulan requests the approval of the " Rheumatology " therapeutic orientation for its new borehole water (SL5), which requires a study (Larytherm) conducted according to the criteria of the French Academy of Medicine.
Secondary objectives are to evaluate 6 months after spa therapy in Saint-Lary Soulan, the evolution of:
-
Body Mass Index (BMI),
-
knee pain due to knee osteoarthritis,
-
functional impact,
-
fatigue,
-
physical activity,
-
quality of life,
-
consumption of analgesic treatments,
-
the occurrence of episodes of joint effusion requiring puncture/infiltration,
-
the occurrence of adverse events.
The patients will be identified by local physicians or through a local public communication campaign. The patients with criteria of eligibility will complete a self-reported questionnaire before the beginning of spa therapy, after the spa therapy and 6 months after the end of spa therapy, and the physicians practising at the spa center will complete a medical questionnaire at inclusion and after the spa therapy.

Outcome Measures
Primary Outcome Measures
- Number of patients with Minimal Clinically Important Improvement (MCII) [6 months after the end of spa therapy]
Improvement from baseline of at least 9.1 points on the Western Ontario and McMaster University osteoarthritis (WOMAC) index standardized functional subscale of 0-100 and/or at least 1.99 cm on the Visual Analogue Scale (VAS) for pain without knee surgery, at 6 months. WOMAC index (functional subscale): functional assessment index for knee osteoarthritis, exploring the daily function. The scoring system used for the answers to the questions is the Lickert scale with 5 possible answers (none = 0; minimal = 1; moderate = 2; severe = 3; extreme = 4). Visual Analogue Scale for the evaluation of knee osteoarthritis-related pain for the index knee experienced over the last eight days. The scale is presented as a 10 cm horizontal line, the left end (= 0 cm) corresponding to no pain and the right end (= 10 cm) to the maximum imaginable pain. This outcome will be evaluated in the Larytherm cohort and compared to the control group of the Thermarthrose study.
Secondary Outcome Measures
- Relative change from baseline in the WOMAC functional subscale index at the end of the spa therapy and at 6 months after the end of the spa therapy. [Baseline, end of spa therapy (week 3) and 6 months after the end of spa therapy]
WOMAC index (functional subscale): functional assessment index for knee osteoarthritis, exploring the daily function. The scoring system used for the answers to the questions is the Lickert scale with 5 possible answers (none = 0; minimal = 1; moderate = 2; severe = 3; extreme = 4).
- Relative change from baseline in the WOMAC index (full questionnaire) at the end of the spa therapy and at 6 months after the end of the spa therapy. [Baseline, end of spa therapy (week 3) and 6 months after the end of spa therapy]
WOMAC index (full questionnaire): functional assessment index for knee osteoarthritis, exploring three areas of analysis: pain, stiffness and daily function. The scoring system used for the answers to the questions is the Lickert scale with 5 possible answers (none = 0; minimal = 1; moderate = 2; severe = 3; extreme = 4).
- Relative change from baseline in the knee osteoarthritis pain measured by the Visual Analogue Scale (VAS) for pain at the end of the spa therapy and at 6 months after the end of the spa therapy. [Baseline, end of spa therapy (week 3) and 6 months after the end of the spa therapy]
Visual Analogue Scale for the evaluation of knee osteoarthritis-related pain for the index knee experienced over the last eight days. The scale is presented as a 10 cm horizontal line, the left end (= 0 cm) corresponding to no pain and the right end (= 10 cm) to the maximum imaginable pain.
- Relative change from baseline in fatigue measured by the Visual Analogue Scale (VAS) for fatigue at the end of the spa therapy and at 6 months after the end of the spa therapy. [Baseline, end of spa therapy (week 3) and 6 months after the end of spa therapy]
Visual Analogue Scale for the evaluation of fatigue on the day of filling out the self-questionnaire.The scale is presented as a 10 cm horizontal line, the left end (= 0 cm) corresponding to no fatigue and the right end (= 10 cm) to the maximum imaginable fatigue.
