Clinical Trial Summary

1. Primary outcome measure: measuring the effect of spa treatment in patients suffering from lower limb osteoarthritis or any other lower limb rheumatological condition.

Percentage of patients with minimum 19,9 mm decrease in pain Visual Analogue Scale (VAS) or WOMAC score (Western Ontario and McMaster Universities Arthritis Index) improvement of at least 9 points (minimal clinically important difference), 6 months after enrollment.

Secondary outcome measures:

2. Measuring the effect of spa treatment in patients with concomitant chronic lower back pain.

Percentage of patients presenting clinical benefits according to the EIFEL score, with a decrease of at least 5 points, 6 months after enrollment.

3. Quantitative evaluation of pain. Mean pain VAS comparison between enrollment and 6 months after spa treatment.

4. Quantitative evaluation of WOMAC score. Mean WOMAC score comparison between enrollment and 6 months after spa treatment.

11. Auto-evaluation of pain VAS pain evaluation by the patient every 6 weeks for a more precise time frame of the treatment's effect.

Description:

Osteoarthritis and rheumatic conditions in general are a major public health issue, notably causing chronic pain disorders.

Spa treatments currently play a central role in the non-medical therapeutic arsenal for patients suffering from these rheumatic diseases.

A French study estimated the direct costs generated by osteoarthritis in France up to 1,6 billion euros in 2002, half of which was due to hospital expenses (800 million euros). Osteoarthritis required 13 millions consults and drug expenses of 570 million euros. Compared to 1993, these expenses increased by 156% due to the raise of the number of patients treated (+54%) and of the cost for each patient (+2,5% per year). This study concerned patients with lower limb osteoarthritis, and a significant portion of these expenses were attributable to the disease.

Chronic lower back pain is also a major health issue for its impact on patients' functional capacities as well as for the economic and social costs it generates. This is a frequent condition, it is estimated that 80% of the population will present lower back pain at some point in their life. Furthermore, epidemiological studies show an increase in the prevalence of lower back pain (3,9% in 1992 to 10,2% in 2006 in the American population).

Different well-conducted studies around the impact of spa treatments have led to the recognition of its beneficial outcome on the treatment of chronic lower back pain.

Several controlled, randomized, prospective trials have already evaluated the effect of spa treatment for other main indications claimed by crenotherapy in rheumatology such as hip and hand osteoarthritis, fibromyalgia, rheumatoid polyarthritis, psoriatic arthritis and chronic neck pain.

The THERMARTHROSE study by Forestier demonstrated the efficacy of spa treatments as a rheumatological indication for knee osteoarthritis using the WOMAC questionnaire and VAS pain scale. Following the model of this study, the investigators chose to use the WOMAC and VAS pain scale as the primary endpoints of the investigator's study.

The WOMAC questionnaire was developed by Bellamy in 1988, it is a functional index centered on the locomotor system.

The pain VAS is an auto-evaluation tool derived from visual analogue scales developed in psychiatry to measure patients' well-being. Today, this statistically measurable and reproductible tool is commonly used in clinical trials to monitor the evolution of pain and more precisely to evaluate the impact of a treatment on a given chronic disease such as osteoarthritis. For this study, pain will be measured using pain VAS according to Huskinsson and following methodology as recommended by French health authorities, with one measure.

During clinical studies in thermal environment, spa treatment is a composite entity including the effect of the water itself, but also physiotherapy, rest, education… The spa of Contrexéville wishes to obtain a new rheumatic indication. According to the recommendations of the Academy of Medicine, a prolonged observation of a cohort with repeated measures is required for any spa wishing to acquire the accreditation for a new orientation.

Towards this aim, the investigators wish to undertake a prospective study with repeated measures in order to analyze the evolution of the clinical state of patients with a rheumatic disease on the lower limbs or the rachis, 6 months after receiving a spa treatment in the Contrexéville thermal institute. Since rheumatological treatments at Contrexéville are not covered by health insurance, they will not be billed to the patients.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Effect of spa treatment on lower limb osteoarthritis	Percentage of patients with a WOMAC score improvement of 9 or more points and/or with a decrease in VAS of at least 19,9 mm (minimal clinically important difference)	At 6 months
Secondary	Effect of spa treatment on lower back pain	Percentage of patients with an EIFEL score decrease of at least 5 points	At 6 months
Secondary	Quantitative evaluation of pain	Comparison of mean VAS (Visual Analogic Scale from 0 to 10) pain scale	At baseline and 6 months
Secondary	Quantitative evaluation of WOMAC	Comparison of mean WOMAC questionnaire	At baseline and 6 months
Secondary	Quantitative evaluation of EIFEL	Comparison of mean EIFEL questionnaire	At baseline and 6 months
Secondary	Patient BMI	BMI evolution will be recorded (size, weight)	At baseline, 3 and 6 months
Secondary	Global quality of life	SF36 (The Short Form (36) Health Survey) questionnaire will be recorded. The SF36 questionnaire includes 36 questions from which eight dimensions and two aggregate scores (the physical dimension and the psychic dimension) are calculated. The correction of the missing data and the different methods of adjustment and calculation of the scores will be carried out according to the procedure recommended by the manual. The scores of the different dimensions range from 0: less good health and 100: the best.	At baseline, 3 and 6 months
Secondary	Health quality of life	EQ5D questionnaire will be recorded. EQ-5D is a standardized instrument developed by the EuroQol Group as a measure of health-related quality of life that can be used in a wide range of health conditions and treatments. The EQ5D has 6 items intended to measure general health. The top 5 rate mobility, independence, daily activities, pain / discomfort, and anxiety / depression, and are rated according to 3 values from "No problem" to "Problem" or "Incapacity". This results in an index score. The last item deals with perceived health on the day the questionnaire is filled in and uses a visual analogue scale from 0 (worst) to 100 (best health possible) (Visual Analog Scale Score).	At baseline, 3 and 6 months
Secondary	Doctor / patient opinions	Semi-quantitative scale in 7 points collected will be recorded. This is a semi-quantitative evaluation of the effect of the cure on the state of health of the patient by the patient himself and the same questions by the doctor. Responses will be grouped into 3 classes: aggravated / neither aggravated nor improved / improved. The numbers and percentages of each answer will be calculated	At baseline, 3 and 6 months
Secondary	Treatment follow-up	Description of treatments consumption by the patient at baseline, 3 and 6 months. To avoid any risk of confusion, drug consumption will be related to daily consumption. Drug use for 72 hours (day before and before the day of visit, day of visit: d-2, d-1, D0)	At baseline, 3 and 6 months
Secondary	Self evaluation of pain	Visual Analogic Scale (from 0 to 10) evaluation by patients	With investigator at baseline, 3 and 6 months. Auto evaluation at 1.5 months and 4.5 months.
