Educational Program Associated With a Conventional Spa Therapy of Knee Osteoarthritis Patients (GETT2)

Intervention: 7 educational workshops in addition to spa therapy :

Knowledge of the pathology ; Educational physical activity ( 2 workshops); Dietary; Management of pain, fatigue and the medical treatments; Articular hygiene and ergonomics; Technical assistance, an adaptation of the living condition

Average change from effectiveness of the educational workshops, personalized and determined for every patient, measured by a GAS GAS (Goal Attainment Scaling in Rehabilitation) is a method of scoring the extent to which patient's individual goals are achieved in the course of intervention. In effect, each patient has their own outcome measure but this is scored in a standardized way as to allow statistical analysis.

Each goal is rated on a 5-point scale, with the degree of attainment captured for each goal area:

• If the patient achieves the expected level, this is scored at 0.
• If they achieve a better than expected outcome this is scored at: +1 (more than expected), +2 (much more than expected)
• If they achieve a worse than expected outcome this is scored at: -1 (less than expected) or -2 (much less than expected) GAS depends on two things - the patient's ability to achieve their goals and the clinician's ability to predict outcome, which requires knowledge and experience.

Score on WOMAC

The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of Hip and Knee Osteoarthritis. It is a questionnaire consisting of 24 items divided into 3 subscales:

Pain (5 items), stiffness (2 items), physical Function (17 items). The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4).

The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. Usually a sum of the scores for all three subscales gives a total WOMAC score, however there are other methods that have been used to combine scores.

Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.

Average change from baseline of the comprehensive evaluation of patient education programs , measured by a HEIQ.

The Health Education Impact Questionnaire (heiQ): an outcomes and evaluation measure for patient education and self-management interventions for people with chronic conditions.

There are 8 sections: dressing, arising, eating, walking, hygiene, reach, grip, and activities. There are 2 or 3 questions for each section. Scoring within each section is from 0 (without any difficulty) to 3 (unable to do). For each section the score given to that section is the worst score within the section, i.e. if one question is scored 1 and another 2, then the score for the section is 2.
