The intensity of pain over the last 48 hours will be assessed by the patient at each visit on a visual analogue scale (VAS). EVA pain (visual analogue scale over 100 mm): one-dimensional measurement of the intensity of pain. EVA pain is a continuous scale consisting of a horizontal line from 0 (no pain) to 100 mm (maximum pain)

The activity of the disease over the last 48 hours will be evaluated at each visit by the patient and the doctor on a visual analog scale from 0 (no pain) to 100 mm (maximum pain)

The aesthetic impact of osteoarthritis of the hands will be evaluated at each visit by the patient on a visual analog scale from 0 (no pain) to 100 mm (maximum pain)

The impact on pain and function measured by the AUSCAN questionnaire. This is a functional index including 15 questions with a specific orientation to osteoarthritis of the hands, assessing pain / stiffness and function. The score varies from 0 to 60. Fill in the questionnaire: 7 min

The impact on pain and function measured by the COCHIN functional index wich is oriented towards AD. It includes 18 questions, ranging from 0 to 5, and is particularly interested in the impact of osteoarthritis of the hands on the daily activities (cooking, clothing, hygiene, office ...) of the patient. The score varies from 0 to 90. Questionnaire filling time: 5 min

The impact on pain and function measured by a 6-minute walk test that characterizes an overall assessment of functional ability to exercise. The patient is asked to walk as much as possible for 6 minutes (round trip in a 30m corridor), the pace of walking is freely chosen (ATS Recommendations, 2002)

The short version with 7 questions will be used

The WPAI questionnaire is an instrument for measuring deficiencies in paid work and unpaid work over the last 7 days. It measures absenteeism, presenteeism as well as the deficiencies of unpaid activity due to a health problem. It contains 6 questions and has already been used during AD

The Health Assessment Questionnaire (HAQ) is a measure of quality of life in health. The questionnaire is designed to be completed by the patient himself, without the help of a doctor. We will use an adaptation of the HAQ, the Modified Health Assessment Questionnaire (MHAQ), as in the Kwok et al. Study, with 8 questions about the function of the hand. The score ranges from 0 to 3. The average score reported in osteoarthritis studies is 0.8. It is 0.49 in the global population.

The SF-36 questionnaire assesses the quality of life. It is a validated international questionnaire. It consists of 36 items evaluating 8 dimensions. It can be used in health economics studies as a variable in the calculation of a Quality Adjusted Life Year (QALY) to determine the cost-effectiveness of a health intervention. Fill in the questionnaire: 10 min.

This score varies between 0 and 1: 0 represents death, and 1 the best quality of life possible. So, this score indicates the decrease in quality of life compared to an optimal state of health. The more desirable a health state, the higher the score associated with it. Negative scores are possible if the subject perceives a state of health worse than death. The EQ-5D-3L includes the following five dimensions: mobility, self-care, usual activities, pain / discomfort, and anxiety / depression. Each dimension has 3 levels: absence of problems, presence of problems and extreme problems. Questionnaire filling time: 5 min

It is an international questionnaire validated with 6 items, which assesses the aesthetic impact of osteoarthritis of the hands. The questionnaire includes the function of the overall hand, the activities of daily life, the pain, the work, the appearance of the hands and the satisfaction of the patient with the functionality of his hands. In the ladder pain, a high score indicates more intense pain, while in the rest of the items, a better score reveals better hand functionality. Duplicate filling time: 15 min.

This questionnaire assesses the psychological impact of the patient. It consists of 14 questions with 4 possible answers. This score makes it possible to differentiate a level of anxiety and a level of depression according to the answers. Each sub-scale varies from 0 to 21. Questionnaire filling time: 5 min

The aesthetic impact of osteoarthritis of the hands will be evaluated at each visit by the patient with the help of the Michigan Hand Outcome Questionnaire. It is an international questionnaire validated with 6 items, which assesses the aesthetic impact of osteoarthritis of the hands. The questionnaire includes the function of the overall hand, the activities of daily life, the pain, the work, the appearance of the hands and the satisfaction of the patient with the functionality of his hands. In the ladder pain, a high score indicates more intense pain, while in the rest of the items, a better score reveals better hand functionality. Duplicate filling time: 15 min (MHQ)
