The study is a single arm interventional study with a treatment phase of 6 months.

Patients included in this single group study will have 3 interventions to assess the severity of muscle loss :
dynamometry exam
walking test
Dual-energy X-ray Absorptiometry (DXA) measurement Quality of life will be assessed with Sarcopenia & Quality of Life (SARQOL) questionnaire. Patients will also fill a Life habits Questionnaire.

Spondylarthropathy

Sarcopenia

Prehension strength of the main hand will be assessed thanks to dynamometry, in order to evaluate patient's muscular strength

Dynamometry exam

A 4 metres walking test will be performed to assess patient's walking speed

Walking test

DXA measurement will be performed to assess patient's body composition

DXA measurement

Patient's quality of life will be assessed thanks to the SARQOL questionnaire

SARQOL questionnaire

Life habits Questionnaire

Service de Rhumatologie - Hôpital Edouard Herriot

Sarcopenia in Axial and Peripheral Spondyloarthropathies

Muscular strength is the first outcome to evaluate sarcopenia

Walking speed is a physical performance outcome, that is the second outcome to evaluate sarcopenia

Muscular mass is the third outcome to evaluate sarcopenia and will be assessed using DXA

Number of hours of sport practice per month is the first outcome to evaluate patient's global physical activity.

Physical activity rate in work can be light, medium, high or not applicable if the patient does not work ; it is the second outcome to evaluate patient's physical global activity.

Average walking time in a week is the third outcome to evaluate patient's physical global activity.

Quality of life will be assessed thanks to the SARQOL questionnaire (score between 0 and 100)

inflammatory bone marrow edema lesions and fatty lesions and the anterior and posterior corners of the spine (Berlin score) as well as for the presence of enthesitis on the posterior elements.
The sacroiliac joints will also be scored according to the Berlin scoring method for the presence of acute and structural inflammatory lesion, including BME, fat metaplasia, erosions, sclerosis, ankylosis. Anterior and posterior extraarticular enthesitis will also be registered

Other researchers are expected to perform the study in their own countries. If they perform the study, unidentified data from the present study will be processed with the other parties data.
