Video Coaching of Physical Activity in Axial Spondyloarthritis

Study Overview
=================
Brief Summary
-----------------
The primary objective of the study is to demonstrate the beneficial effect of a 3 months home-based physical exercise program supervised by online videos, in addition to the usual recommendations, in comparison with usual physical activity as recommended by the WHO. The secondary objectives of the study are : to compare the following criteria between 2 groups at 3 and 6 months: quality of life; other measures of disease activity ; sleep quality ; walking ability muscle strength of; professional activity; cost of cares; evolution of weight, BMI and waist. to evaluate the observance of physical activity program and its tolerance at 3 and 6 months.

Detailed Description
-----------------
The spondyloarthritides are a group of inflammatory rheumatic diseases, including ankylosing spondylitis, reactive arthritis, inflammatory bowel disease-related rheumatic disease, and psoriatic arthritis. The frequence of axial spondyloarthritis is 0.41% in the french population. This disease is associated with a reduction of physical capacities and quality of life. NSAIDs or even biologic therapies do not always permit a sufficient control of the disease. Different physical exercise programs can be effective as an additional therapy for spondyloarthritis, with positive effects on spinal mobility as well as main disease activity and functional indices (BASDAI, BASFI and BASMI). The severity of the disease does not seem to influence significantly the patients' motivation in practicing physical activity. This proposed study aims to demonstrate the beneficial effect of physical exercises coached with a specific internet program diffused on a secured platform. Each patient will have to connect 3 times weekly in order to follow the entire program. The impact will be evaluated at 3 months and 6 months. Potential impacts of video-coaching program are: reduction of the intrinsic inflammatory activity of the rheumatic disease; improvement of the global physical condition: muscular strength and resistance, walking ability, chest expansion; reduction of fatigue and improvement of sleeping; reduction of consumption of symptomatic drug (analgesics, NSAIDs, corticosteroids).
