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).
