Evaluation of Physical Performance in Ankylosing Spondylitis Patients

Ankylosing spondylitis (AS) can cause serious limitations in individuals' physical performance, as it involves the musculoskeletal system and can cause ankylosis and arthritis in both axial and peripheral joints. Although there are many studies showing these limitations nowadays, there is a need to show these limitations with more objective data with the new technology. Evaluating aerobic physical capacity; Cardiopulmonary Exercise Test (KPET) is frequently used in physical performance analysis today. In this study, the investigators want to observe the physical performance differences between 42 AS patients and 42 control group participants by applying KPET and present the expected performance losses in AS patients in the literature with objective data.
