Evaluation of Spine Posture, Trunk Position Sense and Gait in Axial Spondyloarthritis Patients

Axial Spondyloarthritis (Ax-SpA) are chronic systemic inflammatory rheumatological diseases characterized by axial skeletal involvement and enthesitis. Sacroiliitis is the most prominent sign of the disease. The International Society for the Evaluation of Spondyloarthritis created a new classification for Ax-SpA in 2009. According to this classification, Ax-SpA; It is divided into two groups as ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA).

With the emergence of the term nr-axSpA, studies have begun to compare AS and nr-axSpA in terms of genetic, epidemiological and clinical features, treatment needs and response to treatment.However, more studies are needed to better understand the clinical features and symptoms of nr-axSpA patients.

The aim of this study was to determine the clinical features of patients with nr-axSpA and AS; To evaluate spine posture, trunk position sense and gait parameters, and also to compare these results with healthy individuals.

There are no studies comparing spine posture, trunk position sense and gait parameters in patients with nr-axSpA and AS. It is important to determine the changes that occur in nr-axSpA patients in the early period. At the same time, taking the necessary precautions and following these patients with the rehabilitation process can ensure that the radiographic development is delayed or not at all in the future.

Hypotheses:

H1: Trunk position sense is different from each other in individuals with Nr-axSpA and AS.

H2: Spatio-temporal features of gait are different in individuals with Nr-axSpA and AS.

H3: Plantar pressure distribution is different in individuals with Nr-axSpA and AS.

The Location of the Research: The research is carried out in Konya Necmettin Erbakan University Meram Faculty of Medicine, Rheumatology Department. After obtaining the permission of the ethics committee, official permission was obtained from Necmettin Erbakan University Meram Medical Faculty Hospital Chief Physician to conduct the study.
