“…Previously, only static or dynamic balance were assessed in AS patients. [5][6][7] However, we were unable to detect any trial in the literature assessing both static and dynamic balance in AS patients. Therefore, factors affecting balance in AS patients are still unclear.…”

Objectives:This study aims to compare ankylosing spondylitis (AS) patients with healthy subjects in terms of posture and balance, and to identify the factors correlated with balance in AS. Patients and methods: Thirty patients (17 males, 13 females; mean age 41.7±7.7 years; range 31 to 57 years) with AS and 33 healthy subjects (18 males, 15 females; mean age 41.3±7.0 years; range 26 to 56 years) were included in the study. Participants were assessed in terms of posture and balance. Posture was assessed using tragus-wall distance, modified Schober's test, and chest expansion. Balance was assessed using device-assisted balance tests. Pain (visual analog scale) and disease activity (Bath Ankylosing Spondylitis Disease Activity Index) were assessed only in AS patients. Results: Ankylosing spondylitis patients walked more slowly when compared to healthy subjects (p=0.002). As the modified Schober's test was restricted, AS patients had greater step width in tandem walk and higher sway velocity on foam base (r=-0.418 p=0.022; r=-0.473 p=0.008). Neither Bath Ankylosing Spondylitis Disease Activity Index nor visual analog scale was correlated with balance. Conclusion: Static and dynamic balance are impaired in AS patients when compared to healthy subjects. Restricted mobility of the spine and advanced kyphosis impaired balance, while pain and disease activity had no correlations with balance.

“…In the results of the study, a positive relationship was only found between the tragus-wall distance and the mediolateral stability index. No other relationship was determined between the BASMI score of other stability indexes and disease duration and it was therefore reported that there was a high probability of dynamic balance loss in AS [14].…”

“…In the first study in literature examining the relationship of AS and postural balance, Murray et al showed a higher rate of impaired balance in AS patients compared to healthy individuals [13]. However, in a later study, no impairment could be shown in the postural stability of AS patients [14].…”

“…In AS, the musculoskeletal system is affected, which is related to the motor responses of postural control and the other systems are intact. Muscle shortness, atrophy and joint restrictions cause reductions in joint range of movement and loss of joint flexibility and together these cause loss of balance and impairments in postural balance [13,14].…”

Ankylosing spondylitis (AS) is a chronic inflammatory disease characterised by inflammatory back pain and the formation of syndesmophytes which lead to ankylosis. Postural deviation in AS patients is caused by increased thoracic kyphosis and hip flexion which then causes the centre of body weight to shift anteriorally. As a compensation mechanism, knee flexion and plantar flexion develop. Although it has been estimated that the typical deformities which
