To assess the effects of clinical Pilates training on disease-specific indices, core stability, and balance in ankylosing spondylitis (AS) patients.


AS patients were randomly assigned to either the Pilates group (PG) or control group (CG). The PG participated in Pilates training 3 times a week for 8 weeks. Patients in the CG were instructed to follow a home exercise program for 8 weeks. Assessments were performed before and after the interventions. BASDAI, BASFI, BASMI, and the AS Quality of Life (ASqOL) questionnaire were used were used to evaluate disease activity, functionality spinal mobility and quality of life respectively. Static core endurance was assessed with trunk flexor, extensor endurance, and lateral bridge tests, while dynamic core endurance was assessed using modified sit-up test. Balance was evaluated with bilateral and unilateral stance static postural stability (PS), bilateral stance dynamic PS and limits of stability (LOS) tests using the Biodex Balance System.


Twenty-one patients in the PG and 21 patients in the CG completed the study. PG showed statistically significant improvements in BASDAI, BASFI, BASMI, and ASQoL scores, all core endurance tests, and dynamic PS and LOS results. The CG demonstrated significant improvement only in flexor endurance and LOS results. Post-intervention BASDAI, BASMI, and all core endurance tests were significantly better in the PG than in the CG (p < 0.05).


Pilates training has positive effects on disease activity and functional capacity, spinal mobility, core endurance, balance, and quality of life in ankylosing spondylitis patients.
