About this study

Ankylosing spondylitis (AS) is a painful and progressive chronic inflammation of the axial skeleton, mainly affecting the vertebral and sacroiliac joints. The management of AS aims to improve and maintain spinal mobility and normal posture, alleviate symptoms, reduce functional limitations and minimise complications. Due to the characteristic features of the disease, recommended spinal mobility exercises and aerobic exercises focus on reducing symptoms, improving functional capacity and quality of life, and improving and maintaining spinal mobility. Calprotectin, visfatin, leptin can be evaluated as biomarkers in inflammatory rheumatic diseases as an alternative to acute phase proteins and may reflect disease activity.

This study was designed as a prospective randomised controlled trial. Participants will be randomized into 2 groups and the intervention group will be given aerobic exercise and stretching exercise, and the other group only stretching exercise. BASDAI, BASMI, BASFI, ASQOL, ASDAS-CRP, Chest Expansion, 6 Minute Walk Test and Borg Scale will be used as assessment parameters.

Calprotectin, Visfatin, Leptin, IL-33 serum levels will be analysed by ELISA kit with blood samples taken in the early morning at the beginning of treatment, at the end of treatment (4th week) and at the 12th week after the beginning of treatment.

Treatment and study plan

Aerobic exercises with cycling ergometry

Device

A total of 20 sessions of high-intensity interval (HIIT) aerobic exercise program will be applied to the patients using a bicycle ergometer, five days a week and once a day for four weeks. And then, it was planned to perform stretching exercises for the cervical, thoracic and lumbar regions and posture exercises accompanied by a specialist physiotherapist.

The patients will be evaluated by the physician for a total of 3 times at the beginning of the treatment, at the end of the treatment (4th week) and at the 12th week after the start of the treatment. All patients will be evaluated for the parameters in the patient evaluation form, and blood samples taken between 08:00 and 10:00 in the morning and Calprotectin, Visfatin, Leptin, IL-33 serum levels will be measured with the ELISA kit.

Primary outcomes

  1. Change in BASDAI

    Time frame: Baseline, after 4 and 12 weeks

    The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) consists of 6 questions about disease activity. Each question is scored on a scale of 0 to 10. High scores means high disease activity. It is a reliable and sensitive to changes index developed to assess disease activity and progression.

Secondary outcomes

  1. Change in BASMI

    Time frame: Baseline, after 4 and 12 weeks

    The Bath Ankylosing Spondylitis Metrology Index (BASMI) is related to the spinal mobility of patients with ankylosing spondylitis. It consists of 5 clinical measurements. The total score of 5 measurements is obtained, the score range is between 0-10, a lower score means better spinal mobility.

  2. Change in BASFI

    Time frame: Baseline, after 4 and 12 weeks

    The Bath Ankylosing Spondylitis Functional Index (BASFI) is a sensitive and reliable index developed for the determination and follow-up of functional status in patients with AS. It consists of 10 questions evaluating the functions of the patients. The final score is obtained by dividing the total score by 10 using the VAS in the range of 0-10 cm for each question. A high score indicates poor function.

  3. Change in ASQOL

    Time frame: Baseline, after 4 and 12 weeks

    The Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL) is the most widely used questionnaire to assess quality of life in AS, and it is valid and reliable. In this questionnaire consisting of eighteen questions, patients are asked to answer yes or no to each question. The total score varies between 0-18. High scores indicate serious deterioration in quality of life

  4. Change in ASDAS-CRP

    Time frame: Baseline, after 4 and 12 weeks

    The Ankylosing Spondylitis Disease Activity Score-CRP (ASDAS-CRP) consists of four questions and the acute phase reactants CRP mg/L result. ASDAS-CRP will be calculated together with the CRP result in the formula. Mild disease activity <1.3 Moderate disease activity 1.3-2.1 High disease activity 2.1-3.5 Very high disease activity >3.5

  5. Change in Chest Expansion

    Time frame: Baseline, after 4 and 12 weeks

    Chest expansion is determined by measuring the chest circumference following a deep inspiration and forced expiration. The expansion of the chest circumference is recorded in centimetres.

  6. Change in 6 Minute Walk Test

    Time frame: Baseline, after 4 and 12 weeks

    The 6 Minute Walk Test is a sub-maximal exercise test used to assess aerobic capacity and endurance. The score of the test is the distance a patient walks in 6 minutes.

  7. Change in Borg Scale

    Time frame: Baseline, after 4 and 12 weeks

    The Borg scale is a numerical expression of the verbal expression of exercise intensity in patients undergoing cycle ergometry. It allows direct comparison of individuals. 6 to 20 are evaluated. The Borg scale is a numerical expression of the verbal expression of exercise intensity in patients undergoing cycling ergometry. It allows direct comparison of individuals. 6 to 20 are evaluated. As the activity becomes more difficult for the patient, the values given increase.
