Description détaillée
Ankylosing Spondylitis (AS) is a systemic inflammatory disease that affects mainly the spine and compromises globally the physical capacity of the patients. Despite new advances in pharmacological therapy, physiotherapy and exercise remain essential in the treatment of AS. However, the literature lacks studies showing which types of exercises are more effective in patients with AS.
This is a randomized controlled trial with the objective is to evaluate the effects of aerobic training on functional capacity, mobility, disease activity, cardiopulmonary capacity and cytokine levels (TNF, IL10, IL6 and IL1) in patients with AS.
The duration of the trial is 24 weeks with the first 12 weeks reserved to exercise programs. The participants will be divided in two groups. The intervention group (IG) will perform walking for 50 minutes plus global stretching 3 times a week for 12 weeks. The control group (CG) will do only stretching exercises 3 times a week for 12 weeks.

Intervention / Traitement |
|---|---|
|
Expérimental: Aerobic training
The patients in this arm perform a 50-minute-walking at anaerobic threshold plus stretching exercises 3 times a week for 12 weeks.
|
The intervention comprises fifty minutes of walking at anaerobic threshold plus stretching exercises 3 times a week for 12 weeks.
Global stretching exercises will be performed for about 20 minutes 3 times a week for 12 weeks with supervision of specialized physiotherapists.

Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Change in BASFI
Délai: Baseline, after 6, 12 and 24 weeks.
|
Bath Ankylosing Spondylitis Functional Index (BASFI) is a quaestionnaire with 10 questions about functional capacity validated to AS patients.
Each question is answered with a visual analogue scale 0-10 cm.
Zero means the best, and 10 the worst function.
|
Baseline, after 6, 12 and 24 weeks.

|
Change in BASDAI
Délai: Baseline, after 6, 12 and 24 weeks.
|
Bath Ankylosing Spondylitis Disease Activity Score (BASDAI) is a instrument with 6 questions about disease activity validated to AS patients.
The questions comprise the following areas: back pain, peripheral pain, morning stifness, fatigue and enthesitis.
|
Baseline, after 6, 12 and 24 weeks.
|
|
Change in BASMI
Délai: Baseline, after 6, 12 and 24 weeks.
|
Bath Ankylosing Spondylitis Mobility Index (BASMI) is an instrument that comprises 5 measures of mobility validated to AS patients.
The measurements are: cervical rotation, lumbar flexion (Schober's test modified, intermalleolar distance, lumbar side flexion and tragus to wall.
The total score is shown in a 0-10 cm visual analogue scale.
The low scores represent better mobility.
|
Baseline, after 6, 12 and 24 weeks.
|
|
Change in HAQ-S
Délai: Baseline, after 6, 12 and 24 weeks.
|
Health Assessment Questionnaire for Spondyloarthritis (HAQ-S)is a questionnaire with 10 domains about functional capacity validated to AS patients.
The scores ranges from 0 to 3.
|
Baseline, after 6, 12 and 24 weeks.
|
|
Incremental cardiopulmonary exercise testing protocol by treadmill
Délai: Baseline and after 12 weeks.
|
Incremental cardiopulmonary exercise testing protocol by treadmill is used to measure aerobic capacity of the patients.
|
Baseline and after 12 weeks.
|
|
Levels of C reactive protein and erythrocyte rate sedimentation
Délai: Baseline, after 6. 12 and 24 weeks
|
CRP and ESR are laboratory methods to evaluate inflammatory response using blood sample.
|
Baseline, after 6. 12 and 24 weeks
|
|
Levels of cytokines- TNF, IL10, IL6 and IL1.
Délai: Baseline and after 12 weeks.
|
Cytokines are substances that make part of inflammatory response.
The most important cytokines- TNF alpha, IL10, IL6 and IL1 will be measured in serum samples.
|
Baseline and after 12 weeks.
|
|
Change in the Six minute walking test
Délai: Baseline, after 6, 12 and 24 weeks.
|
The 6-minute walking test is a instrument to evaluate functional capacity.
It is performed measuring the distance that the participant is able to walk during 6 minutes.
|
Baseline, after 6, 12 and 24 weeks.
