Evidence summary (Updated 2022)
Restrictive pulmonary function is more prevalent in people with ankylosing spondylitis (1). A recent systematic review (included 3 published RCTs and 5 controlled trials) on the effectiveness of different exercise types on cardiopulmonary function showed improvements on pulmonary capacity with multiple interventions (2). These included global posture retraining, inspiratory muscle training, swimming and walking. The majority of trials showed improvement in outcome scores, specifically spirometry measurements and chest expansion (2). The recommended best approach was found to be specific pulmonary respiratory muscle training exercises in combination with physical activity.
Quality of evidence
Grade B – Moderate quality
Strength of recommendation
Grade 1 – Strong recommendation for ankylosing spondylitis
Keeping active and performing regular exercise has been shown to improve pulmonary capacity for people with ankylosing spondylitis. The best approach may be to consider specific pulmonary respiratory muscle training exercises in combination with physical activity.
