The National Axial Spondyloarthritis Society (NASS), formerly known as the National Ankylosing Spondylitis Society, is the UK’s leading charity and support organisation dedicated to people affected by axial spondyloarthritis (axial SpA), including ankylosing spondylitis. It plays a key role in improving awareness, diagnosis, treatment, and long-term management of this inflammatory spinal condition.

NASS works closely with healthcare professionals, including physiotherapists, to promote early diagnosis and evidence-based management strategies. A major focus of the organisation is the importance of exercise and physiotherapy-led management in improving function, reducing pain, and maintaining spinal mobility for people living with axial SpA.

The organisation provides a wide range of educational resources, clinical guidance, and patient information that can support both clinicians and patients. It also offers training opportunities, webinars, and events designed to improve understanding of the condition and encourage best practice in rehabilitation and long-term care.

In addition to its educational role, NASS is heavily involved in advocacy and awareness campaigns. It works to reduce delays in diagnosis, improve access to specialist care, and ensure that patients receive appropriate multidisciplinary support throughout their condition.

NASS also facilitates a strong community network, connecting patients, clinicians, and researchers to share knowledge and lived experience. This collaborative approach helps to shape better services and improve outcomes for those affected by axial SpA.

Overall, NASS is a key organisation for physiotherapists working in musculoskeletal and rheumatology settings, offering valuable resources, clinical insight, and support for the effective management of axial spondyloarthritis.
