Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

* The first group: treatment-naïve patients with ankylosing spondylitis (AS), who fulfil the Assessment of Spondylarthritis Society (ASAS) criteria for axial spondyloarthritis (ax-SpA) * The second group (non-AS individuals) : patients complaining of discomfort upon activity.

You may qualify if:

  • treatment-naïve patients with ankylosing spondylitis (AS), who fulfilled the Assessment of Spondylarthritis Society (ASAS) criteria for axial spondyloarthritis (ax-SpA)

You may not qualify if:

  • patients with a history of local trauma
  • and/or surgical intervention,
  • neuromascular deficits,
  • chronic chest disease and
  • other inflammatory autoimmune/rheumatologic conditions.
  • a history of AS or
  • other systemic autoimmune/ rheumatologic disease.
