How different types of low back pain affect function and quality of life in people with ankylosing spondylitis.

The Impact of Low Back Pain Phenotypes on Pain Intensity, Functional Status, and Quality of Life in Patients With Ankylosing Spondylitis

Konya Beyhekim Training and Research Hospital · NCT07510789

This single-visit project will see if different types of low back pain in adults with ankylosing spondylitis relate to pain severity, daily function, and quality of life.

What this trial studies

This prospective, hospital-based study will enroll 200 adults with ankylosing spondylitis and chronic low back pain of at least three months, recruited consecutively from the Physical Therapy and Rehabilitation outpatient clinics at Konya Beyhekim Training and Research Hospital. Each participant will complete a standardized, single-session evaluation including questionnaires for pain intensity (VAS), pain catastrophizing (PCS), functional status (RMDQ), disease activity and function (BASDAI, BASFI), and quality of life (ASQoL). Sociodemographic and clinical data will be collected by structured interview, and pain mechanisms will be classified into three categories using validated tools. The analysis will examine how pain phenotypes and their cognitive-emotional components relate to functional status and quality of life.

Who should consider this trial

Good fit: Adults aged 18 or older with a diagnosis of ankylosing spondylitis and chronic low back pain lasting at least three months, who can communicate and attend a single clinic visit, are ideal candidates.

Not a fit: Patients younger than 18, those with major psychiatric illness, communication barriers, other non-ankylosing-spondylitis causes of back pain, or who require active treatment interventions are unlikely to receive direct benefit from participation.

Why it matters

Potential benefit: If successful, the results could help clinicians tailor pain management by identifying pain types linked to worse function and quality of life in ankylosing spondylitis.

How similar studies have performed: Questionnaire-based studies have previously linked pain characteristics to function in inflammatory back pain, but comprehensive phenotyping that includes cognitive-emotional features in ankylosing spondylitis is relatively novel.
