Prevalence and Characteristics of Widespread Pain in People With Knee Osteoarthritis

Sponsor: Vastra Gotaland Region

Summary

The goal is to evaluate whether the number of pain sites or pain estimation with Instant and Constant Osteoarthritis Pain (ICOAP) is related to functional impairment in the lower extremity in people with knee osteoarthritis (KOA). The main questions it aims to answer are: 1. What is the relationship between the number of pain sites and physical function when adjusted for age, sex, education level, and origin in people with KOA? 2. What is the relationship between pain experience measured with ICOAP (constant and intermittent pain subscales, as well as total score) and reduced physical function when adjusted for age, sex, education level, and origin in people with KOA? 3. What is the relationship between demographic data (age, sex, BMI, origin, level of education) and reduced physical function in people with KOA? Participants were recruited from five rehabilitation clinics in primary care within the Västra Götaland region, for another study (NCT03855813). Patients with diagnosed KOA were asked to participate in the study. The patients mostly had problems in the knee joint but could also have osteoarthritis (OA) in other joints.
