Osteoarthritis (OA) is a common articular conditions among adults ≥60 years of age,
with OA of the knee and hip resulting in significant chronic disability.1 The economic effect of OA is high as a consequence of lost productivity at work,
the cost of treatment, and the frequent need for patients to adapt their lives and
environment because of the disease.2 Because joint pain is a primary symptom of OA, it is important for clinicians to
monitor the occurrence and intensity of joint pain in patients with OA. The Measure
of Intermittent and Constant Osteoarthritis Pain (ICOAP) is an 11-item patient-reported
outcome measure that measures intermittent (6 items) and constant (5 items) pain among
patients with OA. The assessment includes separate versions for the hip and knee joints.
Items are scored using a 0 to 4 scale, with 0 representing no pain and 4 representing
extreme pain.3 The ICOAP does not require any formal training, is free to use, and only requires
the evaluation form and a writing utensil. Additionally, the ICOAP has been cross-culturally
validated in >9 different languages.4 The ICOAP demonstrates excellent test-retest reliability,3., 5. internal consistency,3., 6. and convergent validity with similar instruments that assess osteoarthritis pain.3 A Rasch analysis indicated the ICOAP is a unidimensional measure of pain.7
