Official title
Epidemiology of OA Pain
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Chronic pain, by definition, persists over long periods of time, but both sufferers of pain and their caregivers are aware that pain levels can fluctuate greatly over time. Being able to define pain variability and its underlying causes would be an important advance in our understanding of chronic pain, and would in turn lead to better approaches to the treatment of chronic pain. In this study, the investigators propose to evaluate in 60 people with chronic pain of the knee due to osteoarthritis over 3 months, collecting data regarding magnitude of pain, physical activity level, and medication status twice daily during this period of time. The investigators then will assess the variability in pain levels over time, the frequency of "flares" of osteoarthritis (OA) pain and their relationship to physical activity, medications, and clinical descriptors of the population, e.g., age, gender, body mass index (BMI). Additionally, evaluations will be made regarding temporal patterns of OA knee pain as well as assessment of subgroups of patients with the overall group being studied.
