Official title
Determination of Pain Phenotypes in Older Adults With Knee Osteoarthritis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Recently, the medical community has learned damage to the knee joint may be one of many possible reasons for pain in knee osteoarthritis. Psychological factors and other aspects of brain function seem to play an important role in the pain experience. Although research studies have examined these factors on an individual basis, no study has examined all of these factors in the same population. Furthermore, some measures of brain function- having to do with perception of the painful body part- have yet to be examined in knee osteoarthritis. The investigators plan to study many of these variables in a group of people with knee osteoarthritis, as well in some healthy controls (without knee pain), in order to establish the relative importance of these measures in contributing to pain, as well as validate new measures of perception in people with knee osteoarthritis. We also plan to use a statistical tool- known as latent profile analysis- to look at subgroups of knee osteoarthritis pain. The hypothesis is that different people experience pain in knee osteoarthritis for different reasons. This study will be the first study to use all of these different variables- which can be reproduced in a clinical setting- to look for different subgroups of knee osteoarthritis pain. Ultimately, the goal is to help clinicians better prioritize and target interventions to individual patients. The investigators believe this will lead to better outcomes and fewer treatment complications currently associates with pharmaceutical and surgical interventions that are widely used to treat knee osteoarthritis.
