Brief Summary
It has been estimated that 300 million people worldwide have osteoarthritis (OA), and this has increased by 97% over the past 25 years. OA is degenerative joint disease that has joint cartilage break down and causes the surrounding bone to change and rub. The pain and loss of mobility experienced by people with knee OA can seriously reduce quality of life, while pain management causes significant healthcare spending. Unfortunately, the pain associated with OA is complex and difficult to treat other than to have a total knee replacement surgery to replace the damaged bone and surrounding tissues with artificial ones. Our research study plans to use advanced magnetic resonance imaging techniques and novel analysis methods to determine if specific parts of the brain are responsible for difficult to describe and diagnose aspects of chronic pain. This study will help us better understand the effects of chronic pain in the brain and the results will help guide future research into new therapeutic options that would focus on relieving the brain dysfunction caused by chronic pain.

Outcome Measures
Primary Outcomes (1)
Group and individual differences at baseline and post-intervention
The primary objective is to determine if chronic pain, more specifically chronic nociplastic pain, causes neuroplastic brain alterations. It is hypothesized that people with localized chronic pain (OA-Knee) and widespread chronic pain (OA-Knee+Body) would exhibit abnormal brain function (e.g., network connectivity and ROI complexity) and reduced microstructural integrity of brain white matter, that would also be proportionately associated with pain sensitivity and mental state, in comparison to similarly aged individuals with knee osteoarthritis without chronic pain.

Study Arms (3)
OA-PF
ACTIVE COMPARATORIndividuals with knee OA without knee or bodily pain. All participants will complete the same study protocol with pre- post-perturbation MRI scans and pain assessment questionnaires, as well as breath samples collected at multiple time points during the study visit.
OA-Knee
EXPERIMENTALIndividuals with knee OA with localized knee pain. All participants will complete the same study protocol with pre- post-perturbation MRI scans and pain assessment questionnaires, as well as breath samples collected at multiple time points during the study visit.
OA-Knee+Body
EXPERIMENTALIndividuals with knee OA with localized knee pain and widespread bodily pain. All participants will complete the same study protocol with pre- post-perturbation MRI scans and pain assessment questionnaires, as well as breath samples collected at multiple time points during the study visit.
Interventions
This test will allow the research team to induce a painful sensation in participants in a safe, non-invasive, standardized, and short-lasting manner. The protocol for the cold pressor gel test is simple: participants will place their non-dominant hand in the container of cold water for as long as they can up to a maximum of two minutes. If it becomes too painful or uncomfortable during those two minutes, participants can remove their hand from the container. It should be noted again that this is not a treatment for knee OA or chronic pain and will be used to investigate the effects of acute pain in the brain of individuals with a chronic pain condition.
Eligibility Criteria
You may qualify if:
- Clinical diagnosis and radiographic evidence of knee OA (by rheumatologist).
- For the two experimental groups (Groups OA-Knee and OA-Knee+Body), participants must have experienced chronic pain related to their knee OA (\>3 months) on most days of each month.
- Participants in Group OA-Knee+Body must:
- Exhibit chronic knee pain and widespread bodily pain at \>3 Michigan Body Map regions.
- Meet the Kosek criteria for nociplastic pain: i) the duration/regionality/type of pain, ii) history of hypersensitivities, iii) comorbidity identification, and iv) evoked pain hypersensitivity \[19\]
- Participants must be able to speak and understand English.
You may not qualify if:
- Unable to provide consent (e.g., poor English language skills, etc.)
- History of liver or kidney disease
- MRI contraindications:
- Pacemaker
