What this research studies

If you have moderate to severe knee arthritis pain, this project is looking for ways to personalize your pain treatment. Participants will receive either naproxen, duloxetine, or a placebo to see how each affects their pain. Researchers will collect various health information, including surveys, physical tests, blood samples, and brain and joint imaging, both before and after treatment. This helps us understand why certain treatments work better for some people than others. The goal is to find unique patterns that guide doctors to the most effective pain relief for each individual.

Who could benefit from this research

Good fit: Ideal candidates are individuals experiencing moderate to severe pain from knee osteoarthritis.

Not a fit: Patients without knee osteoarthritis pain or those not seeking new pain management strategies would not directly benefit from participating in this specific project.

Why it matters

Potential benefit: If successful, this work could lead to more personalized and effective pain management strategies for people with knee arthritis, reducing trial-and-error in finding the right medication.

How similar studies have performed: While the medications used are established, this project's approach of identifying individual biomarkers to predict specific treatment responses is a novel strategy for personalizing pain care.
