简要总结
The objective is to identify modifiable clinical factors and neurobiological pathways that lead to the development of chronic pain in patients with early rheumatoid arthritis. Participants will undergo quantitative sensory testing, a type of testing that involves assessing response to well-defined, quantifiable painful stimuli, at 0, 3, and 12 months. A subset of participants will also undergo magnetic resonance imaging at 0 and 12 months to assess neuroimaging markers that have previously been shown to be involved in chronic pain.
