Clinical Trials in the Spotlight Main Page

The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) supports a range of clinical trials studying new and existing interventions for prevention and treatment of arthritis, musculoskeletal, and skin diseases.  Investigators supported by the NIAMS need your help finding individuals to participate in clinical trials.  Participating in clinical trials allows you to play an active role as a volunteer in research and contribute to generating new knowledge about the disease/condition, and potentially future treatments.  The information below is designed to help you quickly learn about actively recruiting research studies for which you or someone you know may be eligible.

Study Description

Chronic pain affects over 100 million Americans, with an annual cost estimated at over $500 billion. Reliance on opioid medications has led to an “opioid crisis” and the need to identify alternative treatment for chronic pain. This study hypothesizes that chronic pain represents failure or suboptimal function of pain modulatory capacity (PMC) and aims to test hypotheses about resilience to clinically relevant pain challenges, and test multisystem (psychological, behavioral, and neural) mechanisms underlying chronic pain. Furthermore, the study aims to demonstrate the trainability of PMC in asymptomatic controls, which has relevance for pain prevention, and in patients with fibromyalgia (FM) who are hypothesized to have suboptimal PMC (resilience) to pain challenges.

The study team will test hypotheses about the trainability of endogenous pain modulation based on similar processes seen in other physiological systems. The research is highly innovative and challenges common and unsuccessful conceptualizations of pain treatment and variability. A typical target of pain treatment is the reduction of pain variability, however, this study hypothesizes that pain variability is a marker for PMC and treatment should focus on increasing this capacity rather than eliminating it. Demonstration of the modifiability of PMC will have a direct translation to both preventions of chronic pain and treatment of chronic pain.
