Years",{"count":64,"type":22},95,"OBSERVATIONAL","This study addresses the timely problem of painful temporomandibular disorders (TMD), the most common cause of orofacial pain second only to tooth pain. Findings from previous studies suggest that dysregulation of connectivity within specific brain circuits is part of chronic pain pathophysiology. This study will identify connectivity patterns within those brain circuits as potential signatures for pain- related disability in chronic TMD pain participants. New knowledge regarding these brain connectivity patterns is expected to be significant because it will support improved phenotyping of this heterogeneous participant population. It is also expected that this finding can potentially be extrapolated to other chronic pain conditions, such as back pain, migraine headache, and fibromyalgia that are frequently comorbid conditions in chronic TMD participants.",[68,28,30],"Chronic Pain","RECRUITING","2025-09-04",{"date":72,"type":46},"2025-09-08",{"date":74,"type":46},"2022-03-02",{"date":76,"type":22},"2026-08-31",{"name":78,"class":79},"University of Minnesota","OTHER",1]
