Pain Paid Clinical Trials in North Carolina

Recent literature has shown that individuals with persistent chronic pain often exhibit altered cognitive, affective, and sensorimotor behaviors despite a full recovery of peripheral structural injury. Clinically this can be observed via altered pain behaviors (e.g., pain catastrophizing and kinesiophobia) and increased sensitivity to pressure stimuli, each of which are predictive of poorer outcomes. These alterations are believed to have arisen from maladaptive reorganization of brain networks, including cognitive-evaluative and affective networks. Structurally, decreased gray matter in the dorsolateral prefrontal cortex (DLFPC), a key area in the cognitive-affective processing of pain, has been found in those suffering from chronic musculoskeletal pain. The changes are shown to be reversible when the pain is successfully treated and uniquely connected to cognitive-affective behaviors in that as catastrophizing or fear decreases, DLPFC density increases. Pain science education (PNE), a cognitive-behavioral intervention, has shown promising effects, especially on cognitive- affective behaviors. Non-invasive brain stimulation, such as transcranial direct current stimulation (tDCS), has also been shown to reduce pain and pain-associated behavioral changes in chronic pain. However, the combined effects of these two interventions have not been investigated. It remains unclear if priming the cognitive-affective circuitry that is conceptualized to support PNE with tDCS will augment the behavioral effect of PNE. Therefore, the primary objective of this pilot study is to examine the effects of combining PNE and tDCS on pain catastrophizing, kinesiophobia, and hypersensitivity to pressure stimuli in patients with chronic low back pain (CLBP). We will also examine the influence of PNE and tDCS on cortical network patterns in a subgroup of participants. The results of this pilot study could support the use of tDCS as a priming agent to increase the effect of cognitive-behavioral interventions such as PNE. With success, this intervention could be safely and easily replicated in the clinical setting and provide a novel approach to treating chronic pain more effectively. In addition, the outcomes can further the understanding of more precisely matching specific cortical targets with the desired behavioral therapy Read Less

The UPGRADE registry will capture long-term, real-world outcomes to understand the effect of Differential Target Multiplexed (DTM®) programming in the Spinal Cord Stimulation (SCS) implanted population on the management of chronic pain, primarily on its use for trunk and/or limb pain. The clinical study is sponsored by Celéri Health and is funded through a financial grant from Medtronic's External Research Program. The registry study will be conducted across approximately 25 centers in the United States with up to 600 participants enrolled. Read Less
