Official title
Exploring Pain Modulation Mechanisms: A Study of TMS and Repeated Conditioned Pain Modulation
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Conditioned pain modulation (CPM) is the behavioral measure of diffuse noxious inhibitory control (DNIC), an endogenous pain inhibitory pathway in which pain inhibits pain. CPM is less efficient in individuals with chronic pain conditions, and it is a predictor for the development of chronic pain. Continuous stimulation of central/cortical mechanisms through engaging CPM might alter pain processing and improve pain inhibition. Transcranial Magnetic Stimulation (TMS) is a valuable tool for assessing how effectively the brain's central and cortical mechanisms engage in pain inhibition, particularly through pathways like CPM. While alterations in cortical excitability related to analgesic-induced pain inhibition have been documented, the effects of continuous stimulation of central pain pathways, along with the mediating influence of psychosocial factors, remain underexplored. This study aims to investigate the central pain modulatory mechanisms, as assessed by CPM, and cortical excitability, as measured by TMS, in healthy participants. Additionally, the study will evaluate the impact of sociocultural factors, including ethnic identity, optimism, resilience, perceived stress, and marginalization, on the magnitude and efficiency of CPM responses. The successful completion of this research will determine how cortical excitability changes due to training and whether these changes are mediated by psychosocial factors.
