Physiological Studies in Healthy Subjects, Chronic Pain Patients and in Patients Undergoing Neurosurgical Procedures of Human Forebrain Mechanisms Mediating Somatic Sensation, Motor Control and Neurological Disorders
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The conditioned expectation of pain is an important aspect of pain-related disability produced by environments and stimuli associated with a painful injury on the job, although the neuroscience of this expectation is unclear. We will develop and use novel objective methods for measurement of expectation and threat related attention. The results of this study may lead to testable hypotheses regarding the psychological basis of the fear of pain, threat and task related attention. We will also use these results, and development of novel autonomic and ratings metrics for state and trait anxiety as well as threat and task related attention which could be used as an instrumented test for diagnosis and management of PTSD and anxiety disorders. .
