Quantitative Sensory Testing in Response to Music Interventions

简要总结

详细描述

Chronic pain is devastating to individuals and society. Individuals who experience chronic pain have poorer health outcomes, utilize increased healthcare resources and have higher rates of disability. At present, treatment of chronic pain is limited to behavioral interventions and pharmacologic interventions. Many individuals with chronic pain will use opioid analgesics at some point in the continuum of pain. Prolonged use of opioid analgesics--even for durations as short as 3 days puts individuals at risk for nonmedical opioid use, addiction, and may fuel transitions from oral opioids to heroin. Outside of the original insult precipitating chronic pain, increasing evidence suggests that individual factors such as anxiety and catastrophizing are associated with development of chronic pain and increased painful response to stimuli. It is therefore suggestive that treating underlying causes of anxiety and catastrophizing may lead to novel adjunctive therapies to manage chronic pain. Music is emotive and known to modulate affect. Music that "feels good" has been described to modulate the dopaminergic and serotonin reward pathways in the brain thereby improving positive affect. Improved affect counteracts negatively valenced affect like depression, anxiety, and catastrophizing, and may be able to modulate the individual response to pain. The purpose of this pilot study is to investigate the acceptability and feasibility of a smartphone-based app on healthy volunteers. In order to measure the impact of the music app on individual responses to pain, the investigators will use quantitative sensory testing (QST) to induce a mild-moderate, standardized pain stimulus, and measure participants' pain in the absence and presence of this music intervention. The QST is a 10 minute session that includes a set of sensory tests, which elicit a mild to moderate painful response, including a pressure pain threshold and tolerance using a handheld digital algometer, the temporal summation of pain using a set of weighted pinprick probes, and immersing hand in cold water. Primary outcome will be the modulation of pain scores by music, and secondary outcomes will include the impact of music on anxiety and catastrophizing, using brief, validated questionnaires, and whether changes in these measures of affect mediate any impact on pain processing.
