Professor Nephew and Professor King are currently focusing on using fNIRS technology to study chronic pain in hopes of identifying biomarkers or aspects of brain activity that predict levels of chronic pain. By using the fNIRS technology, the team is able to measure levels of oxygenated and deoxygenated blood which indirectly correlates with a change in brain activity. Putting those with and without chronic pain through a series of cognitive and physical tests, they are hoping to discover certain indicators or predictors of chronic pain as well measure the effectiveness of a variety of treatments for chronic pain.
