Methods We Use

In each of our studies, use a variety of different methods to collect useful data from individuals with chronic pain and pain-free controls. By comparing data across these different methods, we are able to answer more complex questions about chronic pain and related symptoms.

Functional Magnetic Resonance Imaging (fMRI) By collecting MRI (anatomical) and fMRI (activity) data from the brain and spinal cord, we are able to view how the nervous system is altered by chronic pain. While in the MRI scanner, our participants are asked to relax, complete tasks on a screen, or simply relax. Transcranial Magnetic Stimulation Transcranial Magnetic Stimulation (TMS) offers a way to change brain activity via a magnetic wand like device held next to the scalp. TMS treatment feels like a tapping sensation on the scalp. TMS is able to slightly increase or decrease brain activity in certain regions of the brain by creating small electric pulses within the brain (all non-invasively). Quantitative Sensory Testing Quantitative sensory testing (QST) is a way to measure an individual’s perception of pain and sensory stimulation. We use a variety of different QST devices to measure your responses to pressure, heat, and cool stimuli. Clinical & Behavioral Questionnaires Secure surveys are a great way to understand each individual’s perspective based on their life experiences, current feelings, and clinical symptoms. All of these de-identified perspectives are very important factors in how chronic pain is experienced by each individual person, so these survey data greatly help us understand and interpret our study results.
