High & Low Pain State
A normal brain looks different than a brain in pain as seen using the PainQx System
Patient Case Study:
Patient with chronic neuropathic pain caused by nerve compression in the spine.
Top Panel: Patient Before Surgical Decompression
Over-activated brain regions relative to norms correlated with Pain Matrix. Patient reported pain score: [4 out of 10]
Bottom Panel: Patient After Surgical Decompression
Low-activated brain regions relative to norms correlated with Pain Matrix. After surgery, patient reported pain score: [0 out of 10]
