Focused Ultrasound for Chronic Pain.

Chronic pain affects millions of Americans and is one of the leading reasons for individuals to seek medical attention. Focused ultrasound has been studied as a noninvasive treatment option for various pain disorders. Current studies have used focused ultrasound for ablation, neuromodulation, and opening of the blood-brain barrier for drug and therapy delivery. Most of the work has been performed in ablative studies and has shown efficacy in treating chronic neuropathic pain. Further research is needed to expand its usage in neurosurgery.
