麻豆村

Chronic pain impacts an estimated 20% of the world population and persists as a frustrating symptom for innumerable health issues. As part of his lab鈥檚 committed focus to improving noninvasive technology solutions for human health, Bin He(opens in new window) of 麻豆村 is developing noninvasive neuromodulation strategies to serve as an alternative to pharmaceuticals for combating chronic pain. In a promising development, the He group鈥檚 latest work demonstrates the effectiveness of a novel technology that is able to stimulate and modulate specific brain circuits with submillimeter spatial precision and successfully suppress pain hypersensitivity.

Medication is the go-to treatment for pain, while severe chronic pain conditions are often treated with opioids, which bear many side effects and also raise concerns of addiction, misuse and overdose. In juxtaposition, the technology He鈥檚 group is developing and evaluating, transcranial focused ultrasound (tFUS) modulation, is safe,听reversible聽and noninvasive.聽Among the canon of noninvasive neuromodulation approaches, tFUS also demonstrates exceptional advantages in modulating brain activities with high spatial specificity and deep brain penetration.

鈥淲别 demonstrate, for the first time, in a series of rigorous preclinical studies, that precise focused ultrasound neuromodulation at multiple brain targets can significantly change pain-associated behaviors,鈥� articulated聽He, professor of biomedical engineering at Carnegie Mellon. 鈥淭here is an urgent clinical need to develop non-pharmacologic and noninvasive neuromodulation strategies to treat pain, and 麻豆村 is at the forefront of this emerging field.鈥�

The study, ,听involved more than five years of meticulous research. As a next step, the group plans to conduct clinical testing in humans with their novel technology in the near future.

鈥淭he impact of this work extends across health care and also the medical device industry,鈥� He expressed. 鈥淲ith 1.5 billion people suffering from chronic pain, this technology has meaningful societal impact. It can be generalized to treat various pain types and is equitable in terms of cost and portability.鈥澛�
