Focused Ultrasound Neuromodulation to Peripheral Nerve System.

Area of Science:

• Neurology
• Biomedical Engineering
• Medical Physics

Background:

• Noninvasive focused ultrasound (FUS) is an emerging therapeutic technology.
• FUS offers deep penetration and precise targeting for neuromodulation.
• Applications extend to both the central nervous system (CNS) and peripheral nervous system (PNS).

Purpose of the Study:

• To summarize the principles and mechanisms of FUS neuromodulation on the PNS.
• To review current experimental findings on PNS targets treated with FUS.
• To discuss the limitations and future perspectives of FUS in neurotherapeutics.

Main Methods:

• Review of existing literature on FUS principles and mechanisms.
• Analysis of experimental studies investigating FUS for PNS neuromodulation.
• Discussion of comparative performance against established neurotherapeutic devices.

Main Results:

• FUS demonstrates effective neuromodulation for various PNS targets.
• Experimental results indicate satisfactory performance, comparable to FDA-approved devices like vagus nerve stimulation (VNS).
• FUS shows potential as a noninvasive, safe, and effective neurotherapeutic modality.

Conclusions:

• FUS is a promising noninvasive tool for neurotherapeutics in both CNS and PNS.
• While research on PNS applications is less extensive than CNS, current findings are encouraging.
• FUS is expected to see wider clinical applications and technological advancements soon.
