Ultrasonic therapies for seizures and drug-resistant epilepsy

Frontiers in Neurology, 2023
Ultrasonic therapy is an increasingly promising approach for the treatment of seizures and drug-resistant epilepsy (DRE). Therapeutic focused ultrasound (FUS) uses thermal or nonthermal energy to either ablate neural tissue or modulate neural activity through high- or low-intensity FUS (HIFU, LIFU), respectively. Both HIFU and LIFU approaches have been

ULTRASONIC THERAPY

Australian Journal of Physiotherapy, 1955
Ultrasonic or supersonic waves have a frequency outside the range at which the human ear is capable of perceiving them as sound. The frequency of audible sound lies between sixteen and twenty thousand oscillations a second. Anything outside those figures is inaudible; ultrasound consists of frequencies above twenty thousand.

Microbubbles Ultrasonic Cavitation Regulates Tumor Interstitial Fluid Pressure and Enhances Sonodynamic Therapy

Frontiers in Oncology, 2022
Sonodynamic therapy (SDT) is a promising treatment method for solid tumors. However, the high interstitial fluid pressure (IFP) in tumor tissues limits the accumulation of sonosensitizers. In the present study, microbubbles ultrasonic cavitation was used
