A meta-analysis found that ultrasound therapy is effective in reducing pain, increasing ROM, and reducing WOMAC functional scores in patients with knee osteoarthritis. [7] There are three potential therapeutic mechanisms of ultrasound in physical therapy. The first is the increase in blood flow in the treated area.
Low intensity pulsed ultrasound has been proposed as a therapy to support bone healing after fractures, [1] osteomies, or delayed healing. A 2017 review, however, found no trustworthy evidence for the use of low intensity pulsed ultrasound for bone healing, mostly based on the large pragmatic randomized controlled trial published in 2016.
The mechanism of action for sonodynamic therapy is the use of low-intensity ultrasound through the use of focused mechanical waves to create a cytotoxic effect. However, SDT itself is non-thermal, non-toxic, and is able to non-invasively penetrate deep into tissue compared to other delivery methods such as photodynamic therapy.
Ultrasonic impact treatment (UIT) uses ultrasound to enhance the mechanical and physical properties of metals. [51] It is a metallurgical processing technique in which ultrasonic energy is applied to a metal object. Ultrasonic treatment can result in controlled residual compressive stress, grain refinement and grain size reduction.
These techniques are known as Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS) [39] [40] and Ultrasound guided Focused Ultrasound Surgery (USgFUS) respectively. [ 1 ] [ 41 ] MRgFUS is a 3D imaging technique which features high soft tissue contrast and provides information about temperature, thus allowing to monitor ablation.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Scientists continue to test a variety of mammals such as humans, monkeys [5] and mice on positively affecting the treatment of epilepsy, Parkinson's disease, chronic pain, coma, dystonia, psychoses and depression by applying safe, low-intensity, TPU. Because the potential for this technology covers a wide variety of benefits, continued research ...
Ultrasound and microbubble treatment without additional drugs impeded the growth of small tumors but required a combinatorial drug treatment to affect medium-sized tumor growth. [54] With their immune stimulating mechanism, ultrasound and microbubbles offer a unique ability to prime or enhance immunotherapies for more effective cancer treatment.
