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.
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.
For example, Makhmalzadeh et al. proposed an ultrasound-triggered drug delivery method involving the use of thermo-responsive hydrogels loaded with silibinin, a cancer drug for treating melanoma. [ 16 ] [ 41 ] At low temperatures, these thermo-responsive hydrogels exist in liquid form but following ultrasonication, they transition into a gel state.
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.
An analysis of a sample of joint fluid from the affected joint to check for uric acid crystals. Imaging tests like an X-rays, ultrasound, or CT scan to visualize uric acid crystals in the affected ...
Gene therapy using ultrasound and microbubbles is also being investigated for ocular disease. [25] In cardiovascular disease, for example, the efficiency of gene therapy can be improved by ultrasound targeted microbubble destruction where a gene-loaded microbubble can be burst to release its contents. [26]
In diagnosing disease of the viscera of the abdomen, ultrasound is particularly sensitive on imaging of biliary tract, urinary tract and female reproductive organs (ovary, fallopian tubes). As for example, diagnosis of gallstone by dilatation of common bile duct and stone in the common bile duct.
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.
