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.
This method of medical ultrasound therapy can be used for various types of pain relief and physical therapy. In physics, the term "ultrasound" [1] applies to all acoustic energy with a frequency above the audible range of human hearing. The audible range of sound is 20 hertz – 20 kilohertz. Ultrasound frequency is greater than 20 kilohertz.
In particular literature, HIFU refers to the high levels of energy required to destroy tissue through ablation or cavitation, although it is also sometimes used to describe lower intensity applications such as occupational therapy and physical therapy. Either way, HIFU is used to non-invasively heat tissue deep in the body without the need for ...
Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and accelerating chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles. [2]
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.
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.
Strength training has many benefits for health and longevity. Now many older Angelenos are seeking out a method called slow motion strength training to protect their joints and heal injuries.
ESWT is used in physical therapy for pain reduction, increase in metabolism at the cellular level, revascularisation, and recovering normal muscle tone following various disorders. [30] The use of ESWT was demonstrated in patients with frozen shoulders compared to therapeutic ultrasound with exercises. [31]
