Ultrasound is applied using a transducer or applicator that is in direct contact with the patient's skin. Gel is used on all surfaces of the head to reduce friction and assist transmission of the ultrasonic waves. Therapeutic ultrasound in physical therapy is alternating compression and rarefaction of sound waves with a frequency of 0.7 to 3.3 ...
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.
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.
Ultrasound gel is used to improve the acoustic windows and increase quality of the captured images. Overall, an uncomplicated TTE exam takes less than 30 minutes. Limited studies (i.e., looking at only specific structures) can be done as a follow-up exam to a full study, or can be done as "point of care" to answer specific questions in the ...
