Ultrasound also known as sonography uses sound waves to build ultrasound images of things that are going on inside a human. A tool known as transducer helps in the emission of high-frequency sound, not audible to human ears to record the sound waves echoing and bouncing back in order to determine the shape, size and consistency of organs and soft tissues.

The therapeutic effects of ultrasound are disputed. Today, there is not much evidence explaining how ultrasound helps in creating therapeutic effects in injured tissues. However, people still continue to use the ultrasound treatment depending on their personal experience instead of a scientific evidence.
