Home ultrasound is the provision of therapeutic ultrasound via the use of a portable or home ultrasound machine. This method of medical ultrasound therapy can be used for various types of pain relief and physical therapy.
In physics, the term "ultrasound" 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.

Home ultrasound machines
Ultrasound energy is transferred based on the frequency and power output of the ultrasonic waves that an ultrasound machine or device creates. Home ultrasound machines and doctor's office machines both operate between 1 and 5 megahertz, however, home machines utilize pulsed ultrasonic waves while professional ultrasound machines in a doctor's office use continuous waves.
Typically, when using a home ultrasound machine, you will use it more frequently than if you were to have ultrasound treatments at a therapist's office, but the end results are the same as if using a continuous wave machine less frequently.
Home ultrasound benefits
Home ultrasound machines may have several benefits: long-term cost savings, portable physical therapy treatment, long-term pain relief for multiple symptoms, possible decrease in healing time, and can reduce chronic inflammation.
Different types of ultrasound therapy
Home ultrasound machines operate within the range of frequencies of therapeutic ultrasound, as opposed to the more commonly known diagnostic ultrasound, or Diagnostic sonography. Typical diagnostic ultrasound machines operate in the frequency range of 2-18 megahertz, whereas home ultrasound machines and therapeutic ultrasound machines operate in the frequency range of .7-3.3 megahertz. Diagnostic sonography is typically used to create an audio "image", such as during pregnancy to visualize the developing baby.
Home ultrasound and phonophoresis
Phonophoresis, also known as sonophoresis, is the use of ultrasound to enhance the delivery of topically applied drugs. Home ultrasound allows the application of topically applied analgesics and anti-inflammatory agents through the therapeutic application of ultrasound. It is widely used in hospitals to deliver drugs through the skin. Pharmacists compound the drugs by mixing them with a coupling agent (gel, cream, ointment) that transfers ultrasonic energy from the ultrasound transducer to the skin. The ultrasound potentially enhances drug transport by cavitation, microstreaming, and heating.
