Ultrasound is the deepest and most efficient of the deep heating therapy modalities. It combines deep heat achieved through the friction created by the sound-wave micromassage. The benefit of micromassage can be gleaned without causing heat, so ultrasound can safely be used to acute injuries.

Physiological Effect: Ultrasound has many wonderful effects and uses as described below.

  1. Creates micromassage, vibrating tissue at one million cycles per second.
  2. Causes deep heat via friction from the micromassage.
  3. Can penetrate tissue form two to four centimeters deep.
  4. Treatment lasts longer than any other deep heater (up to two hours).
  5. Can be used as micromassage only without creating heat by interrupting sound output pulse.
  6. Low intensity, interrupted ultrasound can help decrease swelling (edema) and may help to relieve pain.
  7. Ultrasound causes blood vessels to open, increasing blood flow. It also helps break up muscle adhesions with micromassage.

Subjective Experience: When receiving ultrasound treatment, the following may be experienced.

  1. When the sound head is placed against the skin, it begins to slowly warm the tissue.
  2. If using interrupted pulse, no heat will be felt.
  3. The faintest sensation of “buzzing” may be noticed in the area being treated; this is the effect of micromassage.
  4. The muscles relax and the mind often wanders. Ultrasound is most often, very calming.
  5. Upon completion of ultrasound therapy, the treated area feels lose and relaxed.

Method of Application: There are six basic steps to the application of ultrasound.

  1. The skin is bared and inspected.
  2. Coupling gel is applied to allow for a maximum transfer of the sound waves.
  3. The timer is turned on.
  4. The ultrasound head is placed in contact with the skin and moved over the area to be treated.
  5. The intensity is turned up gradually to the indicated level (the sound pulse may be interrupted at this time).
  6. Movement of the sound head continues over the treatment area until complete (the timer stops).
