Ultrasound is high-pitched sound that people cannot hear. These
high-pitched sound waves are sometimes used to treat muscle spasms and pain and
to promote healing.
Ultrasound at higher intensities creates a deep heat. This heat may help
to ease muscle spasms, relax and warm muscles, and increase muscle elasticity
before stretching and exercise.
Ultrasound may also act on the cells to promote healing. At lower
intensities, ultrasound can have this healing effect without also heating the
Excessive use of either the heating or non-heating properties of
ultrasound can damage tissues. Ultrasound is not typically used for children.
