APPLICATOR MOVEMENT OF ULTRASOUND
If movement of the applicator is too slow, the patient may feel
periosteal pain characterized by a deep ache or pain. If motion is
too fast, or if the applicator does not maintain good contact with
the skin, the therapeutic effect of the sound waves will be reduced
and the applicator may overheat.
POTENTIAL ADVERSE EFFECTS OF ULTRASOUND
• Cataracts
• Male Sterility
• Enhanced Drug Activity
• Thermal Stress
PATIENT SUSCEPTIBILITY
Some patients are more sensitive to ultrasound output and may
experience a reaction similar to a heat rash. Be sure to inspect the
treatment area during and following treatment, and discontinue if
an adverse reaction does occur.
COUPLING
Coupling is described as contact between the applicator and
the treatment site and may be accomplished through the use of
a coupling agent, such as gel or lotion. Anything used as a coupling
agent must be highly conductive. Air is a very poor conductor of
ultrasonic waves.
DO NOT
use a conductive medium with an
alcohol based content or that is not approved specifically for
ultrasound conductivity.
