The LG “Pro Series Elite” is a portable ultrasound device that generates deep
ultrasonic waves within body tissues for the treatment of selected medical
conditions such as pain relief, muscle spasms, and joint contractures, but not
recommended for the treatment of malignancies. This is an FDA regulated
product available by prescription only. Keep out of reach of children.
INTENDED USE
The LG “Pro Series Elite” is an ultrasonic therapeutic device that generates
pulsed high frequency sound waves (1MHz) that are transferred to a specic
body area via a sound head probe. The pulsed sound waves travel deep into
the tissue to generate vasodilation, which helps increase blood ow to the
treated area.
Therapeutic ultrasound is found to help relieve pain and reduce muscle
spasms and is one of the most frequently used therapies by physicians and
physical therapists. Most patients will feel nothing at all during treatment,
while some patients may feel slight warmth.
