ULTRASOUND THERAPY Submitted by Bianca Coetzee
The first large-scale application of ultrasound was for SONAR during World War II. Submarines sent out short pulses of ultrasound through the water which would bounce back from an object determining how far away it was. Since then it has been used in medical imaging of babies and other internal structures. For the past 50 years it has been used in the clinical setting for treating various soft tissue and joint conditions.
WHAT IS ULTRASOUND
Ultrasound is a type of sound with a frequency of more than 20 000 cycles per second. It has similar characteristics to audible sound but the human ear can’t hear it. This is why it is named ultrasound.
- Tendon and soft tissue injuries
- Resorption of calcium deposits
- Pregnancy (Treatment around the uterus)
- Pacemaker (Treating around the chest and upper back)
- Exposure to the eyes and reproductive organs
- Plastic components
- Close to breast implants
- Acute inflammation
WHAT TO EXPECT DURING TREATMENT
Ultrasound therapy is painless with most people feeling no physical sensation during treatments. A moderate amount of gel will be applied to the desired area and the head of the machine will be moved in a slow circular motion around the structures. Treatment lasts about 5 minutes depending on the size of the area being treated.
