Ultrasound Therapy

What is ultrasound therapy?
Ultrasound therapy is a physical therapy that aims to provide deep tissue heating to soft tissues such as muscles, tendons and ligaments in the body. By using deep heat on these structures, it increases the flexibility of tissue that may be tight and also improves the circulation to area to aid in healing. Ultrasound can also be used without deep heat and this is known as cavitation. Ultrasound allows energy to enter into the affected area and this energy causes microscopic bubbles to increase and decrease around
the tissue. This process improves cellular mechanisms and tissue repair.

What is ultrasound therapy used for?
• Sprains and ligament injuries
• Muscle strains and tears
• Tendonitis
• Bursitis
• Stress fractures
• Osteoarthritis
• Chronic muscle pain
• Bursitis
• Plantar Fasciitis
• Achilles Tendinopathy

How does ultrasound work?
Ultrasound works on sound waves. It is generated by applying an alternate current to a piezoelectric crystal (found in the transducer in the sound head). This crystal contracts and expands at the same frequency at which current changes polarity. The sound field generated by this crystal in turn makes the molecules in the sound field vibrate and oscillate. If one molecule is set in vibration, then it will cause its immediate neighbors to vibrate, and in turn their neighbors, and so on until the vibration has propagated throughout the entire material. This is a wave. Ultrasound works at different depths and different intensities, this will be set by the podiatrist.
