What is Ultrasound?

Ultrasound is an inaudible high frequency vibration that is converted from electrical energy which passes through crystals in the transducer head. Ultrasound can be used as a diagnostic modality and for treatment purposes.

Therapeutic ultrasound is one of the most commonly used and well accepted electrotherapy modality in treating various musculoskeletal conditions.

Ultrasound therapy is usually used with the help of a coupling media. The coupling media, such as water, oil or gel prevents reflection of the ultrasonic wave away. It also allows easy movement of the transducer onto the skin, thus prevents friction and allows more evenly-spread penetration.

Some of the effects of ultrasound are:

  • Decreases soft tissue inflammation (example: tendonitis, bursitis)
  • Increases tissue extensibility
  • Enhances scar tissue remodelling
  • Decreases localised pain
  • Improves soft tissue healing
  • Reduces soft tissue swelling (edema)
  • Improves blood flow around the tissue
  • Reduces muscle spasms

Ultrasound therapy is usually set at a frequency of 1MHz or 3Mhz. 1Mhz is usually used for deeper penetration (3cm-5cm), while 3Mhz is usually set for superficial penetration (1cm-2cm). Ultrasound can be used in either continuous or pulsed mode for a duration of 5 to 8 minutes.
