Therapeutic ultrasound used in physiotherapy emits a sound wave to promote healing by increasing local blood flow, improving tissue relaxation and encouraging scar tissue breakdown. Therapeutic ultrasound does not take a picture but the sound waves penetrating the tissue heats the area and helps to increase blood flow. An increase in local blood flow, will help reduce local swelling and chronic inflammation.
The sound head is moved by the physiotherapist over an area for at least 5 – 7 minutes. The physiotherapist uses a gel on the skin to enhance the contact and sound wave transmission into the skin. The area (ankle, knee, hand, shoulder) should be exercised immediately after the treatment for best results.
Ultrasound is only part of the treatment session and exercises should be provided to ensure the treatment gains are maintained. Your physiotherapist will guide your treatment dosage and exercise prescription.
