Ultrasound therapy can be effective in treating various conditions, including:
Carpal tunnel syndrome
Sprains and strains
Ultrasound therapy can speed up the healing process by generating heat to increase blood flow and deliver more oxygen and nutrients to the affected area. Ultrasound has been used to reduce swelling and edema, leading to decreased pain, and it also has been used to soften scar tissue and adhesions through the gentle massage of muscle tendons and ligaments.
How Does Ultrasound Therapy Work?
The device is usually applied directly to the patient’s skin with a round-tipped wand or transducer head, which resembles a microphone. Ultrasound gel is used on the skin to decrease friction and act as a conductor.
Ultrasonic waves are generated by the vibration of crystals inside the head of the wand or probe. These sound waves are pulsed at the affected area millions of times per second, causing vibration of the surrounding tissues, which in turn produces heat that is absorbed by connective tissues, ligaments, tendons, fascia, and also by scar tissue.
This type of therapy provides a non-invasive, targeted pain relief without the use of medications or surgery.
The vibration caused by the waves may produce deep heating locally, although patients might feel only a slight sensation of warmth during ultrasound therapy. The treatment usually takes from three to five minutes or sometimes longer, depending on the size of the area receiving treatment. Ultrasound therapy should never hurt or cause discomfort for the patient, and the full effects of treatment are typically felt within 24 hours.
