Ultrasound: what is it?
Ultrasound may be prescribed by your physician and administered by a physical therapist to help relax tight muscles that are painful. It is used to warm muscles and soft tissue to increase blood flow that will help healing. It may be used as part of your main physical therapy treatment. Ultrasound is high-frequency sound waves that are transferred to a specific body area using a 1-2" wand. Your P.T. applies a gel to your skin which makes a smooth, gliding surface, then slowly moves the wand over the affected area. It is not painful; you may feel some warmth.
