Ultrasound Treatment is a therapeutic modality that has been used by physical therapists since the six decades. Ultrasound is applied using a round-headed wand or probe that is put in direct contact with the patient's skin. Ultrasound gel is used on all surfaces of the head in order to reduce friction and assist in the transmission of the ultrasonic waves. Therapeutic ultrasound is in the frequency range of about 0.8-3.0 MHz. Ultrasound therapy has been shown to cause increases in tissue relaxation, local blood flow, and scar tissue breakdown. The effect of the increase in local blood flow can be used to help reduce local swelling and chronic inflammation, and promote bone fracture healing. The intensity or power density of the ultrasound can be adjusted depending on the desired effect. A greater power density is often used in cases where scar tissue breakdown is the goal. Ultrasound Treatment is recommended for tendonitis, non-acute joint swelling, muscle spasm. Contraindications of ultrasound include local malignancy, metal implants below the area being treated, local acute infection, vascular abnormalities, and directly on the abdomen of pregnant women. It is also contraindicated to apply ultrasound directly over active epiphyseal regions in children, over the spinal cord in the area of a laminectomy, or over the eyes, skull, or testes. A typical ultrasound treatment will take from three to five minutes. In cases where scar tissue breakdown is the goal, this treatment time can be much longer. During the treatment, the head of the ultrasound probe is kept in constant motion. If kept in constant motion, the patient should feel no discomfort at all.
