What is the primary function of therapeutic ultrasound?

The primary function of therapeutic ultrasound is to penetrate tissues for healing. This modality uses high-frequency sound waves to create thermal and non-thermal effects within the tissue. The sound waves increase the temperature of the targeted tissues, which can promote blood flow, reduce muscle tension, and enhance the healing process. The non-thermal effects can also stimulate cellular activity, aiding in tissue repair and promoting faster recovery from injuries.

In contrast, the other options focus on functions that are distinct from the purpose of therapeutic ultrasound. Diagnosing medical conditions typically involves imaging techniques such as X-rays or MRI, which are not the focus of ultrasound therapy. Delivering medication can be achieved through methods like iontophoresis or injections rather than therapeutic ultrasound. Performing surgical procedures involves invasive techniques that are separate from the non-invasive nature of therapeutic ultrasound treatments. Thus, the option of penetrating tissues for healing aligns closely with the established applications and goals of therapeutic ultrasound in the field of sports medicine.
