What is a common application of ultrasound therapy?

Ultrasound therapy is widely recognized for its ability to penetrate superficial tissues and provide therapeutic effects on deeper structures, such as muscles, tendons, and ligaments. The ultrasonic waves generated during the therapy can create deep heating effects, which can improve tissue elasticity, promote healing, and reduce pain in deeper tissues that are often difficult to reach with other forms of treatment.

In addition to the primary function described, ultrasound therapy can also help with applications such as tissue regeneration and reducing inflammation. This deep penetration is crucial because it allows physical therapists to target conditions that involve deeper structures beneath the skin without directly affecting the superficial skin layers.

Other options, while they may relate to various physical therapy practices, do not fully capture the primary role of ultrasound therapy as effectively as the correct choice. For example, while ultrasound does not directly stimulate muscle contractions like electrical stimulation would, it primarily focuses on therapeutic effects achieved through deep tissue penetration.
