Which is an indication for thermal ultrasound among the following?

• A. Subacute or chronic inflammation of tendon
• B. Acute ligament sprain
• C. Acute bone fracture
• D. Acute inflammatory joint effusion

Answer: (A)

Heating ultrasound raises tissue temperature to boost blood flow, facilitate tissue remodeling, and increase collagen extensibility. In the subacute or chronic phase of tendon inflammation, these heating effects help the healing process and reduce stiffness and pain, making thermal ultrasound an appropriate choice. In contrast, acute conditions such as an acute ligament sprain, an acute bone fracture, or an acute inflammatory joint effusion involve active inflammation and edema, where heat can worsen swelling and inflammation. Cold therapy or non-thermal ultrasound is typically preferred in those cases.
