In a patient with an acute musculoskeletal injury, which modality is typically avoided?

• A. Cryotherapy
• B. Heat therapy
• C. Electrical stimulation
• D. Ultrasound

Answer: (B)

In acute musculoskeletal injuries, the priority is to limit inflammation and swelling. Heat therapy raises tissue temperature, causes vasodilation, increases blood flow and metabolic activity, and can worsen edema and inflammation. That is why heat is typically avoided in the acute phase. Cryotherapy is preferred to reduce swelling and provide analgesia, while electrical stimulation can aid pain control and early muscle activation. Ultrasound may be used in the acute stage with non-thermal (pulsed) effects to support healing, but thermal ultrasound is generally avoided.
