For a client with a contusion, what is the primary goal of applying heat?

The primary goal of applying heat to a contusion is to speed up the rate of absorption of blood that has accumulated in the tissue. When a contusion occurs, there is usually bleeding beneath the skin due to damaged blood vessels. Applying heat helps to promote vasodilation, which increases blood flow to the affected area. This enhanced circulation can facilitate the reabsorption of the extravasated blood, therefore aiding in faster healing.

While alleviating pain, preventing swelling, and increasing mobility may also be important aspects of the management of a contusion, they are not the main goal of applying heat specifically. Pain relief might occur as a secondary effect, and swelling is typically managed in the acute phase with cold therapy initially, rather than heat. Mobility is a longer-term goal that is addressed once acute management of the injury has been effectively dealt with.
