What are some indications for using heat therapy in rehabilitation?

Heat therapy is primarily utilized for its ability to promote relaxation and increase blood flow to specific areas of the body, making it particularly effective for conditions characterized by muscle spasms and chronic pain. The application of heat can help to soothe tight muscles, reduce stiffness, and enhance tissue elasticity, which is beneficial in the management of chronic pain conditions such as arthritis or lower back pain.

In contrast, the use of heat therapy is generally not advisable for acute injuries and sprains, as it could exacerbate swelling and inflammation. Bone fractures require specific interventions that are more suited to stabilization and healing rather than thermal applications. Post-surgical recovery may involve heat, but this is not as broadly applicable as in cases of muscle spasms and chronic pain, since the type and stage of the surgery play a significant role in determining the appropriateness of heat application.
