The administration of heat through hyperthermia is widely used in traumatology. The main effect is tissue vasodilation in response to heating,
, which leads to the removal of inflammatory infiltrates, edema and exudates, and promotes repair. Hyperthermia increases cellular metabolism, raises the pain threshold, reduces muscle spasms, and decreases joint and fibrous tissue rigidity.
Hyperthermia can be used for post-injury stiffness and pain, chronic and degenerative joint diseases, bursitis, canalicular syndromes, myalgia and fibromyalgia, spinal pain, lumbalgia and sciatica, slow-healing tissue inflammation, chronic edema and hematomas, chronic peritendinitis, and tendinosis.
