What is physical therapy?
We call physical therapy to all those which use physical media (radiations, heat, cold, etc.) to perform its therapeutic action. Within physical therapies we can consider different sections:
- Therapy with non-ionizing radiation (which do not exert direct damage to cells, as if it can do ionizing radiation: among others, ultraviolet rays, X-rays, gamma rays), which are mainly: infrared, microwave, and laser
- Therapy with pressure waves (ultrasonic)
- Electrotherapy
- Magnet therapy, and
