Davis Company PP New York, NY SN 9781719641999 LK fadavispt.mhmedical.com/content.aspx?aid=1187660049 RD 2024/03/28 AB Thermal agents are used in physical therapy and rehabilitation to reduce pain, to enhance healing, and to improve motion. The physical therapist should have a solid foundation in the normal physiologic control of the cardiovascular and neuromuscular systems prior to using an agent that can alter the function of these structures. In addition, a background in the physiology of healing mechanisms and of pain serves as a basis for the rationale of using thermal agents.
