Physical therapists are experts in movement and function. A large part of a physical therapist's program is directed at preventing injury, loss of movement and surgery. Physical therapists work as consultants in industrial settings to improve the design of the workplace and reduce the risk of workers overusing certain muscles or developing low back pain. They also provide services to athletes at all levels to screen for potential problems and institute preventive exercise programs.
The basics of physical therapy treatment are therapeutic exercise and functional training. In addition to "hands-on" care, physical therapists also educate patients to take care of themselves and to perform certain exercises on their own. Depending on the particular needs of a patient, physical therapists may also "mobilize" a joint (that is, perform certain types of movements at the end of your range of motion) or massage a muscle to promote proper movement and function. Physical therapists also use methods such as ultrasound (which uses high frequency waves to produce heat), hot packs and ice.
Physical therapy can only be provided by qualified physical therapists or by physical therapist assistants, who must complete an intensive education program and work only under the direction and supervision of physical therapists.
The ability to maintain an upright posture and to move your arms and legs to perform all sorts of tasks and activities is an important component of your health. Most of us can learn to live with the various medical conditions that we may develop, but only if we are able to continue at our jobs, take care of our families, and enjoy important occasions with family and friends. All of these activities require the ability to move without difficulty or pain.
