What do physical therapists do?

You have probably heard of the profession of physical therapy. Maybe you have had a conversation with a friend about how physical therapy helped get rid of his or her back pain, or you might know someone who needed physical therapy after an injury. You might even have been treated by a physical therapist yourself. But have you ever wondered about physical therapists--who they are and what they do? Many people are familiar with physical therapists' work helping patients with orthopedic problems, such as low back pain or knee surgeries, to reduce pain and regain function. Others may be aware of the treatment that physical therapists provide to assist patients recovering from a stroke (e.g., assisting them with recovering use of their limbs and walking again).

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.

Because physical therapists are experts in movement and function, they do not confine their talents to treating people who are ill. A large part of a physical therapist's program is directed at preventing injury, loss of movement, and even 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. With the boom in the golf and fitness industries, a number of physical therapists are engaged in consulting with recreational golfers and fitness clubs to develop workouts that are safe and effective, especially for people who already know that they have a problem with their joints or their backs.

The cornerstones 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. Although other kinds of practitioners will offer some of these treatments as "physical therapy," it's important for you to know that physical therapy can only be provided by qualified physical therapists or by physical therapist assistants, who must complete a 2-year education program and who work only under the direction and supervision of physical therapists.

Most forms of physical therapy treatment are covered by your insurance, but the coverage will vary with each plan. Most states do not legally require patients to see their physicians before seeing a physical therapist. Most of the time all you have to do is ask your doctor if physical therapy is right for you.

Is physical therapy painful?

For many patients, one of the primary objectives is pain relief. This is frequently accomplished with hands-on techniques, modalities such as ultrasound, electrical stimulation, and/or heat or cold therapy. Movement often provides pain relief as well. Your physical therapist will provide you with the appropriate exercises not only for pain relief but to recover range of motion, strength, and endurance.

In some cases, physical therapy techniques can be painful. For example, recovering knee range of motion after total knee replacement or shoulder range of motion after shoulder surgery may be painful. Your physical therapist will utilize a variety of techniques to help maximize your treatment goals. It is important that you communicate the intensity, frequency, and duration of pain to your therapist. Without this information, it is difficult for the therapist to adjust your treatment plan.

What will I have to do after physical therapy?

Some patients will need to continue with home exercises. Some may choose to continue with a gym exercise program. Others will complete their rehabilitation and return to normal daily activities. It is important that you communicate your goals to your therapist, so he/she can develop a custom program for you.
