Physical therapy is an exercise program that helps you to improve movement, relieve pain, encourage blood flow for faster healing, and restore your physical function and fitness level. The main aim of physical therapy is to make your daily activities such as walking, getting in and out of bed, or climbing stairs easier. It can be prescribed as an individual treatment program or combined with other treatments.
Physical therapy may be ordered to help you recover after certain surgeries, injuries and long-term health problems such as arthritis. It involves a combination of education, manual therapy, exercises, and techniques such as water, heat, cold, electrical stimulation, and ultrasound.
For knee problems, therapy involves strengthening and stretching certain joints and muscles. Physical therapy for the knee is designed to improve muscle strength of the knee and reduce pain.
A physical therapist demonstrates the exercises and answers any questions about the therapy. It is important to strictly follow the program they recommend.
