Physical therapists (PTs) treat patients to relieve their pain and increase their strength and mobility.

Physical therapists care for patients with injuries or illnesses. Doctors refer patients to physical therapy for conditions such as:

• Lower back pain
• Arthritis
• Broken bones
• Sport injuries
• Strokes
• Heart disease

Physical therapists help patients decrease pain and improve strength. They also try to prevent permanent disabilities or stop conditions from worsening.

Physical therapists review the doctor's referral and the patient's medical history. They test the patient's posture, balance, strength, muscle function, and range of motion. When their evaluation is complete, therapists write a treatment plan.

Physical therapists use a wide range of treatments (or modalities), such as:

• Exercise
• Hot and cold applications
• Ultrasound and electrical stimulation
• Deep tissue massage

They make sure patients understand how treatments work and answer questions. Therapists teach patients how to do exercises at home and use supportive devices such as crutches and walkers. They also teach families how to help patients with their exercises. They may refer patients for prosthetic devices, which are artificial replacements for legs or arms.

Physical therapists check patients' progress and modify plans when necessary. They consult with other medical staff about patients' responses to treatment. They keep detailed patient records. Physical therapists may supervise physical therapy aides and assistants who help to carry out treatment plans.

Some physical therapists specialize in one type of care such as sports medicine. Others help to develop fitness- and wellness-oriented programs that help to encourage a healthier and more active lifestyle.
