Physical therapists, sometimes referred to as PTs, help people who have injuries or illnesses improve their movement and manage their pain. They are often an important part of rehabilitation and treatment of patients with chronic conditions or injuries. Physical therapists provide care to people of all ages who have functional problems resulting from back and neck injuries; sprains, strains, and fractures; arthritis; amputations; stroke; birth conditions, such as cerebral palsy; injuries related to work and sports; and other conditions.Physical therapy programs usually award a Doctor of Physical Therapy (DPT) degree, although a small number award a Master of Physical Therapy (MPT) degree. Doctoral programs typically last 3 years; MPT programs require 2 to 3 years of study. Most programs, either DPT or MPT, require a bachelor’s degree for admission, and many require specific prerequisites, such as anatomy, physiology, biology, and chemistry.
