Physical therapists come to the rescue after a stress fracture sidelines a runner, when an awkward slide into home plate benches a softball player or after a stroke keeps a person bedridden. Patients with health issues ranging from athletic injuries to neurological traumas are often referred to these professionals by their doctors.

Physical therapists evaluate a patient and examine their medical records. Then, they plan and execute rehabilitation programs designed to improve the patient’s mobility, increase their strength and relieve – or at least lessen – their pain. Treatment plans often include different exercises and stretches, as well as hands-on therapy and machines that assist with improving muscle strength, range of motion and motor function.

Physical therapists must earn a doctor of physical therapy, or DPT, degree. There are more than 200 accredited physical therapy programs, according to the Commission on Accreditation in Physical Therapy Education.

Here’s how to start your career as a physical therapist:

1. Earn a bachelor’s degree. Prerequisites are needed for entrance to a physical therapy program. Courses required may include anatomy, biology and chemistry.
2. Enroll in a doctor of physical therapy program. DPT programs are typically three years long, and usually require proof of a bachelor’s degree before admittance. These programs typically include courses in pharmacology, biomechanics and neuroscience, according to the BLS.
3. Complete a clinical residency. After graduating, physical therapists might choose to complete a clinical residency or fellowship to gain more practical experience.
4. Obtain your license. Physical therapists need to pass the National Physical Therapy Examination, and may need to meet state-specific requirements as well.
5. Become board-certified. Therapists looking to specialize can choose to obtain additional certifications. These specialists are required to pass an exam and complete several hours of clinical work before receiving certification.

Physical therapists are also expected to complete continuing education throughout their career to stay on top of the latest techniques and maintain their licensure.
