Physical therapists, or PTs, according to the Bureau of Labor Statistics, help injured clients with mobility and pain management. Individuals in need of rehabilitation or those who suffer from chronic conditions rely on PTs to improve their range of motion, strengthen injured muscles, and correct alignment issues. Physical therapists should have a thorough knowledge of a patient's medical history and should be in frequent communication with the patient’s primary care physician. It is also their job to track patient progress, modify treatment plans, and educate the patient’s family on stretches and other aftercare.
