Physical Therapist Assistants (PTAs) provide patient treatment which is planned and supervised by a Physical Therapist. These services help improve mobility, relieve pain, and prevent or limit additional physical damage associated with many types of injury and disease. PTAs utilize skills in anatomy and physiology, body mechanics, exercise and fitness, first aid, massage, and treatment methods such as ultrasound, hydrotherapy, and electro-stimulation, as well as patient care, communications, psychology, and computer technology.

The Physical Therapist Assistant also provides a vital link in the treatment and recovery chain by tracking and recording patients' progress during treatment and communicating patient responses and changes to the Physical Therapist for streamlining the overall treatment process.
