PTAs work with licensed physical therapists to provide treatment for physical injury or disability. Treatments include application of heat, cold, ultrasound, electrical stimulation and massage, as well as training in therapeutic exercise and functional activities. WCC's PTA program is particularly successful at training PTAs both locally and across the state. The purpose of the PTA program is to graduate skilled technical health care professionals who are capable of carrying out treatment programs under the supervision of licensed physical therapists. Curriculum design is oriented to develop skills as well as comprehension of underlying theory, both of which are essential to competent practice.
