Also known as the treatment domain. Within this domain athletic trainers function similar to a physical therapist. They will provide patients with individualized treatment plans, oversee treatment plans provided by physical therapists, use modalities such as ice, heat, ultrasound, and electrical stimulation. Athletic trainers will also work with athletes and patients on graduated treatment plans to make sure they are ready to return safely to their sport or other activities they enjoy doing. This includes overseeing concussion return to play protocols when needed.
