Athletic training as defined by the NE DHHS means the prevention, evaluation, emergency care, first aid, treatment and rehabilitation of athletic injuries by the use of electrical stimulation, ultrasound, medical diathermies, infrared light, and ultraviolet light under guidelines established with a referring licensed physician.  Athletic injuries mean the types of musculoskeletal injury or common illness and conditions which athletic trainers are educated to treat or refer, incurred by athletes, which prevent or limit participation in sports or recreation.  Persons who solely use heat, cold, air, water or exercise are not considered to be practicing athletic training.
