In addition to locomotor system’s deficits many children with neurological disorders and mental retardation such as cerebral palsy and Down Syndrome suffer from chronic drooling which can be seen in 10% to 38% of people with cerebral palsy and in certain patients with Down Syndrome (1,2). Drooling leads to many problems which can affect the patient’s health and parent’s social life as well as it keeps the patient away from training and rehabilitation programs. Some procedures such as behavior modification, biofeedback, oral motor therapy, speech therapy, drug therapy, radiotherapy, oro-facial regulation therapy, and surgery have been suggested to treat drooling. This review deals with the possible methods of evaluation and treatment of drooling in disabled children.
