Abstract
In an attempt to decrease the rates of drooling of 12 children with cerebral palsy, the authors investigated the effectiveness of EMG auditory feedback training of the orbicularis oris, of making the act of swallowing a conscious one, and of providing an auditory signal to cue swallowing by means of an Accularm interval timer. After biofeedback training there was a significant decrease in drooling rates and a small increase in swallowing rates. After the Accularm was used the children maintained the decreased drooling rates and there was a further small improvement in swallowing rates. One month after treatment stopped there was a non-significant regression in the rates of both drooling and swallowing. The marked decrease in drooling after biofeedback training must be attributed to more effective swallowing as a result of improved oral motor control, rather than to increased rates of swallowing.
