Automatic cueing to reduce drooling: a long-term follow-up with two mentally handicapped persons.

A follow-up was carried out on two mentally handicapped persons to check whether automatic cueing remained effective for reducing their drooling. The follow-up data were collected through observation sessions which were spread over a period of 18 months. These sessions together with the posttraining sessions of the original study covered an interval of about 2 years. The results of the follow-up showed that cueing continued to be fairly effective with drooling remaining at relatively low levels.
