An electronic device for intermittent auditory cues

Lagopthalmos is one of the complications of Hansen´s disease. The Gillies temporalis transfer operation is the procedure of choice in the majority of cases. Postoperatively, the patient is taught chewing exercises in order to activate the upper and lower eyelids. Since this is a voluntary action, the patient needs a physiotherapist to help him learn to blink his eyes at an optimum rate. A simple portable electronic device using a single CMOS IC was designed to deliver intermittent auditory cues at a predetermined rate. This is an unambiguous substitute for the pacing provided normally by the physiotherapist.<>
