The Iowa Oral Performance Instrument (IOPI) objectively measures tongue and lip strength and endurance. It is also used to provide biofeedback regarding endurance and fatigue during isometric oral motor exercise programs in clients with dysphagia or dysarthria. The purpose of this study was to determine a variety of ways to use the IOPI in therapy in order to increase oral agility and swallowing in a 24-year old female client with a diagnosis of spastic-athetoid developmental dysarthria. Data was collected over a span of nine weeks at the university center for speech and hearing. Follow-up data was obtained four weeks after cessation of treatment with the IOPI. A variety of innovative protocols were designed to ensure that the IOPI will be of maximum benefit to the client. First, oral motor exercises targeting placements of the tongue bulb were performed prior to using the IOPI. Second, each measurement was taken in a specific sequence using the muscle maps of the tongue and lip in order to reduce the effects of fatigue and adaptability of the tongue and lip musculature. Third, anatomical visuals were used during treatment to allow the client to view a cross-section of the vocal tract and the placement of the bulb for each measurement obtained. The client showed improvement in swallowing behaviors following the treatment. The client also expressed her perceptions regarding the treatment protocols. Finally, the optimum bulb placement procedures in order to derive maximum benefit from IOPI treatmentwere discussed.
