The Iowa Oral Performance Instrument (IOPI) objectively measures:
-tongue strength and endurance
-lip strength and endurance
These measures aid professionals involved in the treatment and study of disorders affecting swallowing, speech, and eating by:
-objectively documenting deficits that justify treatment
-diagnostically differentiating between muscle weakness and problems of motor control
-providing biofeedback during isometric oral motor exercise programs
-motivating patients by showing them their progress from muscle exercise therapy
