Abstract: A method for determining muscle strength of elements of the musculature used in speech and swallowing. In particular, a tool is equipped with at least one pressure sensor. A person inserts the tool into the person's mouth and utters sounds of speech or swallows. While uttering sounds of speech or swallowing, portions of the oral musculature contact and exert force on the sensor. A representation of this force is displayed at a visual display device as an indication of muscle strength and position.

Abstract: A complemental series of handheld, tactile devices in kit form to assist in behavioral modification training techniques as well as utilizing the techiques of "resisted movement" and "successive approximation". Each positioner device is handheld, with one portion protruding from the lips and the other portion loosely fitting on the patient's hard plate. Different shapes are introduced to the tongue and lips on each respective device. A commonalty within the interdependent positioner devices is presented by an elongated palatal base defining a convex upper surface to engage the palate, a manipulable handle projecting from the base and the respective devices are further characterized in configuration.
