The oral care support tool of the sixth embodiment can measure how the myoelectric potential, lip closing force or intraoral pressure of the subject's mouth ring muscle responds to this pulling stimulus. . Repeated tensile stimulation may restore the subject's functions such as eating, swallowing, and articulation.

  Further, a tensile force is transmitted from the vestibule to the outside of the lips to the disc, and the tensile force measurement unit 607 measures the tensile force when the disc jumps out of the lips. As the tensile force measuring unit 607, a known force gauge or pull gauge can be used.

FIG. 9 is a diagram illustrating an example of time-series data of the orbital myoelectric potential, the lip contact pressure, and the intraoral pressure when the cheek movement is executed. The cheek movement is a movement that closes the lips and raises the air pressure in the mouth to inflate the cheek, or lowers the air pressure in the mouth to squeeze the cheek. It can be observed that the lip contact pressure (LipF) and the oral muscle potential (EMG) change according to the level of the intraoral pressure (Baro1).
FIG. 10 is a diagram showing an example of time-series data of the disc tension force and the muzzle muscle potential during disc tension training. When the disc is held by the lips and the disc is pulled with a wire (when the pulling force (Pull) increases), the lip contact pressure (LipF) increases and the amplitude of the ring muscle potential (EMG) increases. . The sharp drop in the rightmost tensile force is a measured value at the moment when the disk jumps out of the mouth. Since the working electrode is suddenly removed, the amplitude is remarkably increased. The maximum value of the tensile force means the maximum disc holding force.
From these cases and the like, it can be seen that time series data of the orbital myoelectric potential, the lip contact pressure, and the intraoral pressure during exercise are helpful in determining the symptom recovery effect of the subject by the exercise.

  By using the oral care support tool of the present invention, it is possible to measure the limbal muscle potential, the intraoral pressure, the lip contact pressure, the lip tension, and the like, and evaluate the function of the lips based on the measured values. These measured values or evaluations can be used as one reference index when planning a method for lip function recovery. Functional recovery methods include, for example, physical therapy, occupational therapy, speech therapy, nutritional formulas, dietary changes, improved oral hygiene, electrical stimulation, biofeedback, and pharmacological treatment. Examples of dietary changes include high aggregation, high viscosity, trigeminal nerve stimulant, swallowing stimulant, food temperature change, food texture change, and food perception change. Improvements in oral hygiene can include gargle, toothpaste, probiotics, saliva stimulants, toothbrushes, dental floss, tongue scraping and the like. The oral care support tool of the present invention is not limited to the planning support of the function recovery method, but may include support of any known treatment method for treating the dysfunction.
