Measuring Lip strength

NOTE: In the following method of measuring lip strength, the bulb is not
placed directly between the lips. The described method is valid,
however, because the pressure developed in the bulb depends upon
the strength of the circumferential muscle complex that surrounds
the mouth. It is tension in these muscles that allows the lips to be
compressed against one another.
1. With the IOPI® on, push the Peak Mode button [ ]. In this mode,
the LCD will display the highest pressure applied to the IOPI®.
2. Press the Peak Reset button [ ]. The LCD display will read "0".
3. Position an IOPI® Tongue Bulb inside the patient's cheek just lateral to
the corner of the mouth.
WARNING: hold onto the
stem of the Tongue Bulb.
4. Tell the patient: "Press the Tongue Bulb against your teeth by pursing
your lips as hard as you can for about 2 seconds."
• Visual and verbal encouragement during the test is acceptable,
and helps some people.
• The 2 second hold time is not important; it just avoids the question
"How long should I hold it?" when you tell them to squeeze the bulb.
5. After the patient has made his or her maximum response and relaxed,
record the value you see on the IOPI® LCD display, and then push the
Peak Reset button [ ].
6. Let the patient rest for 30 – 60 seconds, and then repeat Steps
3 – 5 two more times.
7. The Peak lip strength is the highest of the three recorded values. If the
values consistently decrease over the three trials, the rest period may
not be long enough.
