Tongue Elevation Strength Tongue elevation strength is the maximum pressure of the tongue pressing against the hard palate. The IOPI measures this when the Tongue Bulb is placed in the “anterior” position – the hard palate just behind the alveolar ridge. The image to the right shows this position. You can simulate this placement if you suck on your thumb: the pad of your thumb will be pressing against the hard palate behind the alveolar ridge and your tongue will be pressing on your thumbnail instead of a Tongue Bulb. Most published reports on tongue strength have used the IOPI with the Tongue Bulb in the “anterior” position. Therefore, there is a great deal of information, derived from many different laboratories and clinics, about tongue elevation strength. This information suggests the following generalization: Repeated measurements of tongue strength in the same individual are quite reliable, particularly after the patient has done the task a few times. There is considerable variability in tongue strength in a population of adults reporting no swallowing or speech problems (see Normal Values). There is a clear central tendency, however, with an average maximum pressure of about 60 kPa, and a range of 40-80 kPa. Patients with oral phase swallowing problems have a tongue strength that is significantly lower than the normal population. Clinical Importance Knowing a patient’s tongue strength is clinically useful for several reasons: DECIDING whether tongue weakness is involved in oral stage swallowing problems and/or dysarthria: If the tongue is weak, you can start tongue strengthening therapy. If the tongue strength is normal, you can eliminate weakness as a cause of the swallowing or speech problems, and thus concentrate on other more useful therapies. DOCUMENTING that a patient’s tongue is weak, and therefore that strengthening exercises are justified. This may be important to insurance providers and administrators who are concerned with the cost of delivering such therapy. ASSESSING the results of tongue strengthening therapy over time: If tongue strength doesn’t increase over time, then perhaps the patient is not performing the prescribed exercises, or not doing them forcefully enough. If the tongue strength does increase, even a little bit, it can be "rewarding" for the patient to see concrete evidence improvement. EXERCISING the patient’s tongue. Performing tongue exercise using an IOPI® can give the patient very specific "targets" to achieve with their efforts, and give them immediate feedback about improvement. Pressure as a Measure of Strength Measuring the maximum pressure that a person can produce by squeezing a compliant bulb against the hard palate to estimate the strength of the tongue was a completely novel idea when the IOPI was patented in 1992. Since that time, many research studies have been published that have used the IOPI or IOPI-like instruments to measure tongue strength (see Publications). Tongue Exercise using BIOFEEDBACK Evidence exists to show that tongue exercise in dysphagia patients, as documented with the IOPI, can lead to improved swallowing outcomes. The IOPI allows the clinician to use protocols that have been proven to work in exercise science. The clinician sets the target pressure on the IOPI’s biofeedback light array and instructs the patient to squeeze the bulb until they turn the top green light on. The patient is visually reinforced for hitting their target. Tongue Elevation Strength Tongue elevation strength is the maximum pressure of the tongue pressing against the hard palate.

Inadequate lip strength may contribute to problems with deglutition, such as food containment during chewing. If lip weakness is severe, it also may interfere with the production of plosive speech sounds. Such weakness would probably be obvious, but being able to accurately "track" the degree of weakness would enable the clinician to determine whether the weakness is getting better or worse, and/or determine if training improves lip strength. Additionally, observing lip weakness in a patient may help identify abnormalities within the nervous system such as subtle cortical dysfunction, or disease processes gradually affecting the function of the facial nerve. Lip Strength Measurement To measure lip strength, an IOPI bulb is placed inside the cheek just lateral to the corner of the mouth and the patient squeezes the IOPI bulb against the buccal surface of the teeth by pursing the lips as hard as possible. Although the bulb is not directly between the lips, it is valid because the pressure developed in the bulb depends upon the strength of the circumferential muscle complex that surrounds the mouth, in particular the obcularis oris. It is tension in these muscles that allows the lips to be compressed against one another.
