Tongue Strength Normal Values - IOPI MEDICAL 2.3 Manual Del Usuario

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 tongue 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.

Tongue strength Normal Values

These normal values are derived from 10 studies conducted on the US
population. New research indicates there may be national variation in these
normal values, perhaps dependent on the language spoken by the subjects/
patients. For the latest studies that IOPI® Medical is aware of, please visit our

Estimated normal
probability distributions
of maximum tongue
pressure of three age
groups of normal U.S.
subjects are shown to
the right:
These data were
derived from the
weighted average
of the means and
standard deviations of
tongue strength of normal subjects reported in 10 publications. Consult "Normal
Values" in www.IOPImedical.com for references and details of the numerical
procedures.
Most groups contained approximately equal numbers of males and females.
In some studies, males were somewhat stronger than females, by about
5-10 kPa, but only for young subjects. For middle-aged and old subjects, there
was no consistent gender difference.
Peak tongue strength values corresponding to various percentiles from the
estimated normal distributions are shown below. It is common to consider
values below the 5th percentile to be "abnormal" (shaded table cells).
