A comparative study of the stereognathic ability between patients with myofascial pain dysfunction syndrome and a control group.

This study compared the stereognathic ability of two groups of subjects. One group comprised 35 myofascial pain dysfunction syndrome (MPDS) subjects and the other, 30 control non-MPDS subjects. Thirteen different acrylic resin shapes were used for oral and manual identification. No statistically significant difference was found between the two groups in the accuracy of identification, time for identification and their ratio. The results indicate no difference in stereognathic ability between the MPDS and the control group.
