From the article:
"A distinct area of maxillary alveolar tenderness (MAT) has been consistently palpated in migraine, tension-type headache (TTH) and post-traumatic headache, even in the headache-free state.

This marker is frequently described as lateral pterygoid muscle spasm, although this muscle is inaccessible to palpation.8,9"
