Assuming the subject to be in the anatomical position, with the neck neither hyperextended nor hyperflexed, the important landmarks and their corresponding vertebral levels are as follows: • The thyroid notch is readily palpable and often visible. For the evaluation of neck structures,masseter and temporalis muscles, pressure pain threshold (PPT) values were measured with a hand-held pressure algometer.Obtained data were analyzed statistically applying Mann-Whitney U test, Wilcoxon, and chi-squared tests with a significance level of 0.05. 4.
