Objectives: To compare the effects of cervical manipulation on the ranges of motion of mouth opening and painful pressure points in the masseter and temporal muscles after of cervical manipulation compared to the control group. Material and methods: Single-blind randomized clinical trial with two arms, one group intervention and a control group. Hypothesis: There is a significant difference in mouth opening and painful pressure points between the intervention group and the control group. Expected results: The intervention group would significantly increase their mouth opening maximal and decrease pressure pain in the masseter and temporalis muscles.

normal mouth opening in millimeters
With a buccal goniometer, the maximum mouth opening will be measured in millimeters.
Time frame: Change from Baseline mouth open at 5 minutes
masseter muscle pressure points
Pain points will be measured under pressure with a pressure pain meter or algo meter. This measurement will be measured in kilograms.
Time frame: Change from Baseline pain points at 5 minutes
