Details and patient eligibility

About

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.

Enrollment: 60 patients
