Effect of Cervical Manipulation on Mouth Opening

Not Applicable

Completed

• Conditions: Bruxism; Face Pain
• Interventions: Other: Sham intervention; Other: cervical manipulation

• Registration Number: NCT05416788
• Lead Sponsor: University of Americas

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Control group	Sham intervention	placebo manipulation, the cervical spine will be tilted and rotated without reaching the end feel or the pump
Cervical manipulation group	cervical manipulation	high-velocity, low-amplitude cervical manipulation

Primary Outcome Measures

Name	Time	Method
normal mouth opening in millimeters	Change from Baseline mouth open at 5 minutes	With a buccal goniometer, the maximum mouth opening will be measured in millimeters.

Secondary Outcome Measures

Name	Time	Method
masseter muscle pressure points	Change from Baseline pain points at 5 minutes	Pain points will be measured under pressure with a pressure pain meter or algo meter. This measurement will be measured in kilograms.
