Brief summary
Participants with chronic orofacial pain caused by masticatory and neck muscles will be distributed in two groups, both followed with the same occlusal and self-care treatment. The experimental group will receive 5 sessions of physiotherapy applying a specific pressure on the trigger points while the control group will receive placebo through a simulation of the same technique. Orofacial perceived pain, pain pressure thresholds, catastrophizing, kinesiophobia, cervical disability, depression and anxiety will be evaluated at baseline, immediately after treatment and 3 months later.
Interventions
A specific pressure is applied on trigger points of masticatory and neck muscles between pain pressure threshold and pain tolerance (7-8 visual analog scale).
A simulated pressure release technique is applied around masticatory and neck muscles.
