Conditions
Summary
Temporomandibular disorders (TMD) encompass dysfunction and pain of the masticatory muscles and temporomandibular joint (TMJ). Pain in the TMJ, restricted jaw movement, and joint sounds are common conditions in this disorder. This can impact patients' ability to perform daily activities such as eating, speaking, laughing, or yawning, significantly affecting their quality of life. The TMJ and masticatory muscles are innervated by the auriculotemporal branch and the mandibular nerve (V3), a branch of the trigeminal nerve. An estimated 60% to 70% of the population shows signs of TMD, of which up to 12% report intense symptoms requiring treatment. Percutaneous electrical nerve stimulation (PENS) could be a clinically relevant therapy in TMD patients applied through minimally invasive physiotherapy. To our knowledge, there are no trials evaluating the non-surgical clinical efficacy of PENS on the mandibular nerve. The project's objective is to assess the effectiveness of PENS on the mandibular nerve in this type of condition.
Eligibility
Inclusion Criteria6

Interventions
Percutaneous nerve stimulation (PENS) involves inserting a dry needling needle through muscle tissue until it reaches a nerve branch. At this point, a bipolar TENS current with different parameters is applied to the needle with the goal of improving the patient's pain perception.
Digital pressure techniques in muscle areas with the aim of reducing the perception of stiffness and pain
Exercises for improving mandibular mobility, occlusion coordination and regulation of temporomandibular muscle tone
