Effects of Focal Extracorporeal Shock Wave Therapy in the Treatment of Temporomandibular Disorders of Muscular Origin
Effects of Focal Extracorporeal Shock Wave Therapy in the Treatment of Temporomandibular Disorders of Muscular Origin: a Randomized, Double-blind, Controlled Clinical Trial
University of Sao Paulo General Hospital
100 participants
Apr 20, 2023
INTERVENTIONAL
Conditions
Summary
The objective of the study is to evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) in improving pain in patients with TMD pain after 5 weeks of treatment, 1 month and 3 months after the end of treatment. As secondary objectives, we plan to evaluate the effectiveness of focal shockwave therapy in relation to: 1. Range of motion (ROM) of the temporomandibular joint using goniometry after 5 weeks of treatment; 2. Degree of inflammation, using ultrasound evaluation in the temporomandibular joint relating to the degree of pain after focal shockwave therapy for 5 weeks; 3. Jaw movement (MM), joint noise (RA), joint pressure (PA) and disability index (DI) will be measured at each treatment session and after 5 weeks of treatment, 1 month and 3 months after the end of treatment in the affected joints; 4. Quality of life will be assessed using the "Short Form Health 36" questionnaire (SF-36) during the 5 weeks of treatment, 1 month and 3 months after the end of treatment; 5. Pain control medication will also be considered and compared before and after the proposed treatment for 5 weeks. Safety will be assessed throughout the study by monitoring the incidence of study-related adverse events. All patients will be contacted periodically and encouraged to report any side effects.

Interventions
We will apply 2000 focal shock wave impulses starting in each region of the affected masticatory muscles and looking for compromised muscles in the masticatory muscles such as: masseter, temporal, pterygoid (medial and lateral and digastric through a piezoelectric generator F7, G3 with a focus of 1.5cm in depth, frequency of 8Hz and intensity of 0.048mJ/mm² as long as it is tolerable to the patient (it can be reduced to a tolerable intensity of at least 0.018mJ/mm²) starting with a density of energy flow between 0.12 to 0.15 mJ/mm2, starting from an adaptation dose of 0.10 mJ/mm2 in the first 500 impulses. The non-stationary technique will be used, slowly moving the applicator. Shockwave therapy will be weekly, totaling five consecutive weeks.
