Clinical Trial 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.


Description:

Introduction: Temporomandibular disorders (TMDs) are clinical conditions that affect the masticatory muscles, the temporomandibular joint (TMJ) and associated structures. Focal extracorporeal shock wave therapy (ESWT) can be used for the treatment of musculoskeletal disorders with good results in the literature and with the potential to treat muscular TMDs. Objective: The aim of the study is to perform a double-blind randomized controlled clinical trial to evaluate the effects of focal shock wave therapy in the treatment of pain due to temporomandibular disorders of muscular origin in adults after 5 weeks of treatment, 1 and 3 months after the end of treatment. Methods: A double-blind randomized controlled clinical trial will be carried out with 50 patients in the control group and 50 patients in the intervention group. Patients will be prospectively selected at the Orofacial Pain Outpatient Clinic of the Division of Dentistry, Instituto Central, Hospital das Clínicas, Faculty of Medicine, University of São Paulo (IC-HCFMUSP) and will be referred to the Acupuncture Center of the Institute of Orthopedics and Traumatology of HCFMUSP (IOT-HCFMUSP). The control group will initially undergo treatment with guidelines for muscular temporomandibular disorders and treatment by shockwave therapy with a "placebo" applicator for 5 weeks, while the intervention group will undergo the same guidelines and treatment by shockwave therapy. focal point on the masticatory muscles during 5 sessions, once a week (totaling 5 weeks). After the initial treatment period, the groups will be evaluated and compared in terms of improvement in pain and quality of life, in addition to follow-up after 1 month, 3 months and 6 months after the procedure. Expected results: After the standardized treatment period of 1 weekly session in 5 consecutive weeks (totalizing 5 sessions), it is expected that there will be an improvement in the pain Visual Analogue Scale (VAS) and in the quality of life of patients with muscular TMDs. As there is a stimulus for differentiation of mesenchymal stem cells, neovascularization and release of angiogenic factors to occur, the effect of ESWT is expected to be lasting throughout the reassessments at 1 and 3 months.

Intervention

Device:
Focused Extracorporeal Shockwave Therapy
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.
Placebo Focused Extracorporeal Shockwave Therapy
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 0cm depth, frequency of 8Hz and intensity of 0.048mJ/mm² with a fake gel pad applicator.

Outcome

Type Measure Description Time frame Safety issue
Primary Pain Visual Analogue Scale ("VAS") Change of pain perception after application of focal shock wave therapy ranging from 0 (painless) to 10 (painful) 3 months
Secondary Pressure pain threshold Test that uses an algometer in order to define the minimum pressure that triggers pain, at pre-established points (temporomandibular region). 3 months
Secondary Range of Motion Change of range of motion (ROM) of the temporomandibular joint using ruler 3 months
Secondary Quality of life assessed by the "Short Form Health 36" questionnaire (SF-36) Quality of life will be assessed by the "Short Form Health 36" questionnaire (SF-36) ranging from 0 to 100 3 months
Secondary Mandibular movement and joint noise Mandibular movement (MM) and joint noise (JN) will be assessed by a trained physiotherapist. The opening pattern will be evaluated through the vertical extension of mandibular movement; maximum opening without assistance; maximum opening with assistance; "overbit". Mandibular movements will be evaluated for right and left lateral excursion, in addition to referred pain in movement. Protrusions and deviations from the midline will also be evaluated. 3 months
