Effects of Mandibular Exercises Effect on Pain Perception and Sensitivity in Mandibular Myofascial Pain

7 de novembro de 2017 atualizado por: Juan Fernando Oyarzo, Universidad Nacional Andres Bello

Effects of Mandibular Exercises Effect in Pain Perception and Sensitivity in Women With Myofascial Pain, a Double Blind Randomized Clinical Trial.

The effectiveness of mandibular exercises as a treatment of muscular Orofacial Pain is yet unknown. This study hypothesized that training exercises can be an effective therapy improving pain perception.

Visão geral do estudo

Descrição detalhada

Temporomandibular disorders (TMDs) represent heterogeneous musculoskeletal disorders, where most common presentation is mandibular muscle pain, which is also more common among female than men. Many interventions have been proposed for this pain control, regarding drugs, oral splints, relaxing exercises and self awareness but little is known about mandibular active contraction exercises. The aim of this study is to evaluate the effects of mandibular exercises in pain perception and sensitivity in women. A double blind randomized clinical trial will be conducted among fertile university student women with Oral Contraceptives (OC) use -to control hormonal influences-, with report of facial pain and myofascial pain diagnosis (RDC/TMD). They will be assessed in Visual analogue scale (VAS), sleep quality, Pressure Pain Threshold (PPT) and pressure pain tolerance (PPTol), and then allocated in one of the three interventions for 21 days: isometric mandibular active exercises over silicone bars; video-guided isotonic mandibular contractions over cloth pegs or counseling about disorders nature as passive comparison. After 21 days, VAS, PPT and PPTol in bilateral temporalis and masseter muscles will be assessed for a second time,) and compared with initial pain status.

Data will be entered by single blind operator, and will be open for quality auditing. Site monitoring will be performed by the University clinical entities.

Data checks will be also performed as planned. Descriptive and analytical statistics will be performed to address the primary and secondary objectives.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Change in the weekly mean subjective pain index after 21 days of treatment
Prazo: Visit 1 (study day 0) and Visit 4 (study day 3) ( duration study 21 days)
Weekly mean subjective pain computed as the arithmetic mean of daily pain subjective values (visual analog scale - VAS) in Visit 1and prior to each study visit. Daily pain index is computed as pain intensity (0-100 numeric rating scale where 0 = "no pain" and 100 = "the most intense pain imaginable") for the different muscular sites tested.
Visit 1 (study day 0) and Visit 4 (study day 3) ( duration study 21 days)
Change in the weekly mean pressure pain threshold (PPT) after 21 days of treatment
Prazo: Visit 1 (study day 0) and Visit 4 (study day 3) ( duration study 21 days)
Weekly mean pressure pain threshold is computed as the arithmetic mean of daily pressure pain threshold values for muscular sites in Visit 1and prior to each study visit. Pressure values, measured in kilogram-force (kgf), from up to 3 experimental pressure stimuli, bilaterally applied to the area of temporalis muscle, will be averaged to obtain a single pressure pain threshold value per anatomical site.
Visit 1 (study day 0) and Visit 4 (study day 3) ( duration study 21 days)
Change in the weekly mean pressure pain tolerance (PPTol) after 21 days of treatment
Prazo: Visit 1 (study day 0) and Visit 4 (study day 3) ( duration study 21 days)
Weekly mean pressure pain tolerance is computed as the arithmetic mean of daily pressure pain tolerance values for muscular sites in Visit 1and prior to each study visit. Plot is captured as a pressure value, measured in kilogram-force (kgf) in 1 experimental pressure stimuli, bilaterally applied per anatomical muscle site.
Visit 1 (study day 0) and Visit 4 (study day 3) ( duration study 21 days)
