Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to find a decrease of at least 25% in pain intensity, determined by the Visual Analogue Pain Scale, which consists of drawing a 10 cm horizontal line without numbers, with the left end marking “absence of pain ” (corresponding to 0 cm) and on the right “worst possible pain” (10 cm). The measurement of the marking will be carried out with a 10 cm ruler to determine the intensity of the pain;An increase of at least 20% in the width of the mouth opening is expected, which will be performed with the help of a millimeter ruler. The volunteer will be instructed to open their mouth as wide as possible. The maximum voluntary mouth opening will be measured between the distance between the upper and lower central incisors;An increase of at least 25% in the pressure pain threshold is expected, which will be performed using a digital algometer (Kratos digital model DDK), whose flat circular tip of 1 cm2 is applied with a constant force of 0 .5 kgf/cm2/s in the body of the muscle to be tested; When this pressure begins to cause pain, the patient presses a button that stops the pressure exerted by the examiner, marking the pressure pain threshold. This test will be performed bilaterally on the masticatory muscles (masseter, temporalis) and the temporomandibular joint. The joint and each muscle will be tested twice, with a time interval of 5 minutes between tests. The average value between the two measurements will be used as the pressure pain threshold | — |
Secondary
| Measure | Time frame |
|---|---|
| A reduction of at least 1 grade is expected in the Central Awareness Questionnaire, which is composed of two parts, where part A contains 25 statements that can be scored on a 5-point temporal Likert scale (zero to four). The higher the value, the higher the SC degree, which can vary from zero to 100 points in total. Part B assesses whether the patient has previously been diagnosed with any of the diseases included in Central Sensitization syndrome and the year of diagnosis. According to the inventory score, five levels of symptom severity were established: subclinical (0-29 points); light (30-39 points); moderate (40-49 points); severe (50-59 points); extreme (60-100 points) | — |
