简要总结
The main objective:
To compare the effect on muscle tone between the application of digital capacitive diathermy and the application of ultrasound on the myofascial trigger points (MTP) of the upper trapezius muscle.
Hypothesis:
The application of digital capacitive diathermy on myofascial trigger points of the trapezius muscle compared to the application of ultrasound produces objective changes in muscle tone, and this change is superior to the changes generated by the US.
详细描述
It is a simple-blinded randomized crossover clinical trial where volunteer subjects, older than 18 years, have a latent or active proximal MTP1 (intermediate part of the anterior margin of the upper part of the muscle near the vertical fibers of the muscle attached to clavicle) in the upper trapezius.
It will assess if there are changes in the muscle tone of the trapezius muscle after applying digital capacitive diathermy (DCD) or ultrasound (US) in the latent or active MTP1 of the trapezius muscle in healthy adults.
Each patient will receive a single session of each treatment in the affected trapezius. The order in which treatments are received - US followed by digital capacitive diathermy, or vice versa - is determined at random.
To remove any carryover of effects, there will be a week of washing period between the two interventions.

结局指标
主要结局
Change in Stiffness
时间窗: Pre-intervention; Post-intervention (30 minutes after intervention); Follow up (1 week after the intervention).
The muscle stiffness reflects muscle resistance to the force that changes its shape (Nm). This outcome measure is obtained by a device named MyotonPro®. It is a non-invasive commercial device made to calculate myotonometric properties of the muscle.
Change in Decrement (elasticity)
时间窗: Pre-intervention; Post-intervention (30 minutes after intervention); Follow up (1 week after the intervention).
Logarithmic decrement of the dampening of muscle oscillations is an indicator of the elasticity. This outcome measure is obtained by a device named MyotonPro®. It is a non-invasive commercial device made to calculate myotonometric properties of the muscle.
Change in Frequency
时间窗: Pre-intervention; Post-intervention (30 minutes after intervention); Follow up (1 week after the intervention).
Frequency of muscle oscillations (Hz) is an indicator of the tone. This outcome measure is obtained by a device named MyotonPro®. It is a non-invasive commercial device made to calculate myotonometric properties of the muscle. The assessment is realized in these points: * MTrP 1 of the affected superior trapezius. * MTrP 3 of the affected superior trapezius. * MTrP 1 of the NO affected superior trapezius. * Point in the middle of the muscle belly of the affected superior trapezius. 10 mechanical stimuli of 0.4 N of force and 0.15 ms of duration will be applied. The MyotonPro® must remain perpendicular to the surface to be measured (the subject will be lying in a prone position for the MTrP 3, and sit down for the three other points). Each assessment will consist of 10 multiple measurements, spaced for 1 second. To be considerate as valid, the variation coefficient of the measure should not exceed 3%.
