About this study

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.

Read the detailed description

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.

Intervention:

  • DCD: The patient is positioned in prone position on stretcher. Firstly, it will apply almonds oil on the MTP1 of the upper trapezius affected. Then, it will put the "musculotendinous injury FAST" program which lasts 6 minutes; and, it will move the ultrasound applicator in contact with the skin with a velocity approximately between 2.5 and 4 centimeters per second.
  • US: The patient is positioned in prone position on the stretcher. Firstly, it will select parameters (frequency: 1MHz, intensity: 1.0 W/cm2, mode: continuous). Then it will apply a slow technique of circular movements with a speed of approximately between 2.5 and 4 centimeters per second over the area of the MTP1 of the upper trapezius affected during 6 minutes.

Assessment:

To assess the effectiveness of these techniques, several tests will be performed on the subjects:

  • Myotonometric measurements using a myotonometer to obtain frequency, decrement (elasticity) and stiffness of the evaluated points and MTPs.
  • Algometry results will bring information of the PPT of evaluated MTPs.
  • The 0-10 Numeric Pain Rating Scale results will bring information of the subjective dolor perception of the subjects.
  • Inclinometer results will bring information of the ROM of cervical spine lateral inclination.
  • The Neck Disability Index results will provide information on how much neck pain interferes in the daily activities of patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ultrasound TherapyDevice

    Ultrasound equipment will be used, choosing a continuous mode, with a frequency of 1MHz and an intensity of 1.0 W/cm2. The technique will be applied during 6 minutes with circular movements and a speed of approximately between 2.5 and 4 centimeters per second.

  • Digital Capacitive Diathermy TherapyDevice

    The DCD equipment will be used choosing the "musculotendinous injury FAST" program which lasts 6 minutes. The applicator will move with a velocity approximately between 2.5 and 4 centimeters per second.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Stiffness

    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.

    Measured: Pre-intervention; Post-intervention (30 minutes after intervention); Follow up (1 week after the intervention).

  2. Change in Decrement (elasticity)

    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.

    Measured: Pre-intervention; Post-intervention (30 minutes after intervention); Follow up (1 week after the intervention).

  3. Change in Frequency

    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%.

    Measured: Pre-intervention; Post-intervention (30 minutes after intervention); Follow up (1 week after the intervention).

Secondary outcomes (4)
  1. Change in the Pressure Pain Threshold (PPT)

    The PPT is measured using a pressure algometer 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.
    • MTrP 2 of the lateral gastrocnemius of the affected side. The subject will be lying in a prone position for more stability and with a pillow under his feet. The algometer must remain perpendicular to the surface to be measured. It will be measured three consecutive times, with an interval of 30 seconds between each measurement.

    Measured: Pre-intervention; Post-intervention (30 minutes after intervention); Follow up (1 week after the intervention).

  2. Change in the Range Of Motion (ROM) of cervical spine lateral inclination

    It will be used a portable inclinometer to assess the ROM of the contralateral active cervical spine inclination. The subject will be in a relaxed and comfortable sitting position, leaning on the backrest, arms resting on his knees and fixing a point with his eyes. It will be measured three consecutive times, with an interval of 30 seconds between each measurement.

    Measured: Pre-intervention; Post-intervention (30 minutes after intervention); Follow up (1 week after the intervention).

  3. Change in Pain Perception

    Change in pain perception using Numeric Pain Rating Scale (NPRS). The NPRS is a scale from 0-10 ("0" = no pain; "10" = the most intense pain imaginable).

    Measured: Pre-intervention; Post-intervention (30 minutes after intervention); Follow up (1 week after the intervention).

  4. Change in Neck Disability Index (NDI)

    The NDI consists of ten questions in the following domains: Pain Intensity, Personal Care, Lifting, Reading, Headaches, Concentration, Work, Driving, Sleeping, and Recreation.

    Measured: Pre-intervention; Follow up (1 week after the intervention).

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Stiffness (time frame: Pre-intervention; Post-intervention (30 minutes after intervention); Follow up (1 week after the intervention).). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
