About this study

This study had the goal of analyse the neurophysiologic effects of both mechanical and manual cervical manipulation, in asymptomatic individuals.

Read the detailed description

In this study, the investigators compared the effects of manual manipulation and instrument assisted manipulation of C3/C4 on muscle tone, elasticity and stiffness and on pressure pain threshold , and pressure pain perception. The muscles evaluated were upper trapezius and biceps brachialis, bilaterally. The study also had a placebo and a control group. All individuals were asymptomatic.

Being tested
Cervical spine manual manipulation, Cervical spine mechanical manipulation, Placebo intervention

What participants receive

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

  • Cervical spine manual manipulationOther

    In the Manual manipulation group, the thrust was applied in the right side of C3/C4 with neutral flexion/extension, ipsilateral side bending and contralateral rotation. Then, a low amplitude, high velocity thrust in rotation was delivered.

  • Cervical spine mechanical manipulationOther

    In the Mechanical manipulation group, the Activator instrument was applied on the right transverse apophyses of C3.

  • Placebo interventionOther

    The subjects were positioned in the same pre-manipulative position as the manual manipulation group, but the thrust didn't occur. Instead, the position was hold for 3 seconds and then the subject's head returned passively to neutral position.

What is being measured

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

  1. Pressure pain thresholds

    To measure the pressure pain threshold, it was used an electronic pressure dynamometer FORCE ONE™ FDIX (Wagner Instruments - Greenwich, USA), with 1cm2 of surface. The values were expressed in Kg/cm2. The pressure was increased at a rate of 1 kg/cm2/s until the subject inform that the sense of pressure has become a sense of pain.

    Measured: Immediately after the intervention

  2. Pressure pain perception

    To evaluate the pressure pain perception, it was used a Visual Analogue Scale (VAS). The pressure increased until 2,5 kg/cm2 and was hold for 5 seconds, and the subject used the VAS scale to record the pressure pain perception he felt.

    Measured: Immediately after the intervention

Secondary outcomes (3)
  1. Muscle tone

    To measure muscle tone it was used the MyotonPro device. It was used to evaluate those parameters both on the biceps and on the upper trapezius, bilaterally. The device was located perpendicular to the middle point of each muscle and it were recorded 6 impulses in each one of them. The non-neural tone was recorded as frequency.

    Measured: Immediately after the intervention

  2. Muscle stiffness

    To measure muscle stiffness it was used the MyotonPro device. It was used to evaluate this parameter both on the biceps and on the upper trapezius, bilaterally. The device was located perpendicular to the middle point of each muscle and it were recorded 6 impulses in each one of them. The muscle stiffness was recorded as N/m.

    Measured: Immediately after the intervention

  3. Muscle elasticity

    To measure muscle elasticity it was used the MyotonPro device. It was used to evaluate those parameters both on the biceps and on the upper trapezius, bilaterally. The device was located perpendicular to the middle point of each muscle and it were recorded 6 impulses in each one of them. The elasticity was indicated by logarithmic decrement.

    Measured: Immediately after the intervention

Questions about this trial

What is this clinical trial studying?

A study testing Cervical spine manual manipulation and Cervical spine mechanical manipulation in people with Healthy Subjects, run by Escola Superior de Tecnologia da Saúde do Porto.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Pressure pain thresholds (time frame: Immediately after the intervention). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Mar 2018.
