About this study
Official title: Vacuum Myofascial Therapy Device for Non-specific Neck Pain. A Single Blind Randomized Clinical Trial
This study aim to investigate the effects of physium therapy for improving pressure pain thresholds (PPTs), range of motion,Neck Disability Index, the multidimensional health related quality of life (SF-12) and the multidimensional health related quality of life and pain in patients with mechanical neck pain (NP).
Read the detailed description
Fifty-four participants with NP will randomly allocated to either an physium therapy (five sessions) or a physical therapy (PT) groups (ten sessions) during two weeks. Multimodal PT program included: ultrasound therapy (US), transcutaneous electric nerve stimulation (TENS) and massage. Visual Analogue Scale (VAS), Neck Disability Index ( NDI), range of motion and (CROM), Questionnaire SF-12 and PPTs in sub-occipital and upper trapezius muscles were measured at baseline, at the end of treatment and at 1 month follow-up. T-tests and a repeated-measures multivariate analysis of variance (RM-MANOVA) were used for VAS, CROM and PPTs, respectively.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Physiotherapy treatment with physium device.Procedure or surgery
This group will treated five times with the analgesic program of physium therapy. Each maneuver was performed once per session by slow and progressive. The whole procedure lasted no more than 45 minutes.
Conventional physiotherapy treatmenProcedure or surgery
The PT group will treated during two weeks (ten days/week) with ultrasound therapy (US), transcutaneous electric nerve stimulation (TENS) and massage, in this order. Ultrasound will applied in pulse mode at an intensity of 1 megahertz for 10 minutes in the sub-occipital region and the vicinity of the trapezius muscles. TENS will applied with a pulse duration of 250 microseconds at a frequency of 80 Hertz for 20 minutes in the sub-occipital region and the trapezoids. Deep massage was applied at a slow speed for 20 minutes using sliding neutral creams. Massage therapy included gliding and kneading techniques applied over trapezius (upper, lower and middle fibers), splenius capitis and levator scapulae muscles with a therapeutic intention.
| Study group | Role | What they receive |
|---|---|---|
| EXPERIMENTAL GROUP | Experimental | The intervention for this group consisted of 5 massage sessions with the PHYSIUM device for a month. Receives: Procedure: Physiotherapy treatment with physium device. |
| CONTROL GROUP | Experimental | The multimodal physical therapy program includes 10 sessions of:
* ultrasound pulsatil therapy (US) for 10 minutes.
* transcutaneous electric nerve stimulation (TENS) for 20 minutes.
* massage for 20 minutes. Receives: Procedure: Conventional physiotherapy treatmen |
What is being measured
The primary outcome is the main question the study is designed to answer.
The intensity of cervical pain
A 10-point Numerical Pain Rating Scale (NPRS; 0: no pain, 10: maximum pain) will be used to assess the patients' current level of cervical pain, and the worst and lowest level of pain experienced in the preceding week in the cervical area.
Measured: Baseline
Secondary outcomes (5)
The intensity of cervical pain
A 10-point Numerical Pain Rating Scale (NPRS; 0: no pain, 10: maximum pain) will be used to assess the patients' current level of cervical pain, and the worst and lowest level of pain experienced in the preceding week in the cervical area.
Measured: Four weeks
Active cervical range of motion
Measured by goniometer type crom
Measured: Baseline and four weeks.
Pressure pain thresholds in cervical trigger points
Pressure pain thresholds (PPTs) will be measured with a pressure algometer (Baseline, Pain TestTM, Wagner Instruments). The clinimetric properties of this instrument have been evaluated previously. The PPT will the point at which pressure elicited pain and will presented as kilograms per square centimeter. All measurements will be conducted by the same well-trained physician.
Measured: Baseline and four weeks
The multidimensional health related quality of life
Questionnaire SF 12
Measured: Baseline and four weeks
This questionnaire has been designed to give us information as to how your neck pain has affected your ability to manage in everyday life.
Neck Disability Index
Measured: Baseline and four weeks.

Questions about this trial
What is this clinical trial studying?
A study testing Physiotherapy treatment with physium device. and Conventional physiotherapy treatmen in people with Cervical Syndrome, run by University of Cadiz at 1 site in Spain.
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 3 inclusion and 1 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 27 May 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
The intensity of cervical pain (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03322683, which also lists 17 linked publications.
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 27 May 2020.
