About this study

Patients with an myofascial trigger point (MTrP) in their upper trapezius will be divided into three groups: Group A receiving MTrP injection with normal saline (control group), Group B with hypo-osmolar dextrose (5% dextrose), and Group C with hyper-osmolar dextrose (15% dextrose). Clinical outcomes and morphological changes will be measured before the injection, one hour after, one week after, two weeks after, and one month after the injection to delineate the therapeutic effects of dextrose injection for an MTrP.

Read the detailed description

This experiment is designed to evaluate the therapeutic effects of dextrose injection on an myofascial trigger point (MTrP). Patients with an MTrP in their upper trapezius will be recruited and be divided into three groups: Group A receiving MTrP injection with normal saline (control group), Group B with hypo-osmolar dextrose (5% dextrose), and Group C with hyper-osmolar dextrose (15% dextrose). Clinical outcomes (visual analog scale, pressure pain threshold, range of motion, neck disability index) will be measured before the injection, one hour after, one week after, two weeks after, and one month after the injection. Morphological changes of an MTrP before, and after the injection will also be evaluated by sonography. Through this study, the definite therapeutic effects, and the better osmolality of dextrose injection for the treatment of an MTrP will be delineated.

What is being measured

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

  1. visual analog scale (VAS)

    To measure the pain intensity of a myofascial trigger point. The minimum value is 0, and the maximum value is 10, and higher scores mean worse outcome (more painful).

    Measured: Change from Baseline visual analog scale at one hour after intervention.

  2. visual analog scale (VAS)

    To measure the pain intensity of a myofascial trigger point. The minimum value is 0, and the maximum value is 10, and higher scores mean worse outcome (more painful).

    Measured: Change from Baseline visual analog scale at one week after intervention.

  3. visual analog scale (VAS)

    To measure the pain intensity of a myofascial trigger point. The minimum value is 0, and the maximum value is 10, and higher scores mean worse outcome (more painful).

    Measured: Change from Baseline visual analog scale at two weeks after intervention.

  4. visual analog scale (VAS)

    Measured: Change from Baseline range of motion (ROM) of the neck at two weeks after intervention.

  8. Range of motion (ROM) of the neck

    To measure the change of the range of motion of cervical spine. The minimum value is 0 degree, the maximum value is 90 degree, and higher scores mean better outcome.

    Measured: Change from Baseline range of motion (ROM) of the neck at one month after intervention.

  9. neck disability index (NDI)

    To measure the change of neck disability index (NDI) related to the myofascial trigger point. The minimum value is 0, the maximum value is 50, and higher scores mean worse outcome (increased functional disability).

    Measured: Change from Baseline neck disability index (NDI) at one hour after intervention.

    Measured: Change from Baseline neck disability index (NDI) at two weeks after intervention.

  12. neck disability index (NDI)

    To measure the change of neck disability index (NDI) related to the myofascial trigger point. The minimum value is 0, the maximum value is 50, and higher scores mean worse outcome (increased functional disability).

    Measured: Change from Baseline neck disability index (NDI) at one month after intervention.

Questions about this trial

What is this clinical trial studying?

A study testing normal saline, Dextrose 5% in water and Dextrose 15% in water in people with Myofascial Trigger Point Pain, run by National Cheng-Kung University Hospital at 1 site in Taiwan.

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 7 inclusion and 9 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 Jul 2026. 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 Taiwan. 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. 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?

visual analog scale (VAS) (time frame: Change from Baseline visual analog scale at one hour after intervention.). The study lists 4 primary outcomes in all. 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 NCT05429827, which also lists 5 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 14 Jul 2026.
