Trial summary

Pain is a complex, multidimensional, and subjective experience; and although, investigators use a single word "pain", to describe our perception, multiple mechanisms contribute to the generation and maintenance of pain. To help diagnosing and improving pain management, there is a need for developing tools. Read more about this study

About this study

Pain is a complex, multidimensional, and subjective experience; and although, investigators use a single word "pain", to describe our perception, multiple mechanisms contribute to the generation and maintenance of pain. To help diagnosing and improving pain management, there is a need for developing tools. These tools may include measurements of substances, or biomarkers, in the blood; e.g. small molecules called microRNA and proteins. In these experiments, the investigators would like to investigate how the psychological response to stress and pain alters the impulses in the brain and the content of microRNA and proteins in the blood. The future aim is to identify patients in high risk of developing and maintaining chronic pain and to be able to treat chronic pain efficiently.

What participants receive

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

  • hypertonic salineDrug

    The site of injections will be determined by palpation of the contracted First Dorsal Interosseus (FDI) muscle. The skin will be cleaned with alcohol before injection. A bolus injection of hypertonic saline (7% NaCl) will be administered to the FDI muscle using a 1 mL syringe with a disposable needle (27G), and 30 the volume of the bolus will be 0.2 mL .

  • isotonic salineDrug

    The site of injections will be determined by palpation of the contracted First Dorsal Interosseus (FDI) muscle. The skin will be cleaned with alcohol before injection. A bolus injection of 0.2 mL isotonic saline (9 mg/mL) will be administered to the FDI muscle as control.

What is being measured

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

  1. Oscillations of the main electroencephalogram (EEG) frequency

    Electroencephalographic (EEG) recording will be performed placing a 64-electrodes cap over the scalp according to the 10-20 international system. Oscillations of the main EEG frequency bands (delta, alpha, beta, gamma) from the frontal and parietal lobes will be detected and correlated to the individual pain rate as well as the dimensions of the psychological questionnaires.

    Measured: 10 minutes of recording before isotonic/hypertonic injection

  2. Oscillations of the main electroencephalogram (EEG) frequency

    Electroencephalographic (EEG) recording will be performed placing a 64-electrodes cap over the scalp according to the 10-20 international system. Oscillations of the main EEG frequency bands (delta, alpha, beta, gamma) from the frontal and parietal lobes will be detected and correlated to the individual pain rate as well as the dimensions of the psychological questionnaires.

    Measured: 10 minutes of recording after isotonic/hypertonic injection

  3. Perturbation of the electroencephalogram (EEG) rhythms

    Electroencephalographic (EEG) recording will be performed placing a 64-electrodes cap over the scalp according to the 10-20 international system. Perturbation of the above-mentioned EEG rhythms will be measured in response to the hypertonic/isotonic saline injection and compared to a resting state baseline recording.

    Measured: 10 minutes of recording before isotonic/hypertonic injection

  4. Perturbation of the electroencephalogram (EEG) rhythms

Questions about this trial

What is this clinical trial studying?

A study testing hypertonic saline and isotonic saline in people with Pain, Acute, run by Aalborg University at 1 site in Denmark.

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 13 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: status not confirmed, as of the sponsor's last update on 2 Feb 2024. 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 Denmark. 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?

Results are not available in the source record.

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

Contact Laura Petrini, PhD (0045 99409826, lap@hst.aau.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Oscillations of the main electroencephalogram (EEG) frequency (time frame: 10 minutes of recording before isotonic/hypertonic injection). The study lists 34 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 2 Feb 2024.
