Trial summary

Research has shown that chronic pain is related to variety of perceptual distortions. Little is known on how acute pain experience influences perception, especially precision of touch. This project is aiming to test the hypothesis of pain as a process of biological value leading to improvement in tactile acuity. Read more about this study

About this study

Research has shown that chronic pain is related to variety of perceptual distortions. Little is known on how acute pain experience influences perception, especially precision of touch. This project is aiming to test the hypothesis of pain as a process of biological value leading to improvement in tactile acuity.

Read the detailed description

This project has following goals:

  1. To test the hypothesis of pain as a process of biological value leading to improvement in tactile acuity
  2. To investigate intra-rater reliability of tests measuring perceptual distortions in pain
  3. To investigate validity of novel tests measuring perceptual distortions in pain
  4. To explore the influence of acute neck pain on left/right recognition task
  5. To explore the effect of acute neck pain on body perception

What participants receive

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

  • Saline injectionOther

    Also called Pain induced by saline injection

    In the saline injection condition, acute neck pain will be induced via 0.5 ml hypertonic (5% NaCl) saline bolus injection which is a commonly used model of acute pain. Saline will be injected into the right (or left) trapezius muscle at the level of C7 cervical level. Injections will be performed by a physician under ultrasound imaging guidance to ensure that each single injection will be equally placed at the same depth. The side for the pain induction will be randomised across subjects. The place of needle insertion and corresponding point on the opposite side of the body will be covered by placing a small piece of adhesive plaster to ensure blinding.

  • Sham injectionOther

    Also called Pain induced by sham injection

    In the sham-injection condition (nocebo comparator), a real needle will be shown to the participants to imitate and produce the anticipation of a pain experience. A pinprick sensation will be produced by a weighted stimulus applied perpendicularly to the skin without piercing the skin. A stimulus of 512 millinewtons (mN) will be used to produce a pinprick sensation and activation of cutaneous nociceptors. Adhesive tapes covering stimulation points will also be provided. The stimuli will be applied in exactly the same spot as the real injection in previous experimental condition.

What is being measured

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

  1. Tactile acuity measured by two-point discrimination test (TPD).

    Mechanical callipers will be delicately applied to the spot just below the location where real or sham injection will be administered. Tactile stimuli will be applied until the very first blanching of the skin. Testing will be commenced with 0 mm between the two calliper's tips, and then the distance between them will be gradually increased until participants will able to verbally report that two points had been touched instead of one. Subsequently, the descending sequence will be applied until the perception of the two points disappeared.

    Measured: TPD change from baseline at 30 seconds post-manipulation period (e.g. saline injection).

Secondary outcomes (2)
  1. Laterality judgements measured by left/right recognition application.

    A set of images displaying human neck in different orientation in space will be show to participants. The goal of the task is to decide whether given picture depicts neck rotated to the left or right or flexed into left o right side. The accuracy and response time is measured.

    Measured: Measured at baseline and ~30 seconds after manipulation (e.g. saline injection).

  2. Sensory dissociation measured by two-point estimation task (TPE).

    One tactile stimulus will be applied until the very first blanching of the skin, with a 120 mm horizontal separation between the calipers' tips. Participants will be then asked to indicate with their calipers the distance they have perceived.

    Measured: Measured at baseline and ~30 seconds after manipulation (e.g. saline injection).

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 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 8 Aug 2018. 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 Poland. 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?

Tactile acuity measured by two-point discrimination test (TPD). (time frame: TPD change from baseline at 30 seconds post-manipulation period (e.g. saline injection).). 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 NCT03495076, 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 8 Aug 2018.
