About this study

Official title: Electrical Stimulation of Accessory Spinal Nerve in Cortical Activation, Muscular Perfusion and Autonomic Response in Healthy Subjects: a Randomized, Crossover, Sham Controlled Trial.

This randomized, crossover sham controlled trial with sham intended to study the effect of electrical stimulation on peripheral nerve (spinal accessory nerve) with acupuncture needle in healthy subjects aims to access the effect o electrical stimulation of accessory spinal nerve in cortical activation, muscular perfusion and autonomic response in healthy subjects.

Participants will be assessed through measure changes in cortical activation, local muscular peripheral perfusion and autonomic responses before and after intervention and intervention-sham, and crossed after a period of wash-out.

The design aims to contribute to assessment of one electroacupuncture's techniques by measuring some of the physiological effects caused by peripheral stimulation.

Read the detailed description

In recent years, there are growing evidence that many diseases such as chronic pain and psychiatric disorders can be managed with non-pharmacological techniques. The possibility of inducing central neuroplastic responses through transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) has been widely studied, as well as peripheral stimulation techniques such electroacupuncture (EA) and intramuscular stimulation (IMS). However, there are few studies on physiological mechanisms, indications and limitations of each technique.

Thus, this randomized, crossover sham controlled trial, where sham intended to study the effect of electrical stimulation on peripheral nerve (spinal accessory nerve) with acupuncture needle in healthy subjects aims to access the effect o electrical stimulation of accessory spinal nerve in cortical activation, muscular perfusion and autonomic response in healthy subjects.

Participants will be assessed through measure changes in cortical activation, local muscular peripheral perfusion and autonomic responses before and after intervention and intervention-sham, and crossed after a period of wash-out.

The design aims to contribute to assessment of one electroacupuncture's techniques by measuring some of the physiological effects caused by peripheral stimulation.

Questions about this trial

What is this clinical trial studying?

A study testing Electrical Stimulation in people with Pain, run by Hospital de Clinicas de Porto Alegre at 1 site in Brazil.

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 10 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 5 Jan 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 Brazil. 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?

Cortical Activation (time frame: 12 minutes). 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 NCT03295370, which also lists 1 linked publication.

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 5 Jan 2018.
