About this study

Official title: Efficacy of Navigated Repetitive Transcranial Magnetic Stimulation in Treatment of Central Post Stroke Pain

The aim of the study is to evaluate the analgesic effects of navigated repetitive transcranial magnetic stimulation in central post stroke pain. MRI based navigation is used to determine the exact locations for stimulation.

Read the detailed description

Central post stroke pain is often very resistant to treatment. TMS has been shown to be a promising tool in treating difficult pain conditions. The best sites for stimulation are still not known and navigation has been used only in few studies.

The aim is to evaluate the analgesic effects of Navigated Repetitive Transcranial Magnetic Stimulation ( nrTMS ) on pain in a three armed crossover study. The navigation is done by using magnetic resonance imaging and stereotactic camera system. The three arms include stimulation to M1, S2 and sham stimulation to M1. 10 Hz repetitive stimulation is given to a specified location once a day 5 days a week for two weeks in each of the three arms. A months washout period is kept between each arm of the study.

Pain and other variables are followed before, during and after the study for 6 months.

What is being measured

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

  1. Change in average pain compared to baseline

    Patients will keep a pain diary for one week before stimulation and for two weeks after the stimulation. A nurse will call the patient one month after the last stimulation.

    Measured: 1 month after each arm of the study

Secondary outcomes (8)
  1. Quality of life (EQ-5D)

    Questionnaire EQ-5D

    Measured: One week after each arm of the study and 6 months after the last one

  2. Depression

    Questionnaire

    Measured: One week after each arm of the study and 6 months after the last stimulation

  3. Change in average pain compared to baseline

    Phone call ( Numeric Rating Scale (NRS) in rest and movement )

    Measured: 2,3,4,5 and 6 months after the last stimulation

  4. Magnetoencephalography (MEG)

    Changes in the irritability of the motor cortex and somatosensory cortex

    Measured: One week before and after each arms stimulations

  5. Number of patients with adverse effects

    Adverse effects are followed actively

    Measured: From the start to the end of the study, on average 12 months per patient.

  6. Hands´ motor function and dexterity

    Nine hole peg, Pinch and Jamar

    Measured: One week before and after each arm of the study

  7. Cold water test

    Conditioned pain modulation (CPM)

    Measured: One week before and after each arm of the study

  8. Genetics

    Evaluation of genetical properties in terms of TMS related pain reduction

    Measured: No time frame, just a blood sample

Questions about this trial

What is this clinical trial studying?

A study testing navigated rTMS of motor cortex and navigated rTMS of somatosensory cortex 2 in people with Central Post Stroke Pain, run by Helsinki University Central Hospital.

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 4 inclusion and 5 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 24 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

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?

Change in average pain compared to baseline (time frame: 1 month after each arm of the study). 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 24 Oct 2018.
