About this study

Official title: Repetitive Transcranial Magnetic Stimulation for the Treatment of Freezing of Gait in Parkinson's Disease: A Randomized Controlled Trial

Freezing of gait (FOG) is a common and devastating symptom in advanced stage Parkinson's disease (PD), which contributes to falls and disability. Unfortunately, there is no effective pharmacological treatment for FOG. It is suggested that the cortex-basal ganglia circuit, especially the frontal lobe, plays an important role in the pathogenesis of FOG. Repetitive transcranial magnetic stimulation (rTMS) effects over the cortex and affects the subcortical neural circuits. Previous studies have demonstrated that rTMS can improve FOG for PD patients. In the present randomized controlled trial (RCT) study, the invastigators aim to investigate the efficiency of rTMS over different motor regions of frontal lobe. The efficacy of treatment is evaluated by the score of FOG questionnaire and FOG provoking test, and the changing of neural network shown by functional magnetic resonance imaging (FMRI). Then the effects of rTMS over different brain regions will be compared for choosing a better target. The study will provide the evidence for non-invasive neuro-modulation of Parkinson's disease with freezing of gait (PD-FOG).

Study groups in NCT04431570
Study groupRoleWhat they receive
rTMS over M1 regionExperimentalThe stimulus intensity was set to 100% of the resting motor threshold. Ten sessions of rTMS were delivered over 2 weeks, one session per day for 5 consecutive days per week. Each session consisted of 10 trains of 100 pulses at 10Hz with an inter-train interval of 40 seconds. In this group, the target of rTMS is M1 region.

What is being measured

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

  1. the change of freezing of gait questionnaire (FOGQ)

    a self-assessment scale for evaluating FOG severity,the minimum value is 0, the maximum value is 24, and higher scores mean a worse outcome.

    Measured: through study completion, an average of 2 weeks

Secondary outcomes (6)
  1. the change of freezing of gait score (FOG score)

    assess the severity of FOG, the minimum value is 0, the maximum value is 36, and higher scores mean a worse outcome.

    Measured: through study completion, an average of 2 weeks

  2. the change of score of Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part III

    assess the motor ability, the minimum value is 0, the maximum value is 132, and higher scores mean a worse outcome.

    Measured: through study completion, an average of 2 weeks

  3. the change of Hamilton Depression (HAMD) Scale

    assess the severity of depression, the minimum value is 0, the maximum value is 76, and higher scores mean a worse outcome.

    Measured: through study completion, an average of 2 weeks

  4. the change of Mini-mental State Examination (MMSE) scale

    assess the severity of mental state, the minimum value is 0, the maximum value is 30, and higher scores mean a worse outcome.

    Measured: through study completion, an average of 2 weeks

  5. the change of Parkinson's Disease Questionnaire (PDQ-39)

    assess the quality of life, the minimum value is 0, the maximum value is 156, and higher scores mean a worse outcome.

    Measured: through study completion, an average of 2 weeks

  6. functional image of the brain (FMRI)

    graph theoretical analysis of the brain network

    Measured: through study completion, an average of 10 days

Questions about this trial

What is this clinical trial studying?

A study testing rTMS in people with Parkinson Disease and Gait Disorders, Neurologic, run by Peking Union Medical College Hospital at 1 site in China.

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 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: status not confirmed, as of the sponsor's last update on 16 Jun 2020. 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 China. 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 Han Wang, doctor (+8618600044179, 18600044179@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the change of freezing of gait questionnaire (FOGQ) (time frame: through study completion, an average of 2 weeks). 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 16 Jun 2020.
