Not Applicable
Conditions
Parkinson's Disease
Interventions
Device: Low-frequency repetitive Transcranial Magnetic Stimulation
Device: rTMS maintenance
Device: Sham
Device: Sham maintenance
Registration Number
NCT02221544
Lead Sponsor
Tel-Aviv Sourasky Medical Center
Brief Summary

This study is a double blind comparative study examining the effectiveness of the rTMS treatment on Freezing of Gait (FOG) phenomenon in patients with Parkinson's disease. We hypothesize that treatment using rTMS stimulation on frontal lobe areas will improve gait quality and decrease the frequency of FOG in patients with Parkinson's disease.

Detailed Description

A course of low-frequency repetitive transcranial magnetic stimulation (rTMS) delivered over the supplementary motor area (SMA) improves motor symptoms in patients with Parkinson's disease (PD).

The present study is a comparative study that examines the effectiveness of rTMS treatment technique Freezing of Gait (FOG) phenomenon in Parkinson's disease patients. We hypothesize that treatment using rTMS stimulation on frontal areas will decreasing frequency of FOGs in patients with Parkinson's disease and improve gait quality and quality of life.

Primary Outcome Measures
NameTimeMethod
Changes in frequency and severity of the freezing of gait phenomenonOne week post intervention

The new version of the Freezing of Gait questionnaire will be used to quantify the frequency and severity of this symptom. The score will be compared to baseline.

Secondary Outcome Measures
NameTimeMethod
Immediate changes in blood pressureEvery session, immediately after receiving the treatment

Measuring blood pressure will monitor subjects' autonomic response to the treatment. Measures will be compared before and after receiving the treatment

Community ambulationOne week post intervention

Will be assessed using 1) the Habitual Physical Activity Questionnaire (HPAQ). It will quantify the type and amount of regular physical activity. 2) A body-worn small lightweight device that will be worn by the subject for 7 days to monitor stepping and physical activity.

Changes in enduranceOne week post intervention

This measure will be assessed using the 2 minute walk test. The distance walked during 2 minutes will be compared to baseline performance.

BalanceOne week post intervention

Balance and lower extremity function will be assessed using performance-based measures: (1) The Four Square Step Test (FSST), (2) The Short Physical Performance Battery (SPPB), and (3) The Mini- Balance Evaluation Systems Test (mini-BEST).

Immediate change in gait functionOne week post intervention

Gait speed and variability will be assessed under usual and dual task conditions and while negotiating physical obstacles, using a sensorized 7 meter carpet (PKMAS) and wearable body fixed sensors. These measures will be compared to baseline performance.
