rTMS for the Treatment of Freezing of Gait in Parkinson's Disease

Status Completed

Clinical Trial Summary

This study is a double blind comparative study examining the effectiveness of the rTMS treatment on Freezing of Gait (FOG) in patients with Parkinson's disease (PD). The investigators hypothesize that treatment with rTMS on supplemental motor area will improve gait quality and decrease the frequency of FOG in PD patients.

Clinical Trial Description

Freezing of gait (FOG) is a common and debilitating symptom in patients with Parkinson's disease (PD), characterized by sudden and brief episodes of inability to produce effective forward stepping. FOG is a major risk factor for falls, and greatly contributes to reduced mobility and quality of daily life. Treatment of FOG has been perceived as a very challenging task. Although various treatment approaches exist, including pharmacological and surgical options, evidence is inconclusive for many approaches and no clear treatment protocols are available until now. Repetitive transcranial magnetic stimulation (rTMS), a noninvasive neural modulation technique, has been closely applied as a treatment for various neurologic and psychiatric disorders. A recent meta-analysis demonstrated that rTMS could improve motor symptoms for PD patients with a moderate effect size. To date, however, only few rTMS studies have focused on its efficacy on FOG in patients with parkinsonism, and most of them targeted the primary motor cortex or dorsolateral prefrontal cortex . Even though some evidence indicates the involvement of the SMA in FOG, no report has described the SMA rTMS in PD patients with FOG. Moreover, few studies combined functional magnetic resonance imaging (fMRI) and rTMS to unravel the mechanism of its beneficial effects. To address these issues, the investigators conducted a randomized, double-blind, sham-controlled study to explore the efficiency of SMA-rTMS on FOG in PD patients. ;
