NCT03721887

Brief Summary

In this project, the investigators will deliver a 5-day session of transcranial direct current stimulation (tDCS) to the leg motor cortex of the FOG patients to examine whether the intervention will benefit the patients in a double blind randomized design. Six assessments with different combinations of clinical scaling, gait analysis, electrophysiological investigation and fMRI examinations before and after tDCS will be conducted. The treatment and placebo groups will be crossed over after one-month washout. The investigators will investigate whether the possible tDCS beneficial effect will be different or similar in patients with different electric sources. In addition, how long the possible beneficial effect of tDCS can be consolidated after the 5-day course of stimulation is also crucial. The investigators aim to peep the myth of FOG in PD and MSA by the multi-modality approach and hope the study will benefit the long suffering patients.

Outcome Measures

Primary Outcomes (1)

  • EEG recording before and after the tDCS session

    Gait recording by 64 channels EEG device. Four different frequency bands ( theta, alpha, beta, and gamma) will be investigated. Variables in gait analysis: 1.Gait initiation, 2.Level walking, 3.Gait termination.

    baseline to week 4

Secondary Outcomes (3)

  • Electromyography recording before and after the tDCS session

    baseline to week 4

  • Change in Unified Parkinson's Disease Rating Scale (UPDRS) Part III before and after the tDCS session

    baseline to week 4

  • Change in Unified Multiple System Atrophy Rating Scale (UMSARS) subscores (UMSARS-1 and UMSARS-2) before and after the tDCS session

    baseline to week 4

Other Outcomes (4)

  • Change in New freezing of gait questionnaire (NFOG-Q) before and after the tDCS session

    baseline to week 4

  • Change in Tinetti's Mobility Index total score before and after the tDCS session

    baseline to week 4

  • Change inParkinson's Disease Questionnaire 39 (PDQ-39) before and after the tDCS session

    baseline to week 4

  • +1 more other outcomes

Study Arms (2)

real tDCS

EXPERIMENTAL

In transcranial direct current stimulation, the anodal pad was tapped over the primary motor cortex and the cathode pad was adhered of the contralateral frontal region. A constant current of 2.0 mA will be apply for up to 20 mins.

Device: Transcranial direct current stimulation

sham tDCS

SHAM COMPARATOR

In transcranial direct current stimulation, the sham stimulation will be 30s stimulation with ramp up and ramp off for 10s at 2.0 mA.

Device: Transcranial direct current stimulation

Interventions

A consecutive 5-days course of tDCS will be delivered. In treatment group, true stimulation will be administrated and sham stimulation will be delivered in control group.
