TRANSCRANIAL DIRECT CURRENT STIMULATION FOR TREATMENT OF FREEZING OF GAIT IN PARKINSON’S DISEASE. A CROSS-OVER STUDY

Transcranial direct current stimulation for treatment of freezing of gait: A cross-over study

Background and objective Progression of Parkinson's disease (PD) is frequently characterized by the occurrence of freezing of gait (FOG) representing a disabling motor complication. We aim to investigate safety and efficacy of transcranial direct current stimulation of the primary motor cortex of PD patients with FOG. Methods In this cross-over, double-blind, sham-controlled study, 10 PD patients with FOG persisting in “on” state underwent anodal and sham direct current stimulation for 5 consecutive days. Clinical assessment over a 1-month period was performed. Results A significant improvement of gait, as assessed by the Stand Walk Sit test, with reduction in number and duration of FOG epi…
