Reference	Objective	Methods (task/recordings/signal analysis)	Principal results
Lau, 2015 [104]	Nature of oscillations in the PPN and STN (14 patients)	Gait LFPs of PPN and STN Time frequency analysis	The majority of PPN neurons are modulated during gait, contrary to STN neurons
Shoushatarian, 2011 [184]	Cortical changes during gait initiation in 20 patients PD (with and without gait initiation difficulties) and controls (young and old)	Gait initiation Scalp EEG ERP	Differences in MRCP peak amplitude only between young and PD patients (mixing with gait initiation difficulties or not) at Cz
Tard, 2016 [208]	Interference of cognitive function and motor preparation in 15 FOG and 15 non FOG PD patients	Gait initiation Scalp EEG ERP Time frequency analysis	Abnormal increased beta oscillation during motor preparation in FOG group No differences in P3 in the 2 groups
Butler, 2017 [23]	Interference of cognitive function and motor preparation in 10 FOG and 10 non FOG PD patients	Gait initiation Scalp EEG ERP	Motor preparation potential is larger in freezers during gait initiation No differences in P3b in the 2 groups

PPN: pedunculopontine nucleus; PD: Parkinson’s disease; LFP: local field potential; FOG: freezing of gait; STN: subthalamic nucleus; MRCP: movement related cortical potentials; ERP: event-related potential.
