Gait declines faster over time in people with Parkinson’s disease converting to a freezing of gait phenotype
Objective: To monitor gait progression in people with Parkinson’s disease (PwPD) who convert from a non-freezing (noFOG) to a freezing of gait (FOG) phenotype. Background:…Temporal segmentation of FOG using AFSD algorithm on RGB data and on walkway pressure data
Objective: Identify and quantify FOG episodes on RGB, walkway pressure data and display the results in a web interface. Background: Freezing of Gait is a…Altered visual network dynamics associated with freezing of gait in Parkinson’s disease
Objective: We aimed to characterize the dynamic functional connectivity (DFC) in people with FOG based on high temporal-resolution functional MRI (fMRI). Background: Freezing of gait…Cortical oscillatory feature-based classification of Parkinson’s disease with freezing gait
Objective: The objective of this study was to determine the resting-state cortical oscillations and the machine learning model that best classifies Parkinson’s disease (PD) patients…Modulation of the mesencephalic locomotor region activity during gait in parkinson’s disease patients
Objective: Deciphering the role of the MLR in gait and balance disorders in PD patients Background: Lesion or dysfunction of the MLR, including the Pedunculopontine…FREEZESTEP = DALFLEX
Objective: Freezing of gait(FOG) is defined as a brief, episodic absence or marked reduction of forward progression of the feet despite the intention to walk.…Decreased mesencephalic locomotor region activation explains loss of presynaptic inhibition during step initiation in people with Parkinson´s disease with freezing of gait
Objective: To investigate if decreased mesencephalic locomotor activation (MRL) activation during step initiation in an-event related fMRI protocol would explain the loss of presynaptic inhibition…Factors contributing to prefrontal cortical activity during walking and its response to dual-tasking in Parkinson’s disease
Objective: We examined the contribution of clinical, cognitive, and gait characteristics to prefrontal cortex (PFC) activity during walking and its response to dual-task in people…Brain activity of the emotional circuit in Parkinson’s disease patients with freezing of gait
Objective: The aim of this observational study was to assess brain functional MRI (fMRI) activity during a “FoG observation task” in PD-FoG patients relative to…Longitudinal structural and functional brain alterations in Parkinson’s disease patients with freezing of gait
Objective: To investigate the cortical/subcortical grey matter (GM) changes and network functional alterations in PD-FoG patients, in PD developing FoG (PD-FoG-converters) and PD not developing…
