A spatiotemporal analysis of gait freezing and the impact of pedunculopontine nucleus stimulation [PDF]

open access: yesBrain, 2012
Gait freezing is an episodic arrest of locomotion due to an inability to take normal steps. Pedunculopontine nucleus stimulation is an emerging therapy proposed to improve gait freezing, even where refractory to medication.

The functional network signature of heterogeneity in freezing of gait

open access: yesBrain, 2018
Freezing of gait is a complex, heterogeneous, and highly variable phenomenon whose pathophysiology and neural signature remains enigmatic. Evidence suggests that freezing is associated with impairments across cognitive, motor and affective domains ...

Dual task interference on postural sway, postural transitions and gait in people with Parkinson’s disease and freezing of gait

open access: yesGait and Posture, 2017
National Institutes of HealthNational Institutes of Health: 2R01 AG006457Freezing of gait (FoG) is associated with less automatic gait and more impaired cognition, balance and postural transitions compared to people with PD who do not have FoG.

Freezing Gait in Parkinson's Disease

European Neurology, 2008
Freezing is a well-known problem in Parkinson''s disease (PD) and is characterized by an abrupt difficulty in starting or continuing rhythmic and repetitive movements. We utilized a questionnaire in order to assess the occurrence of the freezing gait phenomenon (FG) in a population of 100 consecutive PD patients. Our PD population included 70 males and

Primary progressive freezing gait

Movement Disorders, 1993
AbstractFreezing gait is an incapacitating symptom often observed in patients with Parkinson's disease. It has been less frequently described in association with multi‐infarct state, multisystem atrophies, and normotensive hydrocephalus. In our movement disorder clinic, we have diagnosed (and followed up to 3 years; median, 16 months), 18 patients in ...

An updated definition of freezing of gait

Nature Reviews Neurology
Freezing of gait (FOG) is among the most debilitating symptoms of Parkinson disease and related disorders, often resulting in falls and a loss of independence. FOG has an episodic and heterogeneous nature that makes it difficult to measure and treat. The field currently lacks a consensus on how to precisely define this phenomenon.

Brain imaging in patients with freezing of gait

Movement Disorders, 2008
Freezing of gait (FOG) is a disabling gait disturbance with unknown cerebral pathophysiology. In this review, we discuss the functional brain imaging studies that address gait physiology and pathophysiology of FOG. Radiotracer metabolic studies show basal ganglia-cortical circuitry involvement in different aspects of gait control.
