The intrinsic and extrinsic aspects of freezing of gait [PDF]

Movement Disorders, 2008
Freezing of gait appears to result from a number of fundamental problems in patients with Parkinson disease. Automaticity is impaired, putting more stress on voluntary mechanisms. Internal drivers of movement are impaired, likely because of deficient basal ganglia function.

Hierarchical Multi‐Material Architectures With Gradient Design for Dynamic‐Range Flexible Tactile Sensing

Advanced Materials Technologies, EarlyView.
Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...

A radiomics approach for predicting gait freezing in Parkinson’s disease based on resting-state functional magnetic resonance imaging indices: A cross-sectional study

Neural Regeneration Research
Freezing of gait is a significant and debilitating motor symptom often observed in individuals with Parkinson’s disease. Resting-state functional magnetic resonance imaging, along with its multi-level feature indices, has provided a fresh perspective and

Measuring freezing of gait during daily-life: an open-source, wearable sensors approach

Journal of NeuroEngineering and Rehabilitation, 2021
Background Although a growing number of studies focus on the measurement and detection of freezing of gait (FoG) in laboratory settings, only a few studies have attempted to measure FoG during daily life with body-worn sensors. Here, we presented a novel

Predicting the onset of freezing of gait: A longitudinal study [PDF]

Movement Disorders, 2017
ABSTRACTBackground: Freezing of gait is a disabling symptom of Parkinson's disease that ultimately affects approximately 80% of patients, yet very little research has focused on predicting the onset of freezing of gait and tracking the longitudinal progression of symptoms prior to its onset.

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

Advanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

A Case of Apparent Upper-Body Freezing in Parkinsonism while Using a Wheelchair

Frontiers in Neurology, 2017
Freezing of gait (FOG) is a common, disabling gait disturbance in Parkinson’s disease (PD) and other Parkinsonian syndromes. Freezing also occurs during non-gait movements involving the upper limbs.
