Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

Advanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

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

Gait-related brain activity in people with Parkinson disease with freezing of gait.

PLoS ONE, 2014
Approximately 50% of people with Parkinson disease experience freezing of gait, described as a transient inability to produce effective stepping. Complex gait tasks such as turning typically elicit freezing more commonly than simple gait tasks, such as ...

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

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 ...

Gait Recognition by Dynamic Cues

, 2008
Many studies have now shown that it is possible to recognize people by the way they walk. As yet there has been little formal study of people recognition using the kinematic-related gait features.

Metabolic connectivity of freezing in Parkinson's disease

Journal of Parkinson’s Disease
Background Freezing of gait (FoG) is among the most disabling gait disorders of Parkinson's disease. The full understanding of its mechanisms requires a network study approach.

Gait-cycle-locked cortico-subthalamic signatures underlying freezing of gait and their modulation in Parkinson's disease

Neurobiology of Disease
Objective: Research on freezing of gait (FOG) in Parkinson's disease (PD) has identified relevant electrophysiological markers. However, their brief temporal windows limit their utility for individualized deep brain stimulation (DBS). This study explored
