Thermoresponsive Soft and Self‐Anchoring Cuff Electrode for Chronic Peripheral Interfaces

Advanced Functional Materials, EarlyView.
A novel thermoresponsive, soft and self‐anchoring (TSSA) cuff electrode utilizing shape memory polymers achieves autonomous, sutureless peripheral nerve fixation. Driven by thermally induced pre‐strain and tissue adhesion, the device self‐closes and softens at body temperature, successfully minimizing mechanical mismatch. This adaptive platform ensures

Freezing More than Gait: A Case Report of Freezing of Urination (FOU) in Parkinson’s Disease

Parkinson's Disease, 2020
Freezing of gait (FOG) is a disabling phenomenon that is described by patients with Parkinson’s disease (PD). Not only gait may be involved in the freezing phenomenon, but also some nonmotor symptoms, such as freezing of urination (FOU) in this case. The

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

Advanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

[Freezing of gait or freezing of quadruped gait].

Neurologia (Barcelona, Spain), 2004
Parkinson's disease (PD) is frequently associated with freezing of gait. Patients with advanced PD learn to use tricks to relieve freezing of gait. Recently one of our patients informed us that he could overcome freezing of gait by crawling. Since crawling is a sort of quadruped gait that humans develop transiently, we wondered whether quadruped gait ...

Deliberate gait scissoring to overcome freezing of gait in Parkinson disease [PDF]

Neurology, 2018
A 70-year-old man with Parkinson disease (PD) presented with gait scissoring, which he used purposely to overcome freezing of gait (video). This is important for 3 reasons. First, gait scissoring is traditionally equated with a functional disorder, but can apparently also be seen in PD.1 Second, although balance impairments are common in PD, gait ...

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

Advanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Abnormal activity in the brainstem affects gait in a neuromusculoskeletal model

Journal of NeuroEngineering and Rehabilitation
Background The ability to start and stop locomotion in response to different situations is an essential survival strategy in mammals. Mammalian locomotion is controlled by central pattern generators in the spinal cord, which are modulated by higher ...

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 ...
