Evidence for a relationship between bilateral coordination during complex gait tasks and freezing of gait in Parkinson\u27s disease [PDF]

, 2012
BACKGROUND: Freezing of gait is a debilitating and common gait disturbance observed in individuals with Parkinson’s disease (PD). Although the underlying mechanisms of freezing remain unclear, bilateral coordination of steps, measured as a phase ...

Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

Advanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

[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 ...

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

Advanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Smart Face Masks as Wearable Respiratory Sensors: A Review of Sensor Technologies, Materials, and Future Directions

Advanced Healthcare Materials, EarlyView.
This review highlights recent advances in smart face masks that actively monitor breathing. By integrating humidity, gas, temperature, pressure, strain, and triboelectric sensors, these masks track key respiratory parameters in real time. The article summarizes sensor mechanisms, compares performance across studies, and discusses challenges and future ...

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 ...

Measuring movement fluency during the sit-to-walk task [PDF]

, 2013
Restoring movement fluency is a key focus for physical rehabilitation; it's measurement, however, lacks objectivity. The purpose of this study was to find whether measurable movement fluency variables differed between groups of adults with different ...
