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.

Cueing for Freezing of Gait

The Neurologist, 2012
Visual cues can ameliorate freezing of gait, an incapacitating symptom frequently seen in patients with parkinsonism. Here, we describe a patient with severe freezing of gait, who responded well to 3-dimensional cues, but not to 2-dimensional visual cues. We discuss the potential implications of this phenomenon.

Autonomous Reconfigurable Modular Conductive Hydrogels for Adaptive and Degradable Bioelectronic Interfaces

Advanced Materials Technologies, EarlyView.
Bridging rigid electrodes with soft, irregular tissues demands more than conductivity alone. Modular conductive hydrogels autonomously reconfigure into conformal electrode‐tissue interfaces, coupling mixed ionic‐electronic conduction with tissue‐like mechanics, self‐healing, and degradability.

What is the therapeutic mechanism of pedunculopontine nucleus stimulation in Parkinson's disease?

Neurobiology of Disease, 2019
Pedunculopontine nucleus (PPN) deep brain stimulation (DBS) is an experimental treatment for Parkinson's disease (PD) which offers a fairly circumscribed benefit for gait freezing and perhaps balance impairment.

Freezing of Gait and Falls in Parkinson's Disease

Journal of Parkinson’s Disease, 2014
Freezing of gait (FOG) and falls are common and disabling phenomena in Parkinson's disease (PD) and related disorders as they may lead to loss of independence. Both are usually observed in the advanced stage of the disease, although they can also be seen in the early stage.

Self-reported gait unsteadiness in mildly impaired neurological patients: an objective assessment through statistical gait analysis [PDF]

, 2012
Background Self-reported gait unsteadiness is often a problem in neurological patients without any clinical evidence of ataxia, because it leads to reduced activity and limitations in function.

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Hypokinesia upon pallidal deep brain stimulation of dystonia: support of a GABAergic mechanism

Frontiers in Neurology, 2013
In the past, many studies have documented the beneficial effects of deep brain stimulation (DBS) in the globus pallidus internus for treatment of primary segmental or generalized dystonia.

Co‐Delivery of Sustained Release Chondroitinase ABC‐37 With Human iPSC‐Derived Neural Progenitors Promotes Transplant Survival and Functional Recovery in a Rodent Model of Stroke

Advanced Science, EarlyView.
A regenerative strategy for stroke combines human stem cell–derived neural progenitor cells with sustained release of a matrix‐modifying, thermostable chondroitinase ABC‐37 enzyme. In a rat model of stroke, co‐delivery enhanced transplanted cell survival and neuronal differentiation, degraded inhibitory extracellular matrix components, and improved ...
