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.

Laserlight visual cueing device for freezing of gait in Parkinson's disease: a case study of the biomechanics involved [PDF]
, 2015 Background: Freezing of gait (FOG) is a serious gait disorder affecting up to two-thirds of people with Parkinson's disease (PD). Cueing has been explored as a method of generating motor execution using visual transverse lines on the floor.

Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor
Advanced Materials Technologies, EarlyView.We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into

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.

An objective assessment to investigate the impact of turning angle on freezing of gait in Parkinson's disease [PDF]
, 2017 Freezing of gait (FoG) is often described in subjects with Parkinson's disease (PD) as a sudden inability to continue the forward walking progression. FoG occurs most often during turning, especially at sharp angles.

Anti‐Slip Material‐Based Strategies and Approaches
Advanced Materials Technologies, EarlyView.This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

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.

Rhythmic laser cue is beneficial for improving gait performance and reducing freezing of turning in Parkinson’s disease patients with freezing of gait [PDF]
, 2017 Background and aim: Gait time components in Parkinson’s disease (PD) patients such as step time, gait rhythmicity, symmetry, and coordination are exacerbated during turning.

Clinical indicators of gait freezing in Parkinson's disease
The Moldovan Medical Journal, 2020 Background: Freezing of gait is a common (FOG) episodic gait disorder in advanced Parkinson's disease (PD). FOG is one of the main risk factors for falls; therefore FOG’s consequences can be devastating. This symptom is difficult to study in a research laboratory because of its unpredictability which makes it difficult to select patients for clinical ...
