Disordered voluntary cough as freezing phenomenon in parkinsonism
[Purpose] In patients with parkinsonism, the precise mechanism of impaired voluntary cough remains poorly understood. This study used the flow-volume curve to clarify whether disordered voluntary cough reflects the freezing phenomenon. [Subjects and Methods] Case 1 was a 58-year-old female who had been suffering from progressive supranuclear palsy-pure akinesia with gait freezing. Case 2 was a ...
متن کاملThe On-Freezing Phenomenon: Cognitive and Behavioral Aspects
Freezing of gait is a warning sign of Parkinson's disease. One could distinguish off-freezing, which is associated with dopaminergic therapy and to its titration, and it is clinically related to wearing-off phenomenon. Differently, the on-freezing phenomenon seems to be related to a neural disruption of the frontal-parietal-basal ganglia-pontine projections; clinically, it does not respond to t...
متن کاملAir Bubbles in Ice by Simulating Freezing Phenomenon
Ice is a material that is rich in visual details. To achieve a photorealistic image that represents ice in computer graphics (CG) is a challenging issue. Ice in nature is usually not transparent because it contains bubbles. Bubbles are one of the characteristics that define the appearance of ice since they scatter light. To manually incorporate many bubbles in a CG representation would be a dau...
متن کاملFreezing fingers syndrome, primary and secondary Raynaud's phenomenon: characteristic features with hand thermography.
The aim of the present study was to establish a thermographic model of healthy subjects' hands and compare it with a model of the hands of patients with freezing fingers syndrome, a group usually regarded as a healthy population. A further aim was to establish the thermographic parameters that distinguish primary Raynaud's phenomenon (RP) from secondary RP. The study was conducted on a group of...
متن کاملCharacterizing freezing of gait in Parkinson's disease: models of an episodic phenomenon.
Freezing of gait (FOG) is a very disabling and common gait disorder in Parkinson's disease (PD). The first aim of this article was to provide a methodological and critical review of the most common research approach to understand FOG, ie, comparing the behavior of freezers with that of non-freezers. The review demonstrates that studies often fall short in clearly defining the freezer\non-freeze...
