Preparatory postural adjustments in parkinsonian patients with postural instability.
BACKGROUND Postural instability is a common problem in patients with Parkinson's disease. This paper reports results of a study undertaken to investigate some of the possible mechanisms responsible for this instability. METHODS Preparatory postural adjustments associated with a lateral leg raising task were studied in five parkinsonian patients and four age-matched controls. Recordings includ...
متن کاملAssessment of postural instability in Parkinson ’ s disease patients /
Postural instability is one of the hallmarks of Parkinson’s disease (PD). The purpose of this study was to evaluate and analyze objectively the effect of different sensory and motor components on postural instability in PD and to determine the validity of using different scales as the Unified Parkinson’s Disease Rating Scale (UPDRS), Berg Balance Scale (BBS) and the Push and Release test as val...
متن کاملAnticipatory postural adjustments in conditions of postural instability.
OBJECTIVES The purpose of this study was to investigate anticipatory postural adjustments (APAs) in standing subjects who performed a standard motor action triggering a standard postural perturbation (releasing a 2.2 kg load from extended arms) in conditions of different stability requirements. METHODS The degree of stability was varied either by balancing on special boards with long and narr...
متن کاملCinerama sickness and postural instability.
UNLABELLED Motion sickness symptoms and increased postural instability induced by motion pictures have been reported in a laboratory, but not in a real cinema. We, therefore, carried out an observational study recording sickness severity and postural instability in 19 subjects before, immediately and 45 min after watching a 1 h 3D aviation documentary in a cinema. Sickness was significantly lar...
متن کاملPostural instability precedes motion sickness.
We evaluated the hypothesis that postural instability precedes the onset of motion sickness. Subjects standing in a "moving room" were exposed to nearly global oscillating optical flow. In the experimental condition, the optical oscillations were a complex sum-of-sines between 0.1 and 0.3 Hz, with an excursion of 1.8 cm. This optical motion was of such low frequency and magnitude that it was so...
