PURPOSE Computerized static stabilometry is a clinical test in neurologic and muscular diseases to assess postural stability or body sway in a quantitative manner. The purpose of this study was to examine whether postural stability would change in the process of the prism adaptation test in patients with intermittent and constant exotropia. METHODS Postural stability was measured before the p...

Multiple system atrophy (MSA) is characterized clinically by parkinsonism, cerebellar, autonomic, and corticospinal features of variable severity. When the presentation is only parkinsonism, the disease might be difficult to differentiate from Parkinson's disease (PD). We present a case of an 80-year-old man with previous diagnosis of PD. One year after the diagnosis, he had a whiplash cervical...

BACKGROUND AND PURPOSE Asymptomatic cerebral small-vessel disease (cSVD) in elderly individuals are potent risk factors for stroke. In addition to common clinical risk factors, postural instability has been postulated to be associated with cSVD in older frail patients. Here, we conducted a cross-sectional study to understand the possible link between postural instability and asymptomatic cSVD f...

Background It is not known why continuing instability exists after ankle sprain. The most common hypotheses include impairments in proprioception, muscle power or postural control [1] but a relationship has not been established. Therefore, the aim of this study was to investigate the relationship between functional instability and invertor/evertor peak power, accuracy of movement detection and ...

BACKGROUND Postural instability while standing, walking, and interacting with objects or the environment places individuals with Parkinson disease (PD) at risk for falls, injuries, and self-imposed restrictions in activity. Recent research with motor skills, including those demanding postural stability, has demonstrated performance and learning advantages when performers are instructed to adopt...

Recurrent low back pain (LBP) is a common musculoskeletal problem, and there is a 24% to 87% recurrence rate within one year [1,2]. Those who have recovered from an episode of LBP demonstrated altered paraspinal muscle spindle afference and central processing of this sensory input for balance performance [3-5], altered proprioceptive postural control that might be caused by anticipation of post...

Motion sickness typically occurs when the body is subjected to externally imposed motions, but there are situations in which sickness occurs in the absence of imposed motion. We report a new and unanticipated instance of the latter. Subjects in a study of spontaneous standing postural sway sometimes reported dizziness and motion sickness. Reports of sickness were correlated with changes in post...

INTRODUCTION Postural instability is one of the most disabling features of Parkinson's disease. OBJECTIVE To evaluate postural balance in Parkinson's disease. METHODS Thirty patients with Parkinson's disease were compared with controls using Tetrax™ interactive balance system posturography. RESULTS For different positions, patients with Parkinson's disease showed a significantly higher we...

purpose: over the past 20 years, the center of pressure (cop) has been commonly used as an index of postural stability in standing. while many studies investigated cop excursions in patients with knee osteoarthritis and healthy individuals, no comprehensive analysis of the differences in their postural sway pattern exists. the present study aimed to review the previously published studies conce...

A previously healthy 60 years old female patient presented with bradykinesia, postural instability and increased rigidity of both upper and lower limbs for 2 years and was diagnosed as Parkinsonism for last years. Later on she developed features of autonomic dysfunction including postural hypotension, hyperhydrosis and urinary incontinence so was diagnosed as Shy-Drager Syndrome. She was treate...
