Previous research has shown that mastication reduces shifts in the center of gravity of persons standing still. The present research was conducted to determine whether mastication improves reactive balance in the standing position in response to unanticipated external disturbances. The subjects were 32 healthy male adults (mean age 21.1 years, standard deviation (SD) 0.7 years). Latency data de...

Researchers, therapists, and physicians often use equilibrium score (ES) from the Sensory Organization Test, a key test in the NeuroCom EquiTest System (a dynamic posturography system) to assess stability. ES reflects the overall coordination of the visual, proprioceptive, and vestibular systems for maintaining standing posture. In our earlier article, we proposed a new measure of anterior-post...

Background: No single pharmacologic treatment has proven effective for the symptomatic management of progressive supranuclear palsy. Methods: We report a case of postural instability and falls secondary to PSP of the Parkinson's subtype and initial monotherapy with donepezil 10 mg daily for 3 months followed by a novel investigation of selegiline in combination for 6 additional months. Fall fre...

This multisite investigation assessed subjective, behavioral, and objective balance function in 30 blast survivors. Subjects with vertigo, dizziness, or imbalance were screened (n = 6) or evaluated (n = 27) during 1 year. Tests included a questionnaire, electronystagmography (ENG), and computerized dynamic posturography (CDP). Ninety-seven percent of subjects were located inside a building duri...

Maturational effects were investigated in two age groups (N = 30 per group) of children with normal hearing sensitivity, using rotary chair (RC), computerized dynamic posturography (CDP), and vestibular evoked myogenic potential (VEMP) measures. Children recruited within the younger group were three through six years of age, and children within the older group were nine through eleven years of ...

The aim of this study was to search for the reason for vertigo in children who complain of it. We tested 30 children who had been treated by a pediatrician for various diseases. We performed the detailed protocol of anamnesis, videonystagmography, posturography, and additional tests ordered by the pediatrician and then compared the results of these procedures with those of a group of 30 healthy...

The aim of this study was to assess the static posturography in dogs as a useful tool for diagnosis of lameness by means of the use of a pressure platform. For this purpose, a series of different parameters (pressure distribution, area of support, mean pressure, maximum pressure and statokinesiograms) were obtained from five lame dogs with unilateral elbow osteoarthritis treated with plasma ric...

Eighteen patients were evaluated for dizziness and imbalance resulting from whiplash associated disorder. Assessment consisted of standard caloric testing and Computerized Dynamic Posturography (CDP). Although the standard vestibular tests showed no abnormalities in any of these patients, thirteen of them had abnormalities on CDP. The concept of dizziness is variously attributed to problems fro...

CONTEXT Although phenotypic heterogeneity in autosomal dominant spinocerebellar ataxia (SCA) has been explained in part by genotypic heterogeneity, clinical observations suggest the influence of additional factors. OBJECTIVES To demonstrate, quantitate, and localize physiologic abnormalities attributable to nongenetic factors in the development of hereditary SCA. DESIGN Quantitative assessm...

The understanding of prefrail and nonfrail older adults' postural control with and without increased environmental and cognitive stress is imperative to the development of targeted interventions to decrease fall risk within these populations. Thirty-eight individuals participated in this study. Postural control testing included the Sensory Organization Test (SOT) on a NeuroCom EquiTest. Cogniti...
