PURPOSE To evaluate the magnitude of subclinical balance dysfunction in adult epilepsy patients and to assess the relative contribution of different variables to balance impairment. METHODS Balance performance was evaluated by computerized dynamic platform posturography (CDPP) in 25 adult patients following a generalized tonic-clonic seizure (GTCS) and in 11 healthy subjects. RESULTS The GT...

INTRODUCTION AND OBJECTIVE Posturography allows evaluating postural control. This study showed the posturographic parameters that were useful for assessing the functional ability to maintain balance in our sample of vestibular patients. MATERIAL AND METHODS Of a total of 89 patients, 59 were healthy subjects and 30 had a peripheral vestibular disorder. The subjects were studied using the post...

OBJECTIVE To determine if variations in common treatments for benign paroxysmal positional vertigo (BPPV) affected efficacy. STUDY DESIGN Prospective, pseudo-randomized study. SETTING Outpatient practice in a tertiary care facility. SUBJECTS AND METHODS Patients (n = 118) with unilateral BPPV of the posterior canal, including 13 patients with BPPV of the lateral canal, were tested at a te...

Functional near-infrared spectroscopy (fNIRS) is a non-invasive brain imaging method that uses light to record regional changes in cerebral blood flow in the cortex during activation. fNIRS uses portable wearable sensors to allow measurements of brain activation during tasking. In this study, fNIRS was used to investigate how the brain processes information from multiple sensory modalities duri...

The objective of this study was to evaluate relationships between subjective and objective measures of balance in multiple sclerosis (MS). In 54 subjects with MS, balance was measured objectively with the Sensory Organization Test (SOT) using dynamic posturography and subjectively with the Activities-specific Balance Confidence (ABC) Scale and the Falls Efficacy Scale-International (FES-I). MS-...

OBJECTIVES/HYPOTHESIS To determine the degree to which balance is impaired by fatigue in postcall medical residents and to assess the validity of posturography in quantifying that impairment. STUDY DESIGN Prospective study. METHODS Medical residents underwent the following tests before and immediately after overnight call: 1) computerized dynamic posturography (CDP) using the Equitest force...

INTRODUCTION The sensory organization test and the limits of stability are the gold standard for dynamic posturography. It is postulated that these measurements vary depending on age, activity of the subject and musculoskeletal system, emotional condition or other factors. The aim of this study was to determine the influence of gender on the above-mentioned analyses. MATERIAL AND METHODS 70 h...

Van Nes rotationplasty is a treatment option for individuals with congenital proximal focal femoral deficiency (PFFD), in which the extremity is surgically rotated to utilize the ankle and foot as a functional knee joint in a prosthesis. This case control study was done to determine the long-term function and quality of life (QOL) outcomes of these individuals. Twelve prosthetic participants (P...

Dear Editor: I would like to congratulate the authors for the article regarding the calculation of the so-called ellipse area [1]. As the authors indicated, the algorithms employed to calculate the area of the 95% prediction ellipse using the chi-square or the Rayleigh distribution are in fact only exact when the number of samples of the bivariate variable tends to infinite (when each univariat...
