Abstract:
During the last 10 years, computerized dynamic posturography has yielded various patterns of sway on the sensory organization test and the motor control test that have been associated with a variety of organic balance disorders. Some aspects of performance during computerized dynamic posturography, however, are under conscious control. Voluntary movements not indicative of physiologic response to balance system stimulation can also affect computerized dynamic posturography results. Quantification of nonorganic or “aphysiologic” response patterns in normal subjects, patients, and suspected malingerers is crucial to justify use of computerized dynamic posturography for identification of physiologically inconsistent results. For this purpose the computerized dynamic posturography records of 122 normal subjects, 347 patients with known or suspected balance disorders, and 72 subjects instructed to feign a balance disturbance were critically evaluated by use of seven measurement criteria, which were postulated as indicating aphysiologic sway. Each criterion was scored with a standard calculation of the raw data in a random, blinded fashion. The results of this multicenter study show that three of the seven criteria are significantly different in the suspected “malingerer” group when compared with either the normal or patient group. The relative strength of each criterion in discerning organic from nonorganic sway provides the examiner with a measure of reliability during platform posture testing. This study demonstrates that computerized dynamic posturography can accurately identify and document nonorganic sway patterns during routine assessment of posture control.

Abstract:
Background Low-dose combined spinal-epidural analgesia in labor has proved popular with women because lower-limb motor power is preserved, allowing ambulation. However, there has been debate about the safety of allowing women to walk following low-dose regional analgesia because of somatosensory impairment. The authors undertook a prospective controlled observational study using computerized dynamic posturography to examine balance function in pregnant women after combined spinal-epidural analgesia. Methods The authors performed posturographic testing on 44 women in labor after institution of regional analgesia and compared them with a control group of 44 pregnant women. A separate group of six women were tested both before and after combined spinal-epidural analgesia. Results Neurologic examination after regional analgesia showed two parturients (4%) to have motor weakness (excluded from posturography). Four women (9%) had clinical dorsal column sensory loss; these women all completed posturography. The spinal-epidural analgesia group showed a small, statistically significant reduction in one of six posturographic sensory-organization tests; however, this difference was functionally minor. There were no other differences in posturography between the control and spinal-epidural groups. Similar results were found in the paired study, in which there was minimal change in balance function after spinal-epidural analgesia. Conclusions This is the first study to objectively examine the effect of spinal-epidural analgesia on balance function. Using computerized dynamic posturography, the authors were unable to find any functional impairment of balance function after spinal-epidural ambulatory analgesia in women in labor who had no clinical evidence of motor block.

Abstract:
Balance is the ability to maintain an individual’s centre of mass over his or her base of support while standing. Ballet dancers have better balance than non-dancer control groups as they presented with better sensory-motor integrative skills when required to maintain a given posture for a longer period. To evaluate functional balance abilities, assessing individuals with above average balance abilities may provide valuable information about function. The balance of trained ballet dancers (N1) was investigated by comparing Sensory Organisaiton Test (SOT), Motor Control Test (MCT) and Limits of Stability (LOS) test results to matched non-trained individuals (N2). A quasi-experimental and two group design was used. Ten matched trained ballet dancers (N1) and 10 untrained individuals were included in the study. Trained ballet dancers (N1) had an average of 16.6 (± 4.24) years of experience, while non-trained individuals (N2) had none. No significant dufferences in demographic data was present between groups. Both groups reflected good overall balance and similar sensory organization. No differences in reflex latencies and weight symmetry of the left or right leg was present. Trained ballet dancers (N1) reflected higher response strength for medium forward translations (p.05) with the left leg, indicating poorer amplitude scaling in response to platform translations than those of non-trained individuals (N2). In non-trained individuals (N2), there was less variation in the response strength between legs. Research indicated that stretch reflex amplitude was attenuated as load stability was reduced. Co-contraction was also heightened as stability was reduced, but not enough to oppose the induced instability, probably due to feed-forward strategies instead of rapid involuntary feedback. Trained ballet dancers (N1) were able to extend further out of their Centre of Pressure (COP) than non-trained individual (N2) during forward (p<.05) and right forward (p<.05) movements. It was concluded that that for forward and right forward movements, ballet dancers used the feedback they received during the movements better than non-trained individuals (N2), resulting in a better awareness of where to go in space and how to reach that position after a subsequent attempt. This difference may be as a result of continuous training. Ballet training exercises can be used to rehabilitate individuals with impaired limits of stability. Further studies should be done on exactly which ballet training exercise results in increased limits of stability.

Abstract:
Sensory Organization Test (SOT) quantifies contributions of three sensory systems to postural stability and identifies fall risk. This study evaluated reliability and validity of SOT on a newly available computerized dynamic posturography system (Bertec) compared to the gold standard (NeuroCom). Forty-three adults with normal vestibular function completed testing on both systems over two sessions. Bertec SOT is valid and reliable in this population, but differences in composite scores between Bertec and NeuroCom suggest the systems are not interchangeable.

Abstract:
Postural instability is one of the hallmarks of Parkinson's disease (PD), currently evaluated using several subjective tools. However, the nature and degree of the resulting balance deficit is not well specified by these tools. Computerized dynamic posturography (CDP) provides an objective assessment by isolating and quantifying sensory and motor contributions to balance control. The purpose of this study was to compare balance in individuals with PD to a control group using CDP (NeuroCom Smart Balance Master® system). Testing took place at the Southeast Parkinson's disease Research Education and Clinical Center (PADRECC), an interdisciplinary center of excellence for people with PD within a Veterans Affairs Medical Center. The 51 PD patients (mean age = 72.18 ± 6.98 years;) were compared to 55 age-matched controls supplied by the CDP manufacturer. Subjects were assessed with three test scales defined by the Smart Balance Master® system: Sensory Organization Test (SOT), Adaptation Test (ADT), and Limits of Stability Test (LOS). All PD population CDP scores were significantly different (a=0.05) than those of a healthy population, except for the SOT Somatosensory subscale (p=0.28), LOS Directional Control subscale (p=0.08), ADT Toes Up subscale (p=0.16) and ADT Toes Down subscale (p=0.23). The Smart Balance Master® system's LOS Movement Velocity, Endpoint Excursion, Maximum Excursion, and Reaction Time subscores and the SOT Composite, Visual, and Vestibular subscores uniquely describe the varying symptoms of the disease. These disease specific abnormalities may provide insight into focused treatment intervention strategies.

INTRODUÇÃO: O consumo mundial de açúcar triplicou nos últimos 50 anos e a sua ingesta abusiva é responsável pela resistência periférica à insulina, que origina a síndrome metabólica - obesidade, diabetes melito, hipertensão arterial e doenças coronarianas . Motivados pelo elevado número de pacientes que nos procuram com queixas vestibulares associadas aos distúrbios de metabolismo da glicose (DMG) resolvemos avaliar de forma objetiva, a influência dos DMG nas disfunções labirínticas e o efeito da dieta restritiva de carboidratos como forma de tratamento. OBJETIVO: Observar o impacto da dieta fracionada e restritiva de carboidratos na qualidade de vida dos pacientes portadores de distúrbios do equilíbrio corporal e DMG por meio da posturografia dinâmica computadorizada (PDC), do disability index (DI) e da escala análogo-visual (EAV). CASUÍSTICA E METODOLOGIA: Este estudo foi desenhado como um ensaio clínico prospectivo controlado randomizado realizado no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. A amostra foi constituída de 51 pacientes divididos em dois grupos: Grupo Dieta (GD): indivíduos tratados com comprimidos de placebo e dieta fracionada com restrição de glicose, Grupo Controle (GC): receberam apenas placebo. Os pacientes realizaram PDC, DI e EAV no primeiro e trigésimo dias do estudo. RESULTADOS: A amostra mostrou-se homogêna quando comparados os grupos e observou-se melhora, estatísticamente comprovada nas condições posturográficas avaliadas quando comparados GD e GC. Observou-se ainda melhora clínica do GD na análise da EAV. CONCLUSÃO: A dieta fracionada e restritiva de carboidratos mostrou-se eficaz no tratamento da nossa amostra de pacientes portadores de disfunções vestibulares associadas a DMG.
INTRODUCTION: World sugar consumption has tripled in the last 50 years and its abusive ingestion is responsible for peripheral insulin resistance, which leads to metabolic syndrome - obesity, diabetes mellitus, hypertension and coronary heart disease. Because of the high number of patients with vestibular complaints and with glucose metabolism disorders (GMD) we decided to objectively evaluate the effect of glucose restrictive and fractionated diet as a option of treatment in these patients. OBJECTIVE: To evaluate the impact of the glucose restrictive and fractionated diet on the Computerized Dynamic Posturography (CDP), disability index (DI) and the visual analogue scale (VAS) in patients with balance disorders and disorders of glucose metabolism. SAMPLES AND METHODOLOGY: Randomized controlled trial. Sample of 51 patients divided into two groups: Diet Group (DG) treated with placebo pills and glucose restrictive and fractionated diet and Control Group (CG) with only placebo. The individuals performed CDP, DI and VAS at first and thirtieth days of study. RESULTS: The sample groups were homogeneous before the study. There were significant improvement of DG on CDP conditions 4, 5, 6 and composite score. There was, also, significant improvement of VAS analysis on DG after intervention. CONCLUSION: The glucose restrictive and fractionated diet was effective in the treatment of patients with vestibular dysfunction associated with glucose metabolism disorders
