Positive correlation of postural balance evaluation by two different devices in community dwelling women

Abstract

OBJECTIVE: To establish the convergent validity or relationship of the Balance Master® as balance assessment device by comparing its performance results with those obtained from the AccuSway Plus® force plate. METHOD: Cross-sectional observational study, without intervention, of 126 postmenopausal women (60.3 ± 3.2 years; body mass index = 27.6 ± 4.7 kg/m 2). Two devices were used for the independent assessments of static balance: (a) Static postural balance assessment (posturography) was performed on a force platform (AccuSway Plus); (b) static evaluation was performed on the Balance Master® System. The variables studied in the two devices, were: (i) the Mean Velocity of the Center of Pressure Displacement in all directions (Vavg or Mean Firm), (ii) the Anteroposterior (Mean-Y) and (iii) the Mediolateral (Mean-X) Centers of Pressure Displacement. The Spearman correlation coefficient was calculated to measure the correlation of the variables of balance obtained with the two different devices. RESULTS: Significant correlations were obtained when the relationships between both variables were described by fitting multiple linear regression models. There was an association between the mean velocity of center of pressure displacement in both devices, with eyes open (r = 0.21) and eyes closed (r = 0.47). In the eyes open condition, Vavg increased, on average, 0.26 units, while Mean Firm increased 1.0 unit; in the Mean-Firm; in eyes closed condition, Vavg increased, on average, 1.27 units, while Mean-Firm increased by 1,0 unit. CONCLUSION: The devices investigated presented a significant correlation for the mean velocity calculated from the total displacement of the center of pressure in all directions.

Pharmacokinetics, Pharmacodynamics, Safety, and Tolerability of Mirogabalin When Coadministered With Lorazepam, Zolpidem, Tramadol, or Ethanol: Results From Drug‐Drug Interaction Studies in Healthy Subjects

“…We employed 2 different methods across our studies as available at each study center. In the lorazepam study, body sway was measured with use of a validated AccuSway PLUS Platform (Advanced Medical Technology Inc, Watertown, Massachusetts), which analyzes input from strain gauges located under the 4 quadrants of the platform to calculate the center of pressure (COP) . Extent of COP movement is directly related to the subject's ability to balance in a steady, upright position with eyes opened.…”

Efeitos da Kinesiotaping na Aplicação em Tornozelos Sobre o Controle Postural de Indivíduos Saudáveis

“…Considerando-se que o controle postural depende da manutenção do centro de massa dentro da base de apoio, e que esta atividade depende de uma organização complexa, desenvolvida com insumos sensoriais, o estímulo tátil oferecido pela KT parece oferecer um input tátil suficiente para promover a excitabilidade do sistema nervoso central e, assim, alterar o sistema de controle motor (ALONSO et al, 2014;BRECH;DUARTE;FREITAS, 2010). O uso das variáveis do COP avaliados pela plataforma força são considerados o padrão ouro para a avaliação do controle postural (BRECH;PAILLARD;NOÉ, 2015). Entre essa variáveis se deve considerar que a velocidade de deslocamento parece ser a que melhor reflete a eficiência do sistema de controle postural (PAILLARD; NOÉ, 2015).…”

Relationship of Force Platform With the Clinical Balance Evaluation Systems Test in Older Adults

“…However, the biomechanics industry creates more high cost sensitive equipments. 3 The NeuroCom Balance Master ® provides objective assessment of the sensory and voluntary motor control of balance with visual biofeedback, which enables objective assessment of performance in essential activities of daily living. Previous studies measuring the stabilometric parameters demonstrated that the equipment is reliable 4 and provides accurate measurements of the postural balance in different groups.…”
