- Positive correlation of postural balance evaluation by two different devices in community dwelling women(2016) BRECH, Guilherme Carlos; LUNA, Natália Mariana Silva; ALONSO, Angélica Castilho; GREVE, Júlia María D'AndréaOBJECTIVE: 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/m2). 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.
