“…In this work a modified Wii Balance Board™ (WBB) from Nintendo ® was used. This device was presented and has been validated in a previous work [ 16 ]. The Wii Balance Board™ (WBB) from Nintendo ® [ 17 ] is a suitable alternative to force platforms as stated by other studies [ 18 , 19 ] where the WBB has been validated, resulting in it performing comparably to laboratory-grade force platforms for static standing computerized posturography [ 18 ].…”

“…Furthermore, the WBB presents low inter-device variability [ 17 ]; even after years of use, these devices do not present significant alterations in their measurements; and the battery charge level does not affect the sensor data [ 19 ]. The only reported drawback for this device is the unstable sampling frequency, but in this work that problem was addressed by using a modified WBB to provide stable sampling frequency, as reported in [ 16 ].…”

“…The main contribution of this work, besides the methodology and algorithm presented, is the fact that the Modified Wii Balance Board platform (MWBB) provides a low-cost, portable, and easy-to-use system, ideal for non-laboratory environments [ 16 ], capable of estimating the probability of presenting a balance alteration in older adults and linking these measurements with fall risk.…”

Background The timely detection of fall risk or balance impairment in older adults is transcendental because, based on a reliable diagnosis, clinical actions can be taken to prevent accidents. This study presents a statistical model to estimate the fall risk from the center of pressure (CoP) data. Methods This study is a cross-sectional analysis from a cohort of community-dwelling older adults aged 60 and over living in Mexico City. CoP balance assessments were conducted in 414 older adults (72.2% females) with a mean age of 70.23 ± 6.68, using a modified and previously validated Wii Balance Board (MWBB) platform. From this information, 78 CoP indexes were calculated and analyzed. Multiple logistic regression models were fitted in order to estimate the relationship between balance alteration and the CoP indexes and other covariables. Results The CoP velocity index in the Antero-Posterior direction with open eyes (MVELAPOE) had the best value of area under the curve (AUC) to identify a balance alteration (0.714), and in the adjusted model, AUC was increased to 0.827. Older adults with their mean velocity higher than 14.24 mm/s had more risk of presenting a balance alteration than those below this value (OR (Odd Ratio) = 2.94, p<0.001, 95% C.I.(Confidence Interval) 1.68–5.15). Individuals with increased age and BMI were more likely to present a balance alteration (OR 1.17, p<0.001, 95% C.I. 1.12–1.23; OR 1.17, p<0.001, 95% C.I. 1.10–1.25). Contrary to what is reported in the literature, sex was not associated with presenting a balance alteration (p = 0.441, 95% C.I. 0.70–2.27). Significance The proposed model had a discriminatory capacity higher than those estimated by similar means and resources to this research and was implemented in an embedded standalone system which is low-cost, portable, and easy-to-use, ideal for non-laboratory environments. The authors recommend using this technology to support and complement the clinical tools to attend to the serious public health problem represented by falls in older adults.
