Fall accidents among older adults are a serious problem across the World. Nintendo Wii Fit (NWF) is a possible solution in future assessment of functions related to postual kontrol and impairment of balance. This study investigated if the NWF tests can discriminate between fallers and nonfallers. Twenty-six fallers (aged 65-90), and 33 nonfallers (aged 65-86) underwent clinical tests and NWF tests. Concurrent validity between the Short Physical Performance battery (SPPB), Functional Reach Test (FRT), and Single Leg Stance Test (SLST) and the NWF Stillness and Agility test was assessed. Nonfallers performed significantly better in the Stillness test than fallers (p<0.00**). In the Agility test nonfallers achived significantly more levels than fallers (p< 0.00**), but there was a significant effect of age. The NWF test were not able to discriminate between fallers and nonfallers, when looking at variance. The Agility test and the clinical tests showed moderate to strong correlations (0.62-0.70) with groups pooled. Within fallers moderate correlations (0.59-0.67) were found. Witin nonfallers low correlations (0.02-0.21) were found except FRT (0.39) . A model explored when an error of 10 trials of the Agility test is below 10% and 5%. Fallers needed four trials and nonfallers two, to achieve less than a 10% error, respectively, eight and six trials to achive less than 5% error. This model is uncertain, due to the affect of values averaged. The NWF was able to assess differences between fallers and nonfallers by the Stillness and agility test, why more challenging clinical test could help discriminating fallers from nonfallers and secure concurrent validity.
