Fall is a frequent reason to reduced level of function, and causesboth the individual and the public society large expenses (1,2). One of the largestrisk factors in relation to fall is balance deficits (3). Balance training is an importantpart of a multifactorial intervention to prevent falls (3). Nintendo Wii Fit (NWF) couldbe a new device for balance training.The purpose of this study was to measure the outcome effect of NWF as a balancetraining device for elderly community dwellers.RESULTSThe median improved from baseline to the 4 week measurement in all parameters inboth EG and CG (figure 1).The EG had a score (median (range)) of 15,5 (0-70) at baseline and 40 (15-69) after 4weeks, while the CG had a score of 12 (0-68) at baseline and 36 (0-54) after 4 weeks.The EG had a time of 41,29s (17,93-99,20) at baseline and 27,76s (13,58-40,64) after 4weeks, while the CG had a time of 62,69s (12,48-163,40) at baseline and 31,32 (15,80-95,87) after 4 weeks.The EG had a distance of 3075mm (764-8050) at baseline and 2027mm (1064-3331) after4 weeks, while the CG had a distance of 3236mm (1249-16404) at baseline and 1846mm(1298-5233) after 4 weeks.The EG had a TUG time of 9,4s (4,9-19,4) at baseline and 8,0s (4,5-17,0) after 4 weeks,while the CG had a score of 11,6s (5,7-22,1) at baseline and 9,6s (5,4-20,8) after 4 weeks.The EG showed statistically significant improvement in time in Metitur dynamicmeasurement (p = 0,043). Neither when comparing changes from baseline to the 4 weekmeasurement nor when comparing EG and CG other statistically significant differenceswere found.20 subjects (aged 71-89) were included (11 men). The subjects were blockrandomized into 2 groups by gender (exercise group=EG, control group=CG), n=10(EG=6 men, CG=5 men). There were 4 drop-outs during the study period (EG=3,CG=1).The EG participated in training sessions with NWF 20 min. 2 times/week for a 4week period, while the CG sustained their normal activity level.The subjects were tested at baseline and after 4 weeks. The outcome measurementswere Metitur force platform dynamic measurements (score, time and distance) andTimed Up and Go (TUG).The data were not normally distributed. Wilcoxon signed-rank test were used toevaluate the changes from baseline to the 4 week measurement while Mann-Whitney U test were used to compare the changes in the two groups in the sameperiod.MATERIALS AND METHODSPrevious studies have shown that visual based feedback training improves balance (4,5).Sihvonen et al. found significant improvements in time and distance after 4-weeks ofvisual feedback training (5). The present study found significant improvements in time inelderly community dwellers after 4-weeks of training on NWF. This could indicate that thesubjects developed a more confident postural control moving near the limits of stability(5). An improved sensory integration could be one of the main reasons to this change.Neither the clinical test (TUG) nor the rest of the dynamic measurements (score anddistance) showed any significant changes after the 4-weeks training, and there were nosignificant differences between EG and CG in any of the parameters. This do not supportthe previous study indicating improvements in distance and clinical test after 4-weeks ofvisual feedback training (5).CONCLUSIONBased on the results of this study it is not possible to determine whether Nintendo WiiFit as a balance training device improves the balance in elderly community dwellers.Further research is required to establish evidence of Nintendo Wii Fit as a device forbalance training in elderly community dwellers.1.
