Purpose: This study evaluated the feasibility of using Nintendo Wii games for improving cognition, balance, function in patients with dementia. Methods: A total 30 dementia patients were randomly assigned into the experimental group(n=15) and control group(n=15). All subjects performed a general therapeutic exercise, and 30-minute sessions of the table tennis and fencing game of Nintendo Wii were conducted with experimental group 3 times a week for 8 weeks. The intervention effects were measured by using MMSE-K, BBS, and FIM. The results were analyzed by using repeated measure ANOVA. Results: The MMSE-K and BBS scores showed significant differences. A significant interaction was observed between the experimental group and the control group in MMSE-K. The final MMSE-K and BBS scores for the experimental group were significantly higher than those for the control group. However, there was no difference in the FIM scores. Conclusion: We suggest that Nintendo Wii games are effective in cognㅇition and balance improvement in dementia patients. Future research on a variety of programs in needed.

This study performed a virtual reality exercise program for self-back pain control of industrial workers with chronic back pain and analysed their physical function and health-related quality of life relating to industrial chronic back pain. The subjects of the study were thirty chronic back pain patients working for K company and were divided into Nintendo Wii Sports Group made of 15 subjects and Physical Therapy Group made of 15. As variables for physical functions, back strength, flexibility, balance and pain were measured and for the health-related quality of life, SF-36 of each group was measured before and after the exercise program. To compare differences before and after the program, a paired t-test was used and to compare differences between both groups, an independent samples t-test was used. As a result of the test, it was discovered that balance and pain of the both groups were improved statistically significantly. Physical functions of the Nintendo Wii Sports Group were improved statistically significantly in comparison with those of the Physical Therapy Group. The health-related quality of life was improved statistically significantly only for the Nintendo Wii Sports Group. In conclusion, it is suggested that as the virtual reality exercise program had a positive influence on chronic back pain of industrial workers, it should be considered as a home exercise program for back pain control.

PURPOSE: A good, valid, and feasible tool for evaluating sit to stand (STS) is needed to help clinicians quantify the STS ability of stroke patients and people with balance disorders. The purpose of this study was to evaluate the concurrent validity of the Nintendo Wii Balance Board (WBB) and a force plate during STS and gait. METHODS: Seventeen healthy adults performed five trials of STS and gait on the WBB placed on the force plate. The force plate and the WBB were compared in regard to center of pressure (COP) and ground reaction force (GRF) data that were collected simultaneously. The variables used for analysis were time (s), integral summation (%), COP path length (mm), COP x range, and COP y range, all of which were measured for both tasks. Counter (%), peak (%), and rebound (%) were analyzed for STS, and $1^{st}$ peak (%), min peak (%), and 2nd peak (%) were analyzed for gait. The concurrent validity was analyzed using an intraclass correlation coefficient (ICC) and a standard error of measurement (SEM) with a 95% confidence interval. RESULTS: The concurrent validity of the WBB for STS ranged from fair to good (ICC=.701~.994, SEM=.029~3.815). The concurrent validity for gait was good (ICC=.869 ~.989, SEM=.007~2.052) aside from path length and x and y ranges of COP (ICC=-.150~.371, SEM=3.635~4.142). CONCLUSION: The GRF of the WBB has a good validity for STS and gait analysis. The WBB is remarkably portable, easy to use, and convenient for clinically assessing STS and gait.

The success of Nintendo's Wii has changed the paradigm of console game. Existing games and consoles set up the game-playing system of complicated commands, narratives, and significantly advanced the degree of difficulty by the device's excellent capacity and the superiority of graphic in order to draw so called "Game Manias", while Nintendo established the easy game-playing system for not only game manias but women and elderly people. Such an innovation has carried out the most important role for Nintendo to dominate the market all over the world by 47.4% market share of consoles. In addition, it provided the users with unique interaction and emotional experience. In this study, we analyze the case above in terms of product design strategy, particularly emotional design strategy between Nintendo & Sony.

Sleep deprivation may cause accidents, and it has deteriorating effects on health. A measurement of postural steadiness by a portable and affordable Nintendo Wii Fit balance board can be used to quantify a person's alertness. At work, people are under the influence of their environment-often other peopl-dthat may affect their alertness. This work investigates whether sleep deprivation among people is "contagious," as quantified by sway measures. We measured 21 volunteers' postural steadiness while alert and sleep deprived. During the measurements, a screen placed in front of the participants showed a footage of either alert or sleep-deprived faces. We found a significant difference between the day time and night time steadiness, but found no effect resulting from watching footage of sleep-deprived people. This finding shows that a posturographic sleepiness tester quantifies physiological sleep deprivation, and is insensitive to the influence of social factors.

We investigated the effects of a Virtual reality(VR) program on the proprioception and instability of functional ankle instability(FAI) patients. Among the 20s old individuals who lived in Republic of Korea; 20 people were selected through a public participation process. The 20 participants were then randomly divided into two groups, one of strength exercise(n=10) and one of balance exercise(n=10). Of the patients who had experienced an ankle sprain in the past and currently felt ankle instability, those who recorded 24 points or less on the Cumberland ankle instability tool(CAIT) were determined to have FAI. We selected the strength exercise and balance exercise in the Nintendo Wii Fit Plus as a VR program. The subjects used the program on the Wii Balance Board three times per week for 20 minutes and total 10-minute warm-up and down for four weeks. Proprioception and CAIT of the balance exercise group were improved significantly after the exercise compared to before the exercise(p<.05). Authors recommend that the balance exercise in the VR program be used as an aid for physical therapeutic intervention.
