Effectiveness of Tai Chi and Nintendo Wii Fit Plus For The Improvement of Balance and Reduction of Falls In Older Adults: A Literature Review
Introduction: The aim of this study was to perform a literature review and to identify the effectiveness of tai chi and Nintendo Wii Fit Plus balance board exercises on balance and incidence of falls in older adults. Methods: The literature review was performed through databases ScienceDirect, Scopus, PubMed, PEDro and Cochrane Library. The studies met the following inclusion criteria: participants’ age ≥ 60 years, MoCa test > 23, randomised clinical trials, age of study < 15 years, journal impact factor > 0. The following keywords were used: "tai chi"/"tai ji chuan"/"tai ji quan", "nintendo wii fit plus", "elderly", "older adults", "balance", "falls" and "prevention." Results: Based on the given criteria and keywords, a total of 186 articles were found, of which 23 full papers were included in the review (11 for tai chi, 12 for Wii Fit Plus). Based on the differences in the improvement in the selected measurement tests, it was found a greater positive effect of tai chi exercise, which depends on a lower initial level of development of participant’s balance, which further influenced the final improvement in balance and the incidence of falls. Discussion: The qualitative literature review shows that tai chi exercise seems more effective at improving balance and reduction of falls in older adults. Further quantitative analysis of collected data will show whether greater short-term and long-term effectiveness of tai chi exercise is also statistically significant.
