To determine the safety and feasibility of using Nintendo Wii Fit exergames to improve balance in older adults.
Seven older adults aged 84 (5) years with impaired balance (Berg Balance Scale [BBS] score < 52 points) were recruited from 4 continuing care retirement communities to participate in a single group pre- and postevaluation of Wii Fit exergames. Participants received individualized instructions (at least 5 home visits) on playing 4 exergames (basic step, soccer heading, ski slalom, and table tilt) and were asked to play these games in their homes at least 30 minutes 3 times per week for 3 months and received weekly telephone follow-up. They also completed a paper log of their exergame play and rated their enjoyment immediately after each session. Participants completed the BBS, 4-Meter Timed Walk test, and the Physical Activity Enjoyment Scale at baseline and 3 months. Semistructured interviews were conducted at the 3-month evaluation.
Participants safely and independently played a mean of 50 sessions, median session duration of 31 minutes. Two of the games were modified to ensure participants' safety. Participants rated high enjoyment immediately after exergame play and expressed experiencing improved balance with daily activities and desire to play exergames with their grandchildren. Berg Balance Scores increased from 49 (2.1) to 53 (1.8) points (P = .017). Walking speed increased from 1.04 (0.2) to 1.33 (0.84) m/s (P = .018).
Use of Wii Fit for limited supervised balance training in the home was safe and feasible for a selected sample of older adults. Further research is needed to determine clinical efficacy in a larger, diverse sample and ascertain whether Wii Fit exergames can be integrated into physical therapy practice to promote health in older adults.
确定使用任天堂 Wii Fit 运动游戏来改善老年人平衡能力的安全性和可行性。
从 4 个持续护理退休社区招募了 7 名年龄为 84（5）岁、平衡能力受损（Berg 平衡量表[BBS]评分<52 分）的老年人参与 Wii Fit 运动游戏的单组前后评估。参与者接受了个性化的指导（至少 5 次家访），学习玩 4 种运动游戏（基本踏步、足球头球、滑雪障碍赛和桌面倾斜），并被要求在 3 个月内每周至少在家中玩 3 次，每次 30 分钟，并接受每周电话随访。他们还填写了运动游戏记录，并在每次游戏后立即对其趣味性进行评分。参与者在基线和 3 个月时完成了 BBS、4 米定时步行测试和身体活动享受量表。在 3 个月的评估中进行了半结构化访谈。
参与者安全且独立地进行了平均 50 次游戏，每次游戏的中位数时长为 31 分钟。为确保参与者的安全，对其中 2 个游戏进行了修改。参与者在游戏后立即对其趣味性给予高度评价，并表示日常活动中平衡能力有所提高，希望与孙子孙女一起玩运动游戏。Berg 平衡量表评分从 49（2.1）增加到 53（1.8）分（P=0.017）。行走速度从 1.04（0.2）增加到 1.33（0.84）米/秒（P=0.018）。
在家中使用 Wii Fit 进行有限监督的平衡训练对选定的老年人群体是安全且可行的。需要进一步的研究来确定更大、更多样化的样本中的临床疗效，并确定 Wii Fit 运动游戏是否可以整合到物理治疗实践中，以促进老年人的健康。
