Strength and balance exercises form part of multifactorial programs to reduce the risk of falling and promote active ageing. The aim of this study was to evaluate the effect of a strength and balance exercise program, adapted from the traditional Otago Exercise Program (OTAGO) into a technological system. A non-randomized experimental study enrolled 34 participants (83.24 ± 6.89 years) from a daycare center in Portugal, who were distributed into an intervention group (IG; 18 participants) and a control group (CG; 16 participants). The IG underwent a "modified" OTAGO incorporated in a technological system using pressure and inertial sensors, feedback, and Exergames for 8 weeks, 3 times a week. The CG continued their regular activities. Outcome measures were evaluated at baseline and after 8 weeks of intervention. After the program, differences were observed between the groups in handgrip strength ( = 0.03), step test ( = 0.03), 4stage balance test "modified" ( < 0.001) and activities and participation profile related to mobility (PAPM) ( < 0.001). The IG showed positive results in the self-efficacy for exercise ( = 0.03), PAPM ( = 0.00) and all functional tests, except for timed up and go ( = 0.35). No significant changes were observed in the CG. The results support this intervention program as a good exercise solution to improve functional abilities, social participation, and self-efficacy, reducing the risk of falling.
力量和平衡练习是降低跌倒风险和促进积极老龄化的多因素方案的一部分。本研究旨在评估一项力量和平衡练习计划的效果，该计划改编自传统的奥塔哥运动计划（OTAGO）并融入了技术系统。一项非随机实验研究纳入了来自葡萄牙一家日托中心的 34 名参与者（83.24 ± 6.89 岁），他们被分为干预组（IG；18 名参与者）和对照组（CG；16 名参与者）。IG 接受了一项“改良”的 OTAGO，该计划融入了使用压力和惯性传感器、反馈和健身游戏的技术系统，每周进行 3 次，共 8 周。CG 继续进行常规活动。在基线和干预 8 周后评估了结果测量值。在该计划之后，组间在手握力（ = 0.03）、台阶测试（ = 0.03）、4 阶段平衡测试“改良版”（ < 0.001）和与移动性相关的活动和参与概况（PAPM）（ < 0.001）方面观察到差异。IG 在锻炼自我效能感（ = 0.03）、PAPM（ = 0.00）和所有功能测试方面表现出积极结果，除了计时上下（ = 0.35）外。CG 未观察到显著变化。结果支持该干预计划作为一种改善功能能力、社会参与和自我效能感、降低跌倒风险的良好锻炼解决方案。
