This study was conducted with older adults living in a long-stay institution in the city of Foz do Iguacu, Parana, Brazil with the objective of assessing the influence of muscle strength loss in the risk of falls. The sample consisted of 65 elderly who walk without the aid of support for locomotion, 37 women and 28 men, aged between 67 and 80 years. The risk of falls was assessed through the TUG test. To determine the handgrip strength, a hand dynamometer model Jamar ( was used, which provides the result in kg / force (kgf), being held only with the dominant hand. The results showed that in the last 12 months, only 32% of the elderly surveyed had no fall and the average handgrip strength was 24.32 ( 11.22 kgf; 40% had one fall and the average handgrip strength was 23.82 ( 10.18 kgf; 8% had two falls and the average handgrip strength was 19.48 ( 8.21 kgf and 20% had more than one fall and the average handgrip strength of 18.13 ( 7.33 Kgf., indicating that the force levels are statistically lower among elderly at high risk of falls (p> 0.05). It was concluded that the lower the force level, the greater the likelihood of falls. Thus, it is important to stress that due to the loss of muscle strength, all ergonomic hazards and architectural barriers must be removed so that older adults can perform their tasks more easily, with comfort and safety.
本研究针对居住在巴西巴拉那州伊瓜苏市一家长期护理机构的老年人开展，目的是评估肌肉力量丧失对跌倒风险的影响。样本包括65名无需借助辅助进行行走的老年人，其中37名女性和28名男性，年龄在67至80岁之间。通过定时起立行走测试（TUG测试）评估跌倒风险。为测定握力，使用了Jamar型握力计，仅用优势手握持，其结果以千克/力（kgf）表示。结果显示，在过去12个月中，接受调查的老年人中只有32%没有跌倒，平均握力为24.32（±11.22）kgf；40%的人跌倒过一次，平均握力为23.82（±10.18）kgf；8%的人跌倒过两次，平均握力为19.48（±8.21）kgf；20%的人跌倒过不止一次，平均握力为18.13（±7.33）kgf，这表明跌倒高风险老年人的力量水平在统计学上较低（p>0.05）。研究得出结论，力量水平越低，跌倒的可能性越大。因此，必须强调，由于肌肉力量丧失，所有人体工程学危害和建筑障碍都必须消除，以便老年人能够更轻松、舒适且安全地完成任务。
