Falls in the elderly are common with consecutive high mortality and morbidity. Recent consecutive data focus on identification and therapy of intrinsic risk factors. Sarcopenia, imbalance and gait disorders represent the major risk factors. Sarcopenia is caused by a disequilibrium of protein synthesis and breakdown, probably in consequence of age-related changes in protein metabolism. Protein supplements in combination with strength training shows the best benefit. Disorders in balance and gait are caused by age-related or pathologic changes in a complex regulation system of gait. The individual fall risk correlates with the gait variability and even increases with bad dual task performance. Activities with high requirements of attention and body awareness are the most effective prevention for falls in the elderly (-50%).
老年人跌倒很常见,随之而来的是高死亡率和高发病率。最近的一系列数据聚焦于内在风险因素的识别与治疗。肌肉减少症、平衡失调和步态障碍是主要风险因素。肌肉减少症是由蛋白质合成与分解的失衡引起的,这可能是蛋白质代谢中与年龄相关变化的结果。蛋白质补充剂与力量训练相结合显示出最佳效果。平衡和步态障碍是由步态复杂调节系统中与年龄相关或病理性变化引起的。个体跌倒风险与步态变异性相关,甚至在双重任务表现不佳时会增加。对注意力和身体感知要求较高的活动是预防老年人跌倒最有效的方法(降低50%)。
