The present study was aimed at analyzing correlation between strength of lower body extremities and postural stability in function of age. A pool of 180 women divided into 6 age groups (65-69, 70-74, 75-79, 80-84, 85-89 and 90-94 years) was examined. They all were informed-consent participants. The results suggest that age is negatively correlated with lower body strength and positively correlated with decrease of postural balance. There is also an exponential correlation between the strength of lower body part and postural balance. The conclusion was derived that postural stability is at least partially controlled by the strength of lower body. The age of 75 in women population seems to be a threshold above which the neurodegenerative and muscle degeneration processes are responsible for significant increase of risk of fall.
本研究旨在分析下肢力量与姿势稳定性之间随年龄变化的相关性。研究对180名女性进行了检查，她们被分为6个年龄组（65 - 69岁、70 - 74岁、75 - 79岁、80 - 84岁、85 - 89岁和90 - 94岁）。她们均为签署知情同意书的参与者。结果表明，年龄与下肢力量呈负相关，与姿势平衡的下降呈正相关。下肢力量与姿势平衡之间也存在指数相关性。由此得出结论，姿势稳定性至少部分受下肢力量控制。在女性人群中，75岁似乎是一个阈值，超过这个年龄，神经退行性变和肌肉退化过程会导致跌倒风险显著增加。
