The objective of the study was to examine the association between handgrip strength (HGS), knee flexion and extension strength, and static and dynamic balance in older women. One hundred and ten women with a mean age of 67.4±5.9 years were assessed for dynamic postural balance using the Time Up & Go Test (TUG) with and without cognitive tasks. Semi-static balance was assessed by means of a force platform; knee flexor and extensor muscle strength was calculated using an isokinetic dynamometer; and HGS using a hand held dynamometer. Weaker HGS was significantly correlated with worse performance in dynamic postural balance, as well as performance with TUG with and without cognitive tasks; however, there was no correlation between HGS and static balance. There was a moderate positive correlation between knee flexion/extension strength and HGS. This suggests that HGS could be used as a proxy indicator of overall strength capacity for clinical screening among older women.
本研究旨在探讨老年人握力(HGS)、膝关节屈伸力量以及静态和动态平衡之间的关系。对 110 名平均年龄为 67.4±5.9 岁的女性进行了动态姿势平衡测试,使用带有和不带有认知任务的“起立-行走测试”(TUG)进行测试。半静态平衡通过测力平台进行评估;使用等速测力计计算膝关节屈肌和伸肌力量;使用手持测力计测量握力。较弱的握力与动态姿势平衡以及 TUG 测试(无论是否有认知任务)的表现较差显著相关;然而,握力与静态平衡之间没有相关性。膝关节屈伸力量与握力之间存在中度正相关。这表明握力可以作为临床筛查老年女性整体力量能力的替代指标。
