Handgrip dynamometers are used to assess handgrip strength (HGS), and low HGS is linked to poor cognitive function. Although HGS is a reliable measure of muscle function, it is only measuring maximal grip force. Other aspects of muscle function such as force control, fatigability, and steadiness are unaccounted for in current HGS protocols. This pilot study sought to determine the role of maximal HGS, submaximal HGS force control, HGS fatigability, and HGS neuromuscular steadiness on cognitive function in older adults. Our findings indicate that these additional HGS measurements could factor into detecting poorer cognitive functioning, while also evolving HGS protocols.
握力计用于评估握力（HGS），而低握力与认知功能差有关。尽管握力是肌肉功能的可靠指标，但它仅测量最大握力。肌肉功能的其他方面，如力量控制、疲劳性和稳定性，在当前的握力测试方案中并未得到考虑。这项初步研究旨在确定最大握力、次最大握力的力量控制、握力疲劳性和握力神经肌肉稳定性在老年人认知功能中的作用。我们的研究结果表明，这些额外的握力测量可能有助于检测较差的认知功能，同时也会改进握力测试方案。
