Low muscle strength is common and important in geriatric syndromes including frailty and sarcopenia. The epidemiology of grip strength of older people under long-term care facilities has been little explored.
The aim of this study was to assess handgrip strength of older women and men covered by institutional care and to analyse the associations between HGS and mobility, leg strength, flexibility, and postural balance.
This is a cross-sectional study carried out at care homes in southeastern Poland. After considering the inclusion criteria, 209 older people aged 65 to 85 were included in the study. Sociodemographic data were collected, and tests of muscular strength, mobility, flexibility, and postural balance were carried out by the use of the stabilometric platform CQ Stab 2P.
The average handgrip strength in the study group amounted to 19.8 kg, including 14.8 kg in women and 25.9 kg in men. Low grip strength was found in 67.83% women and 52.13% men in institutional care. A negative correlation between handgrip strength (HGS) and the Timed Up and Go (TUG) test was demonstrated, both with and without cognitive task and strength of lower limbs. Gait speed and dynamic balance were positively correlated with HGS. A negative correlation was found between the total length of the centre of pressure (COP) path, the length of the COP path in the lateral-medial direction, and the sway area delimited by the COP and HGS for the dominant hand. Speaking of women, gait speed was most strongly associated with HGS, while among men, it was upper limb flexibility.
Regardless of gender, HGS is associated with mobility, strength of the lower limbs, and dynamic balance. By means of simple tools, early diagnosis will facilitate the planning of appropriate interventions in order to prevent disability and mortality in long-term care facilities.
肌肉力量弱是老年人常见且重要的问题，包括衰弱和肌肉减少症。长期护理机构老年人握力的流行病学研究甚少。
本研究旨在评估机构护理老年人的手掌握力，并分析握力与移动能力、下肢力量、灵活性和姿势平衡之间的关系。
这是一项在波兰东南部养老院进行的横断面研究。在考虑纳入标准后，共有 209 名 65 至 85 岁的老年人纳入研究。收集了社会人口统计学数据，并使用 CQ Stab 2P 稳定平台进行了肌肉力量、移动能力、灵活性和姿势平衡测试。
研究组的平均握力为 19.8 公斤，其中女性为 14.8 公斤，男性为 25.9 公斤。在机构护理中，女性握力低的比例为 67.83%，男性为 52.13%。在有或没有认知任务和下肢力量的情况下，握力（HGS）与计时起立行走（TUG）测试之间均呈负相关。步态速度和动态平衡与 HGS 呈正相关。手优势侧的总中心点（COP）轨迹长度、COP 轨迹在前后方向上的长度以及由 COP 界定的摆动面积与 HGS 呈负相关。对于女性来说，步态速度与 HGS 相关性最强，而对于男性来说，是上肢灵活性。
无论性别如何，HGS 都与移动能力、下肢力量和动态平衡有关。通过使用简单的工具，早期诊断将有助于规划适当的干预措施，以防止长期护理机构的残疾和死亡。
