Handgrip strength is a common, simple, and inexpensive method to measure muscle strength. On the other hand, the functional performance measurement involves a usual task which implies repeating elements between the individuals' interaction and the environment. This is fundamental for projecting their results to daily life situation.
To explore the relationship between grip strength and measures of functional performance of the upper limbs (ULs) in people over 18 years of age, and to determine the influence of sociodemographic and anthropometric variables on the relationship.
A cross-sectional study was conducted under the analytical empirical approach, using linear associations between handgrip strength and functional performance measurement tests (correspondence analysis).
Three hundred sixty-two male and female individuals between 18 and 91 years of age from 4 Colombian cities participated. The grip strength of both ULs measured with a digital dynamometry was associated with the Box and Block Test (BBT, manual dexterity), Nine-Hole Peg Test (NHPT, daily living tasks), and Jebsen-Taylor Hand Function Test (JJT, ability to grasp, pick up, and place). Multiple linear regression analyzes were performed to assess possible explanatory factors of a sociodemographic and anthropometric order.
A significant association was found between the grip strength of dominant and non-dominant ULs with all functional performance tests (ρ > 0.27 and p < .001), except for the writing and simulated feeding subtests of the JJT (ρ ≤ 0.16). An interactive effect of age was found in the relationship between grip strength and the 3 functional performance tests.
These results support the association between grip strength with the NHPT, JJT, and BBT measures and the interactive effect of age on the performance of all tests.
握力是一种常用、简单且经济的测量肌肉力量的方法。另一方面，功能表现测量涉及一项常规任务，这意味着在个体与环境的互动中存在重复元素。这对于将测量结果应用于日常生活情境至关重要。
探讨18岁以上人群的握力与上肢功能表现测量指标之间的关系，并确定社会人口统计学和人体测量学变量对这种关系的影响。
采用分析性实证方法进行横断面研究，利用握力与功能表现测量测试之间的线性关联（对应分析）。
来自哥伦比亚4个城市的362名年龄在18至91岁之间的男性和女性参与了研究。使用数字测力计测量的双侧上肢握力与箱块测试（BBT，手部灵巧性）、九孔插板测试（NHPT，日常生活任务）和杰布森-泰勒手部功能测试（JJT，抓握、拿起和放置能力）相关联。进行多元线性回归分析以评估社会人口统计学和人体测量学方面可能的解释因素。
除JJT的书写和模拟喂食子测试外（ρ≤0.16），优势侧和非优势侧上肢的握力与所有功能表现测试之间均存在显著关联（ρ>0.27且p<0.001）。在握力与3项功能表现测试之间的关系中发现了年龄的交互作用。
这些结果支持握力与NHPT、JJT和BBT测量指标之间的关联以及年龄对所有测试表现的交互作用。
