背景：有关体力能力的数据对于设计安全和可用的产品是必不可少的，并在广泛的临床环境中有用，特别是在治疗影响手功能的疾病时。本研究的目的是测定伊朗健康儿童和青年人群的最大侧向捏力、关键捏力、尖端到尖端捏力和三颌力用力。用标准坐姿的优势手和非优势手使用B&L夹具进行测量。每种情况下每次力量测量重复两次，并在随后的分析中使用两次实验的平均值。结果：在年龄、性别和手优势方面，握力数据存在显著差异。女性的侧向握力、按键握力、顶尖握力和三颌握力分别为男性的68.4%、68.8%、78.8%和81.8%。在侧向握力、按键握力、顶尖握力和三颌握力方面，非优势手的力量消耗分别比优势手的6.4%、5.2%、6.6%和5.1%低。结论：这些发现可以用来填补伊朗人群力量数据的空白。
Background: Data on the physical strength capabilities are essential for designing safe and usable products and are useful in a wide range of clinical settings especially during treatment of disease affecting the function of the hand. The purpose of this study was to determine peak lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions in a healthy Iranian children and young adult population.Methods: The study was conducted among 511 participants (242 males and 269 females) aged 7-30 years. Measurements were carried out with both dominant and non-dominant hands in standard sitting posture using a B&L pinch gauge. Two repetitions of each strength measurement were recorded for each condition and the average value of the two trials was used in the subsequent analysis.Results: The results showed significant differences in the pinch strength data in terms of the age, gender and hand dominance. The lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions by females were 68.4%, 68.8%, 78.8% and 81.8% of those exerted by males, respectively. Strength exertions with the non-dominant hand were 6.4%, 5.2%, 6.6% and 5.1% lower than strength exertions of the dominant hand for the lateral pinch strength, key pinch strength, tip-to-tip pinch strength and three-jaw pinch strength exertions, respectively.Conclusion: These findings can be used to fill the gaps in strength data for Iranian population.
