Data on the physical strength capabilities of users are essential for designing the safe and usable products.
The aims of this study were to characterise the wrist ulnar/radial (U/R) torque strength and individual strength differences among Iranian population.
The study was conducted among 769 (391 males, 378 females) participants aged 5-74 years in the northwest of Iran. Measurements were carried out with both dominant and non-dominant hands using a digital angle torque adaptor installed in a jar-shaped measuring unit.
The results indicated that the mean wrist U/R torque strength exertion by females was 75% of that exerted by males. Strength exertion with the non-dominant hand was 8% lower than strength exertion of the dominant hand. A significant positive association was also found between the wrist U/R torque strength and body mass index.
This additional information on the wrist torque strength can fill the gap in the strength data for Iranian population, or used by health and safety practitioners in the field.
用户身体力量能力的数据对于设计安全且易用的产品至关重要。
本研究的目的是描述伊朗人群手腕尺侧/桡侧（U/R）扭矩力量及个体力量差异。
该研究在伊朗西北部769名年龄在5至74岁的参与者（391名男性，378名女性）中进行。使用安装在罐形测量装置中的数字角度扭矩适配器对优势手和非优势手进行测量。
结果表明，女性手腕U/R扭矩力量的平均 exertion 是男性的75%。非优势手的力量 exertion 比优势手低8%。手腕U/R扭矩力量与体重指数之间也存在显著的正相关。
这些关于手腕扭矩力量的额外信息可以填补伊朗人群力量数据的空白，或供该领域的健康与安全从业者使用。
