Carrying angle is one of the secondary sexual characteristics which is important for keeping the hand away from body to improve functionality. A cross-sectional survey was conducted in Western Indian population (rural and urban population in and around Jodhpur district) during July 2014-June 2016 with the purpose of evaluating the carrying angle in apparently healthy adult and determines the range of normality according to age, sex, height, waist circumference and special reference to handedness. The carrying angle (elbow) was measured in 504 adults aged between 20-40 years (by simple random sampling) by a digital Goniometer. The subjects were in anatomical position (stand up straight, roll his/her shoulders back and the elbow was fully extended and the forearm fully supinated) while the carrying angle were taken. Carrying angle of the right side in male's 11.54°±1.29° and in female's 13.41°±1.26°, whereas these value in left side 10.21°±1.34° and 12.19°±1.44° respectively. All measurements in females are significantly higher in comparison to males (p<0.001). The significant difference was observed in carrying angle according to handedness; dominant hand had higher value of carrying angle in comparison to non-dominant hand in both gender (p<0.001). The height of individuals is positively correlated with the angle whereas there was no correlation was found in between age, waist circumference. The present study showed that the females have greater carrying angle than males.
携带角是次要性特征之一,对于保持手部远离身体以提高功能很重要。本研究于 2014 年 7 月至 2016 年 6 月在西印度人群(焦特布尔地区的农村和城市人口)中进行了横断面调查,目的是评估明显健康成年人的携带角,并根据年龄、性别、身高、腰围以及对惯用手的特殊参考来确定正常范围。通过数字量角器对 504 名年龄在 20-40 岁之间的成年人(采用简单随机抽样)进行了携带角测量。在解剖学位置(站直,双肩向后滚动,肘部完全伸展,前臂完全旋后)下进行测量。男性右侧携带角为 11.54°±1.29°,女性为 13.41°±1.26°,而左侧男性为 10.21°±1.34°,女性为 12.19°±1.44°。女性的所有测量值均显著高于男性(p<0.001)。根据惯用手,携带角存在显著差异;无论性别,惯用手的携带角度都高于非惯用手(p<0.001)。个体的身高与角度呈正相关,而年龄、腰围之间没有相关性。本研究表明,女性的携带角大于男性。
