The hand anthropometric data is the baseline for design of hand tools and equipment.
This study aimed to generate the hand anthropometric database of male and female agricultural workers and compare it with the hand anthropometric data of other regions of India. The use of collected data is illustrated to design hand tools and protective gear.
Hand anthropometric data were collected from 228 male and 198 female agricultural workers of northeast India. A total of 35 hand dimensions, stature and body mass from different tribes in the age group of 18-60 years were precisely measured. Measured data were statistically analysed to study the effects of gender, ethnicity, and age on hand dimensions. Correlation coefficients were determined among hand dimensions and linear regression equations were developed between highly correlated dimensions.
The results show that all hand dimensions of the male and female subjects are significantly different (p < 0.01). Most of the hand dimensions were significantly different (p < 0.05) among different tribes for the male subjects. However, less number of hand dimensions were significantly different among tribes for the female subjects. Age of the subjects has significant effects (p < 0.01) on dimensions related to thickness, depth and circumference of fingers. The use of these data in the ergonomic design of hand tools and personal protective gear is illustrated to increase safety and comfort as well as efficiency of operators.
There is a difference in the hand dimensions of different tribes of northeast India. This needs to be considered when designing agricultural hand tools and equipment.
手部人体测量数据是设计手部工具和设备的基础。
本研究旨在生成印度东北部男性和女性农业工人的手部人体测量数据库，并将其与印度其他地区的手部人体测量数据进行比较。说明了收集到的数据可用于设计手部工具和防护装备。
从印度东北部的 228 名男性和 198 名女性农业工人中收集了手部人体测量数据。总共精确测量了来自不同部落的 35 个手部尺寸、身高和体重，年龄在 18-60 岁之间。对测量数据进行了统计分析，以研究性别、种族和年龄对手部尺寸的影响。确定了手部尺寸之间的相关系数，并建立了高度相关尺寸之间的线性回归方程。
结果表明，男性和女性受试者的所有手部尺寸均有显著差异（p<0.01）。大多数手部尺寸在男性受试者中存在显著差异（p<0.05），不同部落之间。然而，女性受试者中，手部尺寸之间的差异较小。受试者的年龄对手指厚度、深度和周长等相关尺寸有显著影响（p<0.01）。这些数据可用于手部工具和个人防护装备的人体工程学设计，以提高操作员的安全性、舒适性和效率。
印度东北部不同部落的手部尺寸存在差异。在设计农业手部工具和设备时需要考虑到这一点。
