The design and shape of hand tool handles are critical factors for preventing musculoskeletal disorders (MSDs) caused by the use of hand tools. We explored how these factors are related to total force and individual finger force in males and females with various hand anthropometrics. Using the MFFM system, we assessed four indices of anthropometry, and measured total force and individual finger force on various handle designs and shapes. Both total force and individual finger force were significant according to gender and handle shape. Total grip strength to the handle shape indicated the greatest strength with D shape and the least with A shape. From the regression analysis of hand anthropometric indices, the value of R was respectably high at 0.608-0.696. The current study examined the gender and handle shape factors affecting grip strength based on the force measurements from various handle types, in terms of influence on different hand anthropometric indices.
手动工具手柄的设计和形状是预防因使用手动工具而导致肌肉骨骼疾病（MSD）的关键因素。我们探讨了这些因素如何与具有不同手部人体测量学特征的男性和女性的总力及各手指力相关。使用MFFM系统，我们评估了四项人体测量学指标，并测量了不同手柄设计和形状下的总力及各手指力。总力和各手指力在性别和手柄形状方面均存在显著差异。针对手柄形状的总握力显示，D形手柄的握力最大，A形手柄的握力最小。通过对手部人体测量指标的回归分析，R值相当高，在0.608 - 0.696之间。本研究基于对不同手柄类型的力测量，从对不同手部人体测量指标的影响方面，考察了影响握力的性别和手柄形状因素。
