Abstract

Force estimating insoles offer a mobile alternative to in-ground force plates for measuring ground reaction forces (GRFs) and centre of pressure (CoP) in occupational settings. However, their validity in measuring GRFs for occupational tasks has yet to be validated and CoP estimation approach has yet to be developed. This study developed this method for a three-compartment force estimating insole and introduced a force drift correction approach. Thirty-nine participants completed lifting, packaging, palletising, and above shoulder work tasks while wearing insoles on force plates. A weighted algorithm and linear drift correction were developed and compared against force plate data. The CoP method resulted in root mean squared errors (RMSEs) between 1.7 and 3.4 cm. Drift correction reduced ground reaction force RMSE by approximately 28 N. These findings suggest that three-compartment force insoles may be able to provide valid CoP and force estimates, making them a prospective tool for in-field biomechanical measurements of occupational tasks.

验证力估计鞋垫计算压力中心和垂直地面反作用力在职业任务。

力估计鞋垫提供了一个移动替代地面力板测量地面反作用力（GRFs）和压力中心（CoP）在职业设置。然而，它们在测量职业任务的GRFs方面的有效性尚未得到验证，CoP估计方法尚未开发。本研究开发了三室力估计鞋垫的方法，并引入了力漂移校正方法。39名参与者完成了举重、包装、托盘和肩膀以上的工作任务，同时在受力板上穿了鞋垫。提出了一种加权算法和线性漂移修正，并与测力板数据进行了比较。CoP方法的均方根误差（rmse）在1.7 ~ 3.4 cm之间。漂移修正使地面反作用力RMSE减少了大约28牛。这些发现表明，三室力鞋垫可能能够提供有效的CoP和力估计，使其成为职业任务的现场生物力学测量的前瞻性工具。

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
