Abstract

Insoles are typically worn to increase comfort in performing daily activities. Many studies have investigated the effects of insoles with different properties. This study performed an ergonomic evaluation of three insole types, with a focus on assessing the effectiveness of an insole padding system (IPS). The objectives of this study were (1) to perform an ergonomic evaluation of three insoles and (2) to perform a field validation study to examine the effectiveness of IPS wearing among nurses. The study involved two phases. In the first phase, 15 healthy females participated in an experiment evaluating three insoles (general flat insole, ergo-insole, and IPS). The outcome measurements were electromyography activity of four muscles, plantar pressure distribution in seven zones, and subjective discomfort rating. In the second phase, 100 nurses were recruited for the Nordic Musculoskeletal Questionnaire survey and 43 nurses participated in the field evaluation study. The results indicated that walking with the IPS was associated with lower plantar pressures in the midfoot and heel regions. Participants who wore ergo-insole and IPS exhibited lower overall subjective discomfort ratings. Lower-extremity discomfort was significantly improved after wearing the IPS for 2 weeks. The findings of this study suggest that walking with the IPS can result in less discomfort in the lower extremities than walking with the conventional insoles. IPS wearing is effective in improving lower-extremity discomfort in persons who require prolonged standing and walking in daily life.

鞋垫填充系统的人体工程学评估和现场验证
鞋垫通常是为了增加日常活动的舒适度而穿的。许多研究调查了不同性质的鞋垫的效果。本研究对三种鞋垫类型进行了人体工程学评估,重点是评估鞋垫填充系统(IPS)的有效性。本研究的目的是:(1)对三种鞋垫进行人体工程学评估;(2)进行现场验证研究,以检验护士穿着IPS的有效性。这项研究包括两个阶段。在第一阶段,15名健康女性参与了一项评估三种鞋垫(普通平底鞋垫、麦角鞋垫和IPS)的实验。结果测量是4块肌肉的肌电活动、7个区域的足底压力分布和主观不适评分。第二阶段招募100名护士参与北欧肌肉骨骼问卷调查,43名护士参与现场评价研究。结果表明,使用IPS行走与脚掌中部和跟区较低的足底压力有关。穿ergos鞋垫和IPS的参与者表现出较低的总体主观不适评分。佩戴IPS 2周后,下肢不适明显改善。这项研究的结果表明,与使用传统鞋垫相比,使用IPS鞋垫行走可以减少下肢的不适。在日常生活中需要长时间站立和行走的人群中,IPS佩戴对改善下肢不适是有效的。
