РАЗРАБОТКА НОВОЙ КОНСТРУКЦИИ ОБУВИ ДЛЯ МЕДИЦИНСКИХ РАБОТНИКОВ И ОЦЕНКА ЕЁ ЭРГОНОМИЧЕСКИХ ПОКАЗАТЕЛЕЙ ПО РЕЗУЛЬТАТАМ ОПЫТНОЙ ЭКСПЛУАТАЦИИ

Abstract

One of the most effective approaches to preventing occupational disorders among healthcare workers is the use of specialized footwear that meets modern ergonomic, functional, and hygienic requirements. This study presents the results of developing a novel footwear design for healthcare professionals and a comprehensive evaluation of its ergonomic and performance characteristics based on laboratory testing and wear trials. A medical footwear model with a cemented sole construction, a knitted upper, and a multilayer removable insole incorporating a natural loofah layer and an arch support element was developed. Compliance of the developed footwear with the requirements of GOST 1135-2005 was confirmed through laboratory testing of footwear weight, flexibility, and outsole bonding strength. The ergonomic and performance characteristics of the footwear were assessed during wear trials involving healthcare professionals from various medical specialties using a structured questionnaire followed by statistical analysis of the collected data. The evaluated parameters included wearing comfort, size fit, cushioning performance, breathability, slip resistance, structural stability, and overall user satisfaction. The results confirmed that the developed footwear design complies with current requirements for medical footwear, demonstrates a high level of ergonomic performance, and has strong potential for practical application in healthcare institutions.
