Объектом исследования являлась динамика функционального состояния организма человека при выполнении физической работы с применением промышленного экзоскелета, предназначенного для разгрузки мышц спины и рук при подъёме, опускании, переносе и удерживании грузов массой до 50 кг. Исследование проведено с целью оценки эффективности применения промышленного экзоскелета для снижения утомления в условиях моделирования трудовой деятельности.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Модель трудовой деятельности работника, связанная с подъёмом, перемещением и удержанием груза, была разработана в условиях лаборатории. Для оценки эффективности применения промышленного экзоскелета проводилось сравнение степеней утомления по показателям функционального состояния скелетной мускулатуры при выполнении трудовой деятельности в лабораторных условиях с применением промышленного экзоскелета и без него. Использованы следующие медико-биологические методы: электромиография, миотонометрия и анкетирование. Полученные данные подвергали статистическому анализу.</p></sec><sec><title>Результаты</title><p>Результаты. При выполнении работы с применением экзоскелета некоторые мышцы были в состоянии меньшего напряжения, чем при работе без него. Анализ субъективной оценки локального напряжения показывал, что физическое напряжение добровольцев было ниже при работе в экзоскелете по сравнению с работой без него.</p></sec><sec><title>Ограничения исследования</title><p>Ограничения исследования. Небольшой объём выборки, моделирование трудовой деятельности в лаборатории не позволяют учесть всех факторов, которые воздействуют на работника, использующего экзоскелет, на производстве. Для более полной оценки эффективности промышленного экзоскелета необходим учёт динамики показателей сердечно-сосудистой, дыхательной и других систем организма.</p></sec><sec><title>Заключение</title><p>Заключение. С точки зрения влияния использования промышленного экзоскелета на утомление при выполнении производственных операций, аналогичных лабораторной модели трудовой деятельности, можно сделать заключение об эффективности применения промышленного экзоскелета.</p><p>Соблюдение этических стандартов. Исследование проведено с соблюдением протокола «Исследование безопасности и эффективности применения промышленных экзоскелетов ProEXOLight и ProEXOSuperLight», одобренного Локальным этическим комитетом ФГБНУ «НИИ МТ» (протокол № 1 заседания Локального этического комитета от 25.01.2023 г.), соответствует общепринятым научным принципам Хельсинкской декларации Всемирной медицинской ассоциации.

The object of the study was the trend in the functional state in the human body when performing physical work using an industrial exoskeleton designed to unload the muscles of the back and arms when lifting, lowering, carrying, and holding loads weighing up to 50 kg. The study was conducted to evaluate the efficiency of applying an industrial exoskeleton to reduce fatigue in a work simulation environment. </p></sec><sec><title>Materials and methods</title><p>Materials and methods. In the laboratory, a model of an employee’s work related to lifting, moving, and holding cargo was developed. To assess the efficiency of the application of an industrial exoskeleton, a comparison was made of the degrees of fatigue in terms of the functional state of skeletal muscles when performing laboratory model of labor activity with and without an industrial exoskeleton. The following biomedical methods were used: electromyography, myotonometry, and questionnaires. The data obtained was subjected to statistical analysis.</p></sec><sec><title>Results</title><p>Results. When working with an exoskeleton, some muscles were in a state of less tension than when working without it. The results of the analysis of the subjective assessment of local stress showed the physical stress in the volunteers to be lower when working in an exoskeleton compared to working without it.</p></sec><sec><title>Limitations</title><p>Limitations. A small sample size and modeling in labour activity in the laboratory does not allow taking into account all the factors that affect an employee using an exoskeleton in production. For a more complete evaluation of the efficiency of an industrial exoskeleton, it is necessary to take into account the dynamics of indicators of the cardiovascular, respiratory and other body systems.</p></sec><sec><title>Conclusions</title><p>Conclusions. From the point of view of the influence of the application of an industrial exoskeleton on the fatigue during production operations similar to the laboratory model of labor activity, it is possible to conclude about the efficiency of the application of an industrial exoskeleton.</p><p>Compliance with ethical standards. The study was conducted in compliance with the protocol “Research on the safety and efficiency of the application of an industrial exoskeletons «ProEXOLight» и «ProEXOSuperLight»», approved by the Local Ethics Committee of the Izmerov Research Institute of Occupational Health (protocol No. 1 of the meeting of the Local Ethics Committee dated 25/01/2023) and the Helsinki Declaration of the World Medical Association (as amended 2013) was carried out. All participants gave informed voluntary written consent to participate in the study.</p></sec><sec><title>Contribution</title><p>Contribution: Shuporin E.S. – concept and design of the study, writing text, editing; Chudova E.S. – writing text, editing; Ilyenko O.V. – concept and design of research, writing text; Vaga I.N., Motkova T.Yu. – collection and processing of material, statistical processing.
