Рассмотрена методика расчета биомеханических характеристик голеностопного сустава: жесткости сустава и моментов инерции стопы. В основу исследований положены экспериментальные данные сгибания- разгибания-ротации голеностопного сустава и реакций стопы при ходьбе, полученные в лаборатории кинезиологии и биомеханики Тартуского университета Эстонии. Метод. При расчете моментов инерции стопы применен закон сохранения кинетического момента с использованием данных о реакции стопы и последующей оценки импульса реактивной силы. Для оценки жесткости голеностопного сустава использованы данные эксперимента в фазе переноса стопы. Основные результаты. На основании экспериментальных данных реакций ступни и данных маркеров по угловым перемещениям рассчитаны моменты инерции стопы относительно двух осей голеностопного сустава. Для оценки жесткости сустава использованы данные эксперимента в фазе переноса стопы с последующим моделированием ее движения в этой фазе. Обсуждение. Результаты исследования могут помочь в разработке роботов с нижними конечностями. Кроме того, линейку данных по жесткостям голеностопного сустава можно использовать в качестве основы при разработке протоколов реабилитации сустава для конкретного пациента.</p></abstract><trans-abstract xml:lang="en"><p>Calculation method for ankle joint biomechanical characteristics is developed: gear relation, ankle joint rigidity, foot inertia moment. The basis of research is the experimental data on flexion-extension-rotation movement of ankle joint and foot walking reaction obtained in the laboratory of kinesiology and biomechanics of the Tartu University, Estonia. Conservation principles of angular momentum were used for foot inertia moments calculation. Angular momentum was calculated according to foot reaction and further estimation of reactive force impulse data. The free transfer dynamics method (FTD-method) was suggested that allowed assessing ankle joint rigidity. Ankle joint gear relation has been calculated for the first time. Foot inertia moments in reference to two ankle joint axes have been calculated on the basis of foot reaction experimental data and angular movement markers data. Experimental data in the phases of foot transfer with further foot movement modeling in this phases have been used in order to assess ankle joint rigidity. Practical relevance of this research is defined by the perspective of further researches and experiments, for example, with the usage of inertial sensors for personalized walk data assessment for patients with remote condition monitoring and information transfer to rehabilitation centers. The given assessments of angle joint rigidity are useful for biomechatronic systems engineering.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>голеностопный сустав</kwd><kwd>сгибание/разгибание</kwd><kwd>ротация</kwd><kwd>передаточные отношения</kwd><kwd>момент инерции</kwd><kwd>жесткость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ankle joint</kwd><kwd>flexion/extension</kwd><kwd>rotation</kwd><kwd>gear relation</kwd><kwd>inertia moment</kwd><kwd>stiffness</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Министерства науки и высшего образования Российской Федерации (проект  № 124041500009-8).</funding-statement><funding-statement xml:lang="en">This work was supported by the Ministry of Science and Higher Education of the Russian Federation (project No. 124041500009-8).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Donatelli R.A.
