Initially validated in MATLAB, the algorithmic framework was adapted into a cross-platform desktop application with a graphical user interface. Kinematic 4 processes coordinate data from markers placed on the thumb, index finger, wrist, object, and specialized glasses with a movable shutter. The program identifies six critical time points: experiment onset, hand lifting, finger opening, maximum grasp aperture, object lifting, and object placement.</p><p><bold>Results. </bold>Comparison between results obtained using Kinematic 4 and those generated by the original MATLAB script demonstrated full consistency. The software was successfully validated on experimental datasets and showed high stability. Its user-friendly interface and automated workflow make it a reliable and reproducible tool for both research and clinical applications.</p><p><bold>Conclusion.</bold> Kinematic 4 can be effectively used for assessing upper-limb movements in neuroscience and clinical contexts, including the diagnosis of motor impairments and monitoring of recovery dynamics. Future development may include integration with other biosignals and machine learning modules for predictive analytics.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – представить программное обеспечение Kinematic 4, предназначенное для автоматизированного анализа кинематических характеристик действий захвата и переноса объектов рукой на основе данных, полученных с помощью систем захвата движения.</p><p><bold>Материалы и методы.</bold> Программа разработана на языке Python и реализует алгоритмы автоматического определения ключевых временных точек двигательного акта. Исходная алгоритмическая структура была апробирована ранее в среде MATLAB и адаптирована в виде кроссплатформенного настольного приложения с графическим интерфейсом. Kinematic 4 позволяет анализировать координатные данные, полученные от трекеров, размещенных на пальцах, запястье, объекте и специализированных очках с подвижной створкой. Программа определяет 6 временных маркеров, соответствующих этапам выполнения действия: начало эксперимента, начало движения кисти, начало раскрытия пальцев, максимальную апертуру захвата, начало подъема объекта и его опускание.</p><p><bold>Результаты.</bold> Сравнительный анализ результатов, полученных с помощью Kinematic 4 и ранее разработанного MATLAB-скрипта, показал полное соответствие. Программа успешно прошла верификацию на экспериментальных данных и продемонстрировала стабильную работу. Благодаря интуитивно понятному интерфейсу и автоматизации расчетов Kinematic 4 обеспечивает воспроизводимый и удобный инструмент для научных и клинических исследований.</p><p><bold>Выводы.</bold> Программное обеспечение может быть эффективно использовано для оценки движений руки в нейронаучных и клинических задачах, включая диагностику моторных нарушений и мониторинг восстановительных процессов. В перспективе возможны интеграция с другими биофизическими сигналами и внедрение элементов интеллектуального анализа данных.</p></trans-abstract><kwd-group xml:lang="en"><kwd>kinematic analysis</kwd><kwd>motion capture</kwd><kwd>motor planning</kwd><kwd>rehabilitation</kwd><kwd>neurodiagnostics</kwd><kwd>Python</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>кинематический анализ</kwd><kwd>система захвата движения</kwd><kwd>моторное планирование</kwd><kwd>реабилитация</kwd><kwd>нейродиагностика</kwd><kwd>Python</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was carried out within the framework of the Fundamental Research Program of the National Research University “Higher School of Economics”</funding-statement><funding-statement xml:lang="ru">Исследование осуществлено в рамках Программы фундаментальных исследований ФГАОУ ВО «Национальный исследовательский университет «Высшая школа экономики».</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>MacKenzie C.
