Its consequences include increased risk of falls and functional limitations, which can significantly reduce the quality of life.</p> <p><bold>AIM:</bold> To investigate the functional profile of hemiparesis resulting from subacute ischemic stroke.</p> <p><bold>MATERIALS AND METHODS:</bold> This observational, retrospective, one-stage, single-center study analyzed primary biomechanical gait parameters in 31 patients and 34 healthy controls. Spatial, temporal, kinematic, and electromyographic characteristics were recorded. A statistical assessment and inter-group and intra-group comparison of the collected data were performed to identify the pathognomonic features of hemiplegic gait in patients with subacute stroke.</p> <p><bold>RESULTS:</bold> Changes in gait biomechanics typical for hemiparetic patients who have suffered from ischemic stroke were described: slight asymmetry of step cycle, normal duration of support period on the paretic side, significant increase in duration of support period on the healthy side, and shortening of single support period on the paretic side. Additionally, the asymmetry of the walking function was characterized by changes in reciprocity, that is, a harmonious sequence of step cycles. The function of the hip and knee joints was reduced and altered, and the amplitude of the ankle joint was increased. Decrease and change in the bioelectric activity profile of muscles were detected. Moreover, the quadriceps femoris function was least affected.</p> <p><bold>CONCLUSION:</bold> The main changes in walking function are characterized by an asymmetry of spatiotemporal parameters, a decrease in movement amplitudes of the hip and knee joints on the paretic side, an increase in ankle joint amplitude, a decrease in the bioelectric activity of muscles, and a shift in the phases of their activity. The results contribute to a better understanding of the mechanisms behind hemiplegic gait and provide a valuable tool for developing more personalized and targeted rehabilitation plans for patients suffering from hemiparesis as a result of subacute ischemic stroke.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Нарушение походки, наблюдаемое у 80% пациентов, перенёсших инсульт, приводит к повышенному риску падений, снижению функциональной независимости и, как следствие, влияет на качество жизни.</p> <p>Цель исследования ― изучить функциональную картину гемипареза в раннем восстановительном периоде инсульта.</p> <p><bold>Материалы и методы.</bold> Проведено обсервационное ретроспективное одномоментное одноцентровое исследование, включавшее анализ первичных биомеханических параметров ходьбы у 31 пациента и 34 человек контрольной группы. Регистрировались пространственные, временные, кинематические и электромиографические характеристики. Проведены статистическая оценка, а также межгрупповое и внутригрупповое сравнение полученных параметров для определения патогномоничных особенностей походки при гемиплегии в раннем восстановительном периоде инсульта.</p> <p><bold>Результаты.</bold> Выявлены изменения биомеханики ходьбы, типичные для пациентов с гемипарезом, перенёсших инсульт: лёгкая асимметрия цикла шага, нормальная продолжительность периода опоры на паретичной стороне, значительное увеличение продолжительности периода опоры на здоровой стороне, а также укорочение периода одиночной опоры на паретичной стороне. Кроме того, асимметрия функции ходьбы характеризовалась изменением реципрокности, т.е. гармоничной последовательности циклов шага, снижением и изменением функции тазобедренного и коленного сустава, увеличением амплитуды голеностопного сустава, снижением и изменением профиля биоэлектрической активности мышц, при этом менее всего страдала функция четырехглавой мышцы бедра (<italic>musculus</italic><italic> </italic><italic>quadriceps</italic><italic> </italic><italic>femoris</italic>).</p> <p><bold>Заключение.</bold> Основные изменения функции ходьбы характеризуются асимметрией пространственно-временных характеристик, снижением амплитуды движений в тазобедренном и коленном суставах паретичной стороны, увеличением амплитуды в голеностопном суставе, снижением биоэлектрической активности мышц и смещением фаз их активности. Полученные результаты могут способствовать лучшему пониманию механизмов гемиплегической походки и стать инструментом для разработки более персонализированного, целенаправленного плана реабилитации пациентов с гемипарезом в раннем восстановительном периоде ишемического инсульта.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ischemic stroke</kwd><kwd>paresis</kwd><kwd>gait analysis</kwd><kwd>biomechanics</kwd><kwd>electromyography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ишемический инсульт</kwd><kwd>парез</kwd><kwd>анализ ходьбы</kwd><kwd>биомеханика</kwd><kwd>электромиография</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Federal Medical and Biological Agency (FMBA of Russia): АААА-А19-119042590030-2</funding-statement><funding-statement xml:lang="ru">Федеральное медико-биологическое агентство (ФМБА России): АААА-А19-119042590030-2</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Martin SS, Aday AW, Almarzooq ZI, et al. 2024 Heart disease and stroke statistics: A report of US and global data from the American Heart Association.
