Conventional scales and group-based statistical tests poorly capture small but clinically significant improvements after rehabilitation. This highlights the need for new methods of objective evaluation of rehabilitation effectiveness.</p> <p><bold>AIM:</bold> The work aimed to compare the performance of an individualized statistical method of magnitude-based decisions in interpreting instrumented gait analysis data obtained with inertial sensors for assessing rehabilitation effectiveness in children with hemiparetic cerebral palsy, with conventional group statistical approaches (p-value).</p> <p><bold>METHODS:<italic> </italic></bold>This was an observational, single-center, prospective, continuous study. It was based on the analysis of instrumented gait analysis with inertial sensors protocols performed before and after a rehabilitation course in children aged 8–17 years with hemiparetic cerebral palsy at the Department of Pediatric Medical Rehabilitation, Russian Children’s Clinical Hospital.</p> <p><bold>RESULTS:<italic> </italic></bold>In a cohort of 23 children with hemiparetic cerebral palsy, the standard paired t-test did not reveal statistically significant group changes in spatiotemporal gait parameters (p &gt; 0.05 for all indicators). However, individualized MBD analysis recorded clinically significant positive changes in most patients: increased step velocity and cycle length on the paretic side (in 47% and 33% of cases, respectively), greater ranges of motion in the knee (67%) and ankle (40%) joints, improved foot clearance (47%), as well as reduced pathological compensations in the lumbosacral region (53%). Thus, the MBD method demonstrated greater sensitivity to individual rehabilitation effects, detecting improvements that remained unnoticed with the classical group-based approach.</p> <p><bold>CONCLUSION:<italic> </italic></bold>Individualized MBD analysis makes it possible to objectively register clinically significant improvements in gait that are not detected by conventional group tests, thereby justifying its use for evaluating rehabilitation effectiveness.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Нарушения походки являются ключевым фактором инвалидизации у детей с детским церебральным параличом (ДЦП). Классические шкалы и групповые статистические тесты плохо распознают малые, но клинически значимые улучшения после реабилитации. Это определяет необходимость поиска новых методов объективной оценки эффективности проводимой реабилитации.</p> <p><bold>Цель.</bold> Сравнить оценку индивидуализированного статистического метода принятия решений на основе величины эффекта (magnitude-based decision, MBD) при интерпретации данных инструментального анализа походки с применением инерциальных сенсоров (ИАПИС) для определения эффективности курса реабилитации у детей с гемипаретической формой ДЦП с оценкой общепринятыми групповыми статистическими подходами (<italic>p</italic>-значение).</p> <p><bold>Материалы и методы.</bold> Данное исследование является обсервационным, одноцентровым, проспективным, сплошным. Оно основано на анализе протоколов ИАПИС, проведённых в рамках оценки до и после курса реабилитации у детей 8–17 лет с гемипаретической формой ДЦП в отделении медицинской реабилитации для детей Российской детской клинической больницы.</p> <p><bold>Результаты. </bold>В когорте из 23 детей с гемипаретической формой ДЦП стандартный парный t-тест не выявил статистически значимых групповых изменений пространственно-временных параметров походки (<italic>p</italic> &gt;0,05 по всем показателям). Однако индивидуализированный анализ MBD зафиксировал клинически значимую положительную динамику у большинства пациентов: увеличение скорости шага и длины цикла на паретичной стороне (у 47 и 33% соответственно), расширение амплитуд движений в коленном (67%) и голеностопном (40%) суставах, повышение высоты подъёма стопы (47%), а также снижение патологических компенсаций в пояснично-крестцовом отделе (53%). Таким образом, метод MBD продемонстрировал более высокую чувствительность к индивидуальным эффектам реабилитации, выявив улучшения, незаметные при классическом групповом подходе.</p> <p><bold>Заключение.</bold> Индивидуализированный MBD-анализ позволяет объективно регистрировать клинически значимые улучшения походки, не выявляемые классическими групповыми тестами, и обосновывает целесообразность его применения при анализе эффективности реабилитации.</p></trans-abstract><trans-abstract xml:lang="zh"><p><bold>论证：</bold>步态障碍是导致脑瘫儿童残疾的主要因素。传统评分量表和群体统计检验方法往往难以检测康复后虽幅度较小但具有临床意义的改善。因此需要寻找新的客观评估康复疗效的方法。</p> <p><bold>目的：</bold>比较基于效应量的个体化统计决策方法（magnitude-based decision, MBD）与传统群体统计方法（p值）在基于惯性传感器（instrumental analysis of inertial sensors, IAIS）的步态分析中的应用效果，以评估其在偏瘫型脑瘫儿童康复疗效评估中的价值。</p> <p>材料与方法。本研究为观察性、单中心、前瞻性、全样本研究。它基于对在Russian Children’s Clinical Hospital儿童康复科进行的IAIS步态分析的记录进行分析，这些分析在8–17岁偏瘫型脑瘫患儿康复前后完成。</p> <p><bold>结果：</bold>在23名偏瘫型脑瘫患儿中，传统的配对t检验未发现步态时空参数的群体水平显著性变化（所有指标p均大于0.05）。然而，MBD个体化分析显示多数患者存在临床意义上的改善：患侧步速与步长增加（分别为47%和33%的患者），膝关节与踝关节活动度增大（分别为67%和40%的患者），足部抬高高度增加（47%），以及腰骶部病理性代偿运动减少（53%）。因此，MBD方法在康复的个体效果方面表现出更高的敏感性，能够发现传统群体方法未能发现的改善。</p></trans-abstract><kwd-group xml:lang="en"><kwd>cerebral palsy in children</kwd><kwd>gait analysis</kwd><kwd>magnitude-based decision</kwd><kwd>personalized rehabilitation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>детский церебральный паралич</kwd><kwd>анализ походки</kwd><kwd>magnitude-based decision</kwd><kwd>персонифицированная реабилитация</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>脑性瘫痪</kwd><kwd>步态分析</kwd><kwd>magnitude-based decision</kwd><kwd>个体化康复。</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Akhmatkhanova НН, Badalyan OL, Bril AG, et al.
