The study group consisted of 17 children diagnosed with psoriasis and PsA (n=17). The control group included 17 children with conditions unrelated to significant neurological disorders or musculoskeletal abnormalities that could affect gait biomechanics (n=17). Gait parameters were recorded using the Stedis trainer, which utilizes eight biometric sensors placed on the lower extremities — on the feet, lower third of the shins, upper third of the thighs, sacrum, and at the level of the 12<sup>th</sup> thoracic vertebra. Spatiotemporal and kinematic gait parameters were analyzed.</p> <p><bold>RESULTS</bold>: A comparative analysis was conducted between the two groups: the control group (children without significant neurological or musculoskeletal abnormalities affecting gait biomechanics) and the PsA group. Children with PsA demonstrated an increased stance phase duration and single-limb support time on the affected lower limb compared to the control group. The swing phase duration of the affected limb was reduced by approximately 1.5% compared to the healthy limb. The foot-lift height of the affected limb was found to be 5 cm higher than that of the healthy limb. Compared with the control group, single-limb support time for the healthy leg in control group children was nearly 4% higher than in children with PsA. The differences were statistically significant (р=0.009). The swing phase duration for the affected lower limb in children with PsA was 2.3% higher than in the control group. The differences were statistically significant (р=0.019). The overall swing phase duration was nearly 4% higher in the control group (р=0.019), with statistically significant differences. The differences were statistically significant (р=0.019).</p> <p><bold>CONCLUSION</bold>: The development of a gait pattern characteristic of PsA is determined by own mechanisms distinct from those in other types of arthritis.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность</bold>. Инструментальный анализ походки предоставляет возможность объективной количественной оценки характерного паттерна движений человека.</p> <p><bold>Цель исследования</bold><bold> </bold>— изучение количественных показателей инструментального анализа походки с использованием инерционных датчиков у детей со псориатическим артритом (ПсА) для определения маркеров ранней диагностики и возможности их применения при оценке эффективности методов медицинской реабилитации.</p> <p><bold>Материалы</bold><bold> </bold><bold>и</bold><bold> </bold><bold>методы</bold>. В исследование включены 34 ребенка в возрасте от 11 до 17 лет. В группу исследования вошли 17 детей с диагнозом «псориаз, ПсА» (<italic>n</italic>=17). В группе сравнения изучены 17 детей контрольной группы с заболеваниями без значимых неврологических нарушений и изменений опорно-двигательного аппарата, влияющих на биомеханику походки (<italic>n</italic>=17). Для регистрации параметров ходьбы пациента с помощью тренажёра «Стедис» использовали 8 биометрических сенсоров, которые устанавливали на нижние конечности в области стоп, нижней трети голеней, верхней трети бёдер, крестца и на уровне 12-го грудного позвонка. Во время исследования фиксировали временно-пространственные и кинематические параметры ходьбы.</p> <p><bold>Результаты</bold>. Провели сравнительный анализ двух групп выборки: контрольная группа детей с заболеваниями без значимых неврологических нарушений и изменений опорно-двигательного аппарата, влияющих на биомеханику походки, и группа детей с диагнозом ПсА. Наблюдали увеличение периода опоры, одиночной опоры у поражённой нижней конечности у детей со ПсА в сравнении с группой контроля. Период переноса для поражённой конечности уменьшен по сравнению со здоровой ногой почти на 1,5%. Обнаружили, что высота подъёма стопы у поражённой конечности на 5 см выше, чем у здоровой. При сравнительном анализе с детьми контрольной группы одиночная опора для здоровой ноги у детей контрольной группы почти на 4% выше, чем у детей со ПсА. Различия статистически значимы (<italic>р</italic>=0,009). Для поражённой нижней конечности период переноса у детей со ПсА выше на 2,3%, чем у детей контрольной группы. Различия статистически значимы (<italic>р</italic>=0,019). Период переноса почти на 4% выше у детей контрольной группы. Различия статистически значимы (<italic>р</italic>=0,019).</p> <p><bold>Заключение</bold>. Формирование паттерна, характерного для ПсА, определяется механизмами развития, отличными от других артритов.</p></trans-abstract><trans-abstract xml:lang="zh"><p>背景。仪器步态分析（Instrumental gait analysis, IGA）提供了一种客观且定量的方式来评估人体运动模式的特征。</p> <p>研究目的。 研究患有银屑病关节炎（Psoriatic Arthritis, PsA）儿童的步态定量参数，利用惯性传感器识别早期诊断标志物，并评估其在医学康复中的应用潜力。</p> <p>材料与方法。本研究纳入 34 名年龄在 11 至 17 岁之间的儿童。其中，研究组包括 17 名确诊为银屑病及银屑病关节炎的儿童（n=17）；对照组包括 17 名无明显神经系统障碍及无影响步态生物力学的肌肉骨骼疾病的儿童（n=17）。 步态参数的记录采用 “Stedis” 训练系统，使用 8 个生物传感器，分别固定于双下肢的足部、小腿远端、大腿近端、骶骨以及第 12 胸椎水平处。在实验过程中，记录步态的时空参数和运动学参数。</p> <p>结果。本研究对比分析了两组儿童的步态特征：对照组为无明显神经系统损伤或影响步态生物力学的肌肉骨骼疾病的儿童，研究组为确诊银屑病关节炎（PsA）的儿童。研究结果显示，与对照组相比，PsA 组儿童受累下肢的支撑期和单支撑期时间均有所延长。受累下肢的摆动期时间比健侧缩短约 1.5%。此外，受累下肢的足部抬升高度比健侧高出 5 cm。与对照组相比，健康儿童的健侧单支撑相时间高出近 4%。统计学差异具有显著性（p=0.009）。 PsA 组儿童受累下肢的摆动相时间比对照组儿童高 2.3%。统计学差异具有显著性（p=0.019）。 整体来看，对照组儿童的摆动相时间比 PsA 组儿童高近 4%。统计学差异具有显著性（p=0.019）。</p> <p>结论。具有 PsA 特征的步态模式由特定的发病机制决定，其发展机制不同于其他类型的关节炎。</p></trans-abstract><kwd-group xml:lang="en"><kwd>psoriatic arthritis</kwd><kwd>instrumental gait analysis</kwd><kwd>spatiotemporal gait parameters</kwd><kwd>kinematic gait parameters</kwd><kwd>inertial sensors</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>псориатический артрит</kwd><kwd>инструментальный анализ походки</kwd><kwd>временно-пространственные параметры походки</kwd><kwd>кинематические параметры походки</kwd><kwd>инерционные датчики</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>银屑病关节炎</kwd><kwd>仪器步态分析</kwd><kwd>时空步态参数</kwd><kwd>运动学步态参数</kwd><kwd>惯性传感器</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Skvortsov DV.
