We performed a dynamic examination of a 4-year-old female patient after acute post hypoxia (freshwater drowning) using single-pulse magnetic stimulation, magnetic resonance tractography with reconstruction of the corticospinal tract from the primary motor cortex and supplemental area, segmentation and morphometry of brain. Post hypoxic damage in a 4-year-old child resulted not only in the loss of cortical motor evoked potentials, but also in the suppression of segmental cervical motor evoked potentials with preservation of peripheral ones. The obtained data indicate the negative effect of hypoxia on the conducting function of the proximal part of the peripheral nervous system, which probably aggravates the process of motor recovery of patients with post anoxic encephalopathy. </p></abstract><trans-abstract xml:lang="ru"><p>В статье представлен клинический случай угнетения цервикального сегментарного вызванного моторного ответа у ребенка с постаноксической энцефалопатией. Нами было проведено динамическое обследование пациентки 4 лет после перенесенного острого постаноксического состояния (утопление в пресной воде) с использованием одностимульной магнитной стимуляции, магнитно-резонансной трактографии с реконструкцией кортикоспинального тракта от первичной моторной коры и дополнительной моторной зоны, сегментацией и морфометрией головного мозга. Постаноксическое состояние у ребенка 4 лет привело не только к выпадению кортикальных вызванных моторных ответов, но и к угнетению сегментарного цервикального вызванного моторного ответа при сохранности периферического проведения. Полученные данные свидетельствуют о негативном эффекте гипоксии на проводящую функцию проксимального отдела периферической нервной системы, что, вероятно, усугубляет процесс моторного восстановления пациентов с постаноксической энцефалопатией.</p></trans-abstract><kwd-group xml:lang="en"><kwd>post anoxic encephalopathy</kwd><kwd>corticospinal tract</kwd><kwd>transcranial magnetic stimulation</kwd><kwd>motor evoked potential</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>постаноксическая энцефалопатия</kwd><kwd>кортикоспинальный тракт</kwd><kwd>транскраниальная магнитная стимуляция</kwd><kwd>вызванный моторный ответ</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Gruss M., Ettorre G., Stehr A. et al.
