Abstract: Способ определения тактики коррекции функционального состояния школьников относится к медицине, точнее к выявлению ранних стадий нарушений функционального состояния школьников. Способ состоит в проведении сеансов тренировки диафрагмального дыхания с использованием биологической обратной связи по частоте сердечных сокращений (ЧСС), причем школьнику предлагают дышать, делая вдох после достижения минимального значения ЧСС на выдохе. Сначала по данным 1-2 сеансов определяют величину дыхательной аритмии (ДА) и в зависимости от ее величины и возраста школьника выставляют оценку от 5 до 1 балла. После этого проводят 5-10 сеансов тренировки и снова оценивают ДА в баллах. Если сохраняется первоначальная оценка в 5 баллов, сеансы прекращают. Если при первоначальных оценках 3-4 балла оценка сохраняется или увеличивается на 1-2 балла, сеансы продолжают до 11-15. Если при первоначальной оценке в 1-2 балла оценка увеличивается на 1-2 балла, сеансы продолжают до 16-20, а если она не меняется, сеансы приостанавливают, а школьника направляют на выявление сопутствующей патологии. После ее устранения цикл определения тактики коррекции повторяют. Способ позволяет определить такую тактику коррекции функционального состояния школьника, при которой достигается полная коррекция данного состояния.
