Изучение ортопедических матрасов в этом контексте может быть перспективным направлением. Цель работы. Оценить влияние ортопедических матрасов на выраженность болевого синдрома и качество сна. Материал и методы. В сентябре–декабре 2023 г. мы провели рандомизированное контролируемое исследование, в котором приняли участие добровольцы с хронической болью в пояснице. Участники были рандомизированы в 4 группы: 3 — использующие ортопедические матрасы разной степени жесткости (твердый, средний и мягкий) и 1 — контрольную (с неортопедическим матрасом). Наблюдение проводилось 4 нед. путем оценки участниками выраженности боли и качества сна по визуальной аналоговой шкале и анкете качества сна. Результаты. По результатам скрининга 117 добровольцев 86 человек были включены в исследование и рандомизированы. Впоследствии 5 человек отказались от участия, 81 участник завершил наблюдение: 21 — в группе с твердым матрасом, 20 — в группе со средним, 20 — в группе с мягким и 20 — в контрольной группе. Группы не различались по характеристикам участников. По окончании наблюдения статистически значимое снижение интенсивности боли отмечалось в каждой группе (p &lt; 0,001), а значительное улучшение качества сна наблюдалось в 3 экспериментальных (p &lt; 0,001), но не в контрольной группе (p = 0,101). Заключение. Использование ортопедических матрасов в течение 4 недель достоверно снизило боль в пояснице и улучшило качество сна.</p></abstract><trans-abstract xml:lang="en"><p>Currently, there is insufficient research on the optimal sleep surface to improve sleep quality and reduce lower back pain. Studying orthopedic mattresses in this context could be a promising direction. Objective: To assess the impact of orthopedic mattresses on pain severity and sleep quality. Materials and Methods: From September to December 2023, we conducted a randomized controlled trial involving volunteers with chronic lower back pain. Participants were randomized into 4 groups: 3 using orthopedic mattresses of varying firmness (firm, medium, and soft) and 1 control group (with a non-orthopedic mattress). Observations were made over 4 weeks, assessing pain intensity and sleep quality through a visual analog scale and sleep quality questionnaire. Results: Out of 117 screened volunteers, 86 were included, and 5 withdrew, leaving 81 participants: 21 in the firm group, 20 in the medium, 20 in the soft, and 20 in the control group. No differences were found in participant characteristics. Significant pain reduction was noted in all groups (p &lt; 0.001), with considerable sleep quality improvement in the 3 experimental groups (p &lt; 0.001) but not in the control (p = 0.101). Conclusion: Using orthopedic mattresses for 4 weeks significantly reduced lower back pain and improved sleep quality.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>боль в спине</kwd><kwd>боль в пояснице</kwd><kwd>болевой синдром</kwd><kwd>матрас</kwd><kwd>ортопедический матрас</kwd><kwd>сон</kwd><kwd>качество сна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>back pain</kwd><kwd>lower back pain</kwd><kwd>pain syndrome</kwd><kwd>mattress</kwd><kwd>orthopedic mattress</kwd><kwd>sleep</kwd><kwd>sleep quality</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке группы компаний Askona Life Group (г.
