Low-dose radiation therapy (LDRT) is considered a potentially effective method for refractory forms of the disease; however, data on its use using modern radiation techniques remain limited.</p> <p><bold>Purpose.</bold> To evaluate the efficacy and safety of LDRT in patients with chronic plantar fasciitis who failed standard conservative treatments.</p> <p><bold>Materials and Methods.</bold> The study included 32 patients over 40 years of age with a confirmed diagnosis of plantar fasciitis and a pain duration of ≥3 months. All patients had previously received at least two types of conservative treatment. LDRT was administered using linear accelerators and a Co-60 device at a dose rate of 0.5 Gy x up to a total dose of 3 Gy, three times weekly. Efficacy assessment included changes in pain using the Visual Analogue Scale (VAS) and functional indicators of foot mobility. Safety was assessed by the presence of early and late radiation reactions.</p> <p><bold>Results.</bold> The average pain severity on the visual analogue scale (VAS) decreased from a baseline of 6.0 (Q1-Q3: 5-7) to 3.5 (2-4) points at the end of the course and 0.5 points after 6 months (p &lt; 0.001). A significant therapeutic effect was observed in patients with significant baseline limitation of foot mobility (n=17), with complete or almost complete restoration of function observed in 77.7% of patients (n=14). Patients with mild baseline limitation of foot mobility (n=15) noted improvement in foot function in 86.7% of cases (n=13). No adverse radiation reactions were recorded.</p> <p><bold>Conclusion.</bold> LDRT has demonstrated high clinical efficacy and a favorable safety profile in patients with chronic plantar fasciitis refractory to conservative therapy. The use of modern dose delivery techniques confirms the feasibility of this approach. Further randomized studies are needed to refine optimal radiation regimens and patient selection criteria.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Плантарный фасциит является одним из наиболее распространённых дегенеративно-воспалительных заболеваний стопы, часто сопровождающимся хроническим болевым синдромом и снижением качества жизни. Низкодозная лучевая терапия (НДЛТ) рассматривается как потенциально эффективный метод при рефрактерных формах заболевания, однако данные о её применении с использованием современных техник облучения остаются ограниченными.</p> <p><bold>Цель исследования.</bold> Оценить эффективность и безопасность НДЛТ у пациентов с хроническим плантарным фасциитом, не ответивших на стандартные консервативные методы лечения.</p> <p><bold>Материалы и методы.</bold> В исследование включено 32 пациента старше 40 лет с подтверждённым диагнозом плантарного фасциита и длительностью болевого синдрома ≥3 месяцев. Все пациенты ранее получали как минимум два вида консервативного лечения. НДЛТ проводилась на линейных ускорителях и аппарате Co-60 в режиме 0,5 Гр × до суммарной дозы 3 Гр, три раза в неделю. Оценка эффективности включала динамику болевого синдрома по ВАШ и функциональные показатели подвижности стопы, безопасность оценивалась по наличию ранних и поздних лучевых реакций.</p> <p><bold>Результаты.</bold> Средняя выраженность боли по визуально-аналоговой шкале (ВАШ) снизилась с исходных 6,0 (Q1-Q3: 5-7) до 3,5 (2-4) баллов на момент завершения курса и 0,5 балла через 6 месяцев (p &lt;0,001). Выраженный терапевтический эффект отмечался у пациентов с исходно значительной ограниченностью подвижности стопы (n=17), где полное или почти полное восстановление функции наблюдалось у 77,7% пациентов (n=14). Пациенты с незначительной исходной ограниченностью стопы (n=15) отмечали улучшение функции стопы в 86,7% случаев (n=13). Нежелательных лучевых реакций не зарегистрировано.</p> <p><bold>Выводы.</bold> НДЛТ продемонстрировала высокую клиническую эффективность и благоприятный профиль безопасности у пациентов с хроническим плантарным фасциитом, рефрактерным к консервативной терапии. Применение современных методик подведения дозы подтверждает практическую осуществимость подхода. Требуются дальнейшие рандомизированные исследования для уточнения оптимальных режимов облучения и критериев отбора пациентов.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>plantar fasciitis, heel spur, radiation therapy, non-neoplastic radiation therapy, low-dose irradiation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>плантарный фасциит, пяточная шпора, лучевая терапия, лучевая терапия неопухолевых заболеваний, низкодозное облучение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
