However, despite its proven clinical efficacy, the optimal scope of medical rehabilitation required to maximize functional outcomes and quality of life remains unclear.</p> <p><bold>AIM:</bold><italic> </italic>This study aimed to assess the efficacy of a specialized medical rehabilitation program after reverse shoulder arthroplasty based on modern techniques, including isokinetic dynamometry and biofeedback training.</p> <p><bold>METHODS:</bold><italic> </italic>A comparative cohort study was conducted in 33 patients with omarthrosis who underwent reverse shoulder arthroplasty. The patients were divided into two groups. The treatment group (<italic>n</italic> = 17) underwent a structured rehabilitation program developed by the authors, whereas the control group (<italic>n</italic> = 16) did not receive organized rehabilitation. The primary endpoint was recovery of shoulder joint function, including range of motion, muscle strength, coordination, and patient-reported quality of life. Assessment methods included goniometry, isokinetic dynamometry, evaluation of complex coordinated movement abilities, volumetric analysis of upper limb motion using a spherical motion sector, and patient questionnaires (DASH, PSS, SF-36).</p> <p><bold>RESULTS:</bold><italic> </italic>Patients who underwent the medical rehabilitation program had significantly better functional outcomes than the control group. Abduction range was 150° [150°–160°] in the treatment group vs. 107.5° [93.75°–140°] in the control group (<italic>p</italic> &lt; 0.001). Flexion range was 160° [150°–165°] in the treatment group vs. 120° [107.5°–133.8°] in the control group (<italic>p</italic> &lt; 0.001). External rotation range was also greater in the treatment group: 45° [40°–55°] vs. 25° [20°–36.3°], <italic>p</italic> &lt; 0.001. Abduction strength reached 23.6 Nm [19.3–32.4] in the treatment group vs. 16.7 Nm [9.93–20.6] in the control group (<italic>p</italic> = 0.005). The spherical motion sector volume in the treatment group was 230,778 cm³ [207,921–268,565], exceeding that of the control group: 126,952 cm³ [107,894.25–151,971.3], <italic>p</italic> = 0.001. Correlation analysis revealed a strong positive relationship between shoulder joint range of motion and coordination parameters (r = 0.78, <italic>p</italic> &lt; 0.001), as well as muscle strength (r = 0.71, <italic>p</italic> &lt; 0.001). Moreover, higher patient-reported satisfaction scores (SF-36) were associated with increased muscle strength and greater external rotation range (r = 0.63, <italic>p</italic> = 0.002).</p> <p><bold>CONCLUSION:</bold> Implementing a comprehensive, personalized rehabilitation program after shoulder arthroplasty significantly improves functional outcomes. Optimized medical rehabilitation programs will improve the quality of medical care and long-term clinical outcomes in patients following reverse shoulder arthroplasty.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Реверсивное эндопротезирование плечевого сустава является эффективным методом хирургического лечения тяжёлых дегенеративных и посттравматических патологий плечевого сустава. Однако, несмотря на доказанную клиническую эффективность, остаётся открытым вопрос о выборе оптимального объёма медицинской реабилитации, способного максимизировать функциональные результаты и качество жизни пациентов.</p> <p><bold>Цель.</bold> Оценить эффективность специализированной программы медицинской реабилитации после реверсивного эндопротезирования плечевого сустава, основанной на применении современных методик, включая изокинетическую динамометрию, и тренировок с биологической обратной связью.</p> <p><bold>Материалы</bold><bold> </bold><bold>и</bold><bold> </bold><bold>методы.</bold> Проведено когортное сравнительное исследование, включавшее 33 пациента с диагнозом «омартроз», перенёсших реверсивное эндопротезирование плечевого сустава. Пациенты были разделены на две группы: основная группа (<italic>n</italic>=17) проходила структурированную программу медицинской реабилитации по разработанной методике, а контрольная (<italic>n</italic>=16) характеризовалась отсутствием организованной реабилитации. Первичной конечной точкой исследования являлось восстановление функциональных показателей плечевого сустава, включая амплитуду движений, силу мышц, координационные способности и субъективные показатели качества жизни. Методы оценки включали гониометрию, изокинетическую динамометрию, анализ способности выполнять сложнокоординированные движения, шарового сектора движений верхней конечности и анкетирование (DASH, PSS, SF-36).</p> <p><bold>Результаты.</bold> Пациенты, прошедшие курс медицинской реабилитации, продемонстрировали статистически значимо лучшие функциональные показатели по сравнению с контрольной группой. Амплитуда отведения составила 150° [150°–160°] в основной группе против 107,5° [93,75°–140°] в контрольной (<italic>p</italic> &lt;0,001). Амплитуда сгибания составила 160° [150°–165°] в основной группе против 120° [107,5°–133,8°] в контрольной (<italic>p</italic> &lt;0,001). Амплитуда наружной ротации также была выше в основной группе (45° [40°–55°] против 25° [20°–36,3°] в контрольной (<italic>p</italic> &lt;0,001). Сила отведения в основной группе достигала 23,6 Нм [19,3–32,4], тогда как в контрольной — 16,7 Нм [9,93–20,6] (<italic>p</italic>=0,005). Шаровой сектор движений в основной группе составил 230 778 см³ [207 921–268 565], что превышало показатели контрольной группы — 126 952 см³ [107 894,25–151 971,3], <italic>p</italic>=0,001. Анализ корреляционных связей показал, что объём движений в плечевом суставе имел сильную положительную корреляцию с координационными показателями (r=0,78, <italic>p</italic> &lt;0,001) и силой мышц (r=0,71, <italic>p</italic> &lt;0,001). Кроме того, высокие показатели субъективной удовлетворённости пациентов (опросник SF-36) были ассоциированы с улучшением силы мышц и амплитуды наружной ротации (r=0,63, <italic>p</italic>=0,002).</p> <p><bold>Заключение.</bold> Применение комплексной персонализированной программы реабилитации после артропластики плечевого сустава способствует значительному улучшению его функциональных показателей. Оптимизация программ медицинской реабилитации позволит повысить качество медицинской помощи и улучшить долгосрочные клинические исходы у пациентов после реверсивного эндопротезирования плечевого сустава.</p></trans-abstract><kwd-group xml:lang="en"><kwd>reverse shoulder arthroplasty</kwd><kwd>medical rehabilitation</kwd><kwd>biofeedback</kwd><kwd>isokinetic dynamometry</kwd><kwd>range of motion</kwd><kwd>muscle strength</kwd><kwd>motor coordination</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>реверсивное эндопротезирование плечевого сустава</kwd><kwd>медицинская реабилитация</kwd><kwd>биологическая обратная связь</kwd><kwd>изокинетическая динамометрия</kwd><kwd>амплитуда движений</kwd><kwd>сила мышц</kwd><kwd>координация движений</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kesyan GA, Karapetyan GS, Shuyskiy AA, et al.
