The pilot study included 18 Russian-speaking patients diagnosed with MS. The questionnaire was completed under the supervision of a neurologist, and its clarity, accessibility of wording and overall perception by patients were assessed. The median age of the pilot study participants was 33 years, the median duration of the disease was 6 years, and the mean EDSS score was 4.0.</p></sec><sec><title>   Results</title><p>   Results. All participants successfully completed the questionnaire without difficulty. The time taken to complete it ranged from 4 to 12 minutes. Following the analysis, the final Russian-language version of the AMSQ questionnaire, adapted to take account of linguistic and cultural characteristics, was approved. The Russian-language version of the questionnaire demonstrated clinical applicability and comprehensibility for patients with MS.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. This questionnaire can be used in routine clinical practice and scientific research as a reliable tool for assessing hand function. The next stage of the validation study will involve evaluating the psychometric properties of the Russian-language version of the questionnaire.</p></sec></abstract><trans-abstract xml:lang="ru"><p>   Нарушение функции рук – одно из распространенных клинических проявлений рассеянного склероза (РС), оказывающих существенное влияние на качество жизни пациентов.</p><p>   Цель исследования – разработка русскоязычной версии и лингвокультурная адаптация опросника «Функция рук при РС» (ФРРС) / Arm Function in Multiple Sclerosis Questionnaire (AMSQ), используемого для количественной оценки функционального состояния рук у пациентов с РС.</p><sec><title>   Материал и методы</title><p>   Материал и методы. Процесс перевода и лингвокультурной адаптации опросника включал шесть этапов: прямой перевод двумя специалистами, синтез переводов, обратный перевод, экспертизу русскоязычной версии опросника, пилотное тестирование и финальную редакцию текста. В пилотное исследование были включены 18 русскоязычных пациентов с диагнозом РС. Опросник заполнялся под контролем невролога, оценивались его понятность, доступность формулировок и общее восприятие пациентами. Медиана возраста участников пилотного тестирования составила 33 года, медиана продолжительности заболевания – 6 лет, средний балл по шкале EDSS – 4,0.</p></sec><sec><title>   Результаты</title><p>   Результаты. Все участники успешно завершили заполнение опросника без затруднений. Время заполнения варьировало от 4 до 12 мин. По итогам анализа утверждена финальная русскоязычная версия опросника ФРРС, адаптированная с учетом языковых и культурных особенностей. Русскоязычная версия опросника показала клиническую применимость и понятность для пациентов с РС.</p></sec><sec><title>   Заключение</title><p>   Заключение. Данный опросник может использоваться в рутинной клинической практике и научных исследованиях как надежный инструмент для оценки функционального состояния рук. На следующем этапе исследования по валидации планируется оценка психометрических характеристик русскоязычной версии опросника.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рассеяный склероз</kwd><kwd>опросник «Функция рук при рассеяном склерозе» (ФРРС)</kwd><kwd>русская версия</kwd><kwd>лингвокультурная адаптация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiple sclerosis</kwd><kwd>the Arm Function in Multiple Sclerosis Questionnaire (AMSQ)</kwd><kwd>Russian-language version</kwd><kwd>linguistic and cultural adaptation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The investigation has not been sponsored</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">McGinley MP, Goldschmidt CH, Rae-Grant AD.
