Qualität von Internetvideos aus Festlandchina zur Bewegungstherapie bei ankylosierender Spondylitis

Inhaltliche Analyse



The aim of this study is to assess the quality and reliability of online videos on ankylosing spondylitis (AS) exercises from the five most popular video websites in China.


Cross-sectional and descriptive study.


We searched the video websites of Youku, Tencent, Tudou, IQiYi, and bilibili on February 15, 2020, using the keywords “Ankylosing spondylitis exercise” “Ankylosing spondylitis rehabilitation” and “Ankylosing spondylitis therapy” A total of 114 videos were included in the study and evaluated according to the Global Quality Scale (GQS) and modified DISCERN tool.


According to the GQS, the videos were classified as high quality (12.3%, n = 14), intermediate quality (63.2%, n = 72), and low quality (24.6%, n = 28). Using the modified DISCERN tool, the videos were divided into useless (53.5%, n = 61), useful (35.1%, n = 40), and misleading (11.4%, n = 13).


The analysis shows that the quality and reliability of online videos related to exercise therapy for Ankylosing spondylitis (AS) should be improved and supervised in China. Hospitals, universities, and medical doctors should make more useful and high-quality videos to provide effective exercise guidance for AS patients.



Ziel der hier vorliegenden Studie war es, die Qualität und Reliabilität von Online-Videos zu Bewegungsübungen bei ankylosierender Spondylitis (AS) von den 5 in China am meisten verbreiteten Video-Websites zu beurteilen.


Es handelt sich um eine deskriptive Studie im Querschnittdesign.


Die Autoren durchsuchten die Video-Websites von Youku, Tencent, Tudou und IQiYi sowie Bilibili am 15. Februar 2020 unter Verwendung der Schlüsselwörter „ankylosing spondylitis exercise“, „ankylosing spondylitis rehabilitation“ und „ankylosing spondylitis therapy“. Es wurden 114 Videos in die Studie einbezogen und anhand der Global Quality Scale (GQS) sowie mit dem modifizierten DISCERN-Fragebogen beurteilt.


Gemäß GQS wurden die Videos als von hoher Qualität (12,3%; n = 14), mittlerer Qualität (63,2%; n = 72) und geringer Qualität (24,6%; n = 28) eingestuft. Anhand des DISCERN-Fragebogens wurden die Videos in nutzlos (53,5%; n = 61), nützlich (35,1%; n = 40) und irreführend (11,4%; n = 13) eingeteilt.


Die Auswertung zeigt, dass in China die Qualität und Reliabilität von Online-Videos zur Bewegungstherapie bei AS verbessert und überprüft werden sollten. Krankenhäuser, Universitäten und Ärzte sollten Videos mit größerem Nutzen und von hoher Qualität entwickeln, um so eine effektive Übungsanleitung für AS-Patienten zur Verfügung zu stellen.
