Abstract：Objective To systematically analyze the diagnostic methods for dysphagia caused by sarcopenia.Meth-ods Literature on sarcopenia and dysphagia in PubMed,CINAHL,Embase,Web of Science,The Cochrane Library,Medline,CNKI,Wanfang,VIP,and Chinese biomedical databases were searched until October 23,2023.A scoping re-view methodology was employed to screen,summarize,and analyze the included studies to explore relevant diagnostic methods for dysphagia secondary to sarcopenia.Results A total of 21 articles were included,identifying three diagnos-tic methods for dysphagia caused by sarcopenia,the first one was"coexistence of sarcopenia and dysphagia,excluding oth-er causes of dysphagia"(11 studies),The second was"the diagnostic consensus of dysphagia caused by sarcopenia"(one case report),the third was the diagnosis algorithm of dysphagia caused by sarcopenia(9 studies).However,the first ap-proach cannot accurately measure the quality of the swallowing muscles,making it difficult to establish a causal relation-ship between sarcopenia and dysphagia.The second method was constrained by the conditions and costs of imaging exami-nations,necessitating further development and validation of simplified indicators to replace imaging assessments of muscle quality.The third method was limited in its applicability to specific populations,highlighting an urgent need for more high-quality research to optimize its use.Conclusions Currently,there are three main diagnostic methods for dysphagia caused by sarcopenia,which should be selected based on the specific research conditions and environments.However,each method has its limitations and requires further optimization to enhance its effectiveness and applicability.
