According to the recently proposed diagnostic criteria for sarcopenic dysphagia, sarcopenic dysphagia can be classified as probable or possible based on tongue pressure. However, it is unclear whether patients with probable and possible sarcopenic dysphagia have different characteristics. Therefore, this study aimed to investigate whether patients with possible and probable sarcopenic dysphagia have different clinical characteristics.
A cross-sectional study.
A rehabilitation hospital.
In total, 129 patients aged ≥65 years with sarcopenic dysphagia were included.
A tongue pressure of <20 kPa was indicative of probable sarcopenic dysphagia, and a tongue pressure of ≥20 kPa was indicative of possible sarcopenic dysphagia. Kuchi-Kara Taberu (KT) index scores were compared between the probable or possible sarcopenic dysphagia groups.
According to the tongue pressure, 76 and 53 patients were classified into the probable and possible sarcopenic dysphagia groups, respectively. In multiple linear regression analysis, the presence of probable sarcopenic dysphagia was independently associated with the total KT index score (standardized coefficient: -0.313, regression coefficient: -4.500, 95% confidence interval [CI], -6.920 to -2.080, P < 0.001). The presence of probable sarcopenic dysphagia was independently associated with some subitems of the KT index (willingness to eat, cognitive function while eating, oral preparatory and propulsive phase, severity of pharyngeal dysphagia, eating behavior, and daily living activities).
Patients with probable sarcopenic dysphagia were characterized by poor overall eating-related conditions, especially poor swallowing ability, ability to perform activities of daily living, and nutritional status.
根据最近提出的肌少性吞咽困难诊断标准，肌少性吞咽困难可根据舌压分为可能或很可能。然而，尚不清楚可能和很可能的肌少性吞咽困难患者是否具有不同的特征。因此，本研究旨在探讨可能和很可能的肌少性吞咽困难患者是否具有不同的临床特征。
横断面研究。
一家康复医院。
共纳入 129 名年龄≥65 岁的肌少性吞咽困难患者。
舌压＜20 kPa 提示很可能的肌少性吞咽困难，舌压≥20 kPa 提示可能的肌少性吞咽困难。比较可能或很可能的肌少性吞咽困难患者的口部进食能力（Kuchi-Kara Taberu，KT）指数评分。
根据舌压，76 例和 53 例患者分别被归类为很可能和可能的肌少性吞咽困难组。在多元线性回归分析中，很可能的肌少性吞咽困难与总 KT 指数评分独立相关（标准化系数：-0.313，回归系数：-4.500，95%置信区间[CI]：-6.920 至-2.080，P＜0.001）。很可能的肌少性吞咽困难与 KT 指数的一些亚项独立相关（进食意愿、进食时认知功能、口腔预备和推进阶段、咽部吞咽困难严重程度、进食行为和日常生活活动）。
很可能的肌少性吞咽困难患者的整体进食相关状况较差，尤其是吞咽能力、日常生活活动能力和营养状况较差。
