The purpose of this study is to investigate whether grip strength can be used as an indicator of swallowing function. The results showed that grip strength assessment based on the criteria for sarcopenia can be a useful tool for estimating swallowing function.
The purpose of this study is to clarify whether swallowing function can be inferred from grip strength. Based on the diagnostic criteria of sarcopenia, patients were divided into two groups according to grip strength, and it was analyzed whether there was a difference in the evaluation index for swallowing function between the two groups. Among the cases requesting evaluation of swallowing function from June 10, 2020 to October 28, 2020, 83 cases (mean age: 71.7 years, 59 males and 24 females) who received assessment tests and swallowing endoscopy were included. According to the diagnostic criteria for grip strength in the Asian working group in Sarcopenia, less than 28 kgf and 18 kgf were defined as the weak group for men and women, respectively. Hyodo scores, repeated salivary swallowing tests (RSST), maximum vocalization time (MPT), and dysphagia severity classification (DSS) were compared between the two groups. Of the 83 patients, 29 and 54 were in the normal group and weak group, respectively. In all indicators, the normal group showed significantly better results than the weak group: Hyodo score (2.4 vs. 4.0, p < 0.01), RSST (4.1 times vs. 2.4 times, p < 0.01), MPT (12.1 s vs. 5.9 s, p < 0.001), DSS (4.5 vs. 5.9, p < 0.001), respectively. In multiple regression analysis with DSS as the dependent variable, grip strength was a significant independent variable of DSS even after adjusting for age, gender, and body mass index. Grip strength assessment based on sarcopenia criteria can be a useful tool for estimating swallowing function.
