Grip strength as a predictor for home discharge in convalescent rehabilitation patients

[Purpose] We examined the impact of the assessment items for sarcopenia on discharge destination in convalescent rehabilitation patients. [Participants and Methods] In this study, 174 patients (males; 77, mean age; 72.4 years, females; 97, mean age; 80.1 years) who were admitted and discharged from the convalescent rehabilitation wards of the International University of Health and Welfare, Shioya Hospital, were included. The participants' height, weight, grip strength, and lower calf circumference were measured. Additionally, the number of motor functional independence measure (mFIM) at discharge, length of stay in the wards, and average number of rehabilitation sessions per day were calculated as the convalescent rehabilitation wards index. [Results] Age, weight, grip strength, lower calf circumference, mFIM at discharge, length of stay in the wards, and average number of rehabilitation sessions per day had significant differences between the return-to-home and non-home groups. Binomial logistic regression analysis revealed significant differences in grip strength and mFIM at discharge. [Conclusion] This study adjusted the sarcopenia criteria for sex and age and showed that grip strength significantly affected the outcome destination. Grip strength was shown to be a predictor of home discharge in convalescent rehabilitation patients.
