Secondary objectives~To assess the performance of the SARC-F questionnaire to screen for sarcopenia ;~To describe the characteristics of sarcopenic patients hospitalized in each follow-up care and rehabilitation unit (i.e. day hospital, full hospitalization);~To identify predictive factors of sarcopenia;~To determine, in the subgroup of patients hospitalized in the conventional follow-up care and rehabilitation unit (i.e. full hospitalization), the evolution of sarcopenia between admission and discharge of the following variables :~muscle strength,~muscle mass,~functional ability,~dependency.~Conduct of research~After receiving the written consent of the study participant, all of the following tests and questionnaires will be performed :~SARC-F questionnaire,~measurement of muscle strengh by a grip test,~measurement of muscle mass by impedancemetry (ASM/size2),~4-meter walking speed test,~Timed-Up and Go (TUG) test,~ADL (Activities of Daily Living) and IADL (Instrumental Activities of Daily Living) questionnaires.~For patients in day hospital care, the study will end upon completion of these tests.~For patients hospitalized in the conventional follow-up care and rehabilitation unit (i.e. full hospitalization), a follow-up visit will be scheduled within 72 hours prior to the patient's discharge from the service, or at 3 months of hospitalization. The following tests and questionnaires will be performed during this visit:~measurement of muscle strengh by a grip test,~measurement of muscle mass by impedancemetry,~4-meter walking speed test,~Timed Up and Go (TUG) test,~ADL and IADL questionnaires.
The main objective of this study is to determine the prevalence of sarcopenia in patients hospitalized in the follow-up care and rehabilitation units of the geriatrics department of the Mulhouse French hospital.
