“…The prevalence of sarcopenia in stroke patients in acute hospitals has been reported to be 8.5–33.8% [ 12 , 13 , 14 , 15 , 16 ], and sarcopenia leads to unfavorable outcomes 90 days after stroke [ 15 ]. In post-acute rehabilitation hospitals, approximately 50% of patients suffer from sarcopenia on admission [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ], and sarcopenia inhibits functional recovery and return to home in patients with stroke [ 25 ]. In addition, in several studies, pre-stroke sarcopenia was diagnosed using the SARC-F questionnaire [ 33 , 34 , 35 , 36 ], and pre-stroke sarcopenia was a predictor of functional outcome after 3 months [ 34 ].…”
