Prevalence of Sarcopenia in Stroke Patients

The goal of this observational study is to analyze the characteristics of sarcopenia-related variables in post-acute and chronic stroke patients using various clinical measurement tools. The study also aims to examine the differences in these variables based on age groups (40-65 years and \>65 years), sex, and stroke severity. The main questions it aims to answer are: What are the differences in sarcopenia prevalence and related indicators between post-acute care and chronic stroke patients? How do age, sex, and stroke severity affect these sarcopenia-related measurements? Participants will include stroke patients aged 40 and older with adequate cognitive and physical function to complete sarcopenia screening and questionnaires. They will be divided into two groups: Group 1: Chronic stroke patients (n ≥ 75) Group 2: Post-acute care stroke patients (n ≥ 25) All participants will undergo both objective and subjective assessments, including: Objective assessments: Body composition, quadriceps strength, quadriceps and gastrocnemius muscle thickness via ultrasound, calf circumference, dominant hand grip strength, walking speed, SARC-F questionnaire, and the Mini Nutritional Assessment. Subjective assessment: EQ-5D health-related quality of life questionnaire. The collected data will be analyzed to compare the prevalence and characteristics of sarcopenia between the two stroke groups and across different subgroups by age and sex.
