Objective To collect and summarize the latest relevant evidence of early muscle strength training for stroke patients at home and abroad,so as to provide a reference for the establishment of a scientific program of early muscle strength training after stroke. Methods We systematically searched in UpToDate,Joanna Briggs Institute evidence-based health care center database,National Guideline Clearinghouse,National Institute for Health and Care Excellence,Registered Nurses’ Association of Ontario,American Association of Critical-Care Nurses,National Stroke Foundation of Australia,Cochrane Library,PubMed,Web of Science,Dutch Medical Abstracts database,CNKI,Wanfang database,VIP database and Chinese biomedical literature database for all evidence on early muscle strength training for stroke patients,including guidelines,system reviews,best practice information booklets,evidence summaries,expert consensuses and original research. The retrieval time is from the establishment of the databases to October 30,2019. 2 researchers independently evaluated the quality of literature,and extracted the literature that met the standards with their professional judgment. Results A total of 18 pieces of literature were included,including 5 guidelines,1 evidence summary and 12 systematic reviews. The best evidence includes evaluation,intervention timing,intervention plan,muscle strength training interventions,quality control,effect evaluation and economic benefits. A total of 28 pieces of evidence are summarized. Conclusion We summarized the best evidence of early muscle strength training for stroke patients,and provided evidence-based references for clinical staff to carry out evidence application. It is suggested that the clinical staff should actively carry out the early muscle strength training for stroke patients in combination with the specific situation of the room,the willingness of patients and the evidence of promoting factors,obstacles and coping strategies. At the same time,the evidence should be updated dynamically to ensure the quality.
