Abstract:

Objective To search，evaluate，and summarize the relevant evidence of blood flow restriction training in elderly patients with sarcopenia，and provide references for medical staff to guide elderly patients to carry out blood flow restriction training to prevent and treat sarcopenia. Methods Computer systems were used to search domestic and foreign databases，relevant guide websites，and professional association websites for guidelines，expert consensuses，expert opinions，clinical decisions，system reviews，recommended practice，and evidence summaries on blood flow restriction training for elderly patients with sarcopenia. The retrieval period was from the inception of databases to March 2023. There were 2 researchers who independently conducted literature quality evaluation，evidence extraction，and integration. Results A total of 14 articles were finally included，including 1 guideline，12 systematic reviews，and 1 expert opinion. A total of 27 pieces of best evidence were summarized from 7 aspects：exercise assessment，exercise mode，pressure parameters，exercise parameters，exercise effects，exercise safety，and evaluation methods. Conclusion This study summarized the best evidence for blood flow restriction training in elderly patients with sarcopenia. It is recommended that medical staff fully consider clinical practice when applying evidence，and develop personalized blood flow restriction training programs based on the exercise preferences and actual situations of the elderly to prevent and treat sarcopenia.
