Abstract:Objective To construct an evidence map of Intradialytic Exercise (IDE) for Maintenance Hemodialysis (MHD) patients, so as to provide a reference for clinical practice and developing related guidelines. Methods A systematic search was conducted in domestic and international databases from database inception to November 1, 2024, and systematic reviews and meta-analyses focusing on IDE in patients with MHD were included.The methodological quality of the included studies was assessed using AMSTAR-2, and a data extraction table was developed based on the generation and reporting of evidence mappings.Bubble plots were generated using the online evidence mapping tool provided by Pymeta.com. Results A total of 33 studies were included, of which 32 concluded that IDE was "beneficial" or "possibly beneficial", and 1 study reported an "uncertain" conclusion.Approximately 30% of the studies were rated as high quality, while 70% were of low quality.The included studies primarily involved five types of exercise interventions:intra-dialytic aerobic exercise, resistance training, neuromuscular electrical stimulation, respiratory muscle training, and combined aerobic and resistance exercise.A total of 58 outcome indicators were identified, with the most frequently reported being the physical component score and mental component score of the Short Form-36 Health Survey, dialysis adequacy (Kt/V and URR), the 6-Minute Walk Test, and peak oxygen uptake. Conclusion IDE has been shown to have positive benefits for patients undergoing MHD.It is recommended that IDE be incorporated into routine nursing care to improve patients′ quality of life.
