Assessing rehabilitation effectiveness for persistent symptoms post-infection with emerging viral respiratory diseases. Systematic review of seven databases (MEDLINE, EMBASE, Cochrane Library, PEDro, MedRxiv, CNKI, Wanfang) until 30 December 2023. Evaluated 101 studies (9593 participants) on respiratory function, exercise capacity, and quality of life. Methodological quality was assessed using the Cochrane Collaboration’s Risk of Bias tool for randomized controlled trials (RCTs), the Newcastle-Ottawa Scale (NOS) for observational studies and non-RCTs, and the NIH Quality Assessment Tools for before-after studies. The most common rehabilitation program combined breathing exercises with aerobic exercise or strength training. Rehabilitation interventions significantly enhanced respiratory function, as evidenced by improvements on the Borg Scale (MD, -1. 85; 95% CI, -3. 00 to -0. 70, low certainty), the mMRC Dyspnea Scale (MD, -0. 45; 95% CI, -0. 72 to -0. 18, low certainty), and the Multidimensional Dyspnoea-12 Scale (MD, -4. 64; 95% CI, -6. 54 to -2. 74, moderate certainty). Exercise capacity also improved, demonstrated by results from the Six-Minute Walk Test (MD, 38. 18; 95% CI, 25. 33-51. 03, moderate certainty) and the Sit-to-Stand Test (MD, 3. 04; 95% CI, 1. 07-5. 01, low certainty). Rehabilitation interventions are promising for survivors of viral respiratory diseases, yet gaps in research remain. Future investigations should focus on personalizing rehabilitation efforts, utilizing remote technology-assisted programs, improving research quality, and identifying specific subgroups for customized rehabilitation strategies to achieve the best outcomes for survivors.
