Background The aim of this meta‐analysis was to assess if early mobilization and rehabilitation in the intensive care unit (ICU) could reduce ICU‐acquired weakness (ICU‐AW), improve functional recovery, improve muscle strength, shorten the length of ICU and hospital stays, and reduce the mortality rate. Methods A comprehensive literature search in PubMed, Embase, Web of Science, SinoMed (Chinese BioMedical Literature Service System, China), and National Knowledge Infrastructure, China (CNKI) was performed. Results were expressed as a risk ratio (RR) with 95% confidence intervals (95% CIs) or weight mean difference (WMD) with 95% CIs. Pooled estimates were calculated using a fixed‐effects or random‐effects model according to the heterogeneity among studies. Results Fifteen randomized controlled trials involving a total of 1941 patients were included in this meta‐analysis. Pooled estimates suggested that early mobilization significantly reduced the incidence of ICU‐AW (RR = 0.49, 95% CI: 0.26, 0.91; P = .025), shortened the length of ICU (WMD = −1.82 days, 95% CI: −2.88, −0.76; P = .001) and hospital (WMD = −3.90 days, 95% CI: −5.94, −1.85; P < .001) stays, and improved the Medical Research Council score (WMD = 4.47, 95% CI: 1.43, 7.52; P = .004) and Barthel Index score at hospital discharge (WMD = 21.44, 95% CI: 10.97, 31.91; P < .001). Moreover, early mobilization also decreased complications such as deep vein thrombosis (RR = 0.16, 95% CI: 0.04, 0.59; P = .006), ventilator‐associated pneumonia (RR = 0.26, 95% CI: 0.11, 0.63; P = .003), and pressure sores (RR = 0.14, 95% CI: 0.04, 0.44; P = .001). However, early mobilization did not reduce the ICU mortality rate (RR = 1.31, 95% CI: 0.97, 1.76; P = .074), improve the handgrip strength (WMD = 4.03 kg, 95% CI: −0.68, 8.74; P = .094), and shorten the duration of mechanical ventilation (WMD = 0.20 days, 95% CI: −0.10, 0.50; P = .194). Conclusion This study indicated that early mobilization was effective in preventing the occurrence of ICU‐AW, shortening the length of ICU and hospital stay, and improving the functional mobility. However, it had no effect on the ICU mortality rate and ventilator‐free days. Relevance to clinical practice ICU‐AW is a common neuromuscular complication of critical illness, and it is predictive of adverse outcomes. Early mobilization of critically ill patients is a candidate intervention to reduce the incidence and severity of ICU‐AW. Some clinical studies have demonstrated this, whereas others found opposite results. The aim of our study is to assess if early mobilization and rehabilitation in the ICU could reduce the ICU‐AW, improve functional recovery, improve muscle strength, shorten length of ICU and hospital stay, and reduce the mortality rate.
