An updated systematic review and meta-analysis of 16 high-quality randomized trials (2,385 ICU patients) delivers a clear verdict: starting mobilization within 72 hours of admission is not only safe but powerfully effective.

Early mobilization (EM) significantly shortens both ICU length of stay and duration of mechanical ventilation, while markedly improving muscle strength and functional independence at hospital discharge. Crucially, it does so without increasing adverse events or mortality compared to standard care.

These robust findings cement EM as a low-risk, high-reward intervention that should be standard practice in intensive care units worldwide, offering faster recovery, lower costs, and better patient outcomes—though longer-term impacts on survival and quality of life still await confirmation in larger studies.
