Physical rehabilitation is recommended to address the physical and functional deficits associated with ICU-AW, and delivery is advocated across the continuum of the patient recovery pathway, commencing whilst in the ICU, following transfer to the ward and beyond hospital discharge. Physical rehabilitation within the ICU typically incorporates early mobilisation (EM), characterised by a hierarchical progression of increasingly functional activities such as active-assisted bed exercises, sitting-on-the-edge-of-the-bed (SOEOB), standing, marching-on-the-spot and walking. These activities are summarised in the ICU Mobility Scale. In recent years, adjunctive technologies including electrical muscle stimulation, interactive video-games and passive cycle ergometry have also been utilised.
