The aim of Re-Walk-Easy is to evaluate the effects of rehabilitation based on electrical stimulation on the motor performance of critically ill patients. The study will also investigate the pathophysiology of the two forms-the myopathic-predominant and the polyneuropathic-predominant variants-by examining the longitudinal progression of CIP and CIM and determining which form benefits more from electrical stimulation as a rehabilitative approach.
Although rehabilitation is often recommended to patients with Intensive Care Unit Acquired Weakness (ICU-AW) to counteract the induced muscle weakness, systematic reviews failed to determine its efficacy. Neuro Muscular Electrical Stimulation (NMES) is part of clinical practice in ICU-AW however its effects are still under debate. The investigators hypothesize that this uncertainty stems from the lack of distinction between the two forms of the condition-Critical Illness Polyneuropathy (CIP) and Critical Illness Myopathy (CIM)-which have distinct pathological features and disease trajectories. In addition, the investigators hypothesize that motivating patients by requiring voluntary muscle activation during the Electrical Stimulation (i.e. Functional Electrical Stimulation - FES) will enhance rehabilitation.
The study will test the following hypothesis through a longitudinal clinical trial aimed at determining:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| CIP-FES | Experimental | Each subject will receive 15 individual rehabilitation sessions, each lasting 60 minutes, conducted 3 to 5 times per week over a period of 5 to 3 weeks, depending on the weekly frequency, Intentional, repetitive movements, such as lower limb movements within goal-oriented mobility tasks, will be performed, with FES applied in parallel. Two approaches will be used: (i) assistive stimulation for passive patients with poor muscle strength, and (ii) proportional active stimulation for subjects with residual muscle strength. |

| Walking velocity on 10 meters walking test | Walking speed is measured by the timed 10-meter Walk Test (10MWT). Participants walk a distance of 10 meters at their usual speed with their usual walking aids. Participants are timed while walking 10 meters from a starting point to an end point. Time taken from meter 2 to meter 8. Two repetitions are completed and the average time is used to calculate walking speed in metres/second. During the test, EMG and kinematic data will be recorded using EMG-sensors and three IMUs, two placed on the feet and one on the lower back. |
