Rehabilitation of Critically Ill Patients With SARS-CoV-2 Variants in ICU With Limited Resources

Patients in both groups received the functional rehabilitation protocol adapted from the precoce mobilization protocol of Morris et al, 2008. The protocol was defined in 5 stages, with a period between the application of the stages according to the clinical conditions of the patient, in an interval maximum of 24 hours from the beginning of the application of the first stage. The steps included active assisted mobilization exercises, active with Proprioceptive Neuromuscular Facilitation (PNF) method diagonals for upper limbs and bridge exercises, bedside sitting, balance reactions, weight bearing, transfer to an armchair, passive and active orthostatism, static gait and ambulation. The experimental group also received a protocol of neuromuscular electrical stimulation (NMES), applied bilaterally for 30 minutes, using an electrical stimulator with rectangular pulse waves, symmetrical biphasic, applied to the quadriceps femoris and tibialis anterior muscle at the best motor point, activating fast fibers with a pulse time of less than 300 ms and slow pulses with a pulse time of more than 300 ms, with intensity adjusted to obtain visible muscle contraction and/or according to the patient's tolerance.
