Muscle Weakness Condition

This clinical study aims to compare the effects of conventional physical therapy alone versus conventional physical therapy combined with neuromuscular electrical stimulation (NMES) in patients admitted to the ICU and undergoing invasive mechanical ventilation. Participants will be randomly assigned to receive either conventional physical therapy or the same therapy plus NMES applied to the lower limbs. The protocol includes muscle-specific stimulation parameters and safety criteria to postpone sessions in cases of clinical instability. The primary goal is to assess whether NMES improves muscle function and recovery in critically ill patients.
