Neuromuscular Electrical Stimulation in Critically Ill Patients.

Study Overview
=================
Brief Summary
-----------------
The study will investigate the effects of neuromuscular electrical stimulation (NMES) in critically ill patients. The objective of this study will be investigate the effects of neuromuscular electrical stimulation (NMES) in critically ill patients.

Detailed Description
-----------------
The study will investigate the effects of neuromuscular electrical stimulation (NMES) in critically ill patients. It will be a randomised crossover clinical trial. Thirty-one patients will enrolled. Patients will be selected, randomly, to the intervention Protocol (decubitus position with the limbs raised and NMES) and control (decubitus position with the limbs raised without NMES).The patients will be allocated in Group 1 (intervention and control) or group 2 (control and intervention) with a wash-out period of 4 to 6 hours between them. The main outcome will be metabolic data. Linear mixed model will be used for analysis of dependent variables and estimated values of the mean of the differences of each effect. The results of this study will allow better understanding of the metabolic effects of NMES in patients critically ill.
