Oxidative stress and immune system analysis after cycle ergometer use in critical patients.

Objective:: The passive cycle ergometer aims to prevent hypotrophy and improve muscle strength, with a consequent reduction in hospitalization time in the intensive care unit and functional improvement. However, its effects on oxidative stress and immune system parameters remain unknown. The aim of this study is to analyze the effects of a passive cycle ergometer on the immune system and oxidative stress in critical patients.

Effects of electrical muscle stimulation early in the quadriceps and tibialis anterior muscle of critically ill patients.

Background: Electrical muscle stimulation (EMS) is applied to critically ill patients in order to improve their muscle strength, thereby preventing hypotrophy and promoting functional recovery.

Objective: To assess the effects of early EMS on the range of movement of the ankle joint, and on thigh and leg circumference in critically ill patients.

Methods: This is a prospective randomized clinical trial comprising 11 patients undergoing mechanical ventilation.
