Electrical muscle stimulation (EMS) is a technique that involves the use of electric currents to stimulate muscles, causing them to contract involuntarily. Primarily utilized in physical therapy to aid in the recovery process following an injury, researchers have also investigated the potential of EMS in various other domains.
Understanding Electrical Muscle Stimulation (EMS)
Electrical muscle stimulation, also known as EStim, is a non-invasive and non-pharmacological technique that works by influencing various aspects of muscle cells. This includes ion channels, proteins, and organelles, resulting in a range of interactions that ultimately impact the cells’ activity. The primary effect of EMS is to replicate the signals originating from the central nervous system, consequently leading to muscle contractions.
Through repetitive contractions induced by EMS, several benefits can be observed. Firstly, it enhances blood flow to the targeted muscles, which contributes to improved oxygen and nutrient delivery. Secondly, it aids in strengthening the muscles, thereby enhancing their overall functionality. Lastly, EMS can help slow down the process of muscle loss, which is particularly beneficial for individuals undergoing physical rehabilitation or looking to maintain muscle mass.
Critically Ill Patients
Critically ill patients face various complications, one of which is the significant loss of muscle mass. This decline in muscle mass is not only caused by the illness itself but also by the immobility that is required for patients in an intensive care unit (ICU).
A recent study focused on exploring the effects of electrical muscle stimulation (EMS) on ICU patients as a means to slow down muscle loss. The findings of this study revealed that implementing EMS during the initial week of ICU admission played a crucial role in preserving a significant amount of muscle mass. Remarkably, the benefits of EMS were not limited to the directly stimulated muscle groups, but extended to other muscle groups as well.
