“…In particular, different types of electrical stimulation, defined as the non-invasive transmission of electric signals into the body, have been developed. The neuromuscular electrical stimulation (NMES) is characterized by electrical impulses that are delivered to the muscle through electrodes placed on the skin that subsequently lead to muscle contraction [15]. NMES has been used for the treatment of muscle weakness by patients with prolonged hospitalization [16], in cancer rehabilitation [17], in prevention of thromboembolism [18], for motor recovery in children with neurologic conditions [19] and for the treatment of sports injuries [20] Similarly, peripheral electrical stimulation (PES) applied through electrodes have been used for the recovery from injuries, for the treatment of chronic pain and for promoting motor rehabilitation [21,22].…”
