“…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]. Transcutaneous electrical nerve stimulation (TENS), which runs at one mA have been also tested primarily as treatments of pain [23][24][25], but may also improve sensomotoric impairments that are evident in terms of vibration perception, balance control and gait [23,24].…”
