Transcutaneous electrical nerve stimulation (TENS) devices deliver low-voltage electrical currents to the skin’s surface. While often used for pain management, the notion of such devices promoting muscle growth has gained traction. This concept suggests that electrical stimulation might mimic the signals nerves send to muscles during exercise, potentially leading to increased strength and size. For example, athletes might utilize this technology in hopes of enhancing performance or aiding recovery.
The potential benefits of electrical stimulation for muscle development are a subject of ongoing research. Proponents suggest it could offer a supplementary approach to traditional strength training, particularly for individuals with limited mobility or those recovering from injuries. Historically, electrical stimulation has been employed in physical therapy and rehabilitation settings, primarily for pain relief and restoring muscle function after injury or surgery. The exploration of its application for muscle growth represents a relatively newer area of investigation.
