Background & Evidence

Electrostimulation refers to the application of electrical current through electrodes placed on the skin near a wound and includes modalities such as low-intensity direct current (LIDC), high-voltage pulsed current (HVPC), alternating current (AC), and transcutaneous electrical nerve stimulation (TENS). Electromagnetic therapy is a related but distinct treatment that applies electromagnetic fields rather than direct electrical current. Conventional wound care (standard therapy) includes local wound care and systemic measures such as debridement, wound cleansing, dressings that promote a moist wound environment, antibiotics, optimization of nutrition, and offloading/avoidance of weight-bearing.
