“…The existing scientific basis regarding the use of TENS in wound healing is more evident for chronic wounds initiated or aggravated by diseases such as diabetes (15), leprosy (16), peripheral arterial insufficiency (6,22), chronic venous insufficiency (19 -21) and in pressure ulcers in patients with spinal cord injuries (17,18). Considering acute wounds, animal studies have demonstrated that low-frequency TENS optimized the healing of burn lesions in elderly rats (10), improved healing by increasing growth factors in the dermis and epidermis (13) and reduced proinflammatory cytokines in the dermis by inhibiting the inflammatory phase, promoting a decrease in the duration of the cicatrization process (23).…”
