The evidence available indicates that LIC appear to accelerate wound healing. Regarding the selection of intensity, LIDC (continuous or pulsed) appears to be effective in the range of 200 to 800 μA, and polarity may or may not be reversed. Further research is required to elucidate the effect of LIC on wound healing.
