[Effects of linear polarized light irradiation around the lumbar sympathetic ganglion area upon the skin temperature of lower extremities].

Background: The effect of linear polarized light irradiation around the lumbar sympathetic ganglion area upon the skin temperature of legs may be similar to that of irradiation of near stellate ganglion area upon arms.

Methods: Linear polarized light irradiation was induced with SUPER LIZER (Tokyo Iken, Tokyo, Japan). The C probe of SUPER LIZER was placed on the left side of the supine at the level of L2.
