Corrected-article in Int J Biol Sci, Volume 5, 647
We would like to make the following corrections of our paper (Int J Biol Sci 2009; 5:647-658) 1.
On Page 649, the sentence “Mckenzie in 1981 first described the centralization phenomenon, which consists of pain in the central line of the spine upon lateral movement” should be replaced by “McKenzie in 1981 first defined the centralization phenomenon as a rapid change in the location of pain from a distal or peripheral location to a more proximal or central position”.
