I'm not sure what you mean by the best technique? Positional release was first developed by Lawrence Jones,DO. He called it spontaneous release by positioning( later strain counter strain). If you look at his book,it is fairly involved. It it taught by PTs and MTs around the country. Also Ortho-bionomy is a scaled down version, easier to learn,but still effective. Here is a good starter video http://www.realbodywork.com/positionalR/positionalR.htm Hope this helps.
