The relative effectiveness of manipulation with and without the crac technique applied to the hamstring muscles in the treatment of sacroiliac syndrome

Abstract

Sacroiliac syndrome is a common condition causing low back pain (Mierau et al. 1984, Guo and Zhao 1994). It is a painful, debilitating condition that may cause considerable discomfort (Haldeman 1992:220). According to Frymoyer et al. (1991:2114), sacroiliac syndrome is a frequently overlooked source of low back pain as it may mimic other well known causes of low back pain
