(Dommerholt et al., 2006;
Fernandez C et al., 2005 and Malanga,
2010). Simons and Travell suggested that
trigger points in the muscle quadratus
lumborum and gluteus medius are
frequently found in low back pain. Trigger
points in the gluteus medius muscle refer
pain and tenderness along the posteriorcrest of the ilium, to the gluteal (posterior
and lateral aspect) and sacral regions
which is commonly identified as low back
pain or lumbago (Simons, 1983; Travell,
1999)
