“…Several studies have reported various physiological or functional outcomes from SIJ manipulation such as reduction in muscle inhibition (Suter et al, 1999;Suter et al, 2000), electromyographic neuromuscular reflex response (Herzog et al, 1999;Colloca and Keller, 2001), decreased Hoffman reflex (Murphy et al, 1995), improved gait symmetry (Herzog et al, 1991), improved innominate bone tilt (Cibulka et al, 1988), and decreased pain and functional disability (Shearar et al, 2005). However, few clinical studies have evaluated the effectiveness of SIJ manipulation (Osterbauer et al, 1993).…”
