The Symmetry’s ability to put the body in correct full upright weight bearing and achieve mild hyperextension at the hips while reducing the negative effects of shear is unique to standing systems and is the key to correct standing. This allows adjustment of the standing position for maximum stretch and a progressive standing program. This achievement has evolved through the Symmetry’s unique design principles.
