Possible cause for low back pain.
The lower cross syndrome is an agonist-antagonist-synergy loss in a characteristic, predictable pattern. Some muscles become tight other muscles become weak.
The pattern forms an X or a cross when viewed laterally.
The pelvis area projects more anterior.
Psoas and erector spinae are short; abdominals and gluteus maximus are weak.
Tensor fascia latae are also short and tight, as well as piriformis, quadratus lumborum, hamstrings and latissimus dorsi.
The pattern is seen with or without complaints.
The eventual complaints can be various:
• Low back pain.
• Neck and shoulder pain.
• Rotator cuff syndrome.
• Loss of lumbar range of motion.
• Thoracolumbar pain.
