Lower cross syndrome is named for the crossing tightness and weakness that occurs in the lower back, core, and hip muscles. In LCS, tightness of the low back muscles crosses with tightness of the iliopsoas (hip flexors) and rectus femoris (main quad muscle). Weakness of the deep abdominal muscles crosses with weakness of the gluteus maximus and medius.
This pattern of imbalance creates joint dysfunction, particularly in the lumbar spine, pelvis, hips, and knees. Specific postural changes seen in LCS include anterior pelvic tilt, increased lumbar curve, and knee straightening. Stress is increased on the low back and hips due to tight muscles and can cause pain in the low back when running, walking, and standing for long periods of time.
LCS is common in females, individuals that sit for most of the day and individuals that perform repetitive activities such as running and jumping. Many common injuries that plaques the active person can stem from LCS. Treatments for lower cross syndrome consist of postural training, Active Release/Graston on overactive muscles, and rehab exercises for underactive muscles.
Additional home treatments for Lower Cross are foam rolling the quad and anterior hip muscles, magnesium supplementation for overactive and sore muscles, and anti-inflammatory nutrition for proper healing.
