Lower Crossed Syndrome

Lower Crossed Syndrome (LCS) is a predictable pattern of alternating tightness and weakness involving core & pelvic musculature as the body attempts to reach homeostasis. As a result, this condition frequently contributes to low back pain. In addition, other conditions of the lower body are associated with LCS: 

• Gluteal tendinopathy
• Iliotibial band syndrome
• Patellofemoral pain syndrome
• Plantar fasciitis.

LCS typically begins when a muscle or muscle group is overused in a particular direction. When this occurs, the muscle becomes shorter and tighter, primarily the iliopsoas or “hip flexor.” The muscles that oppose this action are subject to prolonged stretch and tend to become longer and weaker. 

Those who sit for long periods of time, such as office workers, are at a greater risk of developing LCS. Sitting for long periods causes the hip flexors to become short. Therefore, forcing your gluteal muscles to relax and become weak. 

Muscle balance is required for normal movement. Any muscle imbalances can lead to poor movement patterns- both locally and globally. Consequently, individuals with longstanding postural dysfunction may create joint degeneration.

Traditional diagnoses focus on a “tissue” source for the patient’s symptoms. However, LCS is a “functional” diagnosis. Thus, it requires identifying the underlying factors contributing to structural or tissue problems.

The most common finding of LCS we see in our St. George chiropractic clinic is gluteal muscle weakness. Most of these patients have insufficient hip stability during movement. In addition, gluteal weakness causes hyperactivity in the hamstrings and piriformis. As a result, we often see tenderness or trigger points in these muscles along with weak abdominals. 

Along with muscle tightness, low back pain is often seen with LCS. With normal function, your gluteal muscle works as the primary muscle to extend the hip. When these muscles are weak or lack normal function, your low back and hamstrings must overwork to compensate for gluteal strength loss.
