Lower Crossed Syndrome
Lumbar/Pelvis - Postural
Lower crossed syndrome is characterized by tight hip flexors and lumbar extensors with weak abdominals and glutes, often resulting in anterior pelvic tilt.
Biomechanical Mechanism
Muscle imbalance creates an anterior pelvic tilt and increased lumbar lordosis, reducing hip extension efficiency.
Clinical Rationale
Lower crossed syndrome increases lumbar stress and impairs hip mechanics. Corrective work improves alignment and function.
Practical Solution
Address tight hip flexors and reinforce glute/core activation to restore pelvic alignment.
Common Compensations
- Lumbar hyperlordosis
- Gluteal inhibition
- Rib flare
Progression
- Level 1: Mobility
- Level 2: Activation
- Level 3: Integrated patterns
- Level 4: Loaded movement
Regression
- Reduce load
- Use supported positions
- Limit ROM
Red Flags
- Severe pain
- Neurological symptoms
Differential Diagnosis
- Hip flexor contracture
- Lumbar facet irritation

Evidence
Level: mixed
Posture and lumbopelvic alignment changes with exercise are inconsistent across studies.
