Watch how your patient stands: are their hips shifted forward and their lower back swaying into a deep arch? That exaggerated curve isn’t just a posture label—it’s Lordosis, and it can tell you a lot about muscle balance, mobility, and load through the lumbar spine.
What is Lordosis?
Lordosis (lor-DOH-sis) describes an excessive inward curvature of the lumbar spine, often referred to as swayback or hyperlordosis. While a normal lumbar lordotic curve of roughly 30–50 degrees is healthy and necessary for shock absorption, excessive lordosis increases compressive forces on the posterior spinal structures and alters weight distribution through the facet joints and discs.
Why Lordosis Matters in Physical Therapy Practice
Excessive lordosis often reflects an anterior pelvic tilt, driven by tight hip flexors and lumbar extensors paired with weak abdominals and gluteals. This imbalance can contribute to low back pain, impaired gait efficiency, and decreased tolerance for loaded activities. For your Plan of Care, addressing both mobility and strength is key—stretch what’s tight, strengthen what’s weak, and retrain neutral spine control during functional tasks.
What You’ll See in the Clinic
Your patient may stand with a pronounced sacral angle, abdominal protrusion, and hamstring tightness. They might complain of aching low back pain after standing or walking, especially if they spend long hours sitting. You may also note limited hip extension during terminal stance.
“Patient demonstrates increased lumbar lordosis with anterior pelvic tilt in standing. Thomas test positive bilaterally for rectus femoris and iliopsoas tightness. Abdominal strength 3/5; gluteus maximus 3+/5. Will begin hip flexor stretching, core stabilization, and gluteal activation to reduce lumbar extension during gait.”
Common Pitfall & Pro Tip
⚠️ Pitfall: Don’t assume everyone needs aggressive stretching. Hypermobile patients can also present with lordosis, and forcing end-range flexion may aggravate symptoms. Always assess joint mobility and pain response before prescribing a stretching protocol.
💡 Pro Tip: A simple cue—“Tuck your hips under like a dog tucking its tail”—can help patients feel neutral pelvis position. Pair this with a mirror or photo feedback to build awareness. Don’t forget to assess thoracic mobility, too: a stiff upper back can push the lumbar spine into more extension.
Memory Aid for Lordosis
Think of “the royal arch”: a lord stands tall with an exaggerated, proud arch in their lower back. When you see too much arch, think “over-lorded”—too much curve taking up space where neutral should be.
NPTE Connection
Look for lordosis on exam items related to posture assessment, muscle imbalance patterns, lumbar spine pathology, and interventions like pelvic tilts, hip flexor stretching, and core strengthening.
Related Physical Therapy Concepts
Lordosis frequently overlaps with kyphosis and scoliosis in postural assessments. It’s also closely tied to anterior pelvic tilt, hip flexor tightness, and gluteal inhibition, so your treatment plan should address the entire kinetic chain rather than the lumbar spine in isolation.
Quick Reference
✓ Normal lumbar lordosis: ~30–50° (varies by method) ✓ Priority level: Moderate—consider impact on pain, mobility, and function ✓ PT Interventions/Considerations: • Assess with postural observation, inclinometer, or lateral radiograph • Thomas test for hip flexor length • Stretch hip flexors and lumbar extensors if tight • Strengthen abdominals, glutes, and core stabilizers • Educate on neutral spine positioning during ADLs
Recognizing lordosis early gives you a clear roadmap to restore mobility, improve posture, and reduce stress on the lumbar spine.
