Flexion Pain vs Extension Pain — Different Causes
Back Pain Patterns — What movement hurts provides diagnostic clues.
Not all back pain is the same. Some hurt when bending forward, others when extending backward, or after standing for long periods… The pattern determines the cause and treatment direction.
3 Key Points on This Page
- Three main patterns of back pain
- Possible causes for each pattern
- Treatment direction based on patterns
Pattern 1: Pain with Forward Bending (Flexion Sensitivity)
This Applies to You If:
- Hurts when bending forward
- Worsens with prolonged sitting
- Painful when lifting objects from floor
- Stiff after driving
- Difficult to get up in the morning
Possible Causes
- Disc problems — Forward bending increases disc pressure
- Posterior fascia tension — Tight hamstrings, gluteals
- Weak core — Reduced transversus abdominis, multifidus function
Treatment Direction: Reduce disc pressure, release posterior fascia, activate core, learn hip hinge pattern
Pattern 2: Pain with Backward Extension (Extension Sensitivity)
This Applies to You If:
- Hurts when extending backward
- Worsens with prolonged standing
- Painful when reaching high objects
- Improves with rest while walking, hurts again when resuming
- Actually feels better when sitting
Possible Causes
- Facet joint problems — Extension increases joint compression
- Spinal stenosis — Narrowed space where nerves pass
- Anterior fascia tension — Tight iliopsoas, rectus femoris
- Hyperlordosis posture — Excessive backward curve in lower back
Treatment Direction: Reduce facet joint load, release iliopsoas, activate abdominals, learn pelvic neutral position
Pattern 3: Pain with Rotation or Lateral Bending
This Applies to You If:
- Hurts when twisting body
- Pain only on one side
- Worsens with rotational sports (golf, tennis)
- Uncomfortable lying on side
- One leg feels shorter or pelvis feels tilted
Possible Causes
- Quadratus lumborum problem — Lower back side muscle imbalance
- Sacroiliac joint dysfunction — Pelvis-spine connection issue
- Pelvic asymmetry — One side elevated or tilted
- Asymmetric core — Overuse of one-sided muscles
Treatment Direction: Quadratus lumborum trigger point treatment, pelvic alignment, symmetric core strengthening
Combined Patterns Are Common
In reality, combined patterns are more common than single patterns.
- Flexion + Rotation — Bending and twisting simultaneously (lifting while turning)
- Extension + Lateral bending — Extending while tilting to one side
- Load-dependent — Only hurts when lifting heavy objects
- Time-dependent — Hurts when maintaining position (sitting or standing)
That’s why “my back hurts” alone doesn’t identify the cause. Which movement, when, and how it hurts is key to diagnosis.
Our Approach at Yonsei Shinmyung
We accurately identify patterns and reduce problematic movements while strengthening necessary functions.
- Stage 1: Pattern Assessment
Carefully assess which movements hurt and which positions are comfortable. Identify main patterns through flexion/extension/rotation tests. - Stage 2: Downshift (Circulation HD)
Reduce inflammation in sensitive structures (disc, facet joints, fascia) and release trigger points. - Stage 3: Activate & Integrate (Circulation PT)
Activate muscles in deficient patterns and learn movements that protect your back in daily life.
