Lumbar Flexion Intolerance
Lumbar - Pathology
Lumbar flexion intolerance is pain provoked by repeated or sustained flexion.
Biomechanical Mechanism
Disc sensitivity and flexion-biased mechanics often increase symptoms during bending or sitting.
Clinical Rationale
Flexion-sensitive backs respond best to load management and neutral spine training.
Practical Solution
Limit flexion provocation and build tolerance through neutral spine mechanics.
Common Compensations
- Avoidance of flexion
- Excess hip hinge
- Protective muscle guarding
Correctives
- Neutral spine training
- Hip hinge mechanics
- Core endurance exercises
- Load management
Progression
- Level 1: Pain-free neutral control
- Level 2: Core endurance
- Level 3: Hip hinge loading
- Level 4: Functional integration
Regression
- Reduce load
- Shorten duration
- Use supported positions
Red Flags
- Progressive neurological deficits
- Bowel/bladder changes
- Severe night pain
Differential Diagnosis
- Disc herniation
- Radiculopathy
- Facet irritation
