Lumbar Flexion Intolerance
Lumbar flexion intolerance is pain provoked by repeated or sustained flexion.
Lumbar - PathologyBiomechanical 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
- 1Level 1: Pain-free neutral control
- 2Level 2: Core endurance
- 3Level 3: Hip hinge loading
- 4Level 4: Functional integration
Regression
- Reduce load
- Shorten duration
- Use supported positions
Red Flags
- Progressive neurological deficits
- Bowel/bladder changes
- Severe night pain
