Introduction: Understanding Spinal Stenosis
Lumbar spinal stenosis is an anatomical narrowing of the central spinal canal or lateral neuroforamina, most commonly encountered in adults over 60. As the space diminishes, the spinal cord and descending cauda equina nerve roots become mechanically crowded and experience vascular compromise during extension. Its hallmark clinical feature is neurogenic claudication—cramping and heaviness in both legs during walking that is relieved by bending forward or sitting down.

Pathophysiology & Biomechanical Impact
During spinal extension (standing tall, walking), the ligamentum flavum buckles inward and canal diameter narrows by up to 20%. This causes venous congestion, elevated intrathecal pressure, and transient ischemia to the cauda equina roots, manifesting as fatigue and weakness in the legs.
Evidence-Based Physiotherapy Protocols
Home Care & Ergonomic Strategies
- Lean slightly forward when walking or pushing a trolley to maximize canal volume
- Use an inclined walking treadmill or stationary recumbent bike for daily exercise
- Perform double knee-to-chest stretches in bed every morning and evening
- Break prolonged standing intervals by placing one foot on a low step stool
