Flexion-Biased

Lumbar Spinal Stenosis

Spinal stenosis is the narrowing of the central spinal canal or neuroforamina, commonly due to age-related degenerative changes, facet joint hypertrophy, or thickened ligamentum flavum.

CLINICAL PRESENTATION

Common Symptoms

Pain, cramping, or heaviness in both legs when walking or standing (neurogenic claudication)
Immediate relief when bending forward, sitting down, or leaning over a shopping cart
Spinal extension (bending backward) worsens nerve symptoms
Numbness, aching, or weakness in thighs after continuous upright standing

CRITICAL CAUTION

Movements to Avoid

✗ Prone press-ups or standing backward extension (narrows the cross-sectional area of the canal)
✗ Prolonged flat walking without resting in flexion or leaning forward

💡 CLINICAL PHYSICAL THERAPY PEARL

Stenosis responds best to "flexion-biased" programs that increase the cross-sectional area of the spinal canal. Always choose seated or curled postures over backward bending.

STEP-BY-STEP SEQUENCE

Prescribed Exercise Protocol

6 EXERCISES

LUMBAR ELONGATION

🎯 Lower Spine & Lats

Decompression 2-3 mins • 30s

Supported Child’s Pose (Balasana)

Gentle spine elongation that decompresses lumbar vertebrae and releases tight latissimus dorsi.

T8-T9 T9-T10 Erector Spinae Latissimus Dorsi +1

Guide

SPINAL MOBILIZATION

🎯 Facet Joints & Discs

Mobility 2 mins • 5s

Cat-Cow Spinal Waves

Synchronized flexion and extension to lubricate intervertebral discs and restore spine mobility.

C2-C3 C3-C4 Erector Spinae Rectus Abdominis +1

Guide

ANTI-EXTENSION CORE

🎯 Deep Transverse Core

Strengthening 3 mins • 3s

Deadbug Anti-Extension Core Rehab

Re-trains the deep transverse abdominis to protect the lumbar spine during extremity movement.

L1-L2 L2-L3 Transverse Abdominis Internal Obliques +1

Guide

LUMBAR FACET OPENING

🎯 Spinal Canal Foramina

Decompression 2 mins • 30s

Single Knee-to-Chest Lumbar Release

Relieves facet joint irritation and gently stretches the lower back and gluteus maximus in bed or on floor.

L2-L3 L3-L4 Gluteus Maximus Erector Spinae +1

Guide

POSTERIOR PELVIC TILT

🎯 Core Dissociation

Mobility 2 mins • 5s

Supine Pelvic Tilts & Core Awakening

Gentle rocking of the pelvis that frees tight lower lumbar segments and activates the deep transverse core.

L3-L4 L4-L5 Transverse Abdominis Internal Obliques +1

Guide

BILATERAL CANAL WIDENING

🎯 Stenosis Decompression

Decompression 2 mins • 30s

Double Knee-to-Chest Lumbar Hug

Maximum posterior pelvic decompression that widens the spinal canal and relieves lumbar stenosis and facet irritation.

L1-L2 L2-L3 Erector Spinae Gluteus Maximus +1

Guide

CLINICAL QUESTIONS & ANSWERS

Frequently Asked Questions about Spinal Stenosis

Q Why does leaning forward on a shopping cart relieve stenosis pain?

Flexing the lumbar spine anteriorly widens the neuroforaminal canals by up to 24%, relieving mechanical compression on passing spinal nerve roots and alleviating leg claudication.

Q Which exercises are dangerous for lumbar spinal stenosis?

Backward bending (extension), prone press-ups, and prone cobras narrow the spinal canal and should be avoided in favor of flexion-biased decompression routines.
