Lumbar Flexion Syndrome

Lumbar Flexion Syndrome

Medical Diagnoses:

  • Acutely herniated disk
  • Lumbosacral strain
  • lumbago
  • degenerative disk disease


Your pain is worse in sitting or when you bend forward.  Your pain may be localized to your back, or it may travel down 1 leg (probably not both legs).  This is a result of excessive motion into flexion (bending), possibly as a result of decreased motion elsewhere in the body (hips, thoracic spine).


Men are more likely than women

Younger people are more likely than older people

Diagnostic Tests:

  • Forward Bend: increased lumbar flexion and possibly pain
    • Secondary Test: decreased pain with hip hinge
  • Supine bilateral and unilateral hip and knee flexion: increased lumbar flexion and possibly pain
    • Secondary Test: reduced pain when stopping motion when lumbar flexion begins
  • Prone position reduces pain
  • Sitting posture reveals decreased lumbar lordosis and possibly pain
    • Secondary Test: reduced pain with upright posture
  • Quadruped Rocking: painful and increased lumbar flexion
    • Secondary Test: reduced pain with neutral spine
  • Seated Knee Extension causes posterior pelvic tilt and possibly pain
    • Secondary Test: reduction in pain, posterior pelvic tilt with decreased ROM

Comerford Tests:

  • Standing: Trunk Lean
  • 4 Point: Backward Push
  • Crook Lying: Double Bent Leg Lift
  • Sitting: Forward Lean
  • Sitting: Chest Drop
  • Sitting: Double Knee Extension
  • Stand to Sit: Ischial Weight Bearing

SFMA: Multi-Segmental Flexion + Breakouts


  • Decrease / eliminate spinal flexion in daily activities, especially sitting.
  • Improve mobility of hips and hamstrings to allow more motion in the lower extremities versus the spine.
    • single knee to chest for hip stretch
    • rectus abdominis stretch – supine shoulder flexion
    • unilateral prone shoulder flexion or unilateral prone hip extension
    • quadruped rocking in extension
    • seated knee extension
    • waiter’s bow / hip hinge > deadlift and squat
    • standing shoulder flexion
    • single leg deadlift
    • lunge
    • birddog

    Dr.Robert Stalker in Halifax told me he would get in trouble if I a poor person used this like to learn about the health issues I and many other people go through to learn to heal and help would get him into trouble and that this is only for rich people…. Can you send me a email explaining why this dubble standard is in place or that he thinks he’s better than me because I did not pay to
    go to school to be a doctor.
    Sincerely Greg at
    I’m pretty sure that he’s just an ass for stating that..
    Thank you for your I have lumbar and cervical rotation syndrome and I believe I can help people and doctors with what I have learned through adversity and this page if anyone would like to learn from me and my time is free..

    1. I’m not sure why so people are so confident and willing to dismiss other sources. In the future, we will have computers giving us constant reminders of other options and we will have to be open minded as medical professionals. The only way to succeed is to admit your own limitations and constantly try to learn more.
