What’s better for back pain… spine flexion OR extension?

This is an interesting journal article which adds to the discussion regarding the idea that flexion OR extension is better than the other for the treatment of back pain:  MRI evaluation of lumbar spine flexion and extension

As the journal abstract states: "treatment for lumbar spine pain should be based on the symptomatic response to movement and position rather than biomechanical theory."  So in other words, when it comes to the way our backs work, everyone is different and this suggests that using a SINGLE biomechanical model for the treatment of back pain (i.e. spinal flexion OR extension) is based on flawed thinking.  This concept is central to my back treatment programs where we find out what makes YOUR back less painful and then figure out how to stabilize in this pain free (or less painful) position.  Once you are less painful, then you can learn to move safely and without pain… by developing better control of your dynamic spinal stabilizers.  Furthermore, this is my reasoning for suggesting that patients with back pain wear the POSTURE BELT for back pain from ActiveOrtho, as long as it gives back pain relief. If in fact the belt gives pain relief, I would suggest a treatment program that focuses on stabilizing in a neutral spine posture, particularly during sitting.
