pain & exercise

Can low back pain worsen with asymmetric core muscle exercise?

Does exercising make a problem worse?

There’s been a lot of research the past few years on the deep core muscles (multifidus, erector spinae, external oblique, and rectus abdominus muscle). A new meta-study found people with low back pain have higher trunk muscle activity globally, and that the activation pattern varies with sub-phases of gait.

Study Conclusion:
“…increased walking velocity challenges the stability of the spine and the control system increases muscular activation and variability level to cope with this problem.”

Dr. Weiniger’s Observation:
If people with LBP do not adapt as well to mere changes in walking velocity, they almost certainly do not adapt as well to more vigorous activity. This may explain why some low back pain patients are unable to exercise without causing a flare-up of their problem.

Possible Solution:  Train to strengthen the weakest link in the chain towards objective functional symmetry.
