An abnormally accentuated lumbar curve, whether congenital or acquired, can result in disequilibrium and vulnerability in the lower back.
Sometimes this is partially alleviated with postural counseling, Activator adjustments, and specific exercises. If the patient habitually “locks back” their knees when standing, changing this habit often helps a lot.
Ergonomic counseling about sitting, sleeping, etc. can also help.
But often these are only partial solutions. A patient with this condition may need more consistent chiropractic treatments, the frequency of which can be judged according to what works for each individual.
