Lumbopelvic retraining

It has to be targeted and with a specific goal: building up the glutes, the abdominals and the lumbar muscles. It is not about moving more in general, it is about working the groups that stabilise the pelvis and the lower back.

It does not widen the canal, it acts on what happens inside it. Strengthening those muscles stabilises the abnormal movement of the segment and indirectly tightens the ligaments of the canal, and in mild or moderate stenosis that may be enough to control the symptoms.

Generally no, and if the problem stems from instability it may be the opposite of what you need. That segment already moves more than it should: stretching routines and flexibility work give it still more range. What we are after here is stability, not mobility; the work is about holding, not loosening. It is the most common misunderstanding, and the one that makes a well-meant programme make things worse.

For as long as you want the benefit. The muscles that stabilise the pelvis and the lower back are built over months, not weeks, and they stop holding as soon as the work is dropped. This is not a treatment with a discharge at the end, it is a change that is kept up.

Then we move to the next step, which is graded according to the region affected, the severity and whether there is back pain or instability. Having started here is not wasted time: it is what shows which part of the problem cannot be solved without touching the spine.
