Standing and walking puts less strain on the spine than sitting so try to stand and walk as much as possible rather than sitting too much. In the first few weeks, it is better to take breaks by lying down rather than sitting.
The use of a walker may be helpful for the first few days. Be sure to try to walk as tall as possible. Try to get up every hour for a short walk.
Progressing to upright standing
Try gradually to achieve as upright a spine as possible. “Think tall” and your muscles will know what to do. Imagine that you are walking with a book on your head. Keep your head up and this will help to keep the spine more correctly aligned, again as close to neutral as it can comfortably get.
