Let’s take a look at core strength and stability for the pelvic girdle and low back.
First of all – what is meant by your Core Musculature? Well, this largely depends on who you ask. As physical therapists, we mean the deep muscles that stabilise your body, and allow other, larger muscles to create movement from a firm base – the foundations if you like. The 2 most important areas for this core stability are for the shoulder girdle and neck; and for the pelvic girdle and lower back (the subject of this post).
As humans, we stand upright, using our spine as a pillar, which needs to be supported to stay that way; that support largely comes from the deep intrinsic lumbar muscle group (especially multifidus) which tether each vertebra onto the one below, alongside the transverse abdominus muscle which acts more like a weight-lifter’s belt… that’s active, in the right place, and with you 100% of the time; these are “backed up” by the diaphragm and pelvic floor musculature.
Unfortunately, the deep intrinsic muscles are directly inhibited by pain in the lumbar or pelvic areas, and waste away quite quickly; it is also a muscle group for which you have limited to no conscious control. Despite lacking control over these muscles, they will contract alongside the transverse abdominus muscle; which is how you can go about strengthening and stabilising your spine. Once you have that stability your lumbopelvis will move more efficiently, with less chance of injury, and if/when injured, may recover more quickly.
