LATERAL SUBSYSTEM ANATOMY
[balance of the hips] ⚖️
Happy Sunday everyone! Today is a quick post exploring what is called the lateral subsystem of the low back. What this system does is help us to keep our hips level in our day to day activities.
This includes walking, stairs, squatting, etc. We have the glute med/min and TFL on one side( previously discussed) and the quadratus lumborum (QL) on the other. But what about the adductors (groin muscles) 🤨 These are often neglected and will be discussed later on in a future post.
In physio lingo- Our sagittal plane movements ( forwards and backwards) are able to be more efficient because we don’t have as much lateral sway when this system is in tune 👌🏼 (ie - no lost movement in the frontal plane)
With that said, however, how do we look at this system? As the picture above suggests, the single leg stance assessment is a good place to start. This can often be a cause of knee and low back pain. .
Interestingly however, some of the research I have read through from McGill discussed the fatigue resistance side to side and suggested that even if both of the systems are weak, it is the balance that matters- even a 5 percent difference can potentially lead to low back pain. So moving forward this week I’ll be diving a bit more into this system! .
Don’t worry though, I’ll be following up on my previous posts from last week as well. So stay tuned! But also note how this post is taking a step out and looking at the bigger picture 🌎 .
