My current intern and I recently had a young, 16 y/o female patient with a 3 year case of low back pain (yes, 3 yrs and just came to see us). To make a long story short, after getting her symptoms calmed down (she had allodynia setting in to her low back), we started to perform more higher level activities as she is an all-state sprinter. To find out, she could not hold herself up in a plank position to save her life!
We both were at awe of how “weak” her core was…especially considering she is an avid sprinter and recently competed in indoor track state finals. So, I brought up this picture for my intern on McGill’s work on endurance norms for low back.
I am not a big advocate personally of simply looking at these norms to determine her level of performance, but I would like to see what others out there think.
