Using diagnostic ultrasound we see your core in real time. We can test for normal activity with arm raising and preventing backwards motion. Your core is designed to engage when there is a potential challenge that can strain the back. When we reaise our arms our core is supposed to engage. When we pick up any weight, our core should engage. The truth is that if you have had abdominal surgery, after a baby, or a back injury or chronic aching or pain, your core is probably not doing its job. This test will show us if your core is working. We can also see if you have core engagement when you ask your core to tighten.
