Quad Sets! 🦵
The entry point to regaining quad activation following ACL reconstruction. It’s a simple isometric contraction where the goal is to actively tighten the quadriceps without moving the knee. Simple, but not easy.
After ACL injury and surgery, pain, swelling, and changes around the knee can make it harder for the nervous system to fully activate the quad. This is known as muscle inhibition.
A good quad should extend the entire leg and result in a slight lift of the foot. Sometimes switching up the cues works wonders.
So early in rehab, before we can strengthen the quad around the knee, we have to get the quad firing again.
