What does knee stability actually mean?
For many people, it starts with the quadriceps muscles.
After a knee injury, surgery, or even significant swelling, the quadriceps can become less effective at supporting the knee. Before a muscle gets stronger, it often has to relearn how to fire properly.
That's why Brooke's first exercise is a simple quad set. The progression then moves from muscle activation to greater stability and strength through increasingly challenging positions.
Watch Brooke, DPT, OCS, demonstrate three exercises that can help you build a stronger foundation for knee stability, from non-weight-bearing activation to a wall sit.
Give these exercises a shot and see if they help you identify any side-to-side differences in knee stability or control.
