Single-leg balance

1. Stand on a flat surface with your arms stretched out to your sides like you are making the letter "T." Then lift your good leg off the floor, bending it at the knee. If you are not steady, use one hand to hold on to a chair, counter, or wall.
2. Standing on your affected leg, keep that knee straight. Try to balance on that leg for up to 30 seconds, and then rest.
3. Repeat 8 to 12 times.
4. It's a good idea to repeat these steps with your other leg.

When you can balance on your affected leg for 30 seconds with your eyes open, try to balance on it with your eyes closed.

When you can do this exercise with your eyes closed for 30 seconds with ease and no pain, try standing on a pillow or piece of foam.
