Position a one-step stool in front of you. Have a stable object like the back of a chair near you so you can hold it to steady yourself.
Slowly step up on to the stool with your affected leg. While stepping up with your affected leg, avoid putting pressure on your good leg, and use your affected leg to step up.
Then bring your good leg up to the stool.
Keeping your gaze straight, step up with your affected leg and then your good leg back to the stool.
Repeat the above steps at least 8 to 10 times.
