Single leg stance, bouncing a ball on the floor (Balance, single-leg, bouncing ball against floor)

Stand on your affected leg, holding a ball.
Ensure you do not rest your elevated leg on the stance leg.
Get your balance before you bounce a medium sized ball on the floor, hard enough so it should bounce back to you.
If this is difficult to do with both arms, then use your strongest arm.
Try to keep your head as upright as possible.
