You are holding the cane in the hand opposite of the leg that is injured or needs help.
This is because this provides the most strength for the weak leg in terms of getting pressure off of it by putting that pressure on the cane and the hand and arm that is holding on to the cane.
Let’s look at an example of this.
The person needs a cane because they injured their left knee after slipping. They spoke to their doctor he recommended using a cane to take the pressure off of the hurt knee so it can heal faster.
What hand do you hold the cane in if the left knee is injured? The right hand. You will hold the cane in the opposite hand of the leg injury.
Now when you start to walk you want to move the cane when you move the injured left leg out as well.
When you start to put pressure down on the injured right leg you will want to then put pressure down on the cane and your right arm and hand.
