Lauren Dickerson and Ed Barnett demonstrates how to properly use a cane. Using a cane is appropriate when you have impaired mobility of any kind such as an injury caused by a knee or a hip. First, measure the cane. Hold the cane about four inches away from you and it should come to hip height. When the cane is the right length, your arm should come at a 30 degree angle. Hold the cane on the stronger side of your body. When you walk, bring the cane and your weaker leg out together. Then bring the stronger side back. You want to have two points of support at all time which is why the cane is so effective. You can also get a cane with four prongs for greater stability.
