Dear Savvy Senior,

Is there anything to know when it comes to buying a cane? My dad has arthritis in his knee and could use a little extra help getting around. What can you tell me?

Raising Cane

Dear Raising:

When it comes to choosing a cane for walking and support, just any old cane won’t do. Canes come in many shapes and sizes today, and choosing the right fit is very important for your dad’s comfort and safety. Here’s what you should know.

Types of Canes

Not surprisingly, the most widely used assistive device in the U.S. is the cane, used by nearly 5 million people. The kind of cane you get for your dad should be determined by the amount of support he needs and the style of the grip he prefers. Here are the basic types of canes you’ll have to choose from:

• Crook or “C” cane. Shaped like a candy cane with the curved handle, this is the most common and basic type of cane and the least expensive, starting as low as $10.

• Ergonomic-handle canes. These types of canes have bigger, ergonomic shaped handles (there are lots of styles to choose from), which provides a more comfortable and secure grip than a crook cane. Usually made of lightweight aluminum or wood, most of the aluminum models are adjustable in height and some even fold up, which is convenient for travel. Prices typically range between $20 and $80.

• Offset-handle cane. This style has a swan neck curve in the upper part of the shaft that puts the user’s weight directly over the cane tip, making it ideal for people who need extra stability. Starting at around $25, offset-handle canes are typically aluminum, adjustable and come with a flat, soft grip handle that’s easy on the hands.

• Knob cane. Also known as brass handle or parrot head cane, this style is best suited for people who need a cane only for balance or mild weight bearing.

• Quad cane. This cane works best for people who need maximum weight bearing and support. As the name implies, quad canes come with four separate tips at the base, usually have an offset flat handle, and cost $30 and up.

Make It Fit

If his cane is too long, it won’t provide the support he needs. Too short, and he’ll have to lean or bend over to use it which is uncomfortable and may even cause him to fall. Many canes are adjustable, but some are not. To make sure your dad’s cane is the right fit, have him stand up with his arms hanging straight down at his side. The top of the cane should line up with the crease in his wrist. With the cane in his hand, his elbow should bend at a comfortable 20-degree angle.

Check the Tip

The rubber tip on the end of your dad’s cane grips the floor and helps provide traction. Make sure the tip is supple and the tread is in good shape. If the tip looks worn, buy a replacement tip at a pharmacy or medical supply store.

How to Use a Cane

A cane should always be held in the hand opposite the leg that needs support. For example, if your dad’s knee pain is on his right side, he should use the cane in his left hand. The cane should then move forward as he steps forward with the bad leg.

When going up stairs, he should lead with the good leg. Going down stairs, the cane and bad leg should go first. To help, the Mayo Clinic offers a slide show on their Web site (www.mayoclinic.com/health/canes/HA0 0064) that shows how to choose and use a cane. It’s also a smart idea to work with your dad’s doctor or physical therapist.

Where to Buy a Cane

You can find canes at drugstores, discount retailers, home medical supply stores and online at sites like www.canemart.com and www.fashionablecanes.com. If money is a concern, with a written prescription from a physician, most insurers, including Medicare, help cover the cost of a new cane.
