People use canes primarily to reduce pain, improve balance, and move safely when a leg, joint, or neurological condition makes walking difficult on its own. About 16% of older adults in the United States use a cane, making it the most common mobility device by a wide margin. The reasons range from chronic arthritis to recovery after a stroke to simply feeling steadier on uneven ground.
Pain Relief and Joint Protection
The most common reason people reach for a cane is pain. Osteoarthritis of the knee or hip, lower back injuries, and conditions that cause leg weakness all make walking uncomfortable or exhausting. A cane held on the opposite side of the painful joint shifts some of your body weight away from it with every step. Without any training, most people offload about 7% of their body weight through a cane. With just 10 minutes of instruction on proper technique, that number jumps to around 9 to 10%, which is enough to meaningfully reduce the load on a damaged knee or hip joint.
That might sound modest, but consider that your knee absorbs several times your body weight with each step. Shaving even a small percentage off that force, thousands of times a day, adds up. For people with knee osteoarthritis, reaching a 10% offload target has been shown to significantly reduce the twisting force that wears down cartilage on the inner side of the knee.
Balance and Fall Prevention
Balance problems are the second major reason people use canes, and the mechanism here is more interesting than most people realize. A cane doesn’t just give you a third point of contact with the ground. It sends a stream of sensory information to your brain.
Your body maintains balance using three inputs: vision, the inner ear, and proprioception (the sense of where your body is in space, drawn largely from pressure sensors in your feet and joints). When any of these systems weakens, whether from aging, nerve damage, or conditions like diabetes that reduce sensation in the feet, balance suffers. A cane compensates by creating a new channel of sensory input through the hand. Research published in Frontiers in Neuroscience found that when a cane touches the ground, the brain processes it much the same way it would process your fingertip touching a solid surface. Your hand and arm muscles relay information about your body’s position relative to the ground, giving the brain data it can use to fine-tune your posture in real time.
This sensory effect is so powerful that it reduces body sway even when the cane bears almost no weight at all. For people with reduced foot sensation or poor vision, the cane essentially substitutes for missing information. In sighted people, the stabilizing effect of a cane overlaps heavily with vision, meaning both systems feed the brain similar spatial data. But in low-light conditions or unfamiliar environments, that extra haptic input becomes critical.
Specific Conditions That Lead to Cane Use
A wide range of diagnoses can make a cane useful. The most common include:
- Osteoarthritis of the knee, hip, or ankle, where the goal is reducing joint load and pain
- Stroke recovery, where one side of the body is weakened and a quad cane (with four tips for a wider base) can improve stability
- Peripheral neuropathy, often from diabetes, which reduces sensation in the feet and impairs balance
- Lower back conditions like spinal stenosis, where walking upright becomes painful and a cane helps redistribute forces
- Post-surgical recovery from hip or knee replacement, typically as a transitional aid
- Multiple sclerosis, Parkinson’s disease, and other neurological conditions that affect coordination, strength, or both
For elderly adults more broadly, a cane can be the difference between staying independent and needing full-time assistance. The average age of mobility device users in the U.S. is about 80, and roughly 58% are women.
The Confidence Factor
Fear of falling is one of the most underappreciated reasons people start using a cane, and the relationship is complicated. Data from the National Health and Aging Trends Study found that worry about falling severe enough to limit daily activity was 30% higher among cane users compared to people who didn’t use any device. That doesn’t mean the cane causes the worry. It likely reflects the fact that people who already feel unsteady are the ones who pick up a cane in the first place.
The concern, though, is that some cane users respond to their fear by doing less rather than more. They limit outings, avoid stairs, and reduce physical activity, all of which accelerate the muscle loss and deconditioning that made them unsteady to begin with. A cane should enable more activity, not less. If you find yourself using one primarily to feel safe while avoiding movement, that’s a signal to look into balance training or physical therapy alongside the cane.
Choosing the Right Type
Not all canes serve the same purpose. A standard single-point cane works well for mild balance issues, minor leg weakness, or moderate joint pain. It’s lightweight and easy to maneuver but provides the least structural support.
A quad cane, with four small feet at the base, offers a much broader base of support and can stand upright on its own. Quad canes are commonly recommended for people recovering from a stroke who need more stability than a single point provides but aren’t ready for a walker. The trade-off is that quad canes are heavier, slower to use on stairs, and can feel awkward on uneven terrain.
Proper fit matters more than most people think. A cane that’s too tall forces your shoulder up and throws off your gait. One that’s too short makes you lean forward, straining your back. The general guideline is that when you’re standing upright in your normal shoes, the top of the cane should align with the crease of your wrist, allowing a slight bend at the elbow (about 15 to 20 degrees) when you grip it.
Risks of Overreliance
A cane used correctly is a valuable tool, but leaning on one too heavily can create new problems. Research in the Journal of Physical Therapy Science found that increased dependence on a cane during walking places significant strain on the shoulder and elbow joints of the arm holding it. Over time, this can lead to shoulder arthritis, elbow injuries, and even nerve compression in the wrist and forearm from the repetitive loading.
The pattern is straightforward: the more weight you channel through the cane, the more your upper body has to absorb forces it wasn’t designed to handle on a sustained basis. This is most concerning for people who use a cane for years and gradually shift more and more load onto it as their lower body weakens. The goal with a cane should be supplementing your leg strength and balance, not replacing them.
Canes for Visual Impairment
White canes serve an entirely different purpose. Rather than bearing weight, they scan the environment ahead for obstacles, curbs, and changes in terrain. The latest generation of smart canes builds on this concept with technology. The WeWALK Smart Cane 2, released in late 2025, integrates ultrasonic sensors that detect obstacles up to 9.5 meters away, including overhead hazards like signs and low-hanging branches that a traditional white cane would miss entirely. It also includes AI-powered voice navigation for turn-by-turn directions and a voice assistant that can describe nearby landmarks.
These devices represent a fundamentally different use case from orthopedic canes. The user typically has full leg strength and balance. The cane is their primary tool for spatial awareness, replacing the visual information that sighted people take for granted.
