You may have noticed tennis balls attached to the legs of walkers in hospitals, care facilities, or homes. A standard walker is typically composed of a lightweight metal frame, handgrips, and small, firm rubber tips on the bottom of its legs. This modification addresses functional limitations of the standard tips, which can hinder movement for the user. This article explores the reasons behind this popular adaptation and reviews the commercially designed alternatives now available.
Reducing Friction and Noise
The standard rubber tips on walker legs are designed for traction and stability on smooth, dry surfaces. These small-diameter tips present a significant challenge when a walker user attempts to move across carpeted floors or uneven surfaces. The rubber material and small contact point increase friction, causing the walker to snag on carpet fibers or catch on small bumps, forcing the user to expend effort to lift the device with every step.
The larger surface area and synthetic felt covering of a tennis ball enable the walker to glide smoothly across the floor. This mechanism distributes the user’s downward force over a wider area, reducing the pressure on the floor surface. The reduced friction allows the user to push the walker forward with less effort, which is helpful for individuals with limited upper-body strength. The soft, pliant material also dampens noise when the walker is moved across hard surfaces such as tile, wood, or linoleum.
Proper Installation and Safety
The modification involves cutting an “X” or a small slit into the tennis ball and fitting it over the bottom of the walker leg. The cut must be precise enough to hold the ball securely in place to prevent it from slipping off during use. While this do-it-yourself solution is inexpensive and widely adopted, tennis balls are not officially rated as medical devices.
The material of a tennis ball is not engineered for consistent, long-term support and presents safety drawbacks. Over time, the balls may wear unevenly, leading to a tilted or unstable walker that can affect the user’s balance. The felt also collects dirt and debris, and the material can eventually split or tear, creating a tripping hazard. Therefore, the balls require frequent inspection and replacement to maintain a stable walking platform.
Commercial Glides and Alternatives
In response to the popularity and limitations of the tennis ball modification, manufacturers have developed commercial alternatives. These products, often called walker glides, skis, or glide balls, are constructed from durable plastic, specialized rubber, or felt-covered polymers. Unlike the homemade solution, these commercial glides are designed specifically to fit standard walker tubing, ensuring a consistent and secure attachment.
Walker skis are elongated, low-profile plastic pieces that allow the walker to slide over thresholds and uneven surfaces with greater ease than a ball. These alternatives offer durability and consistent glide quality without the risks of uneven wear or splitting inherent to a standard tennis ball. Many commercial glides also feature a reinforced opening and a more durable material composition, providing a longer-lasting, predictable, and safer movement solution for walker users.
