Why Do Wheelchairs Have Slanted Wheels?

If you’ve ever noticed wheelchairs with slanted or angled wheels, you might wonder why they are designed this way. The slanting of wheels, known as camber, is more than just a design choice; it serves practical purposes that enhance the wheelchair’s functionality, comfort, and safety.

This blog explains why wheelchairs have slanted wheels and how camber benefits wheelchair users.

What Is Wheelchair Camber?

Wheelchair camber refers to the angle at which the wheels tilt outward from the top. A wheelchair with cambered wheels has the tops of the wheels closer together and the bottoms spread further apart. This angle is typically measured in degrees, with common camber angles ranging from 2° to 20°.

Benefits of Slanted Wheels

Slanted wheels offer several advantages for wheelchair users.

Let’s explore these benefits in detail:

1. Improved Stability

Cambered wheels provide a wider base of support, making the wheelchair more stable.

• Reduces the risk of tipping over during sharp turns or on uneven terrain.
• Helps maintain balance when the user leans sideways.

2. Better Manoeuvrability

The angled position of the wheels allows for smoother and easier turning.

• Reduces the effort needed to turn the wheelchair.
• Enhances agility, especially for active users or in sports wheelchairs.
• Ideal for navigating tight spaces or quick directional changes.

3. Comfort and Ergonomics

Slanted wheels help reduce strain on the user’s shoulders and arms.

• Keeps the user’s arms in a more natural position while propelling the wheelchair.
• Minimises the risk of repetitive strain injuries caused by prolonged pushing.

4. Protection for Hands and Fingers

Cambered wheels push the bottom of the wheels further out, keeping them away from the user’s hands.

• Prevents hands and fingers from getting caught between the wheels and obstacles, such as door frames.
• Offers added safety during outdoor use.

Common Uses for Cambered Wheelchairs

Cambered wheels are not found on all wheelchairs but are commonly used in specific scenarios:

1. Sports Wheelchairs

• High camber angles improve manoeuvrability and speed.
• Used in sports like basketball, tennis, and racing.

2. Everyday Use

• Moderate camber angles (around 2° to 6°) improve comfort and stability without making the wheelchair too wide.

3. Off-Road or Outdoor Use

• Cambered wheels provide better balance and stability on uneven surfaces, such as gravel or grass.

Drawbacks of Slanted Wheels

While cambered wheels offer many benefits, they may not be suitable for everyone.

Here are some potential drawbacks:

• Increased Width: The outward tilt of the wheels can make the wheelchair wider, making it difficult to navigate through narrow doorways or tight spaces.
• Higher Cost: Wheelchairs with cambered wheels are often more expensive due to specialised design and components.
• Limited Practicality for Indoors: High camber angles may not be ideal for indoor environments where space is limited.

How to Choose the Right Camber Angle

When deciding on the camber angle for a wheelchair, consider the following factors:

Purpose

• For sports or active use, a higher camber angle (10°–20°) is recommended.
• For everyday use, a lower camber angle (2°–6°) provides a balance between stability and manoeuvrability.

Environment

• Use a higher camber angle for outdoor and uneven terrain.
• Opt for a lower angle for indoor or urban environments with narrow spaces.

Comfort Needs

If you experience strain during wheelchair propulsion, a slight camber can improve ergonomics and reduce discomfort.

Summary

Slanted wheels on wheelchairs, or camber, are designed to enhance stability, manoeuvrability, and user comfort. While particularly beneficial for sports and active users, cambered wheels can also improve the daily experience for many wheelchair users. However, it’s important to choose the right camber angle based on your needs and environment.

If you’re considering a wheelchair with slanted wheels, consult with a mobility specialist to ensure you find the perfect fit. By understanding the advantages and limitations of camber, you can make an informed decision and enjoy a more comfortable and efficient wheelchair experience.
