Components of Manual Wheelchairs
Manual wheelchairs have different parts that improve comfort, function, and ease of use. Below are the main components:
Rear Wheels and Front Casters
- Rear Wheels: These are large and include tires, push rims, and spokes (or mag wheels). They allow the user to move easily and self-propel using the push rims.
- Front Casters: These smaller wheels are at the front of the chair. They provide stability and maneuverability. Some models for sports or rough terrain may have one small front wheel instead of two.
Wheel Components
- Wheel Parts: Each wheel has a rim, push rim, spokes, hub, and tire. These parts work together to make the wheelchair move smoothly and allow for easy self-propulsion.
Wheel Locks (Brakes)
- Wheel Locks: These locks act as parking brakes to keep the wheelchair in place during transfers or when stationary. They can be push-to-lock or pull-to-lock and may be retractable, with some models featuring locks that swing away when not in use.
Handles
- Push Handles: These are for caregivers to help push the wheelchair when needed. They are placed at a comfortable height and angle for the caregiver.
Footrests
- Footrests: These support the user’s legs and feet. They can be fixed, folding, or swing-away, depending on the user’s preference. Adjustable footrests allow for better comfort and positioning.
Armrests
- Armrests: These provide support when the user is sitting still. They come in different styles, such as wraparound, full-length, or desk-length, and can be fixed, height-adjustable, removable, or flip-back. Properly fitted armrests also help with efficient wheelchair propulsion.
Seat and Backrest
- Seat: The seat’s width, height, and angle are important for comfort and stability. Adjusting the seat helps prevent pressure sores and allows easy access to the push rim for self-propulsion.
- Backrest: Adjustable backrests offer support for posture and can be modified for height and angle to improve stability and help with daily tasks.
Frame and Materials
- Frame Type: The frame can be folding or rigid. Rigid frames are more maneuverable, while folding frames are easier to transport. Frames are made from materials like aluminum, chromoly, stainless steel, titanium, or composite materials. Lighter materials, like titanium, are more expensive but provide better portability.
Camber
- Camber: This refers to the angle of the rear wheels. A slight camber makes the chair more stable and easier to maneuver. However, too much camber can make it harder to fit through doorways.
Frame Taper
- Frame Taper: Some wheelchairs have a tapered frame, which makes it easier for the user to access the front of the chair, such as during toilet transfers. But this may affect the ability to fold the chair or use certain cushions.
Leg Rests and Footplates
- Leg Rests: These can be standard, elevating (ELR), or swing-away designs and help with comfort and proper leg positioning.
- Footplates: Footplates can be rigid, adjustable, or flip-back. They help with proper foot placement and provide comfort during use.
These components work together to make manual wheelchairs adaptable to different needs, ensuring comfort, safety, and ease of use.
Categories of Manual Wheelchairs

These categories reflect the variety of manual wheelchairs available, ensuring users can find one that suits their lifestyle, medical needs, and personal preferences.
Propulsion Of Manual Wheelchair
Propelling a manual wheelchair involves two main phases: the push phase and the recovery phase.
- Push Phase: This starts when the hands touch the push rims and continues as the user pushes forward to generate momentum.
- Recovery Phase: This begins when the hands release the push rims and swing back to the starting position for the next push.
Pushing Technique
To move the wheelchair forward, the user uses a push-pull motion. One hand pushes down on one push rim while the opposite hand pulls up on the other, creating a continuous cycle of propulsion. This motion helps maintain momentum and control direction.
Stroke Patterns
There are different stroke patterns depending on the environment and propulsion needs: – Semicircular: In this technique, hands drop below the hand rims during recovery. This promotes better biomechanics and energy conservation, especially on flat ground. – Arc Propulsion: The hands follow an arc-shaped path, which works well for uphill propulsion where short, frequent strokes are needed for control. – Single Loop-Over Propulsion: Here, hands rise above the push rims during recovery, though it can be less efficient and require more effort. – Double Loop-Over Propulsion: This is a variation of the semicircular technique, involving two loops during recovery, which helps reduce shoulder strain.
Body Position and Grip
Proper body position is crucial for efficient propulsion. Sit with your back against the backrest and feet flat on the footrests to maintain balance. A firm grip on the push rims is essential. Coordinate arm and hand movements to ensure smooth, efficient strokes.
Axle Position
The position of the wheelchair’s axle affects propulsion efficiency: – Forward Axle: A forward axle position allows for longer, smoother strokes, reducing the number of pushes and improving efficiency. – Rearward Axle: A rearward axle position may shorten the stroke length, requiring more pushes.
Uphill and Downhill Propulsion
- Uphill: Lean forward slightly to shift your weight over the front wheels, and push both rims simultaneously for steady movement.
- Downhill: Apply gentle braking by pressing the push rims while leaning slightly back to maintain stability and prevent tipping.
Consistent Rhythm
Maintaining a steady rhythm is key for effective propulsion. Avoid sudden or jerky movements for a smooth, stable ride.
Practice and Control
Start in a safe, controlled environment to build confidence. Gradually increase the complexity of maneuvers. Consistent practice improves control and efficiency over time.
Goals of Use Manual Wheelchair
The goals of using a manual wheelchair focus on providing users with safe, comfortable, and independent mobility while addressing their specific needs.
Providing Safe and Efficient Mobility
The main goal of a manual wheelchair is to offer users safe and effective mobility. Whether indoors, outdoors, or in the community, the wheelchair should enable easy movement without sacrificing safety or comfort.
Independent or Dependent Mobility
Manual wheelchairs support both independent and dependent mobility based on the user’s abilities. Some users may move the wheelchair on their own, while others may need assistance. The wheelchair should meet these needs, whether used full-time or part-time.
Meeting Mobility Requirements for Daily Activities
A key goal is to help users complete Mobility-Related Activities of Daily Living (MRADLs). The wheelchair should enable users to perform these tasks safely and efficiently without slowing them down or making them unsafe.
Environmental Adaptability
The wheelchair must adapt to different environments, from smooth floors to carpets and outdoor terrains. This may include adding features like suspension to improve comfort and ease of movement over obstacles.
Achieving Personal and Professional Goals
