Choosing a Self Propelled Wheelchair With Suspension
Self-propelled wheelchairs allow individuals to be independent by allowing them to determine their own the speed, direction and destination. They also help improve the strength of the upper body and cardiovascular health.
Wheelchair suspension helps to cushion sharp shocks, such as drops from thresholds or curbs and also reduce the vibration that is transferred to the MWU. In-wheel suspension systems are a promising alternative to front suspensions for casters.

The height of the seat to the floor of a chair is vital because it determines the ability of the chair to move across different surfaces. The bottom of wheelchairs is a slick surface that allows them to move easily over paved roads, sidewalks, and even indoor surfaces like hardwood floors or tile. When moving outdoors on a rougher terrain, a wheelchair will require grippy treads to allow it to grip better.
A suspension system is installed on the frame of the chair to ensure a smooth ride. A shock assembly is used to absorb and displace energy from the chassis when it encounters uneven or rocky surfaces. The shock assembly comprises a pair of springs that are affixed to the chassis and can be adjusted to change the amount of energy that is transferred from the front to the back or vice versa.
One method to adjust the shock assembly is by using a pin 1201 which can be placed into one of the numerous holes 1102 that are equally spaced. By changing the position of the pin 1201 the amount of movement within the shock assembly can be changed to stiffen or soften the movement of the wheelchair.
In addition to the shock assembly a pair of forward wheels are attached to the chassis. These wheels can also be adjusted and placed in different positions to alter the amount of weight that is transferred from one side on the other. This allows the wheelchair to be adjusted to various types of terrain and also to reduce the strain put on the axles.
The footboard can be adjusted to suit the user's needs. The footboard's height can be adjusted to fit a wide range of users and to allow them to comfortably reach the floor. The length of the footboard may be altered to adjust the pressure on the legs and feet.
Add-ons like mountain bike tires can be attached to wheelchairs to help them navigate through rough terrain. This will not only increase the comfort of the user but will also allow a wide range of places to go that were previously inaccessible.
Seat Size
Getting the correct seat size is crucial to ensure that a self-propelled wheelchair with suspension delivers optimal comfort. A seat that is too small can put undue strain on the muscles and bones. A seat that is too big could result in a sagging posture. It is recommended to consult a wheelchair seating clinic prior to buying to ensure that your seat is set in the best way for your particular impairment.
The frame material you choose will also impact your comfort. Steel frames are strong and offer a high degree of adjustability. However they are heavy and can cause sores for long distances. Aluminium is a substitute that is lighter and offers greater flexibility. Most lightweight aluminium wheelchairs come with a removable footrest to help reduce weight when not being used.
Carbon fibre is the lightest material of all, yet it is also the most expensive. It is only available in premium models. Despite its pricey tag, carbon offers exceptional strength and durability. It is therefore ideal for high-performance wheelchairs and sportsy models.
Aesthetics is an additional aspect to consider in choosing the right wheelchair. Wheelchair manufacturers put a lot of effort into making their products look attractive and a majority of them offer a wide selection of colors as well as contrasting trims and other design elements. Appearance can be subjective and is mostly an individual preference however, a visually appealing chair can boost your confidence.
Empowering Independence
A self-propelled wheelchair with suspension is an excellent way to go out and about for use in the day or at leisure. The right frame and accessories can enhance safety, comfort, and efficiency, whilst customising your wheelchair to fit your lifestyle is a simple way to make it your own.
The Drive Medical Enigma K-Chair, for instance transforms the comfort of wheelchairs with adjustable spring suspension. The rear shock absorbers can be adjusted to smooth surfaces and improve riding comfort. Anti-tip tires with adjustable anti-tip and front suspension increase safety and make kerb climbing easier. The package is completed by an adjustable backrest that is padded to resemble a desk and height-adjustable arms which can be adjusted with just a single click.
Seat to Back Height
It is essential to consider the seat-to-back distance when choosing a self-propelled wheelchair with suspension. A seat that is too high can add extra stress to the legs and thighs, while one that is too low can cause the user to lean forward, which can lead to poor posture and pressure sores. The best chair has a seat height that is between the knees' backs, and the front edge. This will ensure a good sitting position and a uniform distribution of pressure.
Another factor to consider is the distance between the front axle and the front of the wheel. This will impact the amount of force required to push the chair across obstacles. A more narrow axle will require less effort however, it can be difficult to navigate through tight spaces. Wider axles are more comfortable to maneuver, but may not offer enough traction for off-road driving.
In the end, it is crucial to think about the type of wheels to be used. There are a variety of options to pick from, such as pneumatic vs. solid tires. Pneumatic tires have a softer ride but can be more challenging to maintain, while solid tires are more durable and offer an easier ride.
The type of frame you choose is also crucial. Certain frames are made of aluminum that is lightweight and easy to move, whereas others are more robust steel that is able to provide durability. It is also possible to have the frame customised with various accessories, like armrests and footplates. This allows users to tailor their wheelchair to meet their specific needs.
Once the right chair has been selected, it is then an issue of practicing to improve your driving skills. As the user gets more familiar with the chair they will likely require fewer adjustments, allowing them to accelerate further. For those with several years of experience who want the most control and performance, a custom welded wheelchair like TiLite's TR, the RGK Octane Sub4 or Progeo's Joker Energy is an excellent alternative.
Wheelchair add-ons have become increasingly popular. They range from simple track wheels to rear wheels with motors that can be controlled as an electric chair, or assist with each stroke. These can help the user move over kerbs and high thresholds which would otherwise stop them from moving further without assistance, opening up their world and allowing them greater freedom of movement.
Seat to Side Height
Many wheelchair users can benefit from adjustments to the frame as well as the seat cushion and backrests that allow users sit comfortably with good posture. If they don't, their posture will be negatively affected and this can lead to fatigue, pain, decreased self-esteem and even a reduced mobility.
We look at a client's strength and range of motion as well as muscle tone during the seating assessment to determine the best wheelchair for their requirements. It's also important to think about the bone structure, hip position and other medical conditions. This can affect their seating arrangement and the way they use their wheelchair.
The rear and front seat heights are crucial as they determine the height of the seat in relation to the wheels. If a customer sits too high over their wheels, they will not be in a position to reach the rims on their hands. As a guideline it is recommended to reach the wheel hub with your finger or palms when you put your arms by your sides.
For this reason, the standard wheelchair is usually too large for a bariatric client, and some of these clients will eventually use power mobility as their primary wheelchair and use manuals as a backup. However, there are a number of incredible bariatric wheelchairs that are lightweight available today with adjustable frames and seats that can be modified to self-propulsion.
In addition to these light self propelled wheelchairs, there are a variety of travel and transit chairs with smaller frames and wheels to make it easier for storage and transport. They are better suited for transporting passengers in a vehicle, such as minibuses and are usually crash-tested for this purpose.
Most active user wheelchairs are designed for use on pavements. However, they can be equipped with off-road tires and suspension systems to handle rough terrain. Some of these have also been designed to be as versatile and functional as possible with folding armrests that decrease the size of the chair when it is in a parking space and seats that can be flipped backwards, and half-folding footplates to allow easy access.
