Choosing a Self Propelled Wheelchair With Suspension Self-propelled wheelchairs allow independence by allowing users to dictate the pace, direction and location. They also promote upper-body strength and cardiovascular health. Wheelchair suspension can help to cushion shocks that are particularly harsh like drops off thresholds or curbs, and also reduce the vibrations that are that are transmitted to the MWU. In-wheel suspension systems are a viable alternative to front caster suspension. Seat to Floor Height The height of the floor to seat of a wheelchair is crucial as it determines how well the chair moves over different surfaces. Wheelchairs typically have a slick surface on the bottom that allows them to easily move over sidewalks, roads and even indoor surfaces like tile or hardwood floors. However, when they are outdoors on more rough terrain the wheelchair needs to have more aggressive tread, which will allow it to grip the ground more effectively. To ensure a smooth ride for user A suspension system is added to the frame of the chair. A shock assembly is used to absorb and displace energy from the frame whenever it comes across uneven or rough surfaces. The shock assembly consists of a pair of springs that are affixed to the chassis and can be adjusted to change the amount of energy that is transferred from front to back or in reverse. Pin 1201 is used to adjust the shock assemblies by putting it into one of the evenly spaced holes 1102 on the shock assembly. By changing the position the pin 1201, you can make your wheelchair more rigid or soft in its ride by altering the amount of motion within the shock assembly. In addition to the shock assembly two wheels for forward travel are attached to the chassis. These wheels can be adjusted and positioned in a variety of positions to alter the amount of weight that is transferred from one side on the other. This allows the wheelchair to be adjusted to different types of terrain and to help reduce the stress placed on the axles. Another way to adjust the wheelchair is with the footboard. The height of footboards can be adjusted to fit an array of users, and to allow them to comfortably reach the floor. The length of the footboard can be altered to adjust the amount of pressure on the legs and feet. Many wheelchairs can be modified to travel over rough terrain with the addition of accessories such as chunky mountain bike tyres. This will not only improve the comfort of the user, but could also provide many places to visit that were previously not accessible. Seat Size It is crucial to select the correct size of seat for a self-propelled wheelchair with suspension. A seat that is too small puts excessive stress on bones and muscles while a seat that is too large can lead to an uncomfortable posture. Before buying a wheelchair it is recommended to consult a seating clinic. This will ensure that the seat is positioned correctly for your disability. The frame material you choose will also impact your comfort. Steel frames are strong and provide a lot of adjustment. However they can be heavy and can cause sores when traveling long distances. Aluminium is an alternative that is lighter and offers greater flexibility. The majority of aluminium wheelchairs are lightweight and come with a removable footrest to reduce weight when not being used. Carbon fiber is the tiniest material of all, yet it is also the most expensive. It is only available in premium models. Carbon fibre is a premium material that provides strength and durability. This makes it ideal for high-performance wheelchairs as well as sporty models. Aesthetics is another feature to consider when selecting the ideal wheelchair. The manufacturers of wheelchairs put in many efforts to make their products look stunning. They offer a variety of color options, along with contrasting trims and other design elements. Appearance is very personal and is mostly a matter of personal taste but it's worth bearing in the mind that a visually appealing wheelchair can increase your confidence. Empowering Independence A self-propelled, suspension-equipped wheelchair is a great way to get out and about whether for use in the day or at leisure. The right frame and accessories can increase your safety, comfort and efficiency. Making your wheelchair suit your needs is the best way to make it yours. For example the Drive Medical Enigma K-Chair revolutionises the comfort of wheelchairs with its adjustable suspension. The rear shock absorbers can be adjusted in height to help smooth uneven surfaces and enhance riding comfort. Anti-tip tires with adjustable anti-tip and front suspension improve safety and make kerb climbing more comfortable. A padded desk-style backrest and a height-adjustable armrest that can be adjusted with one touch complete the set. Seat to Back Height When selecting a self-propelled wheelchair with suspension, it is crucial to think about the seat to back height. A seat that is too high can cause extra strain on legs and thighs, while one that is too low can cause the user to lean forward which could result in poor posture and pressure sores. The ideal chair has a seat depth between the knees' backs and the front edge. This will guarantee a comfortable sitting posture and even distribution of pressure. The distance between the front wheel and the axle is also crucial. This will affect the amount of force needed to push the chair through obstacles. A narrower axle will require less force, however it may be difficult to navigate in tight spaces. wheelchair self propelled are easier to maneuver, but may not offer enough traction for off-road use. It is also important to consider the type of wheels that will be used. There are many options, such as pneumatic or solid tires. Solid tires are more durable, however solid tires are more difficult to maintain. Pneumatic tires provide an easier ride. The type of frame chosen is also an important aspect. Some frames are made of lightweight aluminium, which is easily maneuverable, whereas others are more robust steel that is able to provide durability. It is also possible to have the frame customised with various accessories, including armrests and footplates. This allows users to tailor their wheelchair to suit their personal needs. Once the perfect chair has been selected, it is then an issue of practicing to improve your driving skills. As the user becomes familiar with the chair, they might require less adjustments and be able to propel further. If you have several years of experience and you want the highest level of performance and control, a custom-welded chair such as TiLite’s TR, RGK's Octane Sub4 or Progeo's Joker Energy are excellent options. Wheelchair accessories are becoming increasingly popular, ranging from basic track wheels to motorized rear wheels which can be controlled in the same way as a powerchair, or that assist each stroke. These can help the user move over thresholds and kerbs which would otherwise stop them from moving further without assistance, opening up their world and allowing the user more freedom of movement. Seat to Side Height Many wheelchair users can benefit from adjustments made to the frame, backrest, and seat cushion. This allows them to sit comfortably and maintain good posture. If they do not, their posture could be impacted negatively and this can cause pain, fatigue, reduced self-esteem and even restricted mobility. We look at a client's strength as well as range of motion and muscle tone during the seating assessment to determine their best wheelchair to meet their requirements. It is also essential to consider their hip position and bone structure as well as any other medical issues. This will influence their seating system and how they drive their chair. The height of the rear and front seats is very important because it determines the position of the seat with respect to the wheels. If a person sits too high above their wheels, they'll not be able to access the hand rims effectively. You should be able touch the wheel hub when you hang your hands at your side. A standard wheelchair might be too high for clients with bariatric issues. Some of these clients make use of power mobility as their primary chair, and the manual wheelchair as a back-up. There are now a number lightweight bariatric chairs on the market, with adjustable frames and seats which can be adapted to self-propel. In addition to these light self propelled wheelchairs, there are a variety of transit and travel chairs that have smaller frames and lighter wheels to make it easier to transport and store. These are best suited for transporting passengers in a vehicle like minibuses and are generally tested for safety in this manner. The majority of active user wheelchairs are designed for use on paved surfaces. However they can be fitted with off-road tyres as well as suspension systems to handle rough terrain. Some of these have also been made to be as adaptable and practical as they can be with foldable armrests that reduce the size of the chair when it is parked, seat cushions that can be turned back and half-folding footplates for easy access.
