A wheelchair, often abbreviated to just 'chair', is a chair with wheels, used when walking is difficult or impossible due to illness, injury, or disability. Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as seen with sports wheelchairs and beach wheelchairs. The most widely recognised distinction is between powered wheelchairs ('powerchairs'), where propulsion is provided by batteries and electric motors, and manually propelled wheelchairs, where the propulsive force is provided either by the wheelchair user/occupant pushing the wheelchair by hand ('self-propelled'), or by an attendant pushing from the rear ('attendant propelled').

Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as seen with sports wheelchairs and beach wheelchairs. The most widely recognised distinction is between powered wheelchairs ('powerchairs'), where propulsion is provided by batteries and electric motors, and manually propelled wheelchairs, where the propulsive force is provided either by the wheelchair user/occupant pushing the wheelchair by hand ('self-propelled'), or by an attendant pushing from the rear ('attendant propelled'). Contents.HistoryThe earliest records of wheeled furniture are an inscription found on a stone slate in China and a child’s bed depicted in a on a Greek vase, both dating between the 6th and 5th century BCE. The first records of wheeled seats being used for transporting disabled people date to three centuries later in China; the Chinese used early wheelbarrows to move people as well as heavy objects.

A distinction between the two functions was not made for another several hundred years, around 525 CE, when images of wheeled chairs made specifically to carry people begin to occur in Chinese art.Although the Europeans eventually developed a similar design, this method of transportation did not exist until 1595 when an unknown inventor from Spain built one for. Although it was an elaborate chair having both armrests and leg rests, the design still had shortcomings since it did not feature an efficient propulsion mechanism and thus, requires assistance to propel it. This makes the design more of a modern-day highchair or portable throne for the wealthy rather than a modern-day wheelchair for the disabled.In 1655, a 22 year old watchmaker, built the world's first self-propelling chair on a three-wheel chassis using a system of. However, the device had an appearance of a hand bike more than a wheelchair since the design included hand cranks mounted at the front wheel.The invalid carriage or brought the technology into more common use from around 1760.In 1887, wheelchairs ('rolling chairs') were introduced to so invalid tourists could rent them to enjoy the Boardwalk. Soon, many healthy tourists also rented the decorated 'rolling chairs' and servants to push them as a show of decadence and treatment they could never experience at home.In 1933 Harry C.

Jennings, Sr. And his disabled friend Herbert Everest, both, invented the first lightweight, steel, folding, portable wheelchair. Everest had previously broken his back in a mining accident. Saw the business potential of the invention and went on to become the first mass-market manufacturers of wheelchairs.

Their 'X-brace' design is still in common use, albeit with updated materials and other improvements. The X-brace idea came to Harry from the men’s folding “camp chairs / stools”, rotated 90 degrees, that Harry and Herbert used in the outdoors and at the mines. 19th century wheelchairTypes of wheelchairThere are a wide variety of types of wheelchair, differing by propulsion method, mechanisms of control, and technology used. Some wheelchairs are designed for general everyday use, others for single activities, or to address specific access needs. Innovation within the wheelchair industry is relatively common, but many innovations ultimately fall by the wayside, either from over-specialization, or from failing to come to market at an accessible price-point.

The is perhaps the best known example of this in recent years.Manual self-propelled wheelchairsA self-propelled manual wheelchair incorporates a frame, seat, one or two footplates (footrests) and four wheels: usually two caster wheels at the front and two large wheels at the back. There will generally also be a separate seat cushion. The larger rear wheels usually have push-rims of slightly smaller diameter projecting just beyond the tyre; these allow the user to manouevre the chair by pushing on them without requiring them to grasp the tyres. Manual wheelchairs generally have brakes that bear on the tyres of the rear wheels, however these are solely a parking brake and in-motion braking is provided by the user's palms bearing directly on the push-rims. As this causes friction and heat build-up, particularly on long downslopes, many wheelchair users will choose to wear padded wheelchair gloves. Manual wheelchairs often have two push handles at the upper rear of the frame to allow for manual propulsion by a second person, however many active wheelchair users will remove these to prevent unwanted pushing from people who believe they are being helpful.Everyday manual wheelchairs come in two major varieties, folding or rigid.

Folding chairs are generally low-end designs, whose predominant advantage is being able to fold, generally by bringing the two sides together. However this is largely an advantage for part-time users who may need to store the wheelchair more often than use it. Rigid wheelchairs, which are increasingly preferred by full-time and active users, have permanently welded joints and many fewer moving parts. This reduces the energy required to push the chair by eliminating many points where the chair would flex and absorb energy as it moves. Welded rather than folding joints also reduce the overall weight of the chair. Rigid chairs typically feature instant-release rear wheels and backrests that fold down flat, allowing the user to dismantle the chair quickly for storage in a car.

A few wheelchairs attempt to combine the features of both designs by providing a fold-to-rigid mechanism in which the joints are mechanically locked when the wheelchair is in use.Many rigid models are now made with ultralight materials such as aircraft-grade and, and wheelchairs of composite materials such as carbon-fibre have started to appear. Ultra lightweight rigid wheelchairs are commonly known as 'active user chairs' as they are ideally suited to independent use.

Another innovation in rigid chair design is the installation of shock absorbers, such as Frog Legs, which cushion the bumps over which the chair rolls. These shock absorbers may be added to the front wheels, to the rear wheels, or both.

Rigid chairs also have the option for their rear wheels to have a camber, or tilt, which angles the tops of the wheels in toward the chair. This allows for more mechanically efficient propulsion by the user and also makes it easier to hold a straight line while moving across a slope. Sport wheelchairs often have large camber angles to improve stability.Rigid-framed chairs are generally made to measure, to suit both the specific size of the user and their needs and preferences around areas such as the 'tippyness' of the chair - its stability around the rear axle. Experienced users with sufficient upper-body strength can generally balance the chair on its rear wheels, a 'wheelie', and the 'tippyness' of the chair controls the ease with which this can be initiated. The wheelie allows an independent wheelchair user to climb and descend curbs and move more easily over small obstacles and irregular ground such as cobbles.The rear wheels of self-propelled wheelchairs typically range from 20–24 inches (51–61 cm)in diameter, and commonly resemble bicycle wheels. Wheels are rubber-tired and may be solid, pneumatic or gel-filled. The wheels of folding chairs may be permanently attached, but those for rigid chairs are commonly fitted with quick-release axles activated by depressing a button at the centre of the wheel.All major varieties of wheelchair can be highly customized for the user's needs.

Such customization may encompass the seat dimensions, height, seat angle, footplates, leg rests, front outriggers, adjustable backrests and controls. Various optional accessories are available, such as anti-tip bars or wheels, safety belts, adjustable backrests, tilt and/or recline features, extra support for limbs or head and neck, holders for, walkers or oxygen tanks, drink holders, and mud and wheel-guards as clothing protectors.Light weight and high cost are related in the manual wheelchair market. At the low-cost end, heavy, folding steel chairs with sling seats and little adaptability dominate. Users may be temporarily disabled, or using such a chair as a loaner, or simply unable to afford better. These chairs are common as 'loaners' at large facilities such as airports, amusement parks and shopping centers.

A slightly higher price band sees the same folding design produced in aluminium. Price typically then jumps from low to mid hundreds of pounds/dollars/euros to a four figure price range, with individually custom manufactured lightweight chairs with more options. The high end of the market contains ultra-light models, extensive seating options and accessories, all-terrain features, and so forth. The most expensive manual chairs may rival the cost of a small car.Manual attendant-propelled wheelchairsAn attendant-propelled wheelchair is generally similar to a self-propelled manual wheelchair, but with small diameter wheels at both front and rear. The chair is maneuvered and controlled by a person standing at the rear and pushing on handles incorporated into the frame. Braking is supplied directly by the attendant who will usually also be provided with a foot- or hand-operated parking brake.These chairs are common in institutional settings and as loaner-chairs in large public venues.

They are usually constructed from steel as light weight is less of a concern when the user is not required to self-propel.Specially designed transfer chairs are now required features at airports in much of the developed world in order to allow access down narrow airliner aisles and facilitate the transfer of wheelchair-using passengers to and from their seats on the aircraft.Powered wheelchairs. Main article:An electric-powered wheelchair, commonly called a 'powerchair' is a wheelchair which additionally incorporates batteries and into the frame and that is controlled by either the user or an attendant, most commonly via a small joystick mounted on the armrest, or on the upper rear of the frame.

For users who cannot manage a manual joystick, headswitches, chin-operated joysticks, controllers or other specialist controls may allow independent operation of the wheelchair. Ranges of over 10 miles/15 km are commonly available from standard batteries.Powerchairs are commonly divided by their access capabilities. An indoor-chair may only reliably be able to cross completely flat surfaces, limiting them to household use. An indoor-outdoor chair is less limited, but may have restricted range or ability to deal with slopes or uneven surfaces. An outdoor chair is more capable, but will still have a very restricted ability to deal with rough terrain.

A very few specialist designs offer a true cross-country capability.Powerchairs have access to the full range of wheelchair options, including ones which are difficult to provide in an unpowered manual chair, but have the disadvantage of significant extra weight. Where an ultra-lightweight manual chair may weigh under 10 kg, the largest outdoor power-chairs may weigh 200 kg or more.Smaller power chairs often have four wheels, with front or rear wheel drive, but large outdoor designs commonly have six wheels, with small wheels at front and rear and somewhat larger powered wheels in the centre.A power-assisted wheelchair is a recent development that uses the frame & seating of a typical rigid manual chair while replacing the standard rear wheels with wheels of similar size which incorporate batteries and battery-powered motors in the hubs. A floating rim design senses the pressure applied by the users push & activates the motors proportionately to provide a power assist. This results in the convenience, and small size of a manual chair while providing motorised assistance for rough/uneven terrain & steep slopes that would otherwise be difficult or impossible to navigate, especially by those with limited upper-body function.

As the wheels necessarily come at a weight penalty it is often possible to exchange them with standard wheels to match the capabilities of the wheelchair to the current activity.Mobility scootersshare some features with powerchairs, but primarily address a different market segment, people with a limited ability to walk, but who might not otherwise consider themselves disabled. Smaller mobility scooters are typically three wheeled, with a base on which is mounted a basic seat at the rear, with a control tiller at the front. Larger scooters are frequently four-wheeled, with a much more substantial seat.Opinions are often polarized as to whether mobility scooters should be considered wheelchairs or not, and negative stereotyping of scooter users is worse than for manual or powerchair users. Some commercial organisations draw a distinction between powerchairs and scooters when making access provisions due to a lack of clarity in the law as to whether scooters fall under the same equality legislation as wheelchairs.Single-arm drive wheelchairsOne-arm or single arm drive enables a user to self-propel a manual wheelchair using only a single arm.

The large wheel on the same side as the arm to be used is fitted with two concentric handrims, one of smaller diameter than the other. On most models the outer, smaller rim, is connected to the wheel on the opposite side by an inner concentric axle. When both handrims are grasped together, the chair may be propelled forward or backward in a straight line. When either handrim is moved independently, only a single wheel is used and the chair will turn left or right in response to the handrim used. Some wheelchairs, designed for use by, provide a similar function by linking both wheels rigidly together and using one of the footplates to control steering via a linkage to the front caster.Reclining wheelchairsReclining or tilt-in-space wheelchairs have seating surfaces which can be tilted to various angles. The original concept was developed by an orthotist, Hugh Barclay, who worked with disabled children and observed that postural deformities such as scoliosis could be supported or partially corrected by allowing the wheelchair user to relax in a tilted position. The feature is also of value to users who are unable to sit upright for extended periods for pain or other reasons.

Various designs are now available and wheelchairs with the feature may either tilt the seat-back and legrests in relation to the seat, or may tilt the entire back, seat and leg rest as one, depending on the need of the user.Standing wheelchairsA is one that supports the user in a nearly standing position. They can be used as both a wheelchair and a, allowing the user to sit or stand in the wheelchair as they wish. Some versions are entirely manual, others have powered stand on an otherwise manual chair, while others have full power, tilt, recline and variations of powered stand functions available. The benefits of such a device include, but are not limited to: aiding independence and productivity, raising self-esteem and psychological well-being, heightening social status, extending access, relief of pressure, reduction of pressure sores, improved functional reach, improved respiration, reduced occurrence of, improved flexibility, help in maintaining density, improved passive range motion, reduction in abnormal muscle tone and spasticity, and skeletal deformities. Other wheelchairs provide some of the same benefits by raising the entire seat to lift the user to standing height.Sports wheelchairsA range of have been developed for disabled athletes, including,. The wheelchairs used for each sport have evolved to suit the specific needs of that sport and often no longer resemble their everyday cousins. They are usually non-folding (in order to increase rigidity), with a pronounced for the wheels (which provides stability and is helpful for making sharp turns), and often are made of composite, lightweight materials.

Even seating position may be radically different, with racing wheelchairs generally used in a kneeling position. Sport wheelchairs are rarely suited for everyday use, and are often a 'second' chair specifically for sport use, although some users prefer the sport options for everyday. Some disabled people, for instance lower-limb amputees, may use a wheelchair for sports, but not for everyday activities. US versus France, FIPFA World Cup, Tokyo, Japan, October 2007 Powerchair football/power soccerWhile most wheelchair sports use manual chairs, at least one sport has been developed for powerchair users. Powerchair football/.Wheelchair stretchersWheelchair stretchers are a variant of wheeled stretchers/gurneys that can accommodate a sitting patient, or be adjusted to lie flat to help in the lateral (or supine) transfer of a patient from a bed to the chair or back.

Once transferred, the stretcher can be adjusted to allow the patient to assume a sitting position.All-terrain wheelchairsAll-terrain wheelchairs can allow users to access terrain otherwise completely inaccessible to a wheelchair user. Two different formats have been developed. One hybridises wheelchair and mountain bike technology, generally taking the form of a frame within which the user sits and with four mountain bike wheels at the corners. In general there are no push-rims and propulsion/braking is by pushing directly on the tyres.A more common variant is the beach wheelchair which can allow better mobility on beach sand, including in the water, on uneven terrain, and even on snow.

The common adaptation among the different designs is that they have extra-wide balloon wheels or tires, to increase stability and decrease ground pressure on uneven or unsteady terrain. Different models are available, both manual and battery-driven. In some countries in Europe, where is well established, many beaches have wheelchairs of this type available for loan/hire.Self-balancing wheelchairs IntroductionThis term refers to the seat-kit of a wheelchair, which is part of the wheelchair that can be adapted to powered transport devices, enabling people to remain seated and navigate safely and comfortably. These devices offer features which conform to special requirements taking into account the aforementioned physical limitations for those with physical challenges. However, self-balancing wheelchairs can be used by anyone preferring to sit while riding a powered transport device.Also referred to as a 'hands-free wheelchair', the self-balancing wheelchair is a new term coined to describe an important piece of equipment for people living with disabilities. Paralysis, either caused by spinal cord injury or otherwise, can produce impairments to the use of the lower limbs, and affects balance due to lack of core-muscle strength. Essentially, when referring to a self-balancing wheelchair, we are talking about essentially a 'seat kit' that attaches to a segway type of mobile device, allowing someone who normally rides in a wheelchair, to ride a powered vehicle themselves.

Typically, a 'segway' is stood upon.but seat kits are made for people who cannot stand up.When a person’s “core” trunk muscles are not functioning, the person cannot adopt certain postures, balance, or movements such as standing, twisting, or reaching. Often, they require wheelchairs for mobility. Wheelchairs are available as manual or powered, but have many limitations in either case, particularly in regards to what terrain can be accessed. Riding over bumpy, hilly, sandy, or uneven terrain is difficult, tiring, and sometimes impossible to navigate from a standard wheelchair.

New powered transport devices on the market allow for mobility over such difficult types of terrain, but they are driven from a standing posture and this precludes anyone who cannot stand up unassisted.HistorySelf-balancing mobility devices were originally designed to be driven by standing on the device and adjusting your center of gravity, forward or backwards, to propel yourself forward or come to a stop. One of the first companies to adapt these self-balancing mobility devices to seated riders, was 'Segseat'. They created the one of the original seats designed for the Segway self-balancing powered mobility device.

These first-generation seat kits attached to a post installed onto the Segway, but they did not perfectly serve the physically-disabled because they did not provide the features required to keep the rider safe while transferring to and from their wheelchair. Recently, more and more inventions are being created and patented. It is this collection of inventions that are making the category of 'self-balancing' wheelchair or 'self-balancing mobility device seat-kits' come alive and come to mean more than simply an alternate form of a wheelchair.Seat-kits were created for use with devices other than the Segway. These other devices are the Ninebot and the Airwheel. However, these seat-kits were not suitable for some people because of the required level of balance and physical core strength needed to remain stable on the seat. These seat kits didn’t include back rests or arm rests. Since the handlebars move independently from the platform, the average user would need to shift their weight with their core and steer with both hands.

This is a critical problem for some users because they might not have enough core strength to control the handlebar by simply sitting, they require one hand on the armrest to shift their weight and the other hand to control the handlebars.Earlier versions of 'self balancing wheelchairs' intended for a four-wheel device to be altered into a two-wheeled device, thus the 'balancing' aspect, and were built differently than the models commonly found now. However the same basic mechanisms and considerations are researched for today's newer models as those in the earlier iterations. For example, performance considerations such as stability, driver dynamic stress, maneuverability and technical requirements are given priority when testing devices. Basic tests include testing the device while in balancing mode or while stationary, testing self-balancing stability when subjected to an impact disturbance, testing movement initiation and stopping while balancing, testing response to impact disturbances while moving; and testing stability on low traction surfaces.DescriptionThe term Self Balancing Wheelchair describes a category of, and is a generic term for devices and modifications that help improve mobility for those with who need to be seated in order to be mobile. Depicts, enhancements to technology, or methods of using technology, that make it possible for physically persons to use or use it more easily, than they were formerly unable to use, or to only use with some difficulty.

Such people typically use wheelchairs or.The Blumil can be ridden with a self-balancing wheelchair seat kitThe Self Balancing Wheelchair, when used as a customized adaptation for a powered mobility transport device, such as a, Ninebot, or, becomes a, and is generally understood as a two-wheeled, self-balancing,.Seating kits are manufactured to be used with self-balancing platforms like the Segway, the Ninebot and the Airwheel, the leading products in the mobility device market. Many of these kits are already being incorporated onto these devices. Most seat kits are available by regional distributors who can install them and customize as necessary.Self Balancing Wheelchairs usually have their mechanics broken down to the following general combination of features: Landing gear for safe and comfortable mounting, dismounting, and transferring to other chairs, handlebars for steering and balancing the device, stability rails on the sides of the seat to hold the rider in place, and controls at arm’s reach of a seated rider requires no leaning over, or body adjustment to steer and brake. These different factors take into account the variety of ways that a user could get injured riding this type of wheelchair, and are therefore implemented as safety features. A chart depicting feature comparisons describes how each platform works, what seat kit to use on each platform, and how to fully customize a self-balancing wheelchair.Types of self-balancing wheelchairs iBOTis a radical power chair developed by that incorporates gyroscopic and active control technology, enabling the chair to balance and run on only two of its four wheels on some surfaces, thus raising the user to standing height. It is also able to climb stairs by leveraging the standing feature. The popular Personal Transporter is a mobility device that was a direct outgrowth of the development of the iBOT wheelchair.

The Segway, which is basically an iBOT with two wheels removed, was developed explicitly to increase the number of units produced and take advantage of the to attempt to make the iBOT affordable to wheelchair users. While popular in concept, the $25,000 iBOT, which was developed as a joint venture between 's and Kamen's, was priced at too high a price point to sustain the needed production and was discontinued in January 2009. On May 21, 2016, announced a partnership with DEKA to produce a new version of the iBOT. No release date was set at the time of the announcement. Smart wheelchairsA smart wheelchair is any powerchair using a to augment or replace. Its purpose is to reduce or eliminate the user's task of driving a powerchair.

Usually, a smart wheelchair is controlled via a, has a suite of and applies techniques in mobile, but this is not necessary. The interface may consist of a conventional wheelchair joystick, a ' device or a touch-sensitive display. This differs from a conventional powerchair, in which the user exerts manual control over speed and direction without intervention by the wheelchair's control system.Smart wheelchairs are designed for a variety of user types. Some are designed for users with, such as, these typically apply collision-avoidance techniques to ensure that users do not accidentally select a drive command that results in a collision. Othersfocus on users living with severe motor disabilities, such as, or with, and the role of the smart wheelchair is to interpret small muscular activations as high-level commands and execute them. Such wheelchairs typically employ techniques from, such as.Technological developmentsRecent technological advances are slowly improving wheelchair and powerchair technology.A variation on the manually-propelled wheelchair is the Leveraged Freedom Chair (LFC), designed by the Mobility Lab. This wheelchair is designed to be low-cost, constructed with local materials, for users in developing countries.

Engineering modifications have added hand-controlled levers to the LFC, to enable users to move the chair over uneven ground and minor obstacles, such as bumpy dirt roads, that are common in developing countries. It is under development, and has been tested in Kenya and India so far.The addition of geared, all-mechanical wheels for manual wheelchairs is a new development incorporating a into the wheel design. The 2-gear wheels can be added to a manual wheelchair. The geared wheels provide a user with additional assistance by providing leverage through gearing (like a bicycle, not a motor). The two-gear wheels offer two speed ratios- 1:1 (no help, no extra torque) and 2:1, providing 100% more hill climbing force. The incorporates an automatic 'hill hold' function which holds the wheelchair in place on a hill between pushes, but will allow the user to override the hill hold to roll the wheels backwards if needed.

The low gear also provides downhill control when descending.A recent development related to wheelchairs is the. They come in a variety of forms, from road and track racing models to off-road types modelled after. While dedicated handcycle designs are manufactured, clip-on versions are available than can convert a manual wheelchair to a handcycle in seconds. The general concept is a clip-on front-fork with hand-pedals, usually attaching to a mounting on the footplate. A somewhat related concept is the Freewheel, a large dolley wheel attaching to the front of a manual wheelchair, again generally to the footplate mounting, which improves wheelchair performance over rough terrain.

Unlike a handcycle, a wheelchair with Freewheel continues to be propelled via the rear wheels.There have been significant efforts over the past 20 years to develop stationary platforms that could enable wheelchair users to exercise as one would on a or.Some devices have been created that could be used in conjunction with virtual travel and interactive gaming similar to an. In 2011, British inventor Andrew Slorance developed Carbon Black the first wheelchair to be made almost entirely out of carbon fibreRecently, 's CNBI project has succeeded in making wheelchairs that can be controlled by brain impulses. A Leveraged Freedom Chair wheelchair user in Kenya. The chair has been engineered to be low-cost and usable on the rough roads common in developing countries.Other variantsFoot propulsion of a manual wheelchair by the occupant is possible for users who have limited hand movement capabilities or simply do not wish to use their hands for propulsion. Foot propulsion also allows patients to exercise their legs to increase blood flow and limit further disability.

Users who do this commonly may elect to have a lower seat height and no footplate to better suit the wheelchair to their needs.Wheelbase chairs are powered or manual wheelchairs with specially seating systems interfaced with them for users with a more complicated. A molded seating system involves taking a cast of a person's best achievable seated position and then either carving the shape from or forming a plastic mesh around it.

This seat is then covered, framed, and attached to a wheelbase.A wheelchair is one designed to support larger weights; most standard chairs are designed to support no more than 250 lb (113 kg) on average.wheelchairs are another available subset of wheelchairs. These can address needs such as being able to play on the floor with other children, or cater for children in large hip-spica casts due to problems such as hip dysplasia.Hemi wheelchairs have lower seats which are designed for easy foot propulsion. The decreased seat height also allows them to be used by children and shorter individuals.A is a related device with some features of a wheelchair and some of walking aids.

Unlike wheelchairs they are only suitable for below knee injuries to a single leg. The user rests the injured leg on the scooter, grasps the handlebars, and pushes with the uninjured leg.Mobility and access.

BuildingsAdapting the built environment to make it more accessible to wheelchair users is one of the key of and local equality legislation such the (ADA). The Social Model of Disability defines 'disability' as the discrimination experienced by people with impairments as a result of the failure of society to provide the adaptions needed for them to participate in society as equals. This includes both physical adaption of the built environment and adaption of organizational and social structures and attitudes. A core principle of access is - that all people regardless of disability are entitled to equal access to all parts of society like public transportation and buildings. A wheelchair user is less disabled in an environment without stairs.Access starts outside of the building, with the provision of reduced height kerb-cuts where wheelchair users may need to cross roads, and the provision of adequate wheelchair parking, which must provide extra space in order to allow wheelchair users to transfer directly from seat to chair.

Some tension exists between access provisions for visually impaired pedestrians and wheelchair users and other mobility impaired pedestrians as textured paving, vital for visually impaired people to recognise the edge of features such as light-controlled crossings, is uncomfortable at best, and dangerous at worst, to those with mobility impairments.For access to public buildings, it is frequently necessary to adapt older buildings with features such as ramps or in order to allow access by wheelchair users and other people with mobility impairments. Other important adaptations can include powered doors, lowered fixtures such as sinks and water fountains, and accessible with adequate space and to allow the disabled person to transfer out of their wheelchair onto the fixture. Access needs for people with other disabilities, for instance visual impairments, may also be required, such as by provision of high visibility markings on the edges of steps and braille labelling. Increasingly new construction for public use is required by local equality laws to have these features incorporated at the design stage.The same principles of access that apply to public buildings also apply to private homes and may be required as part of local building regulations.

Important adaptations include external access, providing sufficient space for a wheelchair user to move around the home, doorways that are wide enough for convenient use, access to upper floors, where they exist, which can be provided either by dedicated wheelchair lifts, or in some cases by using a stairlift to transfer between wheelchairs on different floors, and by providing accessible bathrooms with showers and/or bathtubs that are designed for accessibility. Accessible bathrooms can permit the use of mobile shower chairs or to facilitate bathing for people with disabilities. Wet rooms are bathrooms where the shower floor and bathroom floor are one continuous waterproof surface. Such floor designs allow a wheelchair user using a dedicated shower chair, or transferring onto a shower seat, to enter the shower without needing to overcome a barrier or lip.The construction of and is increasingly required by law, whereas the use of inaccessible features such as in public buildings without any alternative methods of wheelchair access is increasingly deprecated. Modern architecture is increasingly required by law and recognised good practise to incorporate better accessibility at the design stage.In many countries, such as the UK, the owners of inaccessible buildings who have not provided permanent access measures are still required by local equality legislation to provide 'reasonable adjustments' to ensure that disabled people are able to access their services and are not excluded. These may range from keeping a portable ramp on hand to allow a wheelchair user to cross an inaccessible threshold, to providing personal service to access goods they are not otherwise able to reach.VehiclesPublic transit vehicles are increasingly required to be to people who use wheelchairs.In the, all single deck buses are required to be accessible to wheelchair users by 2017, all double-deck coaches by 2020.

Similar requirements exist for trains, with most trains already incorporating a number of wheelchair-spaces.The EU has required airline and airport operators to support the use of airports and airliners by wheelchair users and other 'Persons with Reduced Mobility' since the introduction of EU Directive EC1107/2006.In there is a program to remove a small amount of seating on some trains to make more room for and wheelchairs.' S entire bus system is wheelchair-accessible, and a multimillion-dollar renovation program is underway to provide elevator access to many of the city's 485 subway stations.In, all public transport has provision for at least two wheelchairs per bus, tram or train. In addition all trains have space available for bicycles.The Metro system features complete accessibility on all its subways and buses.In, the entire bus network, i.e.

60 lines, has been accessible to wheelchair users since 2010.In the United States a wheelchair that has been designed and tested for use as a seat in motor vehicles is often referred to as a 'WC19 Wheelchair' or a 'transit wheelchair'. ANSI-RESNA WC19 (officially, SECTION 19 ANSI/RESNA WC/VOL. 1 Wheelchairs for use in Motor Vehicles) is a voluntary standard for wheelchairs designed for use when traveling facing forward in a motor vehicle. ISO 7176/19 is an international transit wheelchair standard that specifies similar design and performance requirements as ANSI/RESNA WC19.Distribution organizationsSeveral organizations exist that help to give and receive wheelchair equipment. Organizations that accept wheelchair equipment donations typically attempt to identify recipients and match them with the donated equipment they have received.

Organizations that accept donations in the form of money for wheelchairs typically have the wheelchairs manufactured and distributed in large numbers, often in developing countries. Organizations focusing on wheelchairs include, the, the and.Seating systemsWheelchair seating systems are designed both to support the user in the sitting position and to redistribute pressure from areas of the body that are at risk of. For someone in the position, the parts of the body that are the most at risk for tissue breakdown include the,. Wheelchair cushions are the prime method of delivering this protection and are nearly universally used. Wheelchair cushions are also used to provide stability, comfort, aid posture and absorb shock.
