Electric Wheelchair With Joystick Joysticks for power wheelchairs can increase their ease of use and independence However standard joysticks may lack accommodation of individualized features of hand disorders This study assessed the effectiveness and satisfaction of customized power wheelchair joysticks that were made using 3D printing technology Modified powermobility indoor driving assessment PIDA National Aeronautics and Space Administration task load index and psychosocial impact of assistive devices scale were used for evaluating Control The control system of a power wheelchair comprises two key components the joystick and the electronics also called the controller The standard joysticks are placed on either the left or right side of the wheelchair while more sophisticated rehab chairs come with swingaway mounts that allow the joystick to be moved into the middle of the seat The manner in which a joystick is mounted and used is crucial to its performance for a user If a client has a high number of tremors it is crucial to design the joystick so that the movements do not trigger the chair inadvertently The standard EPW joysticks are typically proportional input devices which react to the amount of deflection on the gimbal to control the movement of the chair similar to an automobile accelerator pedal or video game controller There are a variety of alternatives to controlling power wheelchairs that require very little force to activate Switch controls sipandpuff controls head arrays and chin controls are all available Certain of these controls require an additional interface to connect to the wheelchair However most of them work with new joysticks that integrate Bluetooth into the handles Some wheelchair joysticks are equipped with screens to display the condition of the system and provide feedback to the users This is especially useful for those who are visually or cognitively impaired Certain advanced joysticks are able to control a wide range of accessories such as environmental controls a TV and tablet Whatever technology is used a joystick will only be as useful as the user finds it easy to use For this reason it is essential to consider the size and location of the buttons on a joystick to ensure they are easily accessible Also it is essential to consider the sensitiveness of the joystick which can be adjusted to a range of levels depending on the requirements of each client Comfort A joystickcontrolled wheelchair comes with many advantages that manual chairs do not have They reduce fatigue due to operational issues and are able to travel further than manually operated chairs They can also be used in locations that are smaller and have more difficult terrain than a manual one such as uneven surfaces or slopes in the outdoors With this added independence users can experience a freedom of movement that breathes new life into their lives and reminds them of how great it is to be independent once more A variety of different powered wheelchairs are available in many options The number of bells and whistles available on a specific model will depend on the requirements of the user and their wants Some of the most popular features are Controls on an electric wheelchair with joystick can be customized to meet your individual requirements This includes the design and location of the knob ball or handle Some joysticks are located at the end of the armrest of the drivers seat While others are set in the front or back of the seat to make it easier for the attendants to reach Certain joysticks can be placed on the side of the seat for those who have limited shoulder mobility or muscular weakness Other features are more personal in nature such as the size and shape of the joystick display screen Certain models are backlit or have a color that makes it easier for people who have low vision to read Certain models come with auxiliary modes which provide visual or audio navigation cues Other models may include clocks odometers and indicators for battery charge The ability of a joystick to move in a limited turning radius is also essential The most effective models will have a narrow turning radius which makes it easier to navigate obstacles and narrow spaces like hallways This narrow turning radius makes it easier to navigate through public spaces and stores This narrow turning radius is particularly useful for people who suffer from mobility issues like cerebral palsy MS ALS Huntingtons disease spinal cord injury or brainstem stroke Safety Power wheelchairs were created with safety as a priority They have robust brake systems that can slow the speed quickly when the user presses the joystick control The chairs also have antitip rear wheels to prevent the chair from tipping forward The most popular type of joystick is a proportional control It is similar to video game controllers and accelerator pedals for cars in that it accelerates the wheelchair the further it is from the center These joysticks require finger dexterity and a healthy sense of proprioception Standard joysticks are mounted on the armrest However there are many of special controls that put the control on the middle or side of the seat Even with specialized rigging some people might not be able to turn the handle This may be the case for those who suffer from spasticity which can cause muscles to stiffen or waste away atrophy In these cases it is possible to use a headcontrol device that converts the movements of the consumers body into the commands for the wheelchair Another factor to consider is the size and placement of buttons on the joystick If the buttons are located too far forward or are difficult to reach it can affect the users position and put stress on their hands If the joystick is too far back it may be difficult to maneuver the chair or turn the wheels Lastly an electric wheelchair should always be operated with a seatbelt that is fastened modern electric wheelchairs can reach speeds of up to 8 miles per hour and a seatbelt that isnt fastened can result in serious injuries or death It is also essential to ensure that batteries are charged regularly at least every night if it is possible This will ensure that they have a longer lifespan and maintain their effectiveness Its also a good idea to get regular maintenance for your chair to ensure the components are in good working order Accessories Joysticks are the most important component of power wheelchairs They can be enhanced with a variety of accessories These can range from simple switches to more sophisticated interfaces that connect to communication devices and even external environment control units A higherend power wheelchair is likely to have various controller components that can be utilised and adapted to meet the requirements of a particular user For example a nonexpandable controller will generally only accept the proportional joystick as an input device whereas an expandable controller can allow puff and sip controls special switches and head array systems Some of the more sophisticated controllers can even use up to two power seating actuators which are able to adjust the seats position and tilt of the seat The most basic kind of joystick that is commonly used in the clinic is a proportional control sometimes called a motion sensing joystick This type of joystick like automobile accelerator pedals and video game controllers responds to the force exerted on the stick by increasing its output ie wheelchair speed the farther the stick is moved from center This requires a lot of dexterity as well as a strong proprioception for effective use The technology of today is able to compensate for a small amplitude movement during EPW driving However its not able to detect and adjust for many more serious unintentional movements such as those that result in larger amplitude tremors or involuntary movements that arent caused by conscious intent such as athetosis The majority of wheelchairs have a variety of different parameters that can be programmed or customized usually with the assistance of a medical professional These parameters include changing the torque generated by the motor and adjusting the speed of the chair They can be used to set the dead zone which is the amount of time that the EPW will not produce an output Some controllers also have the ability to store backup programs which is useful for a healthcare professional to keep in the event in the event of an emergency or patients with varying symptoms
