Electric Wheelchair With Joystick Joysticks on power wheelchairs may enhance their use and independence However standard joysticks might not accommodate the specific needs of hand impairment This study evaluated the efficacy and satisfaction of customdesigned power wheelchair joysticks that were made using 3D printing technology The evaluation was conducted using the modified powermobility assessment PIDA National Aeronautics and Space Administration Task Load Index and Psychosocial Impact of Assistive Devices Scale Control The control system of a power wheelchair includes two important aspects the joystick and the electronics also called the controller The standard joysticks are usually mounted to either the left or right side of the chair whereas more sophisticated rehab chairs might have swing away mounts that allow for the joystick to be moved into the centre of the seat The way that a joystick is mounted and used will play a crucial role in determining whether it will be effective for a specific user If a client has a high number of tremors it is important to design the joystick such that the movements dont activate the chair accidentally Standard EPW joysticks are proportional input devices that react to the amount deflection of the gimbal to control the chairs motion similar to a video game controller or an accelerator in a car pedal However there are now several different control options available for power wheelchairs that require very minimal force to activate These include switch controls sip and puff controls as well as head array systems and chin control Certain of these control systems require an additional interface to connect to the wheelchair However a lot of them work with new joysticks which incorporate Bluetooth into the handles Some standard wheelchair joysticks have a screen to show the state of the system and also to provide feedback to the users This can be especially beneficial for those who are cognitively or visually impaired Other joysticks with advanced technology have the capability of controlling various accessories including environmental controls and even a TV or tablet Regardless of the technology a joystick can only be useful if its comfortable for the user use Therefore it is essential to consider the size and position of the joysticks buttons to ensure they are easy to access Additionally it is important to think about the sensitiveness of the joystick which can be adjusted to a range of levels based on the needs of each individual user Comfort A joystickcontrolled power wheelchair provides many advantages that arent available with a manual chair They minimize fatigue triggered by operational factors and allow for longer travel distances over manual wheelchairs They can also be used in areas with fewer spaces and more challenging terrain than a manual wheelchair for example outdoor slopes or uneven surfaces With this added independence users can experience the freedom of movement that breathes new life into their lives and reminds them of how great it is to be able to move around independently A variety of different powered wheelchairs are available with many options The amount of bells and whistles available on a specific model will depend on the needs of the user and desires A few of the most commonly used features include Controls that can be customized on an electric wheelchair equipped with the joystick is a possibility to meet individual needs This includes the kind of knob ball or handle and the manner in which it is mounted Some joysticks are positioned on the end of the armrest that is dominant while others are located either on the back or front of the seat to allow easy access by the attendant They can also be placed on the side of the seat for those with limited shoulder range or muscle weakness Other features are more personalised like the design and size of the joysticks screen Some models are backlit or have the color of the screen which makes it easier for those who have low vision to read Some models have extra modes that offer audio or visual navigation signals They also include clocks odometers and battery charge indicators A joysticks ability to maneuver in a limited turning radius is also crucial The best models will have a smaller turning radius which makes it easier to maneuver around obstacles and narrow spaces such as hallways This narrow turning radius allows for easier navigation through public spaces and stores This tight turning circle is particularly beneficial for those with mobility issues like cerebral palsy or other issues with mobility like multiple sclerosis ALS and Huntingtons Disease brainstem injury or spinal cord stroke Safety Power wheelchairs are designed with safety in mind They have robust brake systems that can limit the speed quickly when the user presses the joystick control They also have antitip wheels in the rear to prevent the chair from tipping backward The most common joystick type is a proportional control It is similar to video game controllers and automobile accelerator pedals in that it moves the wheelchair faster the further it is from the center Joysticks that require finger dexterity and intact proprioception to operate A standard joystick is usually mounted on the armrest however a variety of special controls are available to put the controls in the middle or on the side of the seat Some consumers may not have enough strength to deflect a joysticks handle even with the aid of special rigging This is the case with some people who suffer from spasticity which can cause muscles to stiffen or waste away atrophy In these instances a head control unit that transforms the movement of the users head into a instructions for the wheelchair may be a better option Another thing to take into consideration is the size and placement of the joysticks buttons If the buttons are too far to the left or difficult to reach it could affect the users seating position and result in strain on their hands If the joystick is placed too far back it could be difficult to move the chair or turn the wheels Finally an electric wheelchair must always be used with the seatbelt fastened Seatbelts must be secured when using an electric wheelchair The most powerful wheelchairs can travel up to 8mph Batteries should be charged regularly and preferably every night This will ensure they have longer life and keep their efficiency Its also an excellent idea to schedule regular maintenance on your chair to ensure that all components are functioning properly Accessories Joysticks are a key component of power wheelchairs They can be improved by adding a variety These range from simple switches to more advanced interfaces that can be connected to communication devices or external environmental control units Higherend power wheelchairs will often include a variety of controller components that can meet the requirements of different users A nonexpandable control can only accept the proportional stick as an input device however an expandable control can also take sip and puff controls and special switches as well head array systems Certain advanced controllers are able to operate up to two power seating actuators which can adjust the angle and position of the seat The most popular type of joystick used in clinics is a proportional joystick also known as a movementsensing joystick light weight electric wheelchair of joystick responds to the force by boosting output ie wheelchair speed the farther the stick is moved away from the center This requires a good deal of dexterity and intact proprioception for effective use Although the technology used today can be used to compensate for small variations in amplitude in EPW driving but it is not able to detect and adjust to more severe unintentional movements such as those caused by higher magnitude tremors or other involuntary movements that are not associated with conscious intention such as athetosis5 In the meantime until we develop and implement new technology that can reliably detect and adapt to these kinds of unintentional movement many people with conditions like athetosis MS ALS or spinal cord injury will not be able safely to use an electric power chair The majority of wheelchairs can be customised and programmed by a medical professional These parameters can be used to alter the torque provided by the motor and adjusting the speed of the chair They can also be used to determine the dead zone which is the distance in which the EPW isnt able to produce output Certain controllers will also have the ability to store backup programs which can be useful for a healthcare professional to keep in case in the event of an emergency or clients with varying symptoms
