Electric Wheelchair With Joystick Joysticks for power wheelchairs can enhance their use and independence Standardized joysticks may not accommodate the unique features of hand dysfunction This study evaluated the efficacy and satisfaction of customizing power wheelchair joysticks fabricated with 3D printing technology Evaluation was conducted using the modified powermobility inside driving assessment PIDA National Aeronautics and Space Administration Task Load Index and Psychosocial Impact of Assistive Devices Scale Control The control system for a power chair includes two essential components the joystick and the electronics Standard joysticks often mount to either the left or right side of the chair while more complex rehab chairs may include swingaway mounts that allow the joystick to be moved to the middle of the seat The manner in which the joystick is placed and used is vital to its effectiveness for a client If a person has a lot of tremors it is important to design the joystick so that the movements dont cause the chair to move accidentally Standard EPW joysticks use proportional input devices that react to the amount deflection of the gimbal in order to control the chairs movements similar to an electronic game controller or automobile accelerator pedal There are many alternative control options for power wheelchairs which require a minimum of force to activate These include switches sip and puff controls head array systems and chin controls Some of these controls require an additional interface to connect to the wheelchair However a lot of them can be used with new joysticks which incorporate Bluetooth into the handles Some standard wheelchair joysticks have a screen to show the condition of the system and also to give feedback to users This is particularly useful for people who are cognitively or visually impaired Some advanced joysticks can control various accessories including environmental controls a TV and tablet No matter what technology is used a joystick is only as effective if it is easy for the user to use For this reason it is crucial to think about the size and positioning of the buttons on a joystick to ensure they are easy to access It is also essential to think about the sensitivity of the joystick that can be set to a range of levels based on the needs of each client Comfort A joystickcontrolled wheelchair comes with many advantages that a manual chair does not offer They reduce fatigue due to operational factors and can travel for longer distances than manually operated chairs Additionally they can be used in places with fewer spaces and more challenging terrain than a manual wheelchair for example outdoor slopes or uneven surfaces This additional freedom allows users to experience an entirely new freedom of movement and a feeling of independence There are a variety of powered wheelchairs that are available each with their own unique features The amount of bells and whistles available on a specific model will depend on the users needs and wants Some of the most common features include Controls on an electric wheelchair equipped with a joysticks can be adapted to meet your individual requirements This includes the type and location of the knob ball or handle Some joysticks are mounted on the top of the dominant armrest while others are placed in the front or back of the seat to allow easy access by an attendant They can also be placed on the sides of the seat for people with limited shoulder range or muscle weakness Other features are more personal to you like the size and style of the joystick display screen Some are backlit or in colors that are easier to read for those who have low vision Other models have additional modes that provide audio or visual cues for navigation They can also offer clocks odometers and battery charge indicators A joysticks ability to maneuver in a limited turning radius is also important The best models will have a small turning radius which makes it easier to maneuver through obstacles and narrow spaces such as hallways The narrow turning radius allows for easier maneuvering in public spaces and in stores This tight turning radius is particularly useful for people who suffer from mobility issues like cerebral palsy multiple sclerosis ALS Huntingtons disease spinal cord injury or brainstem stroke Safety Power wheelchairs were created with safety as the top priority They have robust brake systems that can reduce the speed quickly when the consumer presses the joystick control The chairs also come with antitip rear wheels that stop the chair from tipping forward The most commonly used type of joystick is a proportional control which is similar to automobile accelerator pedals and video game controllers in that the more the joystick is moved away from its center the more quickly the wheelchair moves Joysticks that are proportional require a strong hand and a healthy sense of proprioception Standard joysticks are mounted on the armrest However there are many special controls that place the control on the side or middle of the seat Even with specialized rigging some people might not be able to deflect a handle People with spasticity might have a problem because their muscles can become stiff or atrophy In these instances a head control unit that converts the movement of a consumers head into the required instructions for the wheelchair may be a better option The size and position of the joysticks buttons is another aspect to consider If the buttons are too far in the front or difficult to reach they can interfere with the seating position of the user and cause a strain on the hands On the other hand if the joystick is located too far backwards it could be difficult to turn the wheels or move the chair into tight spaces The seatbelt should be secured on an electric wheelchair Seatbelts must always be fastened when using an electric wheelchair The most powerful wheelchairs can travel as fast as 8mph It is also crucial to charge batteries frequently and every at night if you can This will allow them to live longer and help maintain their effectiveness Its also a good idea to get regular maintenance for your chair to make sure all parts are working properly Accessories Joysticks are the most important component of power wheelchairs and can be improved by adding a variety These range from basic switches to more advanced interfaces that connect to communication devices or even external environmental control units Power wheelchairs with higher end features will typically include a variety of controller components that can satisfy the needs of different clients For example an unexpandable controller will typically only accept a proportional joystick as an input device whereas an expandable controller may allow puff and sip controls special switches and head array systems Some advanced controllers are able to use up to two power seating actuators that are able to adjust the seats position and tilt of the seat The most basic type of joystick that is commonly used in the clinic is a proportional control also called a movement sensing joystick This type of joystick responds to the force by increasing output ie The speed of the wheelchair increases as the stick moves away from the center This requires a good amount of proprioception that is intact and dexterity to be able to use the wheelchair While the technology in use today is able to compensate for minor magnitude movements that occur during EPW driving it is still unable to detect and adjust to more severe unintentional movements such as those caused by greater magnitude tremors or other involuntary movements that are not accompanied by conscious intention such as athetosis5 Until we can create and implement new technologies that can accurately detect and adapt to these kinds of unintentional movements a lot of people suffering from conditions such as athetosis MS ALS or spinal cord injury will not be able safely to use an electric power chair Most wheelchairs have a number of parameters that can be programmed and customised usually with the help of a medical professional These parameters could include altering the torque that is provided by the motor adjusting the speed at which the chair moves and setting the dead zone that is the area within which the EPW cannot produce an output Some controllers allow the clinician to save backup programs This is beneficial in an emergency situation or when the symptoms of a patient change
