Electric Wheelchair With Joystick Power wheelchairs with joysticks can significantly increase the user's independence and make it easier to use. However, standard joysticks may lack accommodation of individualized features of hand disorders. This study assessed the effectiveness and satisfaction of custom-designed power wheelchair joysticks that were made using 3D printing technology. Evaluation was conducted using the modified power-mobility assessment (PIDA), National Aeronautics and Space Administration Task Load Index, and the Psychosocial Impact of Assistive Devices Scale. Control The control system of a power chair includes two key elements: the joystick and the electronics. Joysticks that are standard are placed on the left or the right side of the chair, while more sophisticated rehab chairs come with swing-away mounts which allow the joystick to slide to the middle of the seat. The manner in which a joystick will be mounted and used is crucial to its performance for a user. If a user is prone to tremors, it is essential to design the joystick such that the movements do not activate the chair accidentally. Standard EPW joysticks generally use proportional input devices that respond to the level of deflection on the gimbal to determine the direction of the chair (similar to an accelerator pedal or video game controller). However, there are now numerous alternative control options available for power wheelchairs that require very little force for activation. These include switch controls sip and puff controls 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 are compatible with new joysticks that incorporate Bluetooth into the handles. Some of the standard wheelchair joysticks have a screen on them to display the current status of the system and provide feedback to the user, which can be particularly useful for people who have visual or cognitive impairments. Other advanced joysticks have the capability of controlling various accessories, including environmental controls, and even a TV or tablet. No matter what technology is employed the joystick will be as effective if the user finds it comfortable to use. Therefore, it is important to consider the size and position of the buttons on a joystick to ensure that they are easy to access. It is also important to consider the joystick's sensitivity that can be set to a range of levels based on the needs of each client. Comfort A joystick-controlled chair has many advantages that a manual chair does not offer. They can reduce fatigue caused by operational issues and can travel for longer distances than manual-operated chairs. They can also be used in areas with less space or more challenging terrain like slopes outdoors and uneven surfaces. This additional independence gives users a new freedom of movement and a feeling of independence. A variety of power wheelchairs are offered with many options. The quantity of bells and whistles a particular model has will depend on the preferences of the user and requires. The most commonly used features include: Controls on an electric wheelchair with joystick can be customized to meet your individual requirements. This includes the type of knob or handle, or ball, and the way it is mounted. Some joysticks can be found on the armrests of the driver's seat While others are set in the front or back of the seat to make it easier for the an attendant to reach. They can also be placed on the sides of the seat for people with limited shoulder mobility or muscle weakness. Other features are more personal to you like the size and shape of the joystick display screen. Some models are backlit or have colors that are more accessible for those with poor vision. Certain models come with auxiliary modes which provide audio or visual navigation indicators. They also have clocks, odometers, as well as indicators of battery charge. Another crucial aspect of the joystick is how well it can be controlled in an area with a tight turning radius. The most effective models will have a small turning radius, which makes it easier to maneuver around obstacles and narrow spaces like hallways. The tight turning radius also makes it easier to maneuver in public areas and stores. This radius of tight turning is especially useful for people with mobility issues such as cerebral palsy, multiple sclerosis ALS, Huntington's disease, spinal cord injury, or brainstem stroke. Safety Power wheelchairs are created with safety as a priority. They have braking systems that are reliable that reduce speed swiftly when the user presses the joystick control lever. The chairs also have anti-tip rear wheels that prevent the chair from tipping forward. The most commonly used type of joystick is a proportional control, which is similar to accelerator pedals as well as video game controllers in that the more the joystick moves away from the center the faster the wheelchair moves. Joysticks that are proportional require a strong hand and intact proprioception to operate. A standard joystick is placed on the armrest however, a variety specific controls are available that mount the controls in the middle or at the sides of the seat. Some consumers may not have enough strength to withstand the force of a joystick, even with the help of special rigging. This may be the case for those who have spasticity, which can cause muscles to become stiff or even die (atrophy). In these instances the use of a head control unit that converts the movement of a user's head into a instruction for the wheelchair could be a better choice. Another thing to take into consideration is the size and placement of the joystick's buttons. If the buttons are too far forward or hard to reach, they may affect the position of the user and create stress on the hands. On the other side when the joystick is placed too far backward it may be difficult to turn the wheels or move the chair through tight spaces. Lastly, an electric wheelchair is best operated with a seatbelt that is fastened. Seatbelts must always be fastened when using an electric wheelchair. The most powerful wheelchairs can reach speeds of 8mph. Batteries should be charged frequently and at least every night. This will ensure that they last longer and help maintain their effectiveness. It is also recommended to have your chair maintained regularly to ensure that all components are operating properly. Accessories Joysticks are the most important component of power wheelchairs and can be improved with a variety of accessories. MyMobilityScooters from basic switches to more advanced interfaces that can connect to communication devices or even external environmental control units. A higher-end power wheelchair will often have various controller components that can be used and adjusted to meet the requirements of a particular client. A non-expandable controller will only accept a proportional stick as an input device while an expandable model can also take sip and puff control, special switches, as well head array systems. Certain advanced controllers can operate up to two power seating actuators which can adjust the angle and position of the seat. The most commonly used type of joystick that is prescribed in clinics is a proportional joystick also known as a motion-sensing joystick. This kind of joystick, similar to accelerator pedals in cars and video game controllers responds to the force exerted on the stick by increasing its output (i.e. The speed of the wheelchair increases as the stick is moved away from the center. This requires a good deal of dexterity and a healthy sense of proprioception for efficient use. While the technology in use today can be used to compensate for small amplitude movements during EPW driving but it is not able to recognize and adapt to many more severe unintentional movements, like those caused by greater amplitude tremors or involuntary movements that aren't associated with conscious intent, like athetosis.5 In the meantime, until we create and implement new technologies that are able to reliably detect and adjust to these types of unintentional movements, many sufferers with diseases such as athetosis, MS, ALS or spinal cord injuries won't be able to safely use an electric power chair. Most wheelchairs can be customised and programmed by an expert. These parameters include changing the torque produced by the motor, altering the speed of the chair and setting the dead zone which is the amount within which the EPW cannot produce an output. Some controllers also have the ability to save backup programs, which are handy for a doctor to keep in the event in an emergency, or for clients with varying symptoms.
