Electric Wheelchair With Joystick
Joysticks on power wheelchairs can increase their ease of use and independence. Standard joysticks are not able to accommodate the unique features of hand dysfunction.
This study assessed the effectiveness and satisfaction of custom-designed power wheelchair joysticks made using 3D printing technology. The test was conducted using 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 comprises two key components that are the joystick and electronics (also known as the controller). Joysticks that are standard are placed on the left or the right side of the wheelchair, while more complicated rehab chairs have swing-away mounts that permit the joystick to move to the middle of the seat.
The way a joystick is mounted and used will play a crucial role in determining if it will be effective for a specific client. For example in the case of someone who suffers from severe tremors, it is vital to ensure the joystick is constructed in such a way that these movements will not trigger accidental activations of the chair. Standard EPW joysticks use proportional input devices which respond to the amount deflection of the gimbal to control the chair's movement (similar to a video game controller or a car accelerator pedal).
There are a variety of alternatives to controlling power wheelchairs, that require a minimum of force to activate. Switch controls, sip-and-puff controls, head arrays, and chin controls are all accessible. While some of these specialty controls require a separate interface to connect them to the wheelchair, most are compatible with the new generation of joysticks that have integrated Bluetooth into their handles.
A few standard wheelchair joysticks come with screens to display the status of the system, and provide feedback to the users. This can be especially beneficial for those who are visually or cognitively impaired. Some advanced joysticks allow for various accessories, including the TV, environmental controls and tablet.
No matter what technology is used, a joystick will only be as useful as the user is comfortable to use. This is why it is crucial to think about the size and positioning of the buttons on a joystick to ensure that they are easily accessible. It is also important to consider the sensitivities of the joystick, which can be adjusted to a variety of levels based on the preferences of each user.
Comfort
A joystick-controlled chair has many advantages that a manual chair does not have. They limit fatigue caused by operational issues and allow for longer travel times over manual wheelchairs. They can be utilized in areas with limited space or more challenging terrain, such as outdoor slopes and uneven surfaces. With this added freedom, users can experience a freedom of movement that breathes new life into their lives and reminds them of how it feels to be independent once more.
A variety of power wheelchairs are available with a wide range of options. The number of bells and whistles included on the specific model will depend on the requirements of the user and their wants. Some of the most popular features include:
The control options on an electric wheelchair equipped with a joystick is possible to satisfy the individual's needs. This includes the kind of knob or handle, or ball, and how it is mounted. Joysticks are usually located on the armrest of the driver's chair and others are positioned on the front or rear of the seat to make it easier for an attendant to reach. Some joysticks can be positioned on the side for people who have limited shoulder mobility or muscular weakness.
Other features are more personal in nature like the size and design of the joystick display screen. Certain models are backlit or have a color that makes it easier for those with low-vision to read. Certain models come with auxiliary modes which provide visual or audio navigation cues. Other models could include odometers, clocks and indicators for battery charge.
The ability of a joystick to move within a narrow turning radius is also crucial. The most effective models will have a small turning radius, making it easier to maneuver through obstacles and narrow spaces like hallways. This radius of tight turning makes it easier to navigate in public areas and stores. This tight turning radius is particularly useful for people who have mobility issues, such as cerebral palsy, MS, ALS, Huntington's disease, spinal cord injury, or brainstem stroke.
Safety
Power wheelchairs have been designed with safety as a top priority. They have reliable brake systems that can limit the speed as quickly as the user presses the joystick control. The chairs are also equipped with anti-tip rear wheels that stop the chair from tipping forward.
The most commonly used type of joystick is a proportional control, which is similar to car accelerator pedals as well as video game controllers in that the more the joystick is moved away from the center the faster the wheelchair moves. These kinds of joysticks require proprioception as well as finger dexterity to work effectively. A standard joystick is placed on the armrest however, a variety of specific controls are available that mount the control in the middle or on the side of the seat.
Even with special rigging, some people might not be able deflect the handle. This could be the case for some people who suffer from spasticity, which can cause muscles to stiffen or even die (atrophy). In these cases it might be beneficial to utilize a head-control unit that converts the movements of the user's body into the commands for the wheelchair.
The size and location of the buttons on the joystick is another factor to be considered. If the buttons are too far forward or hard to reach, they could affect the seating position of the user and create a strain on the hands. On the other hand when the joystick is located too far backward it may be difficult to turn the wheels or maneuver the chair into tight spaces.
Lastly, an electric wheelchair should always be used with a seatbelt secured. Seatbelts must be secured when using an electric wheelchair. The fastest wheelchairs can reach speeds of 8mph. It is also essential to keep batteries charged regularly, at least every night, if it is possible. This will help them to last longer and maintain their effectiveness. You should also have your chair regularly maintained to ensure that all parts are operating properly.
Accessories
The joystick is an essential component of any power wheelchair, and there are numerous accessories that can be added to improve its functionality. These range from basic switches to carbon fibre electric wheelchair more sophisticated interfaces that can be connected to communication devices, or external environmental control units. Higher-end power wheelchairs will often include a variety of controller components that are able to meet the needs of different clients. For example the non-expandable controller would typically only accept a proportional joystick for an input device while an expandable controller may allow for puff and sip controls, specialty switches and head array systems. Some of the more advanced controllers are able to operate up to two power seating actuators, that can alter the angle and position of the seat.
The most popular type of joystick that is prescribed in clinics is a proportional joystick, also known as a motion-sensing joystick. This type of joystick like accelerator pedals for cars and video game controllers responds to the force applied on the stick by increasing its output (i.e. wheelchair speed) the farther the stick is pushed away from the center. This requires a lot of dexterity and intact proprioception to be able to use it effectively.
Although the technology used today can compensate for small amplitude movements in EPW driving, it is still unable to detect and adjust to more severe and accidental movements, such as those caused by larger magnitude tremors or other involuntary movements that are not accompanied by conscious intent like athetosis.5 In the meantime, until we create and implement new technologies that can accurately detect and adapt to these kinds of unintentional movements, many people suffering from conditions such as athetosis, MS, ALS or spinal cord injuries will not be able safely to use an electric power chair.
Most wheelchairs have a range of parameters that can be programmed or customized usually with the assistance of a medical professional. These parameters can include changing the torque produced by the motor, adjusting the speed at which the chair moves and setting the dead zone which is the amount within which the EPW cannot produce an output. Some controllers will also have the ability to store backup programs, which can be useful for a doctor to have in the event in an emergency, or for a client with fluctuating symptoms.
