Electric Wheelchair With Joystick
Joysticks on power wheelchairs can greatly increase independence and ease of use. However, standardized joysticks can lack accommodation of individualized features of hand impairment.
This study assessed the effectiveness and satisfaction of customizing power wheelchair joysticks that were made using 3D printing technology. Modified power-mobility indoor driving assessment (PIDA), National Aeronautics and Space Administration task load index, and the psychosocial impact of assistive devices scales were used for evaluation.
Control
The control system of a power wheelchair includes two important aspects that are the joystick and electronics (also called the controller). Joysticks that are standard are placed on either the left or right side of the chair, while more complicated rehab chairs have swing-away mounts that permit the joystick to move into the middle of the seat.
The way a joystick will be mounted and used is crucial to its performance for a client. For instance in the case of someone who has significant tremors, it is crucial to ensure the joystick is designed such a way that these actions will not cause accidental activations of the chair. Standard EPW joysticks use proportional input devices which respond to the deflection of the gimbal to control the chair's movement (similar to a video game controller or an accelerator in a car pedal).
There are many alternatives to controlling power wheelchairs, which require a minimum of force to activate. These include switches sip and puff control as well as head array systems and the chin control. Some of these controls require an additional interface to connect to the wheelchair. However, a lot of them can be used with new joysticks that incorporate Bluetooth into the handles.
Some standard wheelchair joysticks have a screen to show the condition of the system and to give feedback to users. This is especially useful for those who are visually or cognitively impaired. Some advanced joysticks can control many different accessories, including the TV, environmental controls and tablet.
No matter what technology is used, a joystick can only be as effective if it is comfortable for the user operate. It is therefore crucial to consider the size of the buttons and their position on a joystick to make them accessible. Additionally, it is important to think about the sensitivities of the joystick, which can be adjusted to a variety of levels based on the preferences of each client.
Comfort
A joystick-controlled power chair offers many benefits that aren't available with manual chairs. They help reduce fatigue due to operational issues and can travel longer distances than manual chairs. They can also be used in places with fewer spaces and more challenging terrain than a manual wheelchair for example, uneven surfaces or slopes in the outdoors. This additional independence allows users to experience a new freedom of movement and feeling of independence.
A variety of power wheelchairs are available in an array of options. The number of bells and whistles available on the particular model will be contingent on the user's needs and desires. A few of the most commonly used features are:
Controls on an electric wheelchair equipped with a joystick can be customized to meet the needs of each individual. This includes the kind of knob or handle, or ball, and the manner in which it is mounted. Some joysticks are mounted on the top of the dominant armrest while others are placed in the front or back of the seat to facilitate access by a person who is. Some joysticks can be positioned on the side for people who have limited shoulder mobility or a weakness in their muscles.
Other features can be more customized, such as the style and size of the joystick's display. Some models are backlit or have colors that are more accessible for those with poor vision. Some models also have auxiliary modes that offer audio or visual clues to help navigate. They can also offer clocks, odometers, as well as indicator of battery charge.
Another important aspect of the joystick is how it can be operated within an area with a tight turning radius. The most efficient models will have a precise turning radius, which allows for easier navigation of obstacles in tight spaces, like hallways. The narrow turning radius makes it easier to maneuver through public areas and stores. This tight turning circle is especially useful for people who have mobility issues, like cerebral palsy, or other mobility issues such as multiple sclerosis, ALS and Huntington's Disease, spinal cord injury or brainstem stroke.
Safety
Power wheelchairs are designed with safety in mind. They are equipped with reliable brake systems that can limit the speed rapidly when the consumer presses the joystick control. The chairs are also equipped with anti-tip rear wheels that prevent the chair from tipping forward.
The most popular 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 center, the speed at which the wheelchair moves. Joysticks that are proportional require a strong hand and good proprioception to operate. The standard joysticks are positioned on the armrest. However there are many special controls that place the control on the middle or side of the seat.
Even with specialized rigging certain people may not be able to turn 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 is possible to use a head control device that converts the movement of a user's head into a instruction for the wheelchair could be a better choice.
The size and position of the joystick's buttons is another aspect to consider. If the buttons are too far forward or are difficult to reach, it could affect the user's position and put strain 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 must always be used with a seatbelt secured. The most powerful wheelchairs can travel at speeds up to 8 mph, and an unfastened seatbelt could result in serious injuries or death. It is also crucial to ensure that batteries are charged regularly, at least every at night, if you can. This will help them to have a longer life and maintain their effectiveness. It's also recommended to perform regular maintenance on your chair to make sure the components are in good working order.
Accessories
The joystick is a key component of any power wheelchair, and there are many accessories that can be added to boost its functionality. They can range from basic switches up to more complex interfaces that connect to communication devices, light electric wheelchairs and even external environment control units. A more expensive power wheelchair usually comes with a variety of controller components that can be used and adjusted to meet the requirements of a particular user. For instance an unexpandable controller will generally only accept a proportional joystick as an input device while an expandable controller may allow puff and sip controls, specialty switches, and head array systems. Some of the advanced controllers can operate up to two power seating actuators, that can alter the direction and angle of the seat.
The most basic kind of joystick used in the clinic is a proportional control, sometimes referred to as a movement sensing joystick. This type of joystick like automobile accelerator pedals and video game controllers responds to the force applied on the stick by increasing its output (i.e. wheelchair speed) the further the stick is moved from center. This requires a good deal of dexterity as well as a strong proprioception to be able to use it effectively.
While the technology that is in use today can compensate for small magnitude movements that occur in EPW driving, it is still unable to recognize and adjust to many more severe unintentional movements, like those caused by larger magnitude tremors or other involuntary movements that are not associated with conscious intent like athetosis.5 As long as we don't create and implement new technologies that can accurately detect and adapt to these kinds of unintentional movement, many sufferers with diseases such as athetosis, MS, ALS or spinal cord injuries will not be able to safely operate an electric power chair.
Most wheelchairs can be programmed and customized with the assistance of a medical professional. These parameters include changing the torque generated by the motor and altering the speed of the chair. They can also be used to determine the dead zone which is the amount of time that the EPW isn't able to produce output. Certain controllers will also be able to store backup programs, which are handy for a healthcare professional to have on hand in case of an emergency or for patients with varying symptoms.
