Electric Wheelchair With Joystick
Joysticks on power wheelchairs may enhance their use and independence. However, standard joysticks may be incompatible with the individualized features of hand dysfunction.
This study assessed the efficacy and satisfaction of customized power wheelchair Joysticks made with 3D printing. 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 evaluating.
Control
The control system of a power wheelchair includes two essential components which are the joystick as well as the electronics (also known as the controller). The standard joysticks are usually mounted to the left or right sides of the chair. However, more sophisticated rehab chairs might have swing away mounts that allow for the joystick to be moved to the middle of the seat.
The way in which the joystick is placed and used is vital to its effectiveness for a client. For instance when a person has significant tremors, it is essential to ensure that the joystick is designed in such a way that the actions will not cause accidental activations of the chair. Standard EPW joysticks use proportional input devices that react to the amount deflection of the gimbal in order to control the chair's movements (similar to an electronic game controller or a car accelerator pedal).
There are a myriad of alternatives to controlling power wheelchairs that require very little force to activate. These include switches, sip and puff controls as well as head array systems and chin control. While some of these specialty controls require a separate interface to connect them to the wheelchair, most are compatible with the latest generation of joysticks, which have integrated Bluetooth into their handles.
Some wheelchair joysticks have a screen on them to show the status of the system and provide feedback to the user. This is particularly beneficial for people who have cognitive or visual impairments. Other advanced joysticks come with the ability to control a variety of accessories like environmental controls and even a TV or tablet.
Whatever technology is used the joystick will be as effective if the user finds it easy to use. It is therefore important to think about the size of the buttons as well as their placement on a joystick in order to make them accessible. Additionally, it is important to consider the sensitiveness of the joystick which can be adjusted to a range of levels based on the needs of each individual client.
Comfort
A joystick-controlled power wheelchair offers many benefits that aren't accessible with a manual chair. They can reduce fatigue caused by operational issues and can travel for longer distances than manually operated chairs. Additionally, they can be used in places with less space and more difficult terrain than a manual wheelchair, like uneven surfaces or slopes in the outdoors. With this added freedom users will experience a freedom of movement that gives new life to their lives and reminds users of the feeling to be independent again.
A variety of different powered wheelchairs are available with many options. The number of bells and whistles a particular model has will depend on the preferences of the user and requires. Some of the most popular features include:
Controls that can be customized on an electric wheelchair equipped with a joystick can be made to meet individual needs. This includes the kind of knob or handle, as well as the ball or the way it is mounted. Some joysticks can be found at the end of the armrests of the driver's seat and others are positioned in the front or back of the seat to make it easier for the an attendant to reach. Some joysticks can be mounted on the more info side of the seat for those who have limited shoulder mobility or muscle weakness.
Other features are more personalised, such as the style and size of the here joystick screen. Certain models are backlit or have a color that makes it easier for those with poor vision to read. Some models have auxiliary modes which provide audio or visual navigation signals. They can also offer clocks, odometers, and battery charge indicators.
Another important aspect of the joystick is how it can be operated within an area with a tight turning radius. The best models will have a narrow turning radius, making it easier to maneuver around obstacles and narrow spaces like hallways. The narrow turning radius allows for easier maneuvering through 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 were made with safety in mind as a priority. They have braking systems that are reliable that reduce speed rapidly when the user presses the joystick control lever. The chairs also have anti-tip rear wheels that stop the chair from tipping forward.
The most common joystick type is a proportional control. It is similar to video game controllers as well as accelerator pedals for cars, in that it makes the wheelchair move faster the further it is from the center. Joysticks that are proportional require a strong hand and good proprioception to operate. A standard joystick is mounted on the armrest, however, a variety special controls are available to mount the control in the middle or on the side of the seat.
Some consumers may not have enough strength to deflect a joystick's handle even with the aid of special rigging. This could be the case with some people with spasticity, and this can cause muscles to stiffen or even die (atrophy). In these instances, it may be better 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 joystick's buttons is another aspect to be considered. If the buttons are far in the front or difficult to reach, they may interfere with the position of the user, and cause an injury to the hands. If the joystick is placed too far back, it may be difficult to move the chair or turn the wheels.
Lastly, an electric wheelchair should always be operated with a seatbelt that is fastened. Seatbelts must be secured when using an electric wheelchair. The fastest wheelchairs can travel as fast as 8mph. It is also crucial to keep batteries charged regularly, at least every at night, if you can. This will allow them to live longer and help maintain their effectiveness. It's also recommended to perform regular maintenance on your chair to ensure all parts are working properly.
Accessories
Joysticks are a key component of power wheelchairs and can be enhanced by a variety of accessories. These range from basic switches to more advanced interfaces that can be connected to communication devices, or external environmental control units. A high-end power wheelchair is likely to have a variety of controller components that can be utilized and configured to meet the requirements of a specific client. A non-expandable control will only accept a proportional stick as an input device while an expandable one will also accept sip and puff controls, specialty switches, and head array systems. Some of the more sophisticated controllers can even use up to two power seating actuators that are able to adjust the position and tilt of the seat.
The most commonly used type of joystick prescribed in clinics is a proportional joystick, also known as a motion-sensing joystick. This type of joystick similar to accelerator pedals in cars and video game controllers responds to the force that is exerted on the stick by increasing its output (i.e. wheelchair speed) as the stick is moved from center. This requires a fair amount of proprioception that is intact and dexterity for efficient use.
The technology that is used today can compensate for minor movements in amplitude during EPW driving. However, it cannot recognize and adjust for more extreme unintentional motions like those that cause higher amplitude tremors or involuntary movements not associated with conscious intention like athetosis.
Most wheelchairs have a range of different parameters that can be programmed and customized usually with the assistance of a physician. These parameters include changing the torque provided by the motor, and adjusting the speed of the chair. They can also be used to set the dead zone which is the area at which the EPW isn't able to produce output. Some controllers also website permit the clinician to store backup programs. This is helpful in an emergency or if a patient's symptoms change.
