Electric Wheelchair With Joystick
Joysticks on power wheelchairs can increase their ease of use and independence. However, standardized joysticks can lack accommodation of individualized features of hand impairment.
This study assessed the efficacy and satisfaction of custom-designed power wheelchair Joysticks that were manufactured using 3D printing. Modified power-mobility indoor driving assessment (PIDA), National Aeronautics and Space Administration task load index, and psychosocial impact of assistive devices scales were used for evaluating.
Control
The control system of a power wheelchair includes two important aspects that are the joystick and electronics (also called the controller). The standard joysticks are placed on the left or the right side of the wheelchair, whereas more advanced rehab chairs feature swing-away mounts that allow the joystick to move into the middle of the seat.
The way in which a joystick will be mounted and used is vital to its effectiveness for a client. For example, if an individual suffers from severe tremors, it is vital to ensure the joystick is constructed in such a way that these movements do not trigger accidental activations of the chair. Standard EPW joysticks use proportional input devices which respond to the amount deflection of the gimbal in order to control the chair's motion (similar to the video game controller or a car accelerator pedal).
There are a myriad of alternatives to controlling power wheelchairs that require only a little force to activate. Switch controls, sip-and puff controls head arrays, sip-and-puff controls, and the chin controls are all there. Certain of these controls require an additional interface to connect to the wheelchair. However, a lot of them are compatible with new joysticks which incorporate Bluetooth into the handles.
Some standard wheelchair joysticks even have a screen to display the status of the system and provide feedback to the user, which is particularly beneficial for people who have cognitive or visual impairments. Certain advanced joysticks are able to control a wide range of accessories such as environmental controls, a TV and tablet.
No matter what technology is employed, a joystick can only be as effective if the user is easy to use. It is therefore essential to think about the size of the buttons and their position on the joystick to make them easily accessible. It is also important to think about the sensitivity of the joystick, which can be set to a variety of levels based on the specific needs of the user.
Comfort
A joystick-controlled power wheelchair provides many advantages that aren't offered by a manual chair. They help reduce fatigue due to operational factors and can travel longer distances than manually operated chairs. They can also be used in places with less space and more difficult terrain than a manual one, such as outdoor slopes or uneven surfaces. This increased independence allows users to experience the freedom of movement and a feeling of independence.
A variety of different powered wheelchairs are available with many options. The number of bells and whistles available on the specific model will depend on the needs of the user and wants. The most commonly used features include:
Customization of controls on an electric wheelchair equipped with a joystick can be made to meet the needs of each individual. This includes the type of knob, ball or handle and the way it is mounted. Some joysticks are positioned on the end of the dominant armrest, while others are placed either on the back or front of the seat for easy access by an attendant. They can also be positioned on the sides of the seat for those with limited shoulder range or muscles that are weak.
Other features are more personalized including the design and size of the joystick's screen. Certain models are backlit or have the color of the screen, which makes it easier for people who have low vision to read. Certain models come with extra modes that offer audio or visual navigation indicators. Other models may include odometers, clocks and battery charge indicators.
A joystick's ability to maneuver in a limited turning radius is also crucial. The best models will have a small turning radius, making it easier to navigate obstacles and narrow spaces like hallways. This radius of tight turning allows for easier navigation in public places and in stores. This tight turning radius is especially useful for people who have 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 top priority. They have robust brake systems that can slow the speed quickly when the user presses the joystick control. The chairs are also equipped with anti-tip rear wheels to prevent the chair from tipping forward.
The most common type of joystick is a proportional controller, which is similar to automobile accelerator pedals as well as video game controllers in that the more the joystick is moved away from center, the faster the wheelchair moves. These joysticks require finger dexterity and intact proprioception to operate. Standard joysticks are mounted on the armrest. However, there are a variety of special controls that put the controls on the middle or side of the seat.
Some consumers may not have the strength to deflect a joystick's handle, even with the help of special rigging. This could be the case for those with spasticity, and this can cause muscles to stiffen or even die (atrophy). In these instances it is possible to use a head control device that converts the movement of the user's head into a instructions for the wheelchair may be a better choice.
Another factor to consider is the size and location of buttons on the joystick. If the buttons are located too far to the left or difficult to reach, it could alter the user's sitting position and cause strain on their hands. If the joystick is too far back, it could be difficult to move the chair or turn the wheels.
Additionally, an electric chair is best operated with a seatbelt that is fastened. Seatbelts should always be fastened when using an electric wheelchair. The fastest wheelchairs can travel as fast power chairs for handicapped as 8mph. Batteries must be charged regularly and at least every night. This will ensure that they live longer and maintain their effectiveness. It's also recommended to perform regular maintenance for your chair to ensure that all components are functioning properly.
Accessories
Joysticks are an essential component of power wheelchairs. They can be upgraded with a variety of accessories. These can range from simple switches, to more advanced interfaces that connect to communication devices and even external environment control units. Power wheelchairs with higher end features will typically have a variety of controller components that can meet the needs of different clients. For example the non-expandable controller would generally only accept a proportional joystick as an input device while an expandable controller may allow puff and sip controls, special switches and head array systems. Some of the more advanced controllers can even operate up to 2 power seating actuators that are able to adjust the seat's position and tilt of the seat.
The most popular type of joystick used 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 that is exerted on the stick by increasing its output (i.e. The speed of the wheelchair increases when the stick is moved away from the center. This requires a significant amount of proprioception intact and dexterity to be able to use the wheelchair.
The technology that is used today is able to compensate for a small amplitude movement during EPW driving. However, it's not able to recognize and adjust for more severe unintentional motions, such as those that result in larger amplitude tremors, or involuntary movements that aren't associated with conscious intention like athetosis.
The majority of wheelchairs can be programmed and customized with the assistance of a medical professional. These parameters can be used to alter the torque produced 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 allow the clinician to store backup programs. This is helpful in an emergency situation or if a patient's symptoms change.
