Electric Wheelchair With Joystick
Joysticks on power wheelchairs can significantly increase independence and ease of use. Standardized joysticks may not accommodate the unique characteristics of hand dysfunction.
This study examined the efficacy and satisfaction of customized power wheelchair joysticks made using 3D printing technology. Evaluation was conducted using the modified power-mobility assessment (PIDA), National Aeronautics and Space Administration Task Load Index and Psychosocial Impact of Assistive Devices Scale.
Control
The control system for a power chair has two key components: the joystick, and the electronics. The standard joysticks are usually mounted on the left or right sides of the chair, while more advanced rehab chairs could have swing away mounts that allow the joystick to be positioned in the middle of the seat.
The way the joystick is placed and used is vital to its success for a client. If a client is prone to tremors, it is important to design the joystick such that the movements do not activate the chair accidentally. Standard EPW joysticks generally use proportional input devices, which respond to the level of deflection on the gimbal to regulate the movement of the chair (similar to an automobile accelerator pedal or video game controller).
However, there are now a number of different alternative control options available for power wheelchairs that require minimal force to activate. These include switches, sip and puff controls as well as head array systems and the chin control. Certain of these controls require an additional interface to connect to the wheelchair. However, many of them can be used with new joysticks that incorporate Bluetooth into the handles.
Some of the standard wheelchair joysticks come with a screen to display the current status of the system and provide feedback to the user, which is especially useful for those with cognitive or visual impairments. Other joysticks with advanced technology have the ability to control a variety of accessories like environmental controls and even a TV or tablet.
No matter what technology is employed the joystick will be as effective as the user feels comfortable to use. It is therefore important to consider the dimensions of the buttons and their location on the joystick to make them easily accessible. It is also essential to think about the sensitivity of the joystick that can be set to a variety of levels depending on the individual needs of the client.
Comfort
A joystick-controlled powerchair offers many benefits that aren't offered by manual chairs. They limit fatigue caused by operational factors and permit longer travel distances than manual-operated counterparts. They can also be used in areas with less space or terrain that is more difficult like slopes outdoors and uneven surfaces. With this added independence, users can experience an ease of movement that gives new life to their lives and reminds users of the feeling to be independent once more.
A variety of different power wheelchairs are offered with an array of options. The amount of bells and whistles the particular model comes with will depend on what the user prefers and needs. The most commonly used features are:
The control options on an electric chair with the joystick is a possibility to meet the needs of each individual. This includes the design and location of the knob, ball or handle. Joysticks are usually located at the end of the armrest of the driver's seat and others are positioned on the rear or front of the seat to make it easier for the an attendant to reach. They may also be mounted on the side of the seat for people who have limited shoulder mobility or muscles that are weak.
Other features can be more customized, such as the style and size of the joystick screen. Some models are backlit or have colors that make it easier for those who have low vision to read. Certain models come with auxiliary modes which provide audio or visual navigation signals. Other models can include odometers, clocks and indicators of battery charge.
Another important aspect of the joystick is how well it can be operated within narrow turning radius. The most effective models will have a smaller turning radius, which makes it easier to maneuver around obstacles and narrow spaces such as hallways. This tight turning radius allows for easier navigation in public places and in stores. This radius of tight turning is particularly useful for people with mobility issues such as cerebral palsy, MS, ALS Huntington's disease, spinal cord injury, or brainstem stroke.
Safety
Power wheelchairs are designed with safety in mind. They have reliable braking systems that can reduce speed rapidly when the user presses the joystick control lever. They also have anti-tip wheels in the rear that keep the chair from slipping backwards.
The most common type of joystick is a proportional control, which is similar to automobile accelerator pedals as well as video game controllers in that the more the joystick moves away from center the faster 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 specialty controls that mount the control on the side or middle of the seat.
Even with specialized rigging, some consumers may not be able deflect a handle. Certain people who suffer from spasticity could be a bit troubled because their muscles can become stiff or atrophy. In these cases it might be beneficial to use a head-control device that converts the movements of the consumer's body into the appropriate commands for the wheelchair.
Another thing to take into consideration is the size and position of buttons on the joystick. If the buttons are too far to the left or difficult to reach, they can hinder the seating position of the user and create stress on the hands. If the joystick is placed too far back, it may be difficult to move the chair or turn the wheels.
The seatbelt should be secured on an electric small wheelchair wheelchair. The most powerful wheelchairs can travel at speeds of up to 8 miles per hour, and an unfastened seatbelt could result in serious injuries or even death. It is also crucial to charge batteries regularly, every night if possible. This will ensure that they have a longer life and help maintain their effectiveness. You should also keep your chair regularly maintained to ensure that all components are working correctly.
Accessories
The joystick is an essential component of any heavy duty power chair wheelchair and there are many accessories that can be added to boost its capabilities. These range from simple switches to more advanced interfaces that connect to communication devices or external environmental control units. Power wheelchairs with higher end features will typically have a variety of controller components that are able to meet the requirements of various clients. A non-expandable controller will only accept a proportional stick as an input device however, an expandable control can also take sip and puff controls, specialty switches, and head array systems. Certain advanced controllers can operate up to two heavy duty power chair seating actuators which can alter the seat's direction and angle of the seat.
The most basic type of joystick commonly prescribed in the clinic is a proportional control, also called a movement 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. The speed of the wheelchair lightweight electric increases as the stick is moved away from the center. This requires a good amount of proprioception intact and dexterity to be able to use the wheelchair.
While the technology in use today is able to compensate for minor magnitude movements that occur during EPW driving but it is not able to recognize and adapt to many more severe unintentional movements, like those caused by higher involuntary or amplitude tremors that aren't associated with conscious intent like athetosis.5 In the meantime, until we develop and implement new technologies that can reliably detect and adapt to these kinds of unintentional movements, a lot of people with conditions like athetosis, MS, ALS or spinal cord injuries will not be able to safely use an electric power chair.
The majority of wheelchairs can be customized and programmed by an expert. These parameters include changing the torque generated by the motor, altering the speed at which the chair moves and setting the dead zone, which is the distance within which the EPW will not generate an output. Some controllers also allow the clinician to save backup programs. This is helpful in an emergency situation or if a patient's symptoms alter.
