Electric Wheelchair With Joystick
Joysticks in power wheelchairs can greatly increase accessibility and independence. Standard joysticks might not be able to be able to accommodate the unique characteristics of hand dysfunction.
This study assessed the effectiveness and satisfaction of customized power wheelchair joysticks made using 3D printing technology. Modified power-mobility indoor driving assessment (PIDA), National Aeronautics and Space Administration task load index, and psychosocial impact of assistive devices scale were used for evaluation.
Control
The control system of the power chair comprises two key elements: the joystick and the electronics. Joysticks that are standard are placed on either the left or right side of the chair, while more advanced rehab chairs feature swing-away mounts that permit the joystick to move to the middle of the seat.
The manner in which a joystick is mounted and used is vital to its effectiveness for a user. If a user has a high number of tremors, it is essential to design the joystick such that the movements don't cause the chair to move accidentally. Standard EPW joysticks utilize proportional input devices that respond to the 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 control options for power wheelchairs, that require only a little force to activate. These include switch controls, sip and puff controls head array systems, and chin controls. While some of these specialty controls require an additional interface to connect them to the wheelchair, most are compatible with the new generation of joysticks that have integrated Bluetooth into their handles.
Some standard wheelchair joysticks even have a screen on them to display the 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 capability of controlling various accessories, including environmental controls and even a TV or tablet.
No matter what technology is used, a joystick can only be as effective if it is comfortable for the user to operate. This is why it is crucial to think about the size and location of the buttons on a joystick to ensure that they are easily accessible. Additionally, it is important to think about the sensitivities of the joystick, which can be adjusted to a range of levels according to the requirements of each client.
Comfort
A joystick-controlled power wheelchair provides many advantages that aren't offered by manual chairs. They limit fatigue caused by operational factors and allow for longer travel times than manual-operated counterparts. They can be utilized in areas with limited space or more difficult terrain like outdoor slopes and uneven surfaces. This additional independence allows users to experience a new freedom of movement and a feeling of freedom.
A variety of power wheelchairs are offered with an array of options. The quantity of bells and whistles that the particular model comes with will depend on what the user wants and requires. Some of the most common features include:
Controls on an electric wheelchair equipped with a joysticks can be adapted 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 placed at the opposite side of the armrest that is dominant, while others are placed either on the back or front of the seat to facilitate access by an attendant. They may also be mounted on the sides of the seat for people with limited shoulder range or muscles that are weak.
Other features can be more customized like the design and size of the joystick's screen. Some are backlit, or in colors that are more accessible for those with poor vision. Some models feature auxiliary modes which provide audio or visual navigation indicators. They also have clocks, odometers, as well as indicator of battery charge.
Another crucial aspect of the joystick is how it can be controlled in an area with a tight turning radius. The most effective models will have a small turning radius, making it easier to navigate obstacles and narrow spaces, such as hallways. This narrow turning radius allows for easier navigation through public spaces and stores. This tight turning radius is particularly 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 robust brake systems that can limit the speed rapidly when the consumer presses the joystick control. They also have anti-tip wheels at the rear to prevent the chair from tipping forward.
The most popular type of joystick is a proportional control. It is similar to video game controllers and accelerator pedals for cars, in that it accelerates the wheelchair the further the joystick is away from the center. Joysticks that are proportional require a strong hand and good proprioception to operate. Joysticks that are standard are mounted on the armrest. However there are several of special controls that put the controls on the side or middle of the seat.
Even with specialized rigging, some people might not be able deflect the handle. Some people with spasticity may have a problem because their muscles may become stiff or weak. In these cases it might be beneficial to use a head-control unit that converts the movements of the consumer's body into the required commands for the wheelchair.
Another factor to consider is the size and location of buttons on the joystick. If the buttons are too far forward or hard to reach, they can interfere with the seating position of the user, and cause an injury to the hands. On the other hand when the joystick is too far backwards it could be difficult to turn the wheels or maneuver the chair into tight spaces.
Lastly, an electric wheelchair should always be used with the seatbelt fastened. Seatbelts must be secured when using an electric wheelchair. The most powerful wheelchairs can reach speeds of 8mph. Batteries should be charged regularly and preferably every night. This will ensure they have a longer lifespan and maintain their effectiveness. It's also an excellent idea to schedule regular maintenance for your chair to ensure all parts are working properly.
Accessories
Joysticks are the most important element of power wheelchairs and can be enhanced by a variety of accessories. These range from simple switches to more sophisticated interfaces that connect to communication devices or bariatric electric wheelchair uk even external environmental control units. A more expensive power wheelchair will often have various controller components that can be utilised and adjusted to meet the needs of a particular client. A non-expandable control will only accept a proportional stick as an input device, however, an expandable control can also take sip and puff controls and specialty switches, and head array systems. Some of the more advanced controllers are able to operate up to two power seating actuators which can alter the seat's position and angle 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 kind of joystick responds to the force by increasing output (i.e. wheelchair speed) the farther the stick is moved away from center. This requires a good deal of dexterity as well as a strong proprioception for efficient use.
While the technology that is in use today is able to compensate for minor amplitude movements during EPW driving however, it is unable to recognize and adjust to more severe, unintentional movements, such as those caused by greater magnitude tremors or other involuntary movements that aren't associated with conscious intent, like athetosis.5 As long as we don't develop and implement new technologies that can accurately detect and adapt to these kinds of unintentional movements, many sufferers with diseases such as athetosis, MS, ALS or spinal cord injuries will not be able to safely use an electric power chair.
Most wheelchairs can be customised and programmed by a clinician. These parameters include changing the torque generated by the motor, adjusting the speed of the chair and setting the dead zone which is the amount within which the EPW will not generate an output. Some controllers also be able to store backup programs which is useful for a healthcare professional to have on hand in case in the event of an emergency or clients with varying symptoms.
