Joysticks on power wheelchairs can greatly increase accessibility and independence. However, standardized joysticks can be incompatible with the individualized features of hand impairment.

This study evaluated the efficacy 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 scale were employed for evaluating.

Control

The control system for the power chair comprises two key components: the joystick, and the electronics. Joysticks that are standard mount on the left or right sides of the chair, while more sophisticated rehab chairs might include swing-away mounts that allow for the joystick to be positioned in the centre of the seat.

The manner in which a joystick is mounted and used is crucial to its performance for a customer. For instance, if an individual suffers from severe tremors, it is crucial to ensure the joystick is designed such a way that the actions will not cause accidental activations of the chair. Standard EPW joysticks are typically proportional input devices that respond to the amount of deflection on the gimbal to determine the direction of the chair (similar to an automobile accelerator pedal or fastest electric Wheelchair video game controller).

There are a variety of alternatives to controlling power wheelchairs, which require a minimum of force to activate. These include switches sip and puff controls head array systems, and the chin control. While some of these specialty controls require a separate interface to connect them to the wheelchair, a lot are compatible with the new generation of joysticks that have incorporated Bluetooth into their handles.

Some standard wheelchair joysticks have a screen to show the status of the system, and to provide feedback to the users. This is particularly useful for people who are cognitively or visually impaired. Other advanced joysticks come with the capability of controlling a variety of accessories like environmental controls, and even a tablet or TV.

Regardless of the technology, a joystick can only be useful if it's comfortable for the user use. This is why it is crucial to think about the size and location of the joystick's buttons to ensure that they are easy to access. It is also important to think about the sensitiveness of the joystick which can be adjusted to a range of levels according to the needs of each individual client.

Comfort

A joystick-controlled power wheelchair has many advantages not accessible with a manual chair. They can reduce fatigue caused by operational issues and can travel longer distances than manually operated chairs. Additionally, lightweight travel electric wheelchair they can be used in locations that are smaller and have more challenging terrain than a manual one, for example, outdoor slopes or uneven surfaces. This additional freedom allows users to experience an entirely new freedom of movement and feeling of independence.

A variety of power wheelchairs are offered with many options. The amount of bells and whistles available on the specific model will depend on the user's needs and wants. A few of the most common features include:

Controls on an electric wheelchair that have a joystick can be customized to meet the needs of each individual. This includes the type of knob or handle, as well as the ball or how it is mounted. Some joysticks are positioned on the top of the armrest that is dominant, while others are placed on the front or back of the seat for easy access by the attendant. They can also be placed on the side of the seat for people with limited shoulder mobility or muscle weakness.

Other features can be more customized like the design and size of the joystick's screen. Some models are backlit, or have the color of the screen, which makes it easier for those with low-vision to read. Some models feature additional modes that provide audio or visual navigation indicators. They also have clocks, odometers, and battery charge indicators.

Another crucial aspect of the joystick is how well it can be controlled in an area with a tight turning radius. The best models will have a tight turning radius, which makes it easier to navigate obstacles in narrow spaces, such as hallways. The tight turning radius also allows for easier maneuvering in public areas and stores. This narrow turning radius is particularly useful for people who suffer from mobility issues like cerebral palsy, multiple sclerosis, ALS 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 reduce speed swiftly when the user presses the joystick control lever. The chairs also come with anti-tip rear wheels to prevent the chair from tipping forward.

The most commonly used type of joystick is a proportional control. It is similar to video game controllers and automobile accelerator pedals in that it moves the wheelchair faster the further the joystick is away from the center. These types of joysticks need proprioception as well as finger dexterity to operate efficiently. The standard joysticks are positioned 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 enough muscle strength to deflect a joystick's handle even with special rigging. This could be the case for some people with spasticity, and this can cause muscles to stiffen or deteriorate (atrophy). In these instances it is possible to utilize a head-control unit that converts the movements of the user's body into the appropriate commands for the wheelchair.

Another aspect to consider is the size and position of buttons on the joystick. If the buttons are located too far forward or are difficult to reach, it could alter the user's sitting position and put stress on their hands. If the joystick is placed too far back, it can be difficult to maneuver the chair or turn the wheels.

Lastly, an electric wheelchair must always be used with the seatbelt fastened. The most powerful wheelchairs can travel at speeds of up to 8 miles per hour and a seatbelt that is not fastened could result in serious injuries or death. It is also important to charge batteries regularly, at least every at night, if you can. This will ensure that they have a longer life and maintain their effectiveness. It is also recommended to have your chair checked regularly to ensure that all components are working correctly.

Accessories

The joystick is a key component of any power wheelchair and there are numerous accessories that may be added to boost its performance. These range from simple switches to more sophisticated interfaces that connect to communication devices or even external environmental control units. A more expensive power wheelchair will often have several controller components that can be utilized and adapted 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 model will also accept sip and puff control, special switches, as well head array systems. Some of the more advanced controllers can also operate up to two power seating actuators, which are able to adjust the position and tilt of the seat.

The most basic type of joystick commonly prescribed in the clinic is an inverse control, often called a motion sensing joystick. This type of joystick, similar to accelerator pedals in cars and video game controllers, responds to the force applied on the stick by increasing its output (i.e. The speed of the wheelchair increases as the stick moves away from the center. This requires a good amount of proprioception intact and dexterity for efficient use.

While the technology in use today is able to compensate for minor magnitude movements that occur in EPW driving but it is not able to recognize and adjust to more severe and unintentional movements, like those caused by greater amplitude tremors or involuntary movements that are not accompanied by conscious intention, such as athetosis.5 In the meantime, until we develop and implement new technology 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 won't be able safely to use an electric power chair.

Most wheelchairs have a number of different parameters that can be programmed and customized, usually with the help of a clinician. These parameters include changing the torque generated by the motor, changing the speed of the chair and setting the dead zone, which is the distance within which the EPW is unable to produce an output. Some controllers permit the clinician to store backup programs. This is helpful in an emergency situation or when the symptoms of a patient change.
