Joysticks on power wheelchairs can enhance their use and independence. Standardized joysticks may not accommodate the unique features of hand disorders.

This study evaluated the efficacy and satisfaction of customized power wheelchair joysticks fabricated with 3D printing technology. The 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 includes two important components: the joystick and the electronic. Standard joysticks are mounted on either the left or right side of the chair, while more sophisticated rehab chairs come with swing-away mounts that permit the joystick to be moved into the middle of the seat.

The manner in which a joystick can be placed and operated is a significant factor in determining whether it will be a success for a specific client. If a person has a lot of tremors it is important to design the joystick in a way that the movements don't trigger the chair inadvertently. Standard EPW joysticks are typically proportional input devices, which react to the amount of deflection of the gimbal to regulate the movement of the chair (similar to an automobile accelerator pedal or video game controller).

There are many alternatives to control options for power wheelchairs, that require only a little force to activate. These include switches sip and puff control, head array systems and chin control. While some of these controls require an additional interface to connect them to the wheelchair, a lot are compatible with the latest generation of joysticks that have incorporated Bluetooth into their handles.

A few standard wheelchair joysticks come with screens that display the status of the system, and also to give feedback to users. This is particularly useful for people who are cognitively or visually impaired. Other advanced joysticks have the ability to control many different devices like environmental controls, and even a tablet or TV.

No matter what technology is used the joystick is useful if it's comfortable for the user use. It is therefore essential to think about the size of the buttons and their position on a joystick to make them easily accessible. It is also important to consider the sensitiveness of the joystick which can be adjusted to a range of levels depending on the preferences of each user.

Comfort

A joystick-controlled power chair (by clicavisos.com.ar) offers many benefits that aren't accessible with manual chairs. They minimize fatigue triggered by operational issues and allow for longer travel times over manual wheelchairs. Additionally, they can be used in areas with fewer spaces and more challenging terrain than a manual one, for example, outdoor slopes or uneven surfaces. This additional freedom allows users to experience the freedom of movement and feeling of independence.

There are many different power wheelchairs available each with its distinct characteristics. The amount of bells and whistles available on a specific model will depend on the user's needs and wants. The most commonly used features are:

The control options on an electric lightweight wheelchair wheelchair equipped with the joystick is a possibility to meet the needs of each individual. This includes the type of knob, ball or handle and how it is mounted. Some joysticks are positioned on the opposite side of the dominant armrest while others are situated either on the back or front of the seat for easy access by an attendant controlled electric power wheelchair. Some joysticks can be positioned on the side for those who have limited shoulder range or a weakness in their muscles.

Other features are more personal in nature such as the size and design of the joystick display screen. Some models are backlit or have a color that is easier to read for those with poor vision. Other models have auxiliary modes that offer audio or visual clues to aid in navigation. Other models may include odometers, clocks, and indicators for battery charge.

Another important aspect of the joystick is how it can be controlled in narrow turning radius. The best-performing models will have a narrow turning radius, which allows for easier navigation of obstacles in narrow spaces, like hallways. The tight turning radius also allows for easier maneuvering through public areas and 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 have been created with safety as a priority. They are equipped with reliable brake systems that can slow the speed as quickly as the consumer presses the joystick control. They also have anti-tip wheels in the rear that keep the chair from slipping backward.

The most popular type of joystick is a proportional control, which is similar to accelerator pedals and video game controllers in that the more the joystick is moved away from center, the speed at which the wheelchair moves. These types of joysticks require intact proprioception as well as finger dexterity to work effectively. Standard joysticks are mounted on the armrest. However, there are a variety of special controls that put the control on the side or middle of the seat.

Some consumers may not have enough muscle strength to withstand the force of a joystick, even with the help of special rigging. This is the case for those who suffer from spasticity, which can cause muscles to stiffen or waste away (atrophy). In these instances it might be beneficial to utilize a head-control unit that converts the movements of the consumer's body into the appropriate commands for the wheelchair.

The size and position of the joystick's buttons is another thing to be considered. If the buttons are far in the front or difficult to reach, they may interfere with the seating position of the user and create a strain on the hands. On the other side when the joystick is placed too far backward it could be difficult to turn the wheels or move the chair into tight spaces.

The seatbelt should be fastened on an electric wheelchair. Seatbelts should always be fastened when using an electric wheelchair. The most powerful wheelchairs can travel as fast as 8mph. Batteries should be charged frequently and, ideally, every night. This will ensure longer life and keep their effectiveness. You should also keep your chair checked regularly to ensure that all parts are operating effectively.

Accessories

Joysticks are a key component of power wheelchairs and can be enhanced with a variety of accessories. These can range from simple switches, to more advanced interfaces that connect to communication devices, and even external environmental control units. A higher-end power wheelchair usually comes with several controller components that can be used and configured to meet the needs of a specific client. A non-expandable control can only accept a proportional stick as an input device however, an expandable control will also accept sip and puff control, special switches, as well head array systems. Some of the advanced controllers are able to operate up to two power seating actuators, which can alter the seat's angle and position of the seat.

The most basic type of joystick commonly prescribed in the clinic is an inverse control, often referred to as a movement sensing joystick. This type of joystick responds force by increasing output (i.e. wheelchair speed) as the stick is moved away from the center. This requires a good amount of proprioception intact and dexterity for efficient use.

Although the technology used today can be used to compensate for small amplitude movements in EPW driving, it is still unable to detect and adjust to more severe, unintentional movements, like those caused by larger involuntary or amplitude tremors that are not accompanied by conscious intent like athetosis.5 As long as we don't develop and implement new technologies that can reliably detect and adjust to these types of unintentional movements, many people suffering from conditions such as athetosis, MS, ALS or spinal cord injury will not be able to safely use an electric power chair.

Most wheelchairs have a range of parameters that can be programmed or customized typically with the help of a medical professional. These parameters include changing the torque produced by the motor, altering the speed that the chair moves and setting the dead zone that is the area within which the EPW will not generate an output. Some controllers also be able to store backup programs, which is useful for a clinician to keep in the event of an emergency or for a client with fluctuating symptoms.
