Joysticks for power wheelchairs can enhance their use and independence. Standard joysticks are not able to be able to accommodate the unique characteristics of hand impairment.

This study assessed the effectiveness and satisfaction of custom-designed power wheelchair joysticks made using 3D printing technology. Modified power-mobility power chair 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 for a power chair has two essential components: the joystick and the electronic. Joysticks that are standard mount on the left or right sides of the chair, while more complex rehab chairs may include swing-away mounts that permit the joystick to be moved into 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 essential to ensure that the joystick is designed such a way that the movements will not trigger accidental activations of the chair. The standard EPW joysticks typically use proportional input devices, which respond to the amount of deflection of the gimbal to regulate the movement of the chair (similar to an accelerator pedal or video game controller).

There are numerous alternative control options for power wheelchairs that require very minimal force to activate. Controls for switches, sip-and-puff as well as head arrays and chin controls are all accessible. Certain of these controls require an additional interface to connect to the wheelchair. However, a lot of them can be used with new joysticks which incorporate Bluetooth into the handles.

A few standard wheelchair joysticks come with screens that display the condition of the system and to provide feedback to the users. This can be especially useful for those who are visually or cognitively impaired. Some advanced joysticks can control a wide range of accessories such as televisions, environmental controls and tablet.

Whatever the technology the joystick is as effective if it is comfortable for the user to use. It is therefore important to think about the size of the buttons and their position on a joystick to make them accessible. It is also essential to think about the sensitivity of the joystick, which can be set to a variety of levels based on the individual needs of the user.

Comfort

A joystick-controlled wheelchair has many advantages that a manual chair does not offer. They limit fatigue caused by operational issues and allow for longer travel times than manual-operated counterparts. They can be utilized in areas with less space or more difficult terrain, such as outdoor slopes and uneven surfaces. This additional independence allows users to experience the freedom of movement as well as a feeling of independence.

A variety of power wheelchairs are offered with an array of options. The amount of bells and whistles that a particular model features will depend on what the user prefers and needs. Some of the most popular features include:

Customization of controls on an electric powered wheelchair chair with the joystick is a possibility to meet the needs of each individual. This includes the type and location of the knob, ball or handle. Some joysticks are placed at the end of the dominant armrest, while others are placed in the front or back of the seat to facilitate access by a person who is. Certain joysticks can be placed on the side of the seat for those with limited shoulder range or muscular weakness.

Other features are more personal in nature like the size and shape of the joystick display screen. Some models are backlit or have colors that make it easier for people who have low vision to read. Other models provide auxiliary modes that offer audio or visual cues to aid in navigation. Other models may include odometers, clocks and battery charge indicators.

A joystick's ability to maneuver within a narrow turning radius is also essential. The best models will have a narrow turning radius, which allows for easier navigation of obstacles in narrow spaces, like hallways. This radius of tight turning makes it easier to navigate through public spaces and stores. This narrow turning radius is particularly beneficial for those who suffer from mobility issues like cerebral palsy, multiple sclerosis ALS Huntington's disease spinal cord injury or brainstem stroke.

Safety

Power wheelchairs were designed with safety as a top priority. They have reliable brake systems that can limit the speed quickly when the user presses the joystick control. The chairs are also equipped with anti-tip rear wheels that prevent the chair from tipping forward.

The most common joystick type is one that is proportional. It is similar to video game controllers and accelerator pedals for cars in that it moves the wheelchair faster the further the joystick is from the center. Joysticks that are proportional require a strong hand and a healthy sense of proprioception. The standard joysticks are positioned on the armrest. However there are many specialty controls that mount the controls on the side or middle of the seat.

Even with specialized rigging some consumers may not be able to deflect a handle. This could be the case for those who have spasticity, which 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 a user's head into a instruction for the wheelchair could be a better choice.

Another factor to consider is the size and location of the joystick's buttons. If the buttons are far in the front or difficult to reach, they may hinder the seating position of the user and cause a strain on the hands. If the joystick is too far back, it could be difficult to move the chair or turn the wheels.

Finally, an compact electric wheelchair wheelchair should always be used with a seatbelt secured. Seatbelts should always be fastened when using an electric wheelchair. The most powerful wheelchairs can travel up to 8mph. Batteries must be charged regularly and preferably every night. This will ensure a longer lifespan and maintain their efficiency. You should also have your chair regularly maintained to ensure that all components are functioning effectively.

Accessories

The joystick is a major element of any power wheelchair, and there are many accessories that may be added to improve its capabilities. These range from basic switches to more advanced interfaces that can connect to communication devices, or external environmental control units. Power wheelchairs with higher end features will typically have a variety of controller components that can satisfy the requirements of different users. A non-expandable control can only accept a proportional stick as an input device, while an expandable model will also accept sip and puff controls and special switches, as well head array systems. Certain advanced controllers are able to operate up to two lightweight power chairs seating actuators, which can alter the seat's position and angle of the seat.

The most basic type of joystick that is commonly used in the clinic is an inverse control, often called a motion sensing joystick. This kind of joystick, like accelerator pedals for cars and video game controllers, responds to the force exerted on the stick by increasing its output (i.e. wheelchair speed) as the stick is pushed away from center. This requires a good deal of dexterity and a healthy sense of proprioception for efficient use.

The technology that is used today is able to compensate for a small electric wheel chair movements in amplitude during EPW driving. However, it's not able to recognize and adjust for more serious unintentional movements, such as those caused larger amplitude tremors, or involuntary movements that are not related to conscious intent like athetosis.

Most wheelchairs have a range of different parameters that can be programmed and customised typically with the help of a physician. These parameters can include changing the torque produced by the motor, changing the speed that the chair moves and setting the dead zone that is the area within which the EPW will not generate an output. Certain controllers will also be able to save backup programs, which is useful for a healthcare professional to keep in the event in the event of an emergency or clients with varying symptoms.
