Power wheelchairs with joysticks can significantly increase accessibility and independence. However, standardized joysticks can lack accommodation of individualized features of hand dysfunction.

This study assessed the efficacy and satisfaction of custom-designed power wheelchair Joysticks manufactured with 3D printing. 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 a power wheelchair comprises two essential components that are the joystick and electronics (also known as the controller). The standard joysticks are placed on the left or the right side of the wheelchair, whereas more sophisticated rehab chairs come with swing-away mounts which allow the joystick to slide into the middle of the seat.

The way that a joystick is mounted and used will play an important role in determining whether it will be effective for a specific customer. For instance when a person suffers from severe tremors, it is essential to ensure that the joystick is designed such a manner that these movements do not trigger accidental activations of the chair. The standard EPW joysticks typically use proportional input devices that respond to the amount of deflection on the gimbal in order to regulate the movement of the chair (similar to an accelerator pedal or video game controller).

There are several different control options for power wheelchairs that require minimal force to activate. Switch controls, sip-and puff controls as well as head arrays and chin controls are all accessible. While some of these controls require an additional interface to connect them to the wheelchair, many are compatible with the latest generation of joysticks that have integrated Bluetooth into their handles.

Some standard wheelchair joysticks even have a screen to show the status of the system and provide feedback to the user. This is especially useful for people with visual or cognitive impairments. Other joysticks with advanced technology have the capability of controlling many different devices like environmental controls, and even a tablet or TV.

Whatever technology is employed the joystick will be as effective if the user finds it comfortable to use. It is therefore crucial to consider the dimensions of the buttons and their position on the joystick to make them easy to access. Additionally, it is important to think about the sensitivity of the joystick, which can be adjusted to a variety of levels based on the requirements of each user.

Comfort

A joystick-controlled chair has many advantages that a manual chair does not offer. They help reduce fatigue due to operational factors and can travel longer distances than manual chairs. Additionally, they can be used in locations with fewer spaces and more difficult terrain than a manual one, such as outdoor slopes or uneven surfaces. With this added independence users will experience a freedom of movement that brings new life to their lives and reminds them of how it feels to be able to move around independently.

There are many different power wheelchairs on the market each with its distinct characteristics. The number of bells and whistles on the specific model will depend on the needs of the user and desires. Some of the most common features are:

Controls on an electric wheelchair with joysticks can be adapted to fit individual needs. This includes the type of knob or handle, as well as the ball or the manner in which it is mounted. Some joysticks are positioned on the end of the armrest that is dominant, while others are located either on the back or front of the seat to allow easy access by an attendant. Certain joysticks can be placed on the side for people with limited shoulder range or a weakness in their muscles.

Other features are more personal in nature such as the size and style of the joystick display screen. Some are backlit or in colors that are easier to read for people who have low vision. Other models have additional modes that provide audio or visual clues to help navigate. They can also offer clocks, odometers, as well as indicators of battery charge.

Another crucial aspect of the joystick is how it can be operated within 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 in public places and in stores. This tight turning circle is particularly beneficial for those with mobility issues, like cerebral palsy, or other mobility issues such as multiple sclerosis ALS and Huntington's disease, brainstem or spinal cord injury stroke.

Safety

Power wheelchairs are designed with safety in mind. They have reliable brake systems that can limit the speed rapidly when the consumer presses the joystick control. 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 accelerator pedals for cars, in that it accelerates the wheelchair the further the joystick is away from the center. These kinds of joysticks require proprioception as well as finger dexterity to operate efficiently. Standard joysticks are mounted on the armrest. However there are several of special controls that put the control on the middle or side of the seat.

Some people may not have enough muscle strength to deflect a joystick handle, even with the aid of special rigging. This is the case for those who suffer from spasticity, which can cause muscles to stiffen or deteriorate (atrophy). In these instances it might be beneficial to use a head-control device that converts the movements of the consumer's body into the commands for the wheelchair.

Another factor to consider is the size and position of the joystick's buttons. If the buttons are too far to the left or difficult to reach, it could affect the user's position and result in stress on their hands. On the other hand, if the joystick is located too far backwards, it can be difficult to turn the wheels or move the chair into tight spaces.

Finally, an electric wheelchair is best used with the seatbelt fastened. The most powerful wheelchairs can travel at speeds up to 8 mph and a seatbelt that is not fastened could result in grave injuries or even death. Batteries must be charged regularly and preferably every night. This will ensure that they have a longer lifespan and maintain their efficiency. It's also recommended to perform regular maintenance for your chair to make sure all parts are working properly.

Accessories

The joystick is an essential element of any power wheelchair and there are many accessories that can be added to improve its capabilities. These range from simple switches up to more complex interfaces that connect to communication devices as well as external environmental control units. A higher-end power wheelchair usually comes with several controller components that can be utilized and adapted to meet the needs of a particular user. A non-expandable control will only accept the proportional stick as an input device, while an expandable one can also take sip and puff control, specialty switches, and head array systems. Some advanced controllers can also use up to two power seating actuators that are able to adjust the position and tilt of the seat.

The most basic type of joystick that is commonly used in the clinic is a proportional control, also referred to as a movement sensing joystick. This type of joystick like automobile accelerator pedals 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 significant amount of proprioception that is intact and dexterity to be able to use the wheelchair.

The technology used today can compensate for minor variations in amplitude when EPW driving. However, electric Wheelchair with joystick it's not able to recognize and adjust for more severe unintentional motions, such as those caused by tremors with greater amplitude, or involuntary movements that aren't caused by conscious intent, such as athetosis.

Most wheelchairs have a range of different parameters that can be programmed and customised, usually with the help of a clinician. These parameters include changing the torque generated by the motor, altering the speed at which the chair moves and setting the dead zone that is the area 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 or if a patient's symptoms alter.
