Joysticks on power wheelchairs can significantly increase independence and ease of use. Standardized joysticks may not be able to accommodate the unique characteristics of hand impairment.

This study examined the efficacy and satisfaction of customized 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 psychosocial impact of assistive devices scale were employed for evaluation.

Control

The control system of a power wheelchair comprises two essential components which are the joystick as well as the electronics (also known as the controller). Standard joysticks often mount to either the left or right sides of the chair. However, more sophisticated rehab chairs might feature swing-away mounts that allow the joystick to be moved to the middle of the seat.

The manner in which a joystick can be mounted and used will play a crucial role in determining whether it will be successful for a particular customer. If a user has a lot of tremors it is essential to design the joystick so that the movements don't cause the chair to move accidentally. The standard EPW joysticks typically use proportional input devices, which respond to the amount of deflection on the gimbal in order to determine the direction of the chair (similar to an automobile accelerator pedal or video game controller).

However, there are now a number of different alternative control options for power wheelchairs that require minimal force to activate. Switch controls, sip-and puff controls head arrays, sip-and-puff controls, and chin controls are all available. While some of these specialty controls require a separate interface to connect them to the wheelchair, a lot are compatible with the latest 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. This can be particularly useful for people who have visual or cognitive impairments. Other advanced joysticks have the capability of controlling various accessories, including environmental controls and even a tablet or TV.

Whatever the technology the joystick is useful if it's easy for the user to use. It is therefore crucial to consider the dimensions of the buttons and their placement on the 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 client.

Comfort

A joystick-controlled chair has many advantages that manual chairs do not have. They reduce fatigue caused by operational issues and allow for longer travel times than manual-operated counterparts. Additionally, they can be used in areas with fewer spaces and more difficult terrain than a manual one, like uneven surfaces or slopes in the outdoors. With this added independence users can enjoy the freedom of movement that gives new life to their lives and reminds users of the feeling to be able to move around independently.

There are many different power wheelchairs available each with its distinct features. The quantity of bells and whistles that the particular model comes with will depend on what the user wants and needs. Some of the most commonly used features include:

Controls on an cheap electric wheelchairs wheelchair that have a joysticks can be modified to meet your individual requirements. This includes the type and location of the ball, knob, or handle. Some joysticks are located at the end of the armrests of the driver's seat While others are set on the rear or front of the seat to make it easier for attendants to reach. Certain joysticks can be placed on the side for those with limited shoulder range or muscular weakness.

Other features are more personalized, such as the style and size of the joystick's display. Some models are backlit or have colors that are more accessible for those who have low vision. Some models also have additional modes that provide audio or visual cues to help navigate. Other models can include 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 small turning radius, making it easier to maneuver around obstacles and narrow spaces like hallways. This radius of tight turning allows for easier navigation in public places and in stores. This tight turning radius is particularly useful for people who have mobility issues, such as cerebral palsy, MS, 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 which can slow down speed quickly when the consumer depresses the joystick control lever. The chairs are also equipped with anti-tip rear wheels to prevent the chair from tipping forward.

The most popular type of joystick is a proportional control which is similar to car accelerator pedals and video game controllers in that the more the joystick is moved away from the center the faster the wheelchair moves. Joysticks that are proportional require a strong hand and a healthy sense of proprioception. A standard joystick is typically placed on the armrest, but a variety of different special controls are available to place the controls in the middle or at the sides of the seat.

Some consumers may not have enough muscle strength to deflect a joystick's handle even with special rigging. Some people with spasticity may be a bit troubled because their muscles may become stiff or weak. In these instances, a head control unit that converts the movement of the user's head into a instruction for the wheelchair could be a better choice.

Another thing to take into consideration is the size and location of buttons on the joystick. If the buttons are too far forward or are difficult to reach, it may affect the user's seating position and cause stress on their hands. On the other side when the joystick is too far backward it could be difficult to turn the wheels or maneuver the chair into tight spaces.

The seatbelt must be fastened on an electric wheelchair. The most powerful wheelchairs can travel at speeds of up to 8 mph and a seatbelt that isn't fastened could result in serious injuries or death. Batteries must be charged regularly and, ideally, every night. This will allow them to last longer and ensure their efficiency. It's also an excellent idea to schedule regular maintenance for your chair to make sure all parts are working properly.

Accessories

Joysticks are an essential element of power wheelchairs and can be improved by a variety of accessories. These range from basic switches to more sophisticated interfaces that can connect to communication devices or external environmental control units. Higher-end power wheelchairs will often include a variety of controller components that are able to meet the requirements of various clients. A non-expandable control will only accept a proportional stick as an input device however, an expandable control will also accept sip and puff controls and specialty switches, and head array systems. Some advanced controllers can also use up to two power seating actuators that are able to adjust the seat's position and tilt of the seat.

The most common type of joystick prescribed in clinics is a proportional joystick, also known as a motion-sensing joystick. This type of joystick like accelerator pedals for 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 when the stick is moved away from the center. This requires a significant amount of proprioception intact and dexterity for efficient use.

While the technology that is in use today can compensate for small magnitude movements that occur during EPW driving however, it is unable to recognize and adjust to more severe, unintentional movements, like those caused by higher amplitude tremors or involuntary movements that aren't associated with conscious intent like athetosis.5 As long as we don't develop and implement new technology that are able to reliably detect and adjust to these types of unintentional movements, a lot of people with conditions like athetosis, MS, ALS or spinal cord injury will not be able safely to use an electric power chair.

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