Electric Wheelchair With Joystick

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

This study evaluated the effectiveness and satisfaction of customized 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 to evaluate.

Control

The control system of the power chair comprises two important components: the joystick and the electronic. Joysticks that are standard mount to the left or right sides of the chair, whereas more complex rehab chairs may feature swing-away mounts that allow the joystick to be positioned in the centre of the seat.

The way a joystick is installed and used is a significant factor in determining whether it will be effective for a specific user. If a user is prone to tremors, it is essential to design the joystick so that the movements do not activate the chair accidentally. The standard EPW joysticks typically use proportional input devices, which respond to the amount of deflection of the gimbal to control the movement of the chair (similar to an automobile accelerator pedal or video game controller).

There are a variety of alternative control options for power wheelchairs that require a minimum of force to activate. Switch controls, sip-and-puff controls as well as head arrays and chin controls are all available. While some of these special controls require a separate interface to connect them to the wheelchair, most are compatible with the new generation of joysticks, which have integrated Bluetooth into their handles.

A few standard wheelchair joysticks come with a screen to show the status of the system, and give feedback to users. This is particularly useful for people who are cognitively or visually impaired. Certain advanced joysticks are able to control a wide range of accessories such as televisions, environmental controls and tablet.

Whatever technology is used, a joystick can only be as effective as the user feels comfortable to use. It is therefore crucial to consider the dimensions of the buttons and their position on the joystick to make them easily accessible. Also, it is essential to think about the sensitiveness of the joystick which can be adjusted to a range of levels based on the requirements of each client.

Comfort

A joystick-controlled chair has many advantages that manual chairs do not offer. They reduce fatigue due to operational issues and can travel for longer distances than manual-operated chairs. They can also be used in areas with less space and more difficult terrain than a manual one, for example, outdoor slopes or uneven surfaces. With this added independence users will experience an ease of movement that brings new life to their lives and reminds them of how great it is to be independent again.

A variety of different power wheelchairs are available with an array of options. The amount of bells and whistles available on a specific model will depend on the requirements of the user and their desires. Some of the most commonly used features are:

Controls on an electric wheelchair that have a joysticks can be adapted to meet the needs of each individual.  My Mobility Scooters  includes the type of knob or handle, or ball, and the way it is mounted. Joysticks are usually located on the armrest of the driver's seat and others are positioned on the front or rear of the seat to make it easier for an attendant to reach. They may also be mounted on the sides of the seat for those with limited shoulder range or muscle weakness.

Other features are more personalized, such as the style and size of the joystick's screen. Some models are backlit or have the color of a display that is more accessible for those with low vision. Some models also have auxiliary modes that offer visual or audio cues for navigation. Other models may include odometers, clocks and indicators of battery charge.

Another crucial aspect of the joystick is how well it can be operated within narrow turning radius. The most efficient models will have a tight turning radius that allows for easier navigation of obstacles in narrow spaces, such as hallways. This tight turning radius makes it easier to navigate through public spaces and stores. This radius of tight turning is particularly useful for people with mobility issues such as cerebral palsy, MS, ALS, Huntington's disease, spinal cord injury or brainstem stroke.

Safety

Power wheelchairs have been made with safety in mind as a priority. They have reliable brake systems that can reduce the speed as quickly as the consumer presses the joystick control. They also have anti-tip wheels in the rear that prevent the chair from tipping backward.

The most common type of joystick is a proportional controller, which is similar to car accelerator pedals as well as video game controllers in that the more the joystick is moved away from its center, the more quickly the wheelchair moves. These types of joysticks need proprioception as well as finger dexterity to function effectively. A standard joystick is usually placed on the armrest however, a variety specific controls are available that mount the control in the middle or at the sides of the seat.

Even with specialized rigging, some people might not be able deflect the handle. This is the case with some people who suffer from spasticity, which can cause muscles to become stiff or waste away (atrophy). In these instances, a head control unit that converts the movement of a user's head into a command for the wheelchair might be a better option.

The size and position of the joystick's buttons is another thing to be considered. If the buttons are too far to the left or difficult to reach, it can alter the user's sitting position and result in stress on their hands. If the joystick is placed too far back, it may be difficult to maneuver the chair or turn the wheels.

Additionally, an electric chair should always be operated with a seatbelt that is fastened. The most powerful wheelchairs can reach speeds of up to 8 miles per hour and a seatbelt that isn't fastened can result in serious injuries or death. It is also essential to charge batteries frequently, and every night, if it is possible. This will ensure a longer lifespan and maintain their efficiency. You should also have your chair regularly maintained to ensure that all parts are operating correctly.

Accessories

Joysticks are a key component of power wheelchairs and can be upgraded by a variety of accessories. These range from simple switches to more sophisticated interfaces that 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 meet the needs of different clients. A non-expandable control will only accept the proportional stick as an input device while an expandable model can also take sip and puff control, special switches, as well as head array systems. Certain advanced controllers can operate up to two power seating actuators, that can alter the position and angle of the seat.

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

While the technology that is in use today is able to compensate for minor magnitude movements that occur during EPW driving, it is still 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 intention, such as athetosis.5 As long as we don't develop and implement new technologies that can reliably detect and adapt to these kinds 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 number of different parameters that can be programmed or customized usually with the assistance of a medical professional. These parameters include changing the torque generated by the motor, altering 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 have the ability to save backup programs, which are handy for a healthcare professional to have in the event of an emergency or for patients with varying symptoms.
