Joysticks on power wheelchairs can significantly improve accessibility and independence. However, standard joysticks may lack accommodation of individualized features of hand dysfunction.

This study evaluated the efficacy and satisfaction of custom-designed power wheelchair joysticks fabricated with 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 used to evaluate.

Control

The control system of a power chair has two important components: the joystick and the electronic. The standard joysticks are placed on the left or the right side of the wheelchair, while more sophisticated rehab chairs come with swing-away mounts that permit the joystick to slide to the middle of the seat.

The manner in which a joystick is mounted and used is essential to its performance for a client. For example in the case of someone who has a significant amount of tremors, then it is crucial to ensure the joystick is designed such a way that these movements will not trigger accidental activations of the chair. Standard EPW joysticks use proportional input devices that respond to the deflection of the gimbal to control the chair’s movements (similar to an electronic game controller or a car accelerator pedal).

There are a variety of alternatives to control options for power wheelchairs that require very little force to activate. These include switch controls sip and puff control head array systems, and the chin control. Some of these controls require an additional interface to connect to the wheelchair. However, most of them are compatible with new joysticks that incorporate Bluetooth into the handles.

Some standard wheelchair joysticks even come with a screen to display the status of the system and provide feedback to the user, which is especially useful for those with visual or cognitive impairments. Certain advanced joysticks are able to control a wide range of accessories that include environmental controls, a TV and tablet.

No matter what technology is used the joystick is as useful as it is comfortable for the user to operate. It is therefore crucial to think about the size of the buttons and their placement on a joystick to make them easy to access. It is also crucial to consider the joystick’s sensitivity that can be set to a variety of levels according to the needs of each user.

Comfort

A joystick-controlled powerchair has many advantages not offered by manual chairs. They reduce fatigue caused by operational issues and permit longer travel distances than manual-operated counterparts. They can also be used in areas that have less space or more challenging terrain, such as outdoor slopes and uneven surfaces. With this added mobility, users can experience the freedom of movement that gives new life to their lives and reminds them of how it feels to be able to move around independently.

There are numerous different power wheelchairs on the market, each with their distinct characteristics. The number of bells and whistles on the particular model will be contingent on the user’s needs and desires. Some of the most popular features are:

Controls on an light electric wheelchairs wheelchair that have a joysticks can be modified to meet your individual requirements. This includes the type and location of the knob, ball, or handle. Some joysticks are positioned on the top of the dominant armrest, while others are located in the front or back of the seat for easy access by the attendant. They can also be positioned on the sides of the seat for people with limited shoulder range or muscles that are weak.

Other features can be more customized like the design and size of the joystick’s screen. Some models are backlit, or have the color of the screen, which makes it easier for people with low-vision to read. Certain models come with auxiliary modes which provide audio or visual navigation indicators. Other models may include odometers, clocks and battery charge indicators.

The ability of a joystick to maneuver in a small turning radius is also important. The best models will have a narrow turning radius, which makes it easier to navigate obstacles in tight spaces, like hallways. The tight turning radius also allows for easier maneuvering in public spaces and in stores. This radius of tight turning is particularly 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 are designed with safety in mind. They have robust brake systems that can limit the speed quickly when the consumer presses the joystick control. They also have anti-tip wheels at the rear to stop the chair from sliding backward.

The most common type of joystick is a proportional controller, which is similar to accelerator pedals as well as video game controllers in that the more the joystick moves away from its center, the faster the wheelchair moves. These joysticks require finger dexterity and good proprioception to operate. A standard joystick is typically mounted on the armrest, however, a variety of specialty controls are available that mount the control in the middle or at the sides of the seat.

Some people may not have enough strength to deflect a joystick handle, even with special rigging. This may be the case for some people who have spasticity, which can cause muscles to become stiff or deteriorate (atrophy). In these cases, a head control unit that converts the movement of the head of the user into the needed instruction for the wheelchair could be a better choice.

The size and position of the joystick’s buttons is another aspect to consider. If the buttons are too far to the left or difficult to reach, it could affect the user’s seating position and put strain on their hands. On the other side, if the joystick is too far backward it could be difficult to turn the wheels or maneuver the chair through tight spaces.

Lastly, an electric wheelchair price wheelchair should always be used with the seatbelt fastened. The most powerful wheelchairs can reach speeds up to 8 mph and a seatbelt that isn’t fastened can lead to serious injuries or even death. Batteries should be charged frequently and, ideally, every night. This will ensure that they have an extended life span and will maintain their efficiency. It is also recommended to have your chair maintained regularly to ensure that all components are working correctly.

Accessories

Joysticks are a key component of power wheelchairs. They can be upgraded by adding a variety. They can range from basic switches up to more complex interfaces that connect to communication devices, and even external environmental control units. Power wheelchairs with higher end features will typically have a variety of controller components that are able to meet the requirements of different users. For example an unexpandable controller will typically accept a proportional joystick as an input device while an expandable controller may allow puff and sip controls, specialty switches, and head array systems. Some advanced controllers can also use up to two power seating actuators, which are able to adjust the seat’s position and tilt of the seat.

The most basic type of joystick that is commonly used in the clinic is a proportional control, sometimes called a movement sensing joystick. This kind of joystick responds to the force by increasing output (i.e. The speed of the wheelchair increases as the stick moves away from the center. This requires a good deal of dexterity as well as a strong proprioception to be able to use it effectively.

While the technology that is in use today is able to compensate for minor variations in amplitude during EPW driving however, it is unable to detect and adjust to more severe and unintentional movements, like those caused by greater amplitude tremors or involuntary movements that are not accompanied by conscious intent like athetosis.5 As long as we don’t create and implement new technologies that are able to reliably detect and adapt to these kinds of unintentional movements, a lot of people suffering from conditions such as athetosis, MS, ALS or spinal cord injuries will not be able to safely operate an electric bariatric wheelchair power chair.

Most wheelchairs can be programmed and customized with the help from an expert. These parameters can include changing the torque generated by the motor, changing the speed at which 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 store backup programs which are handy for a healthcare professional to have in case in the event of an emergency or a client with fluctuating symptoms.
