Electric Wheelchair With Joystick
Power wheelchairs with joysticks can significantly improve independence and ease of use. However, standardized joysticks can be incompatible with the individualized features of hand dysfunction.
This study evaluated the effectiveness and satisfaction of custom-designed power wheelchair Joysticks made with 3D printing. Modified power-mobility indoor driving assessment (PIDA), National Aeronautics and Space Administration task load index, and the psychosocial impact of assistive devices scale were used for evaluation.
Control
The control system of a power chair comprises two key components that are the joystick and electronics (also called the controller). Standard joysticks are mounted on either the left or right side of the wheelchair, whereas more advanced rehab chairs feature swing-away mounts that permit the joystick to move to the middle of the seat.
The way that a joystick is placed and operated is a significant factor in determining whether it can be a success for a specific customer. For example, if an individual suffers from severe tremors, it is essential to ensure that the joystick is constructed in such a manner that these movements will not trigger accidental activations of the chair. Standard EPW joysticks utilize proportional input devices that react to the deflection amount of the gimbal to control the chair's motion (similar to a video game controller or a car accelerator pedal).
There are a myriad of alternative control options for power wheelchairs that require very little force to activate. These include switch controls sip and puff control as well as head array systems and the chin control. Certain of these controls require an additional interface to connect to the wheelchair. However, most of them are compatible with new joysticks which incorporate Bluetooth into the handles.
Some of the standard wheelchair joysticks have a screen to display the status of the system and provide feedback to the user. This is especially useful for those with visual or cognitive impairments. Certain advanced joysticks are able to control a wide range of accessories, including televisions, environmental controls and tablet.
Whatever technology is used, a joystick will only be as effective as the user finds it easy to use. For this reason, it is essential to consider the size and location of the buttons on a joystick to ensure that they are easy to access. It is also crucial to take into consideration the sensitivity of the joystick, which can be set to a range of levels depending on the specific needs of the user.
Comfort
A joystick-controlled power chair has many advantages not available with a manual chair. They minimize fatigue triggered by operational issues and allow for longer travel distances over manual wheelchairs. Additionally, they can be used in areas with less space and more challenging terrain than a manual wheelchair, like outdoor slopes or uneven surfaces. This added independence gives users the freedom of movement and feeling of independence.
A variety of different powered wheelchairs are available with a wide range of options. The amount of bells and whistles included on the particular model will be contingent on the needs of the user and wants. The most commonly used features include:
Controls on an electric wheelchair with joysticks can be adapted to fit individual needs. This includes the type and location of the ball, knob, or handle. Joysticks are usually located on the armrest of the driver's chair and others are positioned in the front or back of the seat to make it easier for an attendant to reach. Some joysticks can be mounted on the side of the seat for those who have limited shoulder range or muscular weakness.
Other features are more personal to you like the size and design of the joystick display screen. Some models are backlit or have the color of the screen, which makes it easier for those with poor vision to read. Certain models come with additional modes that provide audio or visual navigation indicators. Other models could include odometers, clocks, and battery charge indicators.
Another important aspect of the joystick is how well it can be operated within narrow turning radius. The most efficient models will have a narrow turning radius that allows for easier navigation of obstacles in narrow areas, such as hallways. The tight turning radius also allows for easier maneuvering through public areas and 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 made with safety in mind as the top priority. They have reliable brake systems that can reduce the speed as quickly as the consumer presses the joystick control. The chairs are also equipped with anti-tip rear wheels to prevent the chair from tipping forward.
The most common type of joystick is a proportional controller, which is similar to automobile accelerator pedals and video game controllers in that the more the joystick is moved away from the center the speed at which the wheelchair moves. These types of joysticks require intact proprioception and finger dexterity in order to operate effectively. Joysticks that are standard are mounted on the armrest. However there are many specialty controls that mount the controls on the side or middle of the seat.
Even with special rigging, certain people may not be able to turn a handle. This is the case for some people who suffer from spasticity, which can cause muscles to stiffen or deteriorate here (atrophy). In these instances it is possible to use a head control device that transforms the movement of the user's head into a instructions for the wheelchair may be a better option.
Another thing to take into consideration is the size and placement of buttons on the joystick. If the buttons are too far forward or hard to reach, they may interfere with the position of the user, and cause stress on the hands. On the other hand, if the joystick is too far backward it could be difficult to turn the wheels or maneuver the chair through tight spaces.
The seatbelt should be secured on an electric wheelchair. The most powerful wheelchairs can reach speeds up to 8 mph and a seatbelt that is not fastened could result in serious injuries or death. It is also important to ensure that batteries are charged frequently, and every night, if it is possible. This will help them to last longer and ensure their efficiency. It's also an excellent idea to schedule regular maintenance on your chair to ensure the components are in good working order.
Accessories
The joystick is a major element of any power wheelchair, and there are many accessories that can be added to boost its functionality. They range from simple switches to more advanced interfaces that can connect to communication devices or external environmental control units. A high-end power wheelchair usually comes with various controller components that can be used and adapted to meet the requirements of a specific client. For example, a non-expandable controller will typically only accept a proportional joystick as an input device while an expandable controller may allow sip and puff controls, specialty switches and head array systems. Some of the more advanced controllers can even operate up to two power seating actuators that can be used to adjust the seat's position and tilt of the seat.
The most basic type of joystick commonly prescribed in the clinic is a proportional control, sometimes referred to as a movement sensing joystick. This type of joystick responds the force by boosting output (i.e. The speed of the wheelchair increases as the stick is moved away from the center. This requires a good amount of proprioception intact and dexterity for effective use.
Although the technology used today is able to compensate for minor variations in amplitude during EPW driving, it is still unable to detect and adjust to many more severe unintentional movements, like those caused by higher magnitude tremors or other involuntary movements that are not associated with conscious intention, such as athetosis.5 Until we can develop and implement new technology that can reliably detect and adapt to these kinds of unintentional movements, a lot of sufferers with diseases such as athetosis, MS, ALS or spinal cord injury will not be able to safely operate an electric power chair.
Most wheelchairs can be customised and programmed by a clinician. These parameters could include altering the torque produced by the motor, altering the speed of the chair and setting the dead zone that is the area within which the EPW will not generate an output. Some controllers also have the ability to store backup programs, which is useful for a clinician to have on hand in the event in the event of an emergency or a client with fluctuating symptoms.
