Electric Wheelchair With Joystick
Joysticks on power wheelchairs can significantly increase accessibility and independence. Standard joysticks are not able to be able to accommodate the unique characteristics of hand dysfunction.
This study examined the efficacy and satisfaction of customizing power wheelchair joysticks that were made using 3D printing technology. The evaluation was conducted using the modified power-mobility inside driving assessment (PIDA), National Aeronautics and Space Administration Task Load Index, and Psychosocial Impact of Assistive Devices Scale.
Control
The control system for the power chair comprises two important components: the joystick and the electronic. Standard joysticks are mounted on the left or the right side of the chair, while more sophisticated rehab chairs come with swing-away mounts that allow the joystick to slide into the middle of the seat.
The way in which a joystick is mounted and used is vital to its success for a user. If a person is prone to tremors, it is essential to design the joystick such that the movements do not cause the chair to move accidentally. The standard EPW joysticks are typically proportional input devices that respond to the level of deflection on the gimbal to control the movement of the chair (similar to an automobile accelerator pedal or video game controller).
There are many alternatives to controlling power wheelchairs, that require very little force to activate. These include switches, sip and puff controls, head array systems and chin controls. Certain of these controls require an additional interface to connect to the wheelchair. However, many of them work with new joysticks that incorporate Bluetooth into the handles.
Some standard wheelchair joysticks have screens to display the condition of the system and give feedback to users. This is particularly useful for people who are visually or cognitively impaired. 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 employed the joystick will be as effective as the user is comfortable to use. It is therefore important to consider the dimensions of the buttons and their placement on the joystick to make them easy to access. It is also crucial to consider the joystick's sensitivity which can be adjusted to a variety of levels depending on the specific needs of the user.
Comfort
A joystick-controlled chair has many advantages that manual chairs do not offer. They help reduce fatigue due to operational issues and can travel for longer distances than manual chairs. They can also be used in locations with less space and more difficult terrain than a manual wheelchair such as outdoor slopes or uneven surfaces. This increased freedom allows users to experience a new freedom of movement as well as a feeling of freedom.
There are numerous different power wheelchairs available each with its distinct features. The number of bells and whistles a particular model has will depend on what the user prefers and needs. Some of the most popular features include:
Controls on an electric wheelchair equipped with a joysticks can be adapted to meet your individual requirements. This includes the kind of knob, ball or handle and the way it is mounted. Some joysticks are positioned on the top of the armrest that is dominant, while others are located in the front or back of the seat for easy access by a person who is. They can also be placed on the sides of the seat for those with limited shoulder range or muscles that are weak.
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 more accessible for those mobility wheelchair electric with poor vision. Other models provide auxiliary modes that offer audio or visual cues to help navigate. They can also offer clocks, odometers, and battery charge indicators.
Another crucial aspect of the joystick is how it can be operated within narrow turning radius. The best models will have a small turning radius, which makes it easier to maneuver around obstacles and narrow spaces such as hallways. The narrow radius makes it easier to maneuver in public areas and stores. This tight turning circle is particularly useful for people who have mobility issues, such as cerebral palsy, or other mobility issues such as multiple sclerosis, ALS and Huntington's disease, brainstem injury or spinal cord stroke.
Safety
Power wheelchairs are made with safety in mind as a priority. They have robust brake systems that can slow the speed as quickly as the user presses the joystick control. They also have anti-tip wheels at the rear that keep the chair from slipping forward.
The most popular type of joystick is a proportional control, which is similar to automobile accelerator pedals and video game controllers in that the more the joystick is moved away from its center the more quickly the wheelchair moves. These kinds of joysticks require proprioception and finger dexterity to work efficiently. 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.
Some consumers may not have enough strength to withstand the force of a joystick, even with the aid of special rigging. Certain people who suffer from spasticity could be a bit troubled because their muscles may become stiff or atrophy. In these instances, it may be better to utilize a head-control unit that converts the movements of the user's body into the commands for the wheelchair.
The size and location of the joystick's buttons is another thing to consider. If the buttons are located too far to the left or difficult to reach, it may affect the user's seating position and cause strain on their hands. If the joystick is too far back, it can be difficult to maneuver the chair or turn the wheels.
Finally, an electric wheelchair must always be operated with a seatbelt that is fastened. The most powerful wheelchairs can travel at 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 important to keep batteries charged frequently, and every night if possible. This will ensure an extended life span and will maintain their effectiveness. It is also recommended to have your chair regularly maintained to ensure that all parts are working effectively.
Accessories
Joysticks are a key component of power wheelchairs and can be upgraded with a variety of accessories. These can range from simple switches to more sophisticated interfaces that connect to communication devices, and even external environmental control units. A high-end power wheelchair is likely to have several controller components that can be used and configured to meet the needs of a specific client. For instance, a non-expandable controller will typically only accept a proportional joystick for an input device. However, an expandable controller can allow puff and sip controls, special switches and head array systems. Some of the more advanced controllers can operate up to two power seating actuators, that can alter the angle and position of the seat.
The most basic type of joystick that is commonly used in the clinic is an inverse control, often referred to as a movement sensing joystick. This kind of joystick responds to the force by boosting output (i.e. wheelchair speed) the farther the stick is pushed away from the center. This requires a significant amount of proprioception intact and dexterity for effective use.
While the technology in use today can be used to compensate for small magnitude movements that occur in EPW driving however, it is unable to detect and adjust to many more severe unintentional movements, such as those caused by larger involuntary or amplitude tremors that are not accompanied by 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 movement, many people suffering from conditions such as athetosis, MS, ALS or spinal cord injuries will not be able to safely operate an electric power chair.
Most wheelchairs have a number of different parameters that can be programmed or customized, usually with the help of a clinician. These parameters include changing the torque that is provided by the motor, changing the speed at which the chair moves and setting the dead zone which is the amount within which the EPW cannot produce an output. Some controllers also allow the clinician to save backup programs. This is helpful in an emergency or if a patient's symptoms alter.
