Electric Wheelchair With Joystick
Joysticks on power wheelchairs can significantly increase the user's independence and make it easier to use. However, standardized joysticks can lack accommodation of individualized features of hand impairment.
This study examined the efficacy and satisfaction of customizing 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 employed to evaluate.
Control
The control system of a power wheelchair comprises two key components: the joystick and the electronics (also called the controller). Joysticks that are standard are placed on either the left or right side of the wheelchair, whereas more advanced rehab chairs feature swing-away mounts that permit the joystick to be moved into the middle of the seat.
The way a joystick is mounted and used is a significant factor in determining if it will be effective for a specific customer. For instance when a person has significant tremors, it is crucial to ensure the joystick is constructed in such a way that the movements will not trigger accidental activations of the chair. Standard EPW joysticks are proportional input devices that react to the deflection amount of the gimbal in order to control the chair's movements (similar to an electronic game controller or a car accelerator pedal).
There are a number of different alternative control options for power wheelchairs that require little force for activation. Switch controls, sip-and puff controls head arrays, sip-and-puff controls, and the chin controls are all there. While some of these controls require a separate interface to connect them to the wheelchair, many are compatible with the new generation of joysticks that have integrated Bluetooth into their handles.
Some standard wheelchair joysticks have a screen to show the state of the system and also to provide feedback to the users. This is particularly useful for people who are cognitively or visually impaired. Other advanced joysticks come with the ability to control a variety of accessories like environmental controls and even a TV or tablet.
No matter what technology is employed, a joystick will only be as useful as the user is comfortable to use. It is therefore essential to think about the dimensions of the buttons and their position on a joystick in order to make them easy to access. Also, it is essential to think about the sensitivity of the joystick, which can be adjusted to a range of levels according to the requirements of each client.
Comfort
A joystick-controlled chair has many advantages that a manual chair does not offer. They reduce fatigue caused by operational factors and allow for longer travel distances than their manually operated counterparts. They can also be used in areas with fewer spaces and more challenging terrain than a manual one, for example, uneven surfaces or slopes in the outdoors. With this added mobility users will experience the freedom of movement that brings new life to their lives and reminds them of how great it is to be independent again.
There are many different power wheelchairs available, each with their distinct characteristics. The amount of bells and whistles on the specific model will depend on the needs of the user and wants. Some of the most popular features include:
The control options on an electric chair with a joystick can be made to meet the needs of each individual. This includes the kind of knob or handle, or ball, and the manner in which it is mounted. Some joysticks can be found at the end of the armrest of the driver's chair and others are positioned on the rear or front of the seat to make it easier for the attendants to reach. Some joysticks can be positioned on the side for those who have limited shoulder mobility or a weakness in their muscles.
Other features are more personalized like the design and size of the joystick screen. Some models are backlit or have colors that are more accessible for those who have low vision. Certain models come with extra modes that offer audio or visual navigation indicators. Other models may include clocks, odometers and indicators of battery charge.
The ability of a joystick to maneuver in a limited turning radius is also crucial. The most effective models will have a small turning radius, making it easier to maneuver around obstacles and narrow spaces like hallways. The narrow turning radius allows for easier maneuvering in public spaces and in stores. This tight turning circle is particularly beneficial for those suffering from mobility issues, like cerebral palsy, or other mobility issues such as multiple sclerosis ALS and Huntington's disease, brainstem or spinal cord injury stroke.
Safety
Power wheelchairs were created with safety as a priority. They have reliable braking systems that can reduce speed swiftly when the user presses the joystick control lever. They also have anti-tip wheels in the rear that help prevent the chair from tipping forward.
The most popular type of joystick is a proportional controller, which is similar to car accelerator pedals and video game controllers in that the more the joystick is moved away from center, the faster the wheelchair moves. Joysticks that require finger dexterity and a healthy sense of proprioception. A standard joystick is placed on the armrest however, a variety of specific controls are available that mount the controls in the middle or at the sides of the seat.
Certain people might not have enough muscle strength to deflect a joystick's handle even with the aid of special rigging. Some people with spasticity may have issues because their muscles can become stiff or atrophy. In these cases it might be beneficial to use a head-control device that converts the movements of the user's body into the commands for the wheelchair.
Another thing to take into consideration is the size and location of buttons on the joystick. If the buttons are far to the left or difficult to reach, they could hinder the position of the user and create a strain on the hands. If the joystick is too far back, it could be difficult to maneuver the chair or turn the wheels.
The seatbelt should be fastened on an electric wheelchair. Seatbelts must always be fastened when using an electric wheelchair. The fastest wheelchairs can travel as fast as 8mph. Batteries should be charged frequently and at least every night. This will allow them to live longer and ensure their efficiency. It's also an excellent idea to schedule regular maintenance on your chair to ensure that the components are in good working order.
Accessories
The joystick is a key element of any power wheelchair, and there are numerous accessories that can be added to boost its performance. These range from simple switches, to more advanced interfaces that connect to communication devices, and even external environmental control units. A more expensive power wheelchair will often have various controller components that can be utilized and adjusted to meet the requirements of a specific client. For example the non-expandable controller would generally only accept the proportional joystick as an input device while an expandable controller can allow puff and sip controls, specialty switches and head array systems. Some of the more advanced controllers are capable of operating up to two power seating actuators which can adjust the position and angle of the seat.
The most common type of joystick that is prescribed in clinics is a proportional joystick, also known as a movement-sensing joystick. This type of joystick, similar to accelerator pedals in cars and video game controllers, responds to the force that is exerted on the stick by increasing its output (i.e. wheelchair speed) the farther the stick is moved from center. This requires a lot of dexterity and a healthy sense of proprioception for effective use.
While the technology in use today can compensate for small magnitude movements that occur in EPW driving, it is still unable to detect and adjust to many more severe unintentional movements, like those caused by larger involuntary or amplitude tremors that are not accompanied by conscious intention, such as athetosis.5 In the meantime, until we create and implement new technologies that are able to reliably detect and adapt to these kinds of unintentional movements, many people power chairs for disabled suffering from conditions such as athetosis, MS, ALS or spinal cord injuries won't be able safely to use an electric power chair.
The majority of wheelchairs have a variety of different parameters that can be programmed and customized, usually with the help of a clinician. These parameters can be used to alter the torque produced by the motor, and adjusting the speed of the chair. They can also be used to determine the dead zone, which is the area at which the EPW will not produce an output. Some controllers permit the clinician to store backup programs. This is helpful in an emergency situation or when a patient's symptoms change.
