Electric Wheelchair With Joystick
Power wheelchairs with joysticks can greatly increase the user's independence and make it easier to use. However, standard joysticks may not accommodate the specific needs of hand disorders.
This study assessed the effectiveness and satisfaction of custom-designed power wheelchair joysticks that were made using 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). Standard joysticks are mounted on either the left or right side of the chair, while more advanced rehab chairs feature swing-away mounts that allow the joystick to slide into the middle of the seat.
The way a joystick is mounted and used will play a crucial role in determining whether it will be a success for a specific user. If a person has a high number of tremors, it is essential to design the joystick so that the movements don't activate the chair accidentally. The standard EPW joysticks generally use proportional input devices that react to the amount of deflection on the gimbal to regulate the movement of the chair (similar to an automobile accelerator pedal or video game controller).
However, there are now numerous alternative control options available for power wheelchairs that require very minimal force to activate. Controls for switches, sip-and-puff, head arrays, and chin controls are all accessible. Certain of these control systems require an additional interface to connect to the wheelchair. However, a lot of them are compatible with new joysticks which incorporate Bluetooth into the handles.
Some standard wheelchair joysticks even come with a screen to show the status of the system and provide feedback to the user, which is especially useful for people with visual or cognitive impairments. Other joysticks with advanced technology have the ability to control a variety of accessories like environmental controls and even a tablet or TV.
No matter what technology is used, a joystick is only useful if it's comfortable for the user operate. It is therefore essential to consider the dimensions of the buttons and their position on the joystick to make them easily accessible. It is also crucial to take into consideration the sensitivity of the joystick which can be adjusted to a range of levels depending on the individual needs of the client.
Comfort
A joystick-controlled power chair offers many benefits that aren't accessible with a manual chair. They limit fatigue caused by operational issues and permit longer travel distances than their manually operated counterparts. Additionally, they can be used in areas with fewer spaces and more challenging terrain than a manual wheelchair, like outdoor slopes or uneven surfaces. With this added mobility, users can experience an ease of movement that gives new life to their lives and reminds them of how great it is to be independent again.
There are a variety of powered wheelchairs that are available, each with their distinct features. The amount of bells and whistles a particular model features will depend on what the user prefers and requires. The most commonly used features include:
Controls on an electric wheelchair that have a joysticks can be modified to meet your individual requirements. This includes the type of knob or handle, or ball, and how it is mounted. Some joysticks are located on the armrest of the driver's chair, while others are placed on the rear or front of the seat to make it easier for the attendants to reach. Certain joysticks can be placed on the side of the seat for those who have limited shoulder range or muscular weakness.
Other features are more personal to you, such as the size and design of the joystick display screen. Some models are backlit or have colors that make it easier for those who have low vision to read. Some models feature additional modes that provide audio or visual navigation indicators. They also have clocks, odometers, and battery charge indicators.
The ability of a joystick to maneuver in a small turning radius is also important. The most effective models will have a narrow turning radius, making it easier to navigate obstacles and narrow spaces, such as hallways. This narrow turning radius allows for easier navigation in public places and in stores. This tight turning radius is especially useful for people who have mobility issues, such as cerebral palsy, MS, ALS Huntington's disease spinal cord injury, or brainstem stroke.
Safety
Power wheelchairs are designed with safety in mind. They have braking systems that are reliable that reduce speed quickly when the consumer depresses the joystick control lever. The chairs are also equipped with anti-tip rear wheels to prevent the chair from tipping forward.
The most commonly used type of joystick is one that is proportional. It is similar to video game controllers and automobile accelerator pedals in that it accelerates the wheelchair the further the joystick is away from the center. These kinds of joysticks require proprioception and finger dexterity in order to operate effectively. Standard joysticks are mounted on the armrest. However there are several specialty controls that mount the control on the middle or side of the seat.
Certain people might not have enough muscle strength to withstand the force of a joystick, even with attendant controlled electric wheelchair special rigging. Some people with spasticity may have a problem because their muscles can become stiff or weak. In these instances, a head control unit that converts the movement of the consumer's head into the required instructions for the wheelchair may be a better option.
Another factor to consider is the size and location of buttons on the joystick. If the buttons are too far forward or are difficult to reach, it may affect the user's position and result in strain on their hands. On the other side, if the joystick is placed too far backwards it could be difficult to turn the wheels or move the chair into tight spaces.
Lastly, an electric wheelchair is best used with a seatbelt secured. The most powerful wheelchairs can travel at speeds up to 8 mph, and an unfastened seatbelt can result in grave injuries or even death. Batteries should be charged regularly and preferably every night. This will ensure that they have a longer lifespan and maintain their efficiency. It's also a good idea to get regular maintenance on your chair to make sure all parts are working properly.
Accessories
Joysticks are an essential element of power wheelchairs and can be upgraded by adding a variety. They can range from basic switches to more sophisticated interfaces that connect to communication devices and even external environmental control units. A high-end power wheelchair usually comes with a variety of controller components that can be utilized and adjusted to meet the needs of a particular user. A non-expandable control can only accept a proportional stick as an input device, while an expandable one can also take sip and puff controls, special switches, as well head array systems. Some of the more advanced controllers can also operate up to 2 power seating actuators that can be used to adjust the position and tilt of the seat.
The most basic type of joystick commonly prescribed in the clinic is a proportional control, sometimes called a movement sensing joystick. This type of joystick, like automobile accelerator pedals and video game controllers, responds to the force exerted on the stick by increasing its output (i.e. the speed of the wheelchair) the farther the stick is moved from the center. This requires a fair amount of proprioception intact and dexterity for effective use.
The technology of today can compensate for minor movements in amplitude during EPW driving. However, it's not able to detect and adjust for many more extreme unintentional motions such as those caused by tremors with greater amplitude, or involuntary movements that are not related to conscious intent like athetosis.
The majority of wheelchairs can be programmed and customized with the assistance of a clinician. These parameters include altering the torque generated by the motor and altering the speed of the chair. They can also be used to set the dead zone, which is the amount of time that the EPW isn't able to produce output. Some controllers also permit the clinician to store backup programs. This is beneficial in an emergency situation or when a patient's symptoms alter.
