Electric Wheelchair With Joystick
Joysticks on power wheelchairs can increase their ease of use and independence. However, standard joysticks may lack accommodation of individualized features of hand dysfunction.
This study examined the effectiveness and satisfaction of customized power wheelchair Joysticks that were manufactured using 3D printing. The test was conducted using modified power-mobility assessment (PIDA), National Aeronautics and Space Administration Task Load Index and Psychosocial Impact of Assistive Devices Scale.
Control
The control system of a power chair includes two key components: the joystick, and the electronic. The standard joysticks are usually mounted to the left or right sides of the chair, whereas more complex rehab chairs may feature swing-away mounts that permit the joystick to be positioned in the middle of the seat.
The way a joystick is placed and operated will play a crucial role in determining whether it will be effective for a specific client. For example, if an individual has a significant amount of tremors, then it is crucial to ensure the joystick is designed in such a way that these actions will not cause accidental activations of the chair. The standard EPW joysticks are typically proportional input devices, which react to the amount of deflection on the gimbal to control the movement of the chair (similar to an accelerator pedal or video game controller).
There are numerous alternative control options for power wheelchairs that require only a little force to activate. These include switches, sip and puff controls, head array systems and chin controls. While some of these controls require an additional interface to connect them to the wheelchair, a lot are compatible with the latest generation of joysticks, which have integrated Bluetooth into their handles.
Some standard wheelchair joysticks even have a screen on them 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 many different accessories such as the TV, environmental controls and tablet.
No matter what technology is used, a joystick will only be as effective if the user finds it comfortable to use. Therefore, it is important to consider the size and position of the buttons on a joystick to ensure they are easy to access. It is also important to think about the sensitiveness of the joystick which can be adjusted to a range of levels depending on the preferences of each user.
Comfort
A joystick-controlled power chair has many advantages not offered by a manual chair. They limit fatigue caused by operational issues and allow for longer travel distances over manual wheelchairs. They can be utilized in areas that have less space or more difficult terrain like slopes outdoors and uneven surfaces. This added freedom allows users to experience an entirely new freedom of movement and a feeling of freedom.
There are a variety of powered wheelchairs that are available each with its distinct features. The quantity of bells and whistles a particular model features will depend on what the user wants and requires. The most commonly used features include:
Controls on an electric wheelchair with joysticks can be modified to fit individual needs. This includes the design and location of the knob, ball, or handle. Some joysticks are located at the end of the armrests of the driver's seat 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 range or muscle weakness.
Other features can be more customized like the design and size of the joystick screen. Some models are backlit or have the color of a display that is easier to read for people with poor vision. Some models feature extra modes website that offer audio or visual navigation signals. They also have clocks, odometers and indicator of battery charge.
The ability of a joystick to maneuver within a narrow turning radius is also important. The best models will have a smaller turning radius, making it easier to navigate obstacles and narrow spaces like hallways. The narrow turning radius makes it easier to maneuver through public areas and stores. This tight turning radius is particularly beneficial for those who suffer from mobility issues like cerebral palsy, MS, ALS Huntington's disease spinal cord injury, or brainstem stroke.
Safety
Power wheelchairs have been designed with safety as the top priority. They have reliable brake systems that can slow the speed quickly when the user presses the joystick control. The chairs also have anti-tip rear wheels to prevent the chair from tipping forward.
The most popular type of joystick is one that is proportional. It is similar to video game controllers and automobile accelerator pedals in that it moves the wheelchair faster the further the joystick is from the center. These joysticks require finger dexterity and intact proprioception to operate. Standard joysticks are mounted on the armrest. However there are several specialty controls that mount the control on the side or middle of the seat.
Some people may not have enough muscle strength to deflect a joystick handle even with special rigging. Certain people who suffer from spasticity could have a problem due to their muscles becoming stiff or weak. In these cases it is possible to use a head-control device that converts the movements of the consumer'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 forward or hard to reach, they could affect the position of the user and cause stress on the hands. If the joystick is too far back, it could be difficult to maneuver the chair or turn the wheels.
The seatbelt must be fastened on an electric wheelchair. 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 must be charged regularly and preferably every night. This will ensure a longer lifespan and maintain their efficiency. You should also keep your chair checked regularly to ensure that all parts are operating properly.
Accessories
The joystick is an essential element of any power wheelchair and there are many accessories that can be added to improve its capabilities. These range from simple switches up to more complex interfaces that connect to communication devices as well as external environment control units. Higher-end power wheelchairs will often include a variety of controller components that can meet the requirements of different users. A non-expandable control will only accept the proportional stick as an input device, however, an expandable control can also take sip and puff control, special switches, as well head array systems. Some of the advanced controllers can operate up to two power seating actuators which can alter the seat's angle and position of the seat.
The most basic type of joystick that is commonly used in the clinic is a proportional control, sometimes referred to as a movement sensing joystick. This type of joystick, like accelerator pedals for cars 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 pushed away from center. This requires a significant amount of intact proprioception and dexterity for efficient use.
The technology used today can compensate for minor variations in amplitude when EPW driving. However, it's not able to detect and adjust for many more serious unintentional movements, such as those that result in higher amplitude tremors or involuntary movements that are not caused by conscious intent, such as athetosis.
Most wheelchairs can be customized and programmed with the assistance of a medical professional. These parameters include altering 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 distance in which the EPW will not produce an output. Some controllers allow the clinician to store backup programs. This is beneficial in an emergency situation or if a patient's symptoms alter.
