Electric Wheelchair With Joystick
Joysticks for power wheelchairs can enhance their use and independence. However, standard joysticks may be incompatible with the individualized features of hand disorders.
This study assessed the effectiveness and satisfaction of customized power wheelchair joysticks 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 used for evaluating.
Control
The control system of a power chair comprises two essential components which are the joystick as well as the electronics (also called the controller). Standard joysticks are mounted on the left or the right side of the wheelchair, while more sophisticated rehab chairs come with swing-away mounts which allow the joystick to slide to the middle of the seat.
The way that a joystick is installed and used will play an important role in determining whether it can be a success for a specific user. If a client is prone to tremors, it is crucial to design the joystick such that the movements do not activate the chair accidentally. Standard EPW joysticks are proportional input devices that respond to the deflection of the gimbal in order to control the chair's movement (similar to a video game controller or an accelerator in a car pedal).
There are many alternative control options for power wheelchairs, which require very little force to activate. Switch controls, sip-and puff controls, head arrays, and chin controls are all accessible. Certain of these controls require an additional interface to connect to the wheelchair. However, a lot of them are compatible with new joysticks that incorporate Bluetooth into the handles.
Some wheelchair joysticks have a screen on them to display the current 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 capability of controlling various accessories, including environmental controls and even a TV or tablet.
No matter what technology is used, a joystick will only be as useful as the user finds it easy to use. It is therefore crucial to consider the size of the buttons and their placement on a joystick in order to make them accessible. Also, it is essential to consider the sensitiveness of the joystick which can be adjusted to a range of levels according to the needs of each individual client.
Comfort
A joystick-controlled wheelchair has many advantages that a manual chair does not have. They reduce fatigue caused by operational factors and allow for longer travel distances than manual-operated counterparts. They can also be used in locations with less space and more challenging terrain than a manual one, such as outdoor slopes or uneven surfaces. This additional independence allows users to experience a new freedom of movement and feeling of freedom.
There are numerous different power wheelchairs on the market each with its own unique features. The number of bells and whistles available on a specific model will depend on the user's needs and desires. A few of the most common features include:
Controls that can be customized on an electric wheelchair equipped with the joystick is a possibility to meet individual needs. This includes the type and position of the ball, knob, or handle. Some joysticks are located on the armrest of the driver's seat and others are positioned on the front or rear of the seat to make it easier for the an attendant to reach. They can also be placed on the sides of the seat for those with limited shoulder mobility or muscles that are weak.
Other features can be more customized like the design and size of the joystick screen. Some models are backlit, or have colors that make it easier for those who have low vision to read. Some models feature auxiliary modes which provide audio or visual navigation signals. Other models could include odometers, clocks and indicators for battery charge.
Another important aspect of the joystick is how it can be controlled in narrow turning radius. The best models will have a small turning radius, making it easier to navigate obstacles and narrow spaces, such as hallways. This narrow turning radius makes it easier to navigate through public spaces and stores. This narrow turning radius is particularly beneficial for those with mobility issues such as cerebral palsy, multiple sclerosis, ALS, Huntington's disease, spinal cord injury or brainstem stroke.
Safety
Power wheelchairs were designed with safety as a priority. They have reliable brake systems that can reduce the speed as quickly as the consumer presses the joystick control. They also have anti-tip wheels in the rear to prevent the chair from tipping backwards.
The most commonly used type of joystick is a proportional control which is similar to car accelerator pedals as well as video game controllers in that the more the joystick moves away from its center the more quickly the wheelchair moves. These joysticks require finger dexterity and good proprioception to operate. A standard joystick is usually placed on the armrest, but a variety of different specific controls are available that put the control in the middle or on the side of the seat.
Even with special rigging, some consumers may not be able deflect a handle. People with spasticity might be a bit troubled because their muscles may become stiff or weak. In these cases it might be beneficial 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 buttons on the joystick is another factor to consider. If the buttons are located too far forward or are difficult to reach, it may affect the user's position and cause stress on their hands. On the other side when the joystick is placed too far backward it could be difficult to turn the wheels or move the chair through tight spaces.
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 preferably every night. This will ensure they have longer life and keep their effectiveness. It is also recommended to have your chair power chairs for disabled checked regularly to ensure that all components are operating effectively.
Accessories
The joystick is a major element of any power wheelchair, and there are numerous accessories that can be added to boost its capabilities. They can range from basic switches up to more complex interfaces that connect to communication devices and even external environment control units. A high-end power wheelchair will often have a variety of controller components that can be utilized and adjusted to meet the requirements of a particular client. For instance the non-expandable controller would typically only accept a proportional joystick as an input device, whereas an expandable controller may allow puff and sip controls, specialty switches, and head array systems. Certain advanced controllers are able to 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 called a movement sensing joystick. This type of joystick like automobile accelerator pedals and video game controllers responds to the force applied on the stick by increasing its output (i.e. The speed of the wheelchair increases as the stick is moved away from the center. This requires a good deal of dexterity and intact proprioception for effective use.
While the technology in use today can compensate for small variations in amplitude during EPW driving, it is still unable to recognize and adjust to more severe, accidental movements, such as those caused by higher involuntary or amplitude tremors that aren't associated with conscious intent like athetosis.5 As long as we don't develop and implement new technology that can reliably detect and adapt to these kinds of unintentional movements, a lot of people suffering from conditions such as athetosis, MS, ALS or spinal cord injuries won't be able safely to use an electric power chair.
Most wheelchairs have a range of different parameters that can be programmed or customized typically with the help of a clinician. These parameters can be used to alter the torque generated by the motor, and adjusting the speed of the chair. They can also be used to set the dead zone, which is the area at which the EPW will not produce an output. Some controllers also allow the clinician to save backup programs. This is beneficial in an emergency or when the symptoms of a patient change.
