Electric Wheelchair With Joystick
Joysticks on power wheelchairs can increase their ease of use and independence. Standard joysticks are not able to accommodate the unique features of hand dysfunction.
This study evaluated the effectiveness and satisfaction of custom-designed power wheelchair Joysticks that were manufactured using 3D printing. Modified power-mobility indoor driving assessment (PIDA), National Aeronautics and Space Administration task load index, and the psychosocial impact of assistive devices scales were used for evaluation.
Control
The control system of a power chair has two important components: the joystick and the electronic. Joysticks that are standard are placed on either the left or right side of the chair, while more sophisticated rehab chairs come with swing-away mounts that permit the joystick to be moved into the middle of the seat.
The way in which a joystick will be mounted and used is crucial to its performance for a client. If a client has a high number of tremors, it is important to design the joystick such that the movements do not cause the chair to move accidentally. Standard EPW joysticks are typically proportional input devices, which respond to the amount of deflection on the gimbal in order to control the movement of the chair (similar to an accelerator pedal or video game controller).
There are a variety of alternative control options for power wheelchairs, which require very little force to activate. Switch controls, sip-and-puff controls, head arrays, 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.
A few standard wheelchair joysticks come with screens that display the condition of the system and provide feedback to the users. This is particularly useful for those who are visually or cognitively impaired. Other advanced joysticks come with the capability of controlling many different devices like environmental controls and even a tablet or TV.
Whatever the technology the joystick is useful if it's easy for the user to use. This is why it is essential to consider the size and location of the joystick's buttons to ensure they are easily accessible. It is also crucial to take into consideration the sensitivity of the joystick that can be set to a range of levels depending on the individual needs of the client.
Comfort
A joystick-controlled power wheelchair offers many benefits that aren't available with a manual chair. They minimize fatigue triggered by operational issues and permit longer travel distances than manual-operated counterparts. They can also be used in locations that are smaller and have more challenging terrain than a manual wheelchair for example, outdoor slopes or uneven surfaces. This increased independence allows users to experience the freedom of movement and feeling of independence.
A variety of different power wheelchairs are offered with an array of options. The number of bells and whistles included on the specific model will depend on the requirements of the user and their desires. The most commonly used features include:
Customization of controls on an electric wheelchair with a joystick is possible to satisfy the individual's needs. This includes the type of knob or handle, as well as the ball or the way it is mounted. Some joysticks are mounted on the opposite side of the dominant armrest, while others are placed either on the back or front of the seat to facilitate access by an attendant. Certain joysticks can be placed on the side for people with limited shoulder range or muscle weakness.
Other features are more personal in nature like the size and shape of the joystick display screen. Some are backlit or in a color that is easier to read for those who have low vision. Some models have additional modes that provide visual or audio navigation cues. Other models could include odometers, clocks, and indicators for battery charge.
The ability of a joystick to maneuver in a small turning radius is also essential. The most effective models will have a smaller turning radius, making it easier to maneuver around obstacles and narrow spaces such as hallways. This here radius of tight turning allows for easier navigation in public places and in stores. This narrow turning radius is especially useful for people who suffer from mobility issues like cerebral palsy, MS, ALS, Huntington's disease, spinal cord injury, or brainstem stroke.
Safety
Power wheelchairs are designed with safety in mind. They have reliable brake systems that can slow the speed quickly when the consumer presses the joystick control. They also have anti-tip wheels at the rear that help keep the chair from slipping forward.
The most common type of joystick is a proportional controller, which is similar to automobile accelerator pedals as well as video game controllers in that the more the joystick is moved away from center, the faster the wheelchair moves. These kinds of joysticks require proprioception and finger dexterity to function efficiently. Standard joysticks are mounted on the armrest. However there are several special controls that place the controls on the side or middle of the seat.
Some people may not have enough strength to deflect a joystick's handle even with the aid of special rigging. Certain people who suffer from spasticity could have issues due to their muscles becoming stiff or atrophy. In these cases the use of a head control unit that transforms the movement of the head of the user into the needed command for the wheelchair might be a better choice.
Another aspect to consider is the size and location of the joystick's buttons. If the buttons are too far forward or difficult to reach, it may affect the user's position and put strain on their hands. On the other side when the joystick is placed too far backward it may be difficult to turn the wheels or maneuver the chair through tight spaces.
The seatbelt should be secured on an electric wheelchair. The most powerful wheelchairs can reach speeds of up to 8 mph and a seatbelt that isn't fastened can lead to serious injuries or death. It is also crucial to ensure that batteries are charged frequently, and every night, if it is possible. This will ensure they have an extended life span and will maintain their efficiency. It's also a good idea to get regular maintenance on your chair to make sure all components are functioning properly.
Accessories
The joystick is a major element of any power wheelchair, and there are many accessories that can be added to boost its functionality. These range from here simple switches to more sophisticated interfaces that connect to communication devices, or external environmental control units. A more expensive power wheelchair is likely to have several controller components that can be utilized and adapted to meet the requirements of a particular client. A non-expandable controller will only accept the proportional stick as an input device while an expandable model will also accept sip and puff control, special switches, as well as head array systems. Some of the more advanced controllers are able to operate up to two power seating actuators that can be used to adjust the position and tilt of the seat.
The most basic kind of joystick that is commonly used in the clinic is a proportional control, here sometimes referred to as a movement sensing joystick. This kind of joystick responds to force by increasing output (i.e. the speed of the wheelchair) the farther the stick is moved away from the center. This requires a fair amount of proprioception intact and dexterity for efficient use.
Although the technology used today can be used to compensate for small amplitude movements during EPW driving but it is not able to detect and adjust to more severe and accidental movements, such as those caused by larger amplitude tremors or involuntary movements 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, many sufferers with diseases such as athetosis, MS, ALS or spinal cord injuries will not be able to safely operate an electric power chair.
The majority of wheelchairs have a variety of different parameters that can be programmed or customized, usually with the help of a clinician. These parameters include altering the torque provided 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. Certain controllers will also be able to store backup programs, which are handy for a healthcare professional to have on hand in the event in the event of an emergency or a client with fluctuating symptoms.
