The Best Place To Research Self Control Wheelchair Online
Types of Self Control Wheelchairs

Many people with disabilities use self-controlled wheelchairs to get around. These chairs are great for everyday mobility and are able to easily climb hills and other obstacles. They also have large rear shock-absorbing nylon tires that are flat-free.

The speed of translation of the wheelchair was measured by a local field approach. Each feature vector was fed to a Gaussian encoder that outputs a discrete probabilistic spread. The evidence accumulated was used to trigger visual feedback, as well as an alert was sent after the threshold was reached.

Wheelchairs with hand-rims

The type of wheels a wheelchair has can impact its mobility and ability to maneuver various terrains. Wheels with hand-rims can help reduce strain on the wrist and provide more comfort to the user. Wheel rims for wheelchairs may be made from aluminum, steel, or plastic and are available in a variety of sizes. They can be coated with vinyl or rubber for better grip. Some are equipped with ergonomic features such as being shaped to conform to the user's closed grip, and also having large surfaces for all-hand contact. This allows them to distribute pressure more evenly and reduce the pressure of the fingers from being too much.

A recent study found that flexible hand rims reduce impact forces as well as the flexors of the wrist and fingers during wheelchair propulsion. They also have a wider gripping area than tubular rims that are standard. This allows the user to apply less pressure while still maintaining excellent push rim stability and control. They are available at a wide range of online retailers as well as DME suppliers.

The study's findings showed that 90% of the respondents who had used the rims were satisfied with the rims. However it is important to keep in mind that this was a postal survey of people who had purchased the hand rims from Three Rivers Holdings and did not necessarily represent all wheelchair users with SCI. The survey did not assess any actual changes in the level of pain or other symptoms. It simply measured whether people perceived a difference.

Four different models are available: the big, medium and light. The light is round rim that has a small diameter, while the oval-shaped medium and large are also available. The prime rims are also a little bigger in diameter and have an ergonomically-shaped gripping surface. All of these rims are mounted on the front of the wheelchair and can be purchased in various colors, ranging from natural- a light tan color -to flashy blue red, green or jet black. These rims are quick-release, and can be removed easily to clean or maintain. Additionally, the rims are coated with a vinyl or rubber coating that protects hands from slipping on the rims and causing discomfort.

Wheelchairs with tongue drive

Researchers at Georgia Tech have developed a new system that lets users move around in a wheelchair as well as control other electronic devices by moving their tongues. It is comprised of a small magnetic tongue stud, which transmits signals for movement to a headset with wireless sensors and the mobile phone. The smartphone converts the signals to commands that can control the device, such as a wheelchair. The prototype was tested with able-bodied people and spinal cord injury patients in clinical trials.

To test the performance, a group physically fit people completed tasks that assessed input accuracy and speed. Fitts’ law was used to complete tasks like keyboard and mouse usage, and maze navigation using both the TDS joystick and standard joystick. A red emergency override stop button was included in the prototype, and a companion participant was able to hit the button in case of need. The TDS worked as well as a normal joystick.

In a separate test that was conducted, the TDS was compared to the sip and puff system. This lets people with tetraplegia to control their electric wheelchairs through blowing or sucking into straws. The TDS completed tasks three times faster and with greater accuracy than the sip-and puff system. The TDS is able to drive wheelchairs with greater precision than a person with Tetraplegia, who steers their chair with a joystick.

The TDS was able to determine tongue position with an accuracy of less than one millimeter. It also incorporated a camera system that captured the eye movements of a person to interpret and detect their movements. Safety features for software were also implemented, which checked for the validity of inputs from users twenty times per second. Interface modules would stop the wheelchair if they did not receive a valid direction control signal from the user within 100 milliseconds.

The team's next steps include testing the TDS with people with severe disabilities. They have partnered with the Shepherd Center, an Atlanta-based catastrophic care hospital and the Christopher and Dana Reeve Foundation to conduct the trials. They plan to improve their system's ability to handle lighting conditions in the ambient, to add additional camera systems and to allow the repositioning of seats.

Joysticks on wheelchairs

With a wheelchair powered with a joystick, clients can operate their mobility device with their hands without having to use their arms. It can be positioned in the center of the drive unit or either side. It also comes with a screen to display information to the user. Some screens have a big screen and are backlit for better visibility. Others are smaller and could have pictures or symbols to assist the user. The joystick can also be adjusted to accommodate different sizes of hands grips, sizes and distances between the buttons.

As the technology for power wheelchairs has improved in recent years, clinicians have been able to develop and modify alternative controls for drivers to enable patients to maximize their potential for functional improvement. These innovations allow them to accomplish this in a manner that is comfortable for users.

For example, a standard joystick is an input device that uses the amount of deflection on its gimble in order to produce an output that grows as you exert force. This is similar to how video game controllers or automobile accelerator pedals work. However this system requires excellent motor control, proprioception and finger strength in order to use it effectively.

A tongue drive system is a different type of control that relies on the position of the user's mouth to determine the direction in which they should steer. A magnetic tongue stud sends this information to a headset which executes up to six commands. It is a great option for those with tetraplegia or quadriplegia.

Some alternative controls are more simple to use than the traditional joystick. This is particularly beneficial for users with limited strength or finger movements. Some of them can be operated with just one finger, making them ideal for people who cannot use their hands at all or have minimal movement.

Additionally, My Mobility Scooters have multiple profiles which can be adapted to each client's needs. This is important for those who are new to the system and may require adjustments to their settings periodically when they are feeling tired or have a flare-up of a condition. This is beneficial for experienced users who want to change the parameters set for a particular setting or activity.

Wheelchairs with a steering wheel


Self-propelled wheelchairs can be utilized by people who need to move on flat surfaces or up small hills. They come with large rear wheels for the user to grip as they move themselves. They also have hand rims which allow the individual to make use of their upper body strength and mobility to control the wheelchair in either a either direction of forward or backward. Self-propelled chairs can be fitted with a variety of accessories like seatbelts as well as drop-down armrests. They can also have legrests that can swing away. Some models can be converted into Attendant Controlled Wheelchairs, which allow caregivers and family to drive and control wheelchairs for people who require assistance.

To determine kinematic parameters the wheelchairs of participants were fitted with three wearable sensors that tracked movement throughout the entire week. The gyroscopic sensors mounted on the wheels and fixed to the frame were used to determine the distances and directions of the wheels. To distinguish between straight forward movements and turns, the period of time during which the velocity differs between the left and the right wheels were less than 0.05m/s was considered straight. Turns were then investigated in the remaining segments, and the turning angles and radii were calculated from the reconstructed wheeled route.

This study involved 14 participants. The participants were evaluated on their navigation accuracy and command latencies. They were asked to navigate a wheelchair through four different wayspoints on an ecological experiment field. During the navigation trials the sensors tracked the trajectory of the wheelchair over the entire distance. Each trial was repeated at minimum twice. After each trial, participants were asked to choose the direction in which the wheelchair could move.

The results revealed that the majority participants were able to complete the navigation tasks, although they did not always follow the proper directions. On the average, 47% of the turns were completed correctly. The other 23% were either stopped right after the turn, or wheeled into a second turning, or replaced by another straight movement. These results are similar to those from previous research.
