Powered Wheelchairs- Driving Options

Although the Wheelchair has not significantly changed over the past 10 years, the technology that allows them to operate has.  There is a saying in our company, if a person has any consistent independent movement and the desire, we will get them mobile. 

Even with all the negative pressures in the Medical industry, innovation is no longer limited by the big four wheelchair producers. There are many switch and electronic companies that lead the charge in offering more creative ways to drive powered mobility.  Additionally many universities have gotten involved and have been stretching the options....from using an Ipad, eyegaze and video game controllers to EEG, and Voice Control.

Traditionally the joystick has been used to operate a powered wheelchair. When users could not control a joystick, there was switch control and sip and puff.  Later head control using proximity switches and modified head joysticks.  Modifying a joystick to be mounted on a arm or footrest was common.  In the past decade, fiber optics, magitek, light touch joystick has been used. More recently game controllers (ie PS4 and Xbox) have been converted to allow individuals to drive their powered wheelchairs with these systems. Many of the new technologies that are emerging are adapters, and supports to hold current control devies.

In the past few years, we have seen the Wii balance board used as a input device for children who when lean, can control a powered wheelchair.  Although this is not yet in the market place it certainly offers a wider range of options for those who have limitations in access or those who do not understand movement through space.   We are seeing many universities experiment with EEG as when you communicate and think, the waves are consistent and can be converted into a signal in which to drive a powered wheelchair.  Speech communication has also been used to drive a powered wheelchair.   Most recently, a university has been piercing people's tongues using it as a way to drive a powered wheelchair.

Unfortunately most of these newer technologies have not yet become commercially available or even made it through FDA consideration.  All these technologies are exciting for people who have lost the ability to move independently.  It is truly exciting to see more and more options available which will allow more access and integration.

We are really excited to see people thinking outside the traditional box, and are  looking forward to these new technologies that will enable more people to drive and be independent.
