Joysticks recalled after power wheelchairs move on their own, injuring a patient
The U.S. Food and Drug Administration is warning that a firmware issue on a line of electric wheelchair components could cause the units to unexpectedly move even while occupied, possibly resulting in serious injury or death.
The issue has been acknowledged by manufacturer Mo-Vis BVBA, which has already begun correcting the R-net joysticks used on a variety of power wheelchairs. A firmware update correcting the malfunction has been released. However, anyone in possession of a joystick still operating on version 2.3 or lower will need to seek an upgrade immediately to avoid danger.
The joysticks are inserted into the control boxes, allowing users to control movement with their hands, unlike standard control boxes. The faulty firmware can create false readings when the chair is in a neutral position, propelling it forward.
One injury has been reported as linked to the defect. Luckily, there have been no known fatalities.
What is being recalled?
Multiple lines of joysticks were shipped with the defective firmware. Version 2.6 has been deemed safe to use. All users in possession of any affected device should check to ensure they have the proper updates installed.
Next steps
Mo-Vis sent all affected customers an Urgent Medical Recall notice on July 10, recommending they perform a software upgrade of the device during the next scheduled annual maintenance of the joystick, regardless of the firmware currently installed.
Those with joysticks operating on version 2.3 or lower will need to seek the upgrade immediately. For instructions, email the manufacturer at [email protected]
