Wheelchair

A wheelchair is a device used by a person who is unable to walk or suffers from other ailments or disabilities.

Melora Pazlar had to use a wheelchair on Deep Space 9, due to her anti-gravity unit being unusable. 

In 2377, Ro Laren briefly used a wheelchair when she was recovering from the injuries inflicted on her by Taran'atar. Doctor Tarses was angry she was not using the exoframe supports he had given her.
