Powered Assistive Device for Stair Mobility

The Problem:

As a result of the growing elderly population, there is a need to provide new technology that will assist these individuals and allow them to support themselves and live alone. Current methods of stair mobility consist mainly of seated chair lifts, which are expensive to purchase and install, take up valuable space in the stairways, and users often develop a reliance on these lifts and lose the health benefits of climbing stairs.

The Solution:

Researchers at the University of Alabama have developed a compact, easy-to-install motorized device to help guide and support people ascending and descending stairs. The technology attaches to the pre-existing handrail of the stairway, and it operates using a mounted motor with a bi-directional track. The assistive device features a back brace/harness cantilevers, which prevent users from falling backwards. This invention sets out to improve on current technology that assists individuals in walking up or down the stairs.
