Why is stairs functionality important for personal exoskeletons?

In a recent poll of US-based ReWalk Personal Exoskeleton users who did not currently have access to stair function in their exoskeleton, nearly 80% reported that having that access would result in an increase of the number of places they could access and an anticipated frequency in device use. The addition of stair and curb functionality to the ReWalk personal exoskeleton allows users to walk more frequently and in more locations, enabling more opportunities to achieve and maintain the clinical and wellness benefits associated with functional ambulation.
