Improving Mediolateral Walking Balance With an Assistive Exoskeleton
Medical University of South Carolina
Summary
Many people who have experienced a stroke have deficits in their walking balance. The long-term goal of this research is to develop an exoskeleton that can effectively improve walking balance, thus improving functional mobility.
Description
Walking balance is an important component of functional mobility, with post-stroke balance deficits contributing to a fall rate more than double that of age-matched controls. Unfortunately, traditional therapy approaches have not succeeded in addressing balance deficits or reducing fall risk, motivating the use of technology to fill this gap. Although assistive exoskeletons are a promising approach to improve post-stroke mobility, they have generally not been designed to control walking balance and agility. This limitation is a particular concern in the development of devices for people with s…
