A leading cause of disability in the United States is hemiparesis, a condition where impaired motor control, muscle weakness, and spasticity affect one side of the body. Occurring in 80% of stroke survivors, reduced mobility and decreased quality of life are challenges that impact millions of individuals.
Walking may seem like a simple activity, but it relies on complicated biomechanics. The impact of even a small loss of strength on one side of the body is multiplied as muscles on the other side engage to compensate. As a result, those with hemiparesis expend 60% more energy walking than those with a healthy gait. This means slower walking speeds, lower endurance, more pain, and a greater risk of falls.
Researchers at the University of Utah’s John and Marcia Price College of Engineering are now piloting a device that can rebalance this equation. In a paper recently published in the journal Nature Communications, the team has shown that their portable, lightweight hip exoskeleton can reduce the energy required to walk by nearly 20% in individuals with hemiparesis after stroke.
