How Biomechanics is Moving Nebraska Forward

It’s morning. Your alarm clock blares its wake-up call. You sit up, reach to turn it off, swing your feet over the side of the bed and stand up. You walk to the bathroom, taking step after step. You brush your teeth, moving the toothbrush back and forth. Up and down. You bend over to rinse.

All this movement—involving muscles, brain, senses and environment—takes place in the span of minutes and continues to happen as you go about your day. Yet, the majority of us never think about how we move. But for Dr. Nick Stergiou and his visionary team at the University of Nebraska Omaha, it’s all they research—biomechanics, which is the study of human movement, and the forces that produce it.

Most of us never think about how we move, or how natural is it for us.

But why?

If Stergiou and his team’s previous groundbreaking research is any indication, their work is vital to those suffering from movement-related disorders. Their lab incorporates principles from engineering, physiology and mathematics to understand the complexity of how humans integrate muscles, nerves, and the environment to accomplish movement. 

Breakthroughs in Helping People Move Again

Stergiou’s work isn’t just about creating groundbreaking inventions. It’s about bettering lives. His research has impacted the training techniques of surgeons, as well as the treatment of health conditions like peripheral arterial disease.

As director of the Biomechanics Research Building at UNO, Stergiou heads a team of faculty who study areas such as gait rehabilitation, fall prevention and improving physical function for the elderly.

One example is researcher Nate Hunt, who studies balance in adults—especially what causes people to slip. He watches when people slip, then studies their reactions, knowing there are good and bad responses. How animals move and stabilize themselves can provide direction. Hunt studies the interaction between fox squirrels’ cognitive and movement control capabilities, how their bodies are built, and how those capabilities interact to allow the squirrel to move as it does. He then looks at what humans can learn from fox squirrels to improve the way they get about—and, most importantly, get about without falling.

Collaborators, Inventors and Innovators

Not only do Stergiou and his team help individuals with movement-related pathologies, they support community collaborations related to exercise physiology, physical activity, and sports medicine. Stergiou also leads a department of innovators who—through the study of motion—invent devices to solve health-related challenges. For instance, robotic shorts that make running easier, 3D-printed prosthetics that save families thousands, or a “gait analysis system” than can predict your risk of a dangerous fall.

The Biomechanics Research Building houses an intriguing collection of labs and research environments—all of which are geared toward studying the mechanical laws relating to the movement or structure of living organisms. Here are just a few:

  • A virtual reality laboratory, equipped with a treadmill that has 6 degrees of freedom of movement—not only up and down, but sideways as well.
  • A machine shop large enough for people to drive their vehicles inside. Not to have their oil changed, but to have sensors installed that will assist scientists studying how we drive when we get older. Scientists can track acceleration time for older motorists and the types of abrupt reactions they make while driving, which will determine who should drive and who shouldn’t. 
  • An underwater treadmill that allows scientists to test the effects of gravity at different levels other than the earth’s 9.8g. Scientists can study, for example, how buoyancy and subsequently decreased gravity could help rehabilitate injuries by determining how much weight the joint can bear.

Finally, the building has a laboratory with 3-D printing capabilities, used to build prostheses for children with congenital deformities. Congenital deformities create an imbalance in a person’s brain; a prosthesis could impact the way the brain works. The laboratory houses a 3-D printer that, instead of plastic, creates in metal.

From the Lab to the Marketplace

Beyond improving the quality of life for so many patients, these inventions are getting noticed on a commercial level. Since growing from a small laboratory to a 57,000-plus square-foot facility, UNO’s biomechanics program was awarded the UNeMed Innovator of the Year award. UNeMED—established in 1991 by the Board of Regents of the University of Nebraska—helps push innovations beyond the laboratory and into the marketplace.

The 23,000 square-foot Biomechanics Research Building opened at UNO in 2013. It was funded with two of the largest research grants in UNO history—worth more than $10 million each.

“All these inventions produce an economic engine in terms of jobs and in terms of growth,” Dr. Stergiou said. Four biotechnology companies are looking to locate in the Biomechanics Research Building. “They want to work side-by-side with our people, shouldering in research greatness.”

In an economic analysis from the UNO Department of Economics, it was estimated that the center brought an economic impact of $1.5 million to the Omaha metropolitan area in its first two years of operation. And that number will only rise.

Creating Momentum in Biomechanics

When Nick Stergiou began teaching at UNO in 1996, the word “biomechanics” wasn’t part of the university’s lexicon. He has since secured two of the largest research grants in UNO history—National Institutes of Health grants worth more than $10 million each—and a private gift to build the 23,000-square foot Biomechanics Research Building.

The building, home to the first center in the world dedicated exclusively to research in human movement, opened in 2013. After Stergiou’s programs outgrew the original space, it underwent a 30,000 square-foot expansion, made possible with another private gift.

“It motivates me immensely to help young people to have wonderful careers and make a difference. When I see our students come up with new therapies, new interventions, new ways to help other people—it’s very rewarding.”

— Dr. Nick Stergiou

The added space translates to eight additional research labs, a data processing center, and workspace for the 13 faculty members, 35 undergraduate students and 25 graduate students who call the building home. The second, record-breaking grant he obtained in 2019 provides biomechanics students with a chance to conduct cutting-edge research alongside senior clinical NIH-funded scientists. It also enables the department to bring additional funded investigators from various disciplines to UNO’s campus.

Stergiou says the department isn’t done growing—a theme he repeats often.

“If anyone thinks we are finished, I beg to differ.”
