As people get older, staying steady on their feet becomes harder. Muscles weaken, vision changes, and the body’s ability to sense movement slows down. This makes falls more likely, and that’s a big worry—about 40% of older adults fall at least once every year.
These falls can lead to broken bones and other serious injuries. That’s why finding simple ways to prevent falls is so important.
Experts have known for a long time that certain exercises can help people keep their balance. These exercises train the body to react quickly and stay upright, even when something unexpected happens—like being bumped or pushed.
But there’s been one problem: most balance training equipment is big, heavy, and expensive. That means people usually have to visit a special clinic or center to use it.
Now, a team from the Tokyo University of Science, led by Assistant Professor Masataka Yamamoto, has come up with something new: a small, wearable device that helps people train their balance almost anywhere. It’s called the WBED, which stands for wearable balance exercise device.
It looks a bit like a pair of high-tech suspenders and works by gently pulling the person wearing it from side to side using two soft, artificial muscles. These light pulls create unexpected movements, just like what might happen in daily life, and help the wearer learn how to stay upright without falling.
The best part? The WBED is easy to use, portable, and doesn’t need a lot of space or complicated setup. That makes it perfect for use at home or during physical therapy sessions.
To see how well it worked, the research team tested the device on 18 healthy men. They split them into two groups: one group trained using the real WBED, and the other used a fake version that didn’t actually move. After the training period, they tested everyone’s balance again.
The results were clear: the people who trained with the real WBED showed big improvements in how quickly and effectively they could react to unexpected shifts in balance. This shows that the WBED really works—it helps the body learn how to make fast corrections and stay upright, even during sudden movements.
Why does this matter? For older adults, using the WBED regularly could mean fewer falls and greater confidence while walking or standing. It could also help people going through physical therapy after an injury or surgery. Because the device is easy to use and doesn’t require a visit to a clinic, more people can include this type of balance training in their daily routine.
But the uses for the WBED don’t stop with seniors or rehab patients. Athletes could also benefit. In sports, balance and quick reflexes are key. This wearable could help them improve their stability and coordination during training, possibly helping them perform better and avoid injuries.
As the global population continues to age—especially in countries like Japan, where many people are over 65—devices like the WBED could play a big role in helping people stay independent and safe.
This new invention offers a smart, practical way to prevent falls and improve quality of life, not just for older adults but for anyone who wants better balance. It’s a simple idea with the potential to make a big difference.
