As people get older, staying balanced becomes harder. Muscles weaken, vision changes, and the body’s ability to sense movement declines. This makes falls more common, with nearly 40% of older adults experiencing at least one fall each year. Since falls can lead to serious injuries, finding ways to prevent them is essential.
Experts have long recommended exercises that improve balance, also known as postural control exercises. These exercises train people to adjust their stance when faced with sudden movements, such as a push or a stumble. The problem is that traditional balance training often requires large, expensive, and complicated equipment, making it difficult for many people to access.
A new invention by Assistant Professor Masataka Yamamoto and his team at Tokyo University of Science could change that. They have developed the wearable balance exercise device (WBED), a simple and portable tool designed to improve balance.
The WBED looks like a pair of high-tech suspenders and uses two artificial muscles to gently pull a person from side to side. These movements mimic the unexpected shifts in balance that can happen in real life, training the body to respond quickly and stay upright.
To test how well the WBED works, researchers conducted an experiment with 18 healthy men. They split them into two groups: one group trained with the real WBED, while the other used a dummy version that didn’t create balance challenges. The goal was to see if the device helped people react better to sudden shifts in balance.
The results were clear—those who used the WBED showed significant improvement in their ability to stay steady when faced with unexpected movements. This suggests that the device could help older adults, as well as people recovering from injuries, reduce their risk of falling.
The WBED’s biggest advantage is that it is lightweight, easy to use, and suitable for home use. Unlike traditional balance training equipment, which is often only available in medical or rehabilitation centers, this device can be used almost anywhere. This makes it easier for older adults and patients in physical therapy to practice balance exercises regularly.
Beyond fall prevention, the WBED could also be useful in sports training. Athletes who rely on balance and quick reflexes—such as gymnasts, skiers, and soccer players—could use the device to improve their stability and coordination.
With populations aging in many parts of the world, especially in countries like Japan, innovations like the WBED are becoming increasingly important.
By helping people improve their balance, this device could allow older adults to stay active and independent for longer. It also offers exciting possibilities for rehabilitation and athletic training, making it a valuable tool for people of all ages.
This simple yet effective invention marks an important step forward in fall prevention and balance training. With more research and development, devices like the WBED could play a key role in improving quality of life and keeping people safe from injuries caused by falls.
