As we get older, it becomes harder to stay upright and maintain good posture. This happens for many reasons, like muscles getting weaker, eyesight changing, and the body not sensing movement as well as before.
Sadly, this means that falls become more common with age. Around 40% of older people have a fall at least once every year, and falling can lead to serious injuries.
For a long time, experts have known that certain exercises that help people stay steady, called postural control exercises, can prevent falls. These exercises train the body to react quickly to unexpected changes, like if someone bumps into you while you are walking.
But there has been a big problem: the equipment needed for this kind of training is often large, expensive, and complicated. That makes it hard for regular people to get access to it unless they are in a special clinic or hospital.
Now there is some exciting news. A new study published in the IEEE Journal of Translational Engineering in Health and Medicine talks about a new device that could make balance training much easier. Assistant Professor Masataka Yamamoto and his team from Tokyo University of Science have invented something called the Wearable Balance Exercise Device, or WBED for short.
The WBED is like a lightweight harness or suspenders that you wear. It has two small artificial muscles that can gently push you to one side or the other without warning. This small push forces your body to adjust quickly, just like it would if you were bumped in real life. Over time, practicing with these little surprises can help you stay more steady and avoid falling.
The device is designed to be easy to carry, simple to use, and light enough for people to use it at home or during therapy sessions. This is a huge improvement compared to the big, complicated machines used in clinics.
To test if the WBED really works, the researchers asked 18 healthy young men to take part in a study. They divided them into two groups. One group used the real WBED, and the other group used a fake version that did not actually push them. Before and after several training sessions, the researchers measured how well each person could keep their balance when pushed.
The results showed that the men who trained with the real WBED improved their balance. They were better able to stay steady when something unexpected happened. This suggests that using the WBED can really help people improve their quick reactions and balance.
This new device could be very important for older adults and people who are in physical therapy after an injury. Regular use of the WBED could help them stay stronger and avoid dangerous falls. Plus, because it is easy to use at home, it means that people can practice their balance every day without needing to go to a special clinic.
The WBED might not only help seniors. It could also be useful for athletes who need excellent balance and quick reactions for their sports. With more research, it could become a regular part of training for many people.
As the number of older adults grows around the world, especially in places like Japan, devices like the WBED could help many people stay healthy, active, and independent for longer. It is an exciting step toward making life safer and better for everyone.
