As people grow older, keeping good balance and standing steadily can become much harder. Many parts of the body slowly change with age.
Muscles lose strength, eyesight becomes weaker, and the body’s ability to sense movement and position also becomes less accurate. These changes may seem small at first, but together they can make everyday activities more difficult and increase the chance of falling.
Falls are one of the biggest health risks for older adults around the world. Experts estimate that about 40% of older people experience at least one fall every year. Some falls only cause minor bruises, but others can lead to broken bones, head injuries, or long hospital stays.
After a serious fall, some people may lose confidence in walking and moving around. This can reduce independence and affect both physical and mental health.
Because of this, researchers have spent many years studying ways to improve balance and prevent falls. One of the most effective methods is balance training, also called postural control training.
These exercises help people react quickly when they suddenly lose balance. For example, if someone bumps into a person while they are walking, the body needs to quickly adjust to avoid falling. Training the body to respond faster can help people stay safe.
However, there has been a major problem with this type of training. Many balance training systems used in hospitals and clinics are large, heavy, expensive, and difficult to use. Some require special moving platforms or complicated machines.
This means many older adults cannot easily access the training they need, especially if they live far from medical centers or cannot travel often.
Now, researchers in Japan may have found a much simpler solution. A team led by Assistant Professor Masataka Yamamoto from Tokyo University of Science has created a new wearable device designed to improve balance in an easier and more practical way.
Their research was published in the IEEE Journal of Translational Engineering in Health and Medicine.
The new invention is called the Wearable Balance Exercise Device, or WBED. Unlike the large balance machines found in clinics, the WBED is small and lightweight. It is worn on the body like suspenders or a harness. The device contains two small artificial muscles that can gently pull or push the body to the side without warning.
These sudden small movements are important because they copy what can happen in real life. A person may slip slightly, trip on uneven ground, or be bumped by another person. The body must react quickly to stay upright. The WBED trains the body to handle these unexpected situations by creating tiny surprise movements during exercise.
When the device pushes the user slightly to one side, the body automatically tries to correct itself and regain balance. Over time, this repeated practice may help improve reaction speed and body control. Researchers believe this could lower the risk of dangerous falls in the future.
The team wanted to test whether the device really worked, so they carried out an experiment with 18 healthy young men. The volunteers were divided into two groups.
One group used the real WBED device, while the other group used a fake version that did not create any pushing movements. Before and after the training sessions, the researchers measured how well each participant could stay balanced when suddenly disturbed.
The results were encouraging. The people who used the real WBED showed better balance and improved reactions compared to the group using the fake device. They became better at keeping steady after unexpected movements. This suggests the wearable training system may truly help improve balance control.
Although the study only tested healthy young men, the researchers believe the device could become especially useful for older adults in the future.
Older people often need regular balance exercises, but many cannot attend special clinics every day. Since the WBED is portable and easy to wear, it may allow people to train safely at home or during normal physical therapy sessions.
The device may also help people recovering from injuries or illnesses that affect walking and movement. Physical therapists could use it to help patients rebuild confidence and improve stability during recovery.
Researchers also think the WBED could have uses outside healthcare. Athletes in sports that require strong balance and quick reactions might also benefit from this kind of training. Sports players often need to react instantly to sudden movements, and balance exercises could help improve performance.
Japan has one of the world’s oldest populations, so preventing falls has become an important public health goal there. Many other countries are also seeing rapidly growing numbers of older adults. Simple technologies that help people stay active and independent could become increasingly valuable in the coming years.
The WBED is still a relatively new invention, and more studies are needed to see how well it works for older adults and patients with health conditions. Still, the early results are promising. By making balance training smaller, cheaper, and easier to use, this wearable device could one day help many people stay safer, healthier, and more confident as they age.
