Welt belt looks like any other fashionable belt, but it is actually a fall risk assessment wearable device. Normally, you could only perform fall risk assessment in clinics once in a while. But with Welt belt, it will monitor your gait and assess your risk of fall any time, any where. It is meaningful to measure daily-life gait speed as part of your lifestyle, as it allows you to observe improvement or decline in your gait, so you could seek advice early, preventing the risk of falling.
