“Usual walking speed” is a risk indicator for preventing dementia.
There is also evidence that maintaining and improving it reduces the risk.
However, because changes occur very slowly,
it is necessary to have both
① a mechanism that can pinpoint the speed, and
② automatic measurement that does not require the user to be aware of the measurement,
in order to detect small changes of around 3%, which is the original purpose of risk indicators.
Other apps do not meet these conditions in principle, and are therefore unable to correctly detect changes in the indicator.

Walking speed predicts cognitive decline: universal significance across races
Gait speed is a good predictor of cognitive decline and dementia. In this study, we conducted a meta-analysis of 17 longitudinal studies that reported these findings, and found that the risk ratio for cognitive decline was 1.89 (95% CI = 1.54-2.31) for cognitive decline compared to the fast walking speed group. reported that it was 1.66 (1.43-1.92) for patients with severe symptoms. These studies originate from the United States (12), as well as Italy, Sweden, China, Japan, and Israel (1 each), suggesting that the significance of walking speed is universal and transcends race. In the future, it is desirable to establish gender-, age-, and race-specific cutoff values.

If your walking speed is slow at the age of 45, you may think that it is simply due to your personality or habits, but some academic papers show that slow speed indicates that your physical function declines, signs of aging are noticeable, your brain is aging, and your healthy life expectancy is short.
- Even if you know just when you see the signs of dementia…
- Rare to grasp the risks objectively at an early stage.
- In so many ways to be healthy, yours really effective?
The academic paper has been published that clarifies the basis for this.
（as a predictive indicator of dementia risk）
- Usual Walking Speed ≠ Speed measured each time
- Improvement/Deterioration is unclear when measuring each time
(People tend to walk fast when measuring and the value changes every time.)
Numerous academic papers examining the relationship
Not reducing usual speed is important for dementia prevention
Also a predictive indicator of stroke/heart disease risk, sarcopenia, falls, healthy life expectancy
And a relationship between speed in middle age and healthy life expectancy
（To be overtaken means already on a downward）
(Don’t overlook slight declines, confidence with slight improvements!)
- Don’t be fooled by normalcy bias,
- Accept the fact that the speed declines, Early action to recover!
- Walking speed can be restored. Such as an amazing recovery case of a 90 year old.
- diet, exercise, communication and social activities.
- one’s physical condition, lifestyle are different, so the optimal method also vary.
- The way you walk of the same steps differs the effect.
- Have you confirmed the effect of your supplements and health foods?
- one’s physical condition, lifestyle are different, so the optimal method also vary.
- Usual Walking Speed give you a reliable way to stay healthy ！
- a health method that decline your speed really ok?
- Does the speed that decreased in the summer recover in the fall?
（Have a reliable way to stay healthy with the app!）
- If you maintain and recover your speed towards your goal, OK
- Tendency to decline needs review your health regimen, and check!

Screens of Usual Speed Diagnosis
（Installation of the iOS version）
Search this free app “Usual Speed Diagnosis” in App Store.
At first, please allow to use motion data and wait several seconds, your usual walking speed for the past 5 days will be displayed.
It is advisable to open the app at least once every 5 days.
By using the shortcut app on your iPhone, you can automatically measure your usual walking speed at the same time every day.
The measured value of usual walking speed fluctuates slightly depending on the daily situation, so it is recommended to continue measuring for about 4 weeks to accurately measure normal walking speed.
Normally, usual walking speed does not change over a period of one or two months, so please measure it every season and continuously for at least three years.
（Installation of the Android version）
Search for “Usual Speed Diagnosis” in the Play Store.
This app runs on the Android version 15 OS.
To ensure continued stable operation, open [Settings]-[Apps]-[UsualSpeedDiagnosis]-[Notifications] and slide [All Notifications for UsualSpeedDiagnosis] and [Allow Notification Dots] to the right. After a while, a circle will appear in the upper right corner of the icon, indicating that it is running.
(How to use of Android version)
The app will continue to measure automatically all day, but the OS will occasionally stop the app to save power. Please check that it is working from time to time.
If the count increases after a few tens of seconds of walking, then it is working properly.
The count is slightly different from the number of steps, but if the count does not increase even after walking, the app has stopped. However, since you opened the app, it should start working again.
If the count does not increase even after walking repeatedly, it is likely that your model is not compatible with this app.
Calculations are made early each morning, so there will be no measurement values on the first day.
Even models with a low number of daily measurements should be evaluated based on around three months of measurement data, so please continue using it patiently.
For models with a colored ● on the app icon, if the ● disappears the app has stopped so tap the icon to open it and restart it.
