Help us learn how to improve the health of people around the world!

The 6th Vital Sign is a global research study that uses Apple’s ResearchKit to measure a vital sign. Vital signs, like blood pressure or temperature, are measurements used by doctors and nurses to see how healthy a person is.

Walking speed has been recommended by experts as the next vital sign to be checked. Walking speed can be used to predict changes in people’s health and their ability to do day-to-day activities. It can also predict whether they may fall or need to go to the hospital.

Right now we do not have a good way to measure walking speed that is the same for everyone, but you can help! Join our global walking speed study today to help us help people all over the world.


Why It Matters

Walking speed, like blood pressure, can help us predict future health events like heart problems. But walking speed may help us predict if someone is at risk for falling or needs help getting back to their usual self.


Learn how your walking speed compares to others, and what you can do to stay healthy.
