The Apple Watch can accurately determine a user's "frailty," according to the findings of a recently-published study from Stanford University (via MyHealthyApple).

Frailty can be determined using a six-minute walking test (6MWT), and the metric is a general standard used to evaluate the functional mobility and exercise capacity of a patient. Higher scores indicate "healthier cardiac, respiratory, circulatory, and neuromuscular function," according to Apple.

Conducted by Stanford University researchers and funded by Apple, the study provided 110 Veterans Affairs patients with cardiovascular disease with an iPhone 7 and Apple Watch Series 3. Patients conducted regular at-home six-minute walking tests, which were then compared to their standard in-clinic 6MWT performance.

The study found that an Apple Watch was able to accurately assess frailty with a sensitivity of 90 percent and specificity of 85 percent when supervised in a clinical setting. When assessed in an unsupervised setting at home, the Apple Watch was able to accurately assess frailty with a sensitivity of 83 percent and specificity of 60 percent.

The findings indicate that passive activity data gathered by the Apple Watch is an accurate predictor of in-clinic 6MWT performance.
In this longitudinal observational study, passive activity data acquired by an iPhone and Apple Watch were an accurate predictor of in-clinic 6MWT performance. This finding suggests that frailty and functional capacity could be monitored and evaluated remotely in patients with cardiovascular disease, enabling safer and higher resolution monitoring of patients.
While the study used a specially-developed app called "VascTrac" to gather 6MWT data alongside the Apple Watch's passively-collected activity data, Apple has since included a series of new mobility-related health metrics in watchOS 7, including the 6MWT. It is likely that preliminary data from studies such as this encouraged Apple to add the metrics in watchOS 7.

The research may urge healthcare providers to offer at-home assessment of functional capacity in cardiovascular disease patients using an Apple Watch.

Debunking posts where the poster doesn't seem to read the article is a full-time job.

However, as others have said, it's interesting the tidbits related to health that comes out regarding the Apple Watch.

interesting ... the more sensors we get in the watch, the more we will learn about our bodies, there's yet so much to explore ... and also hoping that these kind of data will be "explainable" to an average user and not just health care professionals
And the more about how our health is. Believe it or not, Apple Watches make people live longer and keep them in good health.

My wife and I have been trying to convince her mom to let us get her a Watch, given she has both heart issues and has fallen twice in the past couple of years, with the most recent fall requiring her to live with us for 3 months for recovery. She’s back home again, so I should just get her one for our piece of mind.
I really that her heart issues go away. Love from me.

Well, AW helps to collect data, someone needs to interpret it and then that data CAN help you make choices... AW in itself is a data collector, nothing else, people decide what to do with that data

Do it. Worst case scenario is she doesn’t wear it. It’s cheap for the convenience and peace of mind it will give you if she decides to use it. It can be hard convincing older folks to adapt to new tech but it’s worth a try.

It is generally something about "statistics". If you monitor values in an accurate manner, you will detect a development. Be it positive or negative.

The good thing: We are monitoring values over a long period, we dit not monitor that close before.
The even better thing: If a value goes "down", you have the opportunity to do something against it.

I discovered a climbing cardiofitness in my values. Just by walking a bit more (I am usually lazy...). Great. I will go on with that and walk even (a bit...) more.

All in all: Great :)
