Research indicates that Apple Watch is effective in testing physical functions Stanford University: 90% accuracy

Stanford University in the United States published a research report that pointed out that the new Apple Watch can accurately test human functions in a walking test for veterans suffering from cardiovascular disease with an accuracy of up to 90%.

For 110 veterans with cardiovascular diseases, Stanford University put on Apple Watch Series 3 smart watches and used them together with iPhone 7, and collected data with the dedicated App VascTrac to understand the accuracy of this combination for the physical function tests of these patients Sex. The tester performed a 6-minute walk test with this device.

After the 6-minute walk test, a score will be given. The higher score indicates healthier heart, breath level, circulatory system, and neuromuscular function. The researcher used the scores obtained by this device to compare with the scores of the same test performed by the tester in the clinic.

The results of the study found that the Apple Watch achieved 90% accuracy and 85% specificity in a clinical environment . Even under unsupervised testing, the Apple Watch has an accuracy of 83% and a specificity of 60%.

The 6-minute walk test has been regarded as the gold standard for measuring body functions and has been added to watchOS 7. Since Apple Watch is not a medical grade product, you should seek medical advice as soon as possible if you experience physical discomfort.
