Article Abstract
Background: The validity of the Apple Watch to measure the heart rate (HR) and oxygen saturation (Spo) for patients with chronic diseases such as diabetes mellitus (DM), dyslipidemia, and hypertension is still unclear. Therefore, this study aims to investigate the accuracy of the Apple Watch in measuring the Spo and HR in patients with chronic diseases.
Methods: Forty-one patients with chronic diseases, including 20 with hypertension, 10 with diabetes, and 11 with dyslipidemia, completed a cross-sectional study. All participants used the Apple Watch against the Polar chest strap and the pulse oximeter at rest and during moderate intensity exercise sessions to measure HR and the SpO2 at rest for 5 minutes, during exercise for 16 minutes, and followed by 3 minutes of rest. The HR was measured during all previous periods, but evaluation of the Spo included 5 measures, done only before and after exercise, with a minute interval between each measure.
Results: Overall, a strong correlation exists between measuring the SpO2 using the Apple Watch against the pulse oximeter (Contec) at rest (r = 0.92, p < 0.001) and after exercise (r = 0.86, p < 0.001) in all patients. The HR had a very strong correlation between the Apple Watch and the Polar chest strap (r = 0.99, p < 0.001) in all patients. There was no significant difference (p = 0.76) between the twenty-seven white and fourteen brown-skinned patients.
Conclusion: The Apple Watch is valid to measure the HR and SpO2 in patients with chronic diseases.

The validity of Apple Watch for measuring heart rate (HR) and oxygen saturation (SpO) in patients with cardiac diseases is still unclear. Therefore, this study aimed to investigate the accuracy of the Apple Watch in measuring HR and SpO in patients with cardiac diseases. A cross-sectional study recruited 260 cardiac patients, including 190 with regular heart rhythm and 70 with cardiac arrhythmia.

Background: Total knee (TKA) and hip arthroplasty (THA) effectively treat end-stage osteoarthritis by restoring mobility and reducing pain; however, it is unclear how balance and steadiness compare between TKA and THA patients. This study utilized wearable technology to objectively compare functional recovery between TKA and THA patients.
Methods: Two Hundred Nine patients underwent TKA (n = 152) or THA (n = 57) and were followed for 1 year.
Background: Digital health technologies can potentially improve clinical research efficiency and increase participant diversity but have challenges with long-term participant engagement.
Objectives: The Heartline Study evaluated the impact of a mobile app-based heart health engagement program with the Irregular Rhythm Notification (IRN) and electrocardiogram features of the Apple Watch on diagnosis, treatment, and outcomes of atrial fibrillation in U.S.

Wearable devices are becoming increasingly prevalent, offering the capability to estimate energy expenditure. Among these devices, the Apple Watch has demonstrated notable results in estimating energy expenditure during physical activity, especially compared to other wearable devices. Its accuracy in determining energy expenditure during electromyostimulation (EMS) training remains unexplored and is investigated in this work.
