A study by Johns Hopkins researchers shows that arm position during blood pressure screenings can overestimate results, potentially leading to a misdiagnosis of hypertension. The study, published in JAMA Internal Medicine, found that relying on an unsupported arm or placing it on a lap significantly inflates readings. The findings emphasize the importance of following clinical guidelines that recommend firm arm support on a desk for accurate measurements. This research highlights the impact arm position can have on blood pressure readings and stresses the need for healthcare providers and patients to adhere to best practices in monitoring blood pressure.
