Effects of crossing legs on blood pressure measurement.
The purpose of this study was to determine if blood pressure measurement is affected by the leg crossed at the knee as compared with feet flat on the floor in a well-senior population. Participants (N = 110) either had their blood pressure measured with feet flat first and then crossed or the reverse of this. Results indicate that blood pressure was significantly higher when legs were crossed versus uncrossed. Systolic pressure changed by 5.9 mmHg, from 127.32 to 133.24, whereas diastolic pressure changed by 2.97, from 72.54 to 75.52. There were no significant differences between those who had their blood pressure measured first with their legs crossed versus uncrossed or between those with and without hypertension. Instructing patients to keep feet flat on the floor during blood pressure measurement is an important nursing intervention that can contribute to the accurate measrement, interpretation, and treatment of a patient's health condition.
