Introduction
The measurement of blood pressure in the legs is generally performed using devices such as mercury sphygmomanometers or electronic blood pressure monitors. The normal range is typically defined as systolic pressure between 110–159 mmHg and diastolic pressure between 90–119 mmHg. If abnormal results are obtained, prompt medical consultation is recommended, and targeted management should be conducted under a physician's guidance.
Measurement of leg blood pressure is generally performed using devices such as mercury sphygmomanometers or electronic blood pressure monitors, following these specific steps:
The subject should lie flat or in a prone position, empty the bladder, and remain calm. Use a dedicated mercury sphygmomanometer or electronic blood pressure monitor along with an appropriate cuff. Place the lower edge of the cuff approximately 3–5 cm above the popliteal fossa on the thigh near the femoral artery, or about 3–4 cm above the medial malleolus near the ankle on the lower calf. Inflate the cuff to an appropriate pressure and then slowly release the air while listening for the Korotkoff sounds to determine systolic and diastolic blood pressure. During the measurement, ensure the cuff is properly secured—not too tight or too loose—and perform the procedure under professional guidance to ensure accuracy.
The normal range for leg blood pressure is generally between 110–159 mmHg for systolic pressure and 90–119 mmHg for diastolic pressure. Leg blood pressure is typically 20–40 mmHg higher than upper limb blood pressure. If abnormal results occur, timely medical consultation is advised, and targeted interventions should be conducted under a physician's guidance.
In addition, maintaining a healthy lifestyle in daily life, improving dietary habits, engaging in appropriate physical exercise, enhancing physical fitness, and reducing the risk of disease are all recommended.
