Prone Position vs. Supine Position: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 3, 2024
The prone position is lying face down, while the supine position is lying on the back, face up.

Key Differences

The prone position refers to lying flat on the stomach, with the face directed downward. It's a position often used in certain medical procedures and exercises. In contrast, the supine position involves lying flat on the back with the face upward, commonly used in medical examinations and relaxation.
When a person is in the prone position, their back is exposed and accessible, which can be advantageous for procedures like massage or certain surgeries. The supine position, on the other hand, allows easy access to the front of the body, making it suitable for abdominal surgeries or diagnostic tests.
In terms of respiratory function, the prone position can improve oxygenation in certain patients, such as those with acute respiratory distress syndrome. The supine position is generally more comfortable for breathing in healthy individuals but can pose risks for aspiration or respiratory complications in some cases.
For physical therapy and exercises, the prone position is used to strengthen back muscles and improve posture. The supine position is often used for exercises that target the abdominal muscles, chest, or legs.
Both positions have distinct applications in healthcare and fitness, with the prone position focusing on the back and posterior aspects, and the supine position used for accessing the front of the body and facilitating certain types of exercises.
