How many degrees of lateral rotation are in the normal range for shoulder ROM?

The normal range of lateral rotation for the shoulder is typically around 90 degrees. This movement, also known as external rotation, involves rotating the arm away from the body, which is crucial for numerous functional activities, such as reaching behind the back or performing overhead movements.

In assessing shoulder range of motion, it is important for medical examiners to understand these normal ranges to accurately evaluate patients. While variations can occur due to individual differences and factors such as age or injury, 90 degrees is widely recognized as the standard expectation for healthy adults, making this the correct answer. Proper shoulder function and mobility are crucial for overall upper extremity performance, especially in activities that require significant overhead and rotational motion.
