What is the normal range of motion for shoulder abduction?

The normal range of motion for shoulder abduction is between 160 to 180 degrees. This range allows the arm to be raised away from the body, which involves primarily the movement of the deltoid muscle, as well as assistance from the supraspinatus and other muscles around the shoulder joint. The significance of this range lies in its functional implications for overhead activities, daily movements, and overall upper body mobility. When individuals can achieve this level of abduction, it indicates healthy joint mechanics and muscle strength, which are crucial for performing various exercises and daily tasks effectively. Understanding this range helps trainers assess their clients’ mobility and functionality, guiding appropriate training and rehabilitation programs.
