Which active range of motion exercise improves mobility of the distal radioulnar joint?

The exercise that most effectively improves mobility of the distal radioulnar joint is forearm pronation and supination. This joint, located at the distal end of the radius and the ulna, allows for the rotation of the forearm. When performing pronation, the palms move to face downwards, while in supination, the palms face upwards. These movements are essential for various daily functions and sports activities, enabling actions such as turning a doorknob or using utensils.

By specifically targeting pronation and supination, the exercise helps to enhance the mobility of the distal radioulnar joint, ensuring that the connective structures around it remain flexible and strong. This joint plays a crucial role in hand positioning and functional tasks, making the improvement of its mobility vital for overall forearm function.
