What is the standard flexion degree for the arm when fitting crutches?

The standard degree of flexion for the arm when fitting crutches is 30 degrees. This angle is important for ensuring proper posture and support while using crutches, as it allows for comfort and efficiency in movement. When the arm is positioned at a 30-degree angle at the elbow, it facilitates a natural extension of the forearm, helping to prevent strain on the shoulder and wrist during use. This positioning ensures that the user can effectively transfer weight to the crutches while maintaining balance and mobility. Proper fitting at this angle also contributes to enhanced stability and the ability to navigate different terrains safely.
