Clinical notes

Yanglao is a crucial distal point for acute and chronic pain of the entire arm, from the shoulder to the wrist. Its name, 'Nourishing the Aged', highlights its traditional use for improving vision, particularly in cases of age-related decline. The specific method of locating the point by rotating the forearm is key to accessing the cleft where the point resides and is a classic example of a dynamic point location.
