4 Acupuncture Points of the Twelve Primary Channels

Location

In a depression between the acromial extremity of the clavicle

and the junction of the scapular spine and the acromion.

How to find

This point is located on the shoulder, at the angle between the

acromio-clavicular joint and the junction of the scapular spine

and the acromion (➞3.3.1), above the most lateral portion of the

trapezius and supraspinatus muscles. At this point, the tendon of

the supraspinatus delves below the acromion, where it often

causes problems owing to the cramped anatomical structure (for

example, impingement syndrome).
