4.9 The Pericardium Channel System – Hand jueyin(shou jue yin jing luo)

Location

On the anterior aspect of the wrist joint space (‘most distal wrist

crease’), between the tendons of the palmaris longus and flexor

carpi radialis muscles.

How to find

As the location of the wrist crease varies, the wrist joint space

is a more reliable reference point (➞3.3.3). By moving the

patient’s hand in a relaxed way, it can easily be palpated. Locate

P-7on this level between the two tendons, which become more

pronounced when the fingertips are pressed together. If only

one tendon is visible, this will be the tendon of the flexor carpi

radialis muscle. P-7is located on its ulnar aspect.

Located on the same level are ➞HE-7(on the ulnar aspect of

the wrist joint, radial to the tendon of the flexor carpi ulnaris

muscle) and ➞LU-9(on the radial aspect of the wrist joint, lat-

eral to the radial artery.

Needling

Vertically 0.3–0.5 cun, for carpal tunnel syndrome also 0.5–1

cun obliquely in a lateral direction along the tunnel. Caution:

The median nerve is located directly under this point, thus

needling can cause a significant electric sensation; in this case,

no further needle manipulation to avoid possible injury.
