PC-7 DALING

Location
( P-7 Great Mound DALING – ) 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-7 on 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-7 is 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, lateral 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.
