  1. POINT LOCATION I Methods for Locating Points

  2. Locating an Acupoint • Anatomical Landmarks and Position • Measuring Methods: • Proportional measurement • Using landmarks • Finger measurement • Convenient measurement

  3. Proportional Cun Measurement Proportional cun: The width and length of various portions of the human body. Divided into definite numbers of equal units, each unit being termed one cun. These are used as the proportional standard in locating points. The length of the cun depends on the build of the individual patient. Adults and Children, Large and Small.

  4. Please note: this proportion measurement is the proportion of the patient! • So “cun” is based on the person you are treating. For human beings this is not a fixed measurement.

  5. Proportional Cun Measurement • The distance between the anterior and posterior hairline is 12cun. • The distance between the glabella (Yintang) and the anterior hairline is 3 cun. • The distance between the angles of the hairline is 9 cun.

  6. ²The distance between the mastoid processes is 9 cun. ² The distance between the posterior hairline and the inferior border of the spinous process of C7 is 3 cun. ²  The distance between the medial borders of the scapulae is 6 cun.

  7. The distance between the nipples is 8 cun. • The distance between the midpoint of the clavicles is 8 cun. • The distance between the tip of the acromion process and the midline of the body is 8 cun. • The distance between the anterior axillary and cubital creases is 9 cun. • The distance between the cubital crease and the wrist creases is 12cun. • The distance between the sternocostal angle and the umbilicus is 8 cun.

  8. ²   The distance between the umbilicus and the pubic symphysis is 5 cun. ²   The distance between the lateral prominence of the greater trochanter (approximately level with the inferior border of the pubic symphysis) and the popliteal crease is 19 cun. ²    The height of the patella is 2 cun.

  9. The distance between the gluteal fold and the knee is 14 cun. • The distance between the popliteal crease and the lateral malleolus is 16 cun. • The distance between the popliteal crease and the medial melleolus is 15 cun.

  10. Finger-Cun Measurement ²   The distance between the ends of the crease of the interphalangeal joints of the middle finger at their widest point is 1cun. ²   The distance between the proximal interphalangeal joint and the tip of the index finger is 2 cun. ²   The width of the interphalangeal joint of the thumb is 1 cun.

  11. ²   The width of the four fingers held close together at the level of the dorsal skin crease of the proximal interphalangeal joint of the middle finger is 3 cun. The width of the index and middle fingers held close together at the level of the dorsal skin crease of the proximal interphalangeal joint of the middle finger is 1.5 cun.

  12. Anatomical Landmarks Fixed Landmarks: • Fixed landmarks are those that would not change with the movement of the body.

  13. Anatomical Landmarks Fixed Landmarks: Hairline and corner of the forehead Nose: Root of the nose, nostril, tip of the nose, wing of the nose) Eye: Canthus, eyeball Ear: Tip of the ear, lobe Zygomatic arch Corner of the mouth, Nasolabial Processes of the cervical vertebrae

  14. Anatomical Landmarks Fixed Landmarks: Scapula Processes of the vertebrae 7th cervical transverse process 4th lumber vertebral process Inferior angle of the scapula

  15. Anatomical Landmarks Moving Landmarks: • Those landmarks are those which appear only when a certain part of the body is kept in a specific position, such as a fold or crease, a depression or prominence formed out of tendon and muscle, or a certain space within a joint. • Examples: SJ 21, SI 19, GB 2, LI 5, LI 11, LI 15, SI 6.

  16. Simple Measurement • DU 20 • SI 6, LU 7, LI 4 • GB 30, GB 31, SP 10
