Jiaji jiā jǐ · 夹脊

Location. On the back and low back, 0.5 cun lateral to the lower border of each spinous process from the first thoracic vertebra to the fifth lumbar vertebra; 17 points on each side.

Also called Huatuo Jiaji. The name means beside the spine. This is a group of paired points rather than a single point: one pair beside each of seventeen vertebrae. Each pair lies beside the segment of the spine it belongs to, which is why texts discuss the group in relation to the organs associated with the corresponding segments. Sources differ on the range of the group and some include the cervical vertebrae; this entry follows the common textbook range from T1 to L5.
