Cautions & contraindications

No deep needling

Location

A set of 34 paired points on the back, 0.5 cun lateral to the lower border of each spinous process from T1 to L5.

How to locate: With the patient prone, choose the spinal segments to be treated, using the lower angle of the scapula (T7) or the line joining the iliac crests (L4) to count vertebrae; each point is 0.5 cun lateral to the lower border of the spinous process, over the facet joint.

Distances are in cun, a proportional unit — how to measure.

3D view

3D view not available for this point: its position on the 3D model couldn't be checked against its location text, so it is not shown. The 2D maps above show it.

Needling

No deep needling

Depth: 0.5–1.0 cun

Angle: Perpendicular, or angled slightly toward the spine

⚠ Cautions: In the thoracic region, angle toward the spine and observe the depth limit — deep lateral needling risks pneumothorax.

Functions

Regulates the qi of the corresponding spinal segment and its organ
Relieves pain and stiffness of the spine
Treats the internal organs segmentally

Indications

Spinal pain and stiffness at any levelsegmental treatment of internal organ disease — the thoracic points for chest and upper abdomen, the lumbar for lower abdomen and legsintercostal neuralgia and shinglesnumbness and weakness of the limbsparalysis after spinal injury

Clinical Notes

Not one point but a paired series along the whole spine, attributed to the physician Hua Tuo. Because each pair sits over a segmental nerve root, they give a precise anatomical route to both the spine and the viscera; they are the backbone of orthopaedic and neurological acupuncture.
