4.7 The Bladder Channel System – Foot taiyang(zu tai yang jing luo)Location
1.5 cun lateral to the posterior midline, on the level of the lower
border of the spinous process of the 10th thoracic vertebra (T10).How to find
In a standing position with the patient’s arms hanging down, the
spinous process of T7 is approximately on the level of the inferior
angle of the scapula (➞3.4.2). From there, count down three
spinous processes to the spinous process of T10. BL-19is located
on the level of the lower border of its spinous process and 1.5 cun
lateral to the midline at the highest point of the paraspinal mus-
culature. Or:Use C7 as a reference point (➞3.4.1). From there,
count down 10 spinous processes to T10 and locate BL-191.5
cun lateral to the lower border of its spinous process. Or:Use
the lumbar spine as a reference point (➞3.4.3).
Located on the same level are ➞Du-7(on the midline), a point
of ➞Ex-B-2(0.5 cun lateral to the midline) and ➞BL-48
(3 cun lateral to the midline).Needling
0.5–1 cun obliquely towards the spine. In clinical practice, this
point is often needled transversely (subcutaneously) towards the
spine. This allows the patient to lie in a supine position during
needle retention (the needles can be secured with tape). Caution:
