Name and classical tradition
Yaotongdian, 腰痛点, is the “low back pain point,” a name that is itself an indication: 腰痛, pain in the waist; 点 (點), point. There are two points on the dorsum of each hand, between the metacarpals, far from the area they treat.
The name, with the modern word 点 in place of 穴, gives away a 20th-century point, and it does not appear in any of the classical works we were able to check. Its logic is that of the distal point, which is very old: the same principle that leads us to treat the back through BL40, Weizhong, in the song of the four major points.
