Résumé
The Back-Shu points of the five Zang-organs are a group of points where qi and blood pour into the back and lumbar regions. Acupuncture at these points has a wide indication scope. However, it’s reported that internal organs were punctured in some cases because of improper control of needling depth, angle, and intensity during acupuncture. We used perpendicular needling instead of conventional oblique needling during the acupuncture of the Back-Shu points of the five Zang-organs. We found that when patients were completely relaxed, acupoints were correctly selected, the needling depth, the way of holding the needle, and inserting methods were well controlled, perpendicular needling of the Back-Shu points of the five Zang-organs can produce stronger needling sensation, and it’s easier to operate, safer, and more effective compared to oblique needling.
