《黄帝内经·素问·脉解》
所谓腰脊痛不能俯仰的，是因为三月阳气振发，万物荣华繁茂，然尚有余寒，人体应之，故出现腰脊疼痛而不能俯仰的症状。
所谓腰脊痛不可以俛仰者，三月一振，荣华万物，一俛而不仰也。
The so-called unable to bend and raise because of low back pain is because in March, the yang qi is invigorated, all things are flourishing, but there is still some cold, the human body is affected, so there is a symptom of low back pain that cannot be buckled and raised.
