There are oh-so-many ways that the low back and knees are connected. One that has been catching my attention of late is that people who complain of chronic low back pain invariably have grainy, mealy, lumpy, unhealthy soft tissue on the popliteal fossa (backs of the knees). In the middle of the popliteal folds (transverse crease of popliteal fossa, to be precise) is Bladder 40 (UB40, Wei Zhong), a potent acupoint for low back pain. How did the ancient Chinese physicians make this connection? There are many theories and beliefs about how acupuncture came to be. But I wonder if perhaps some physicians, who were more focused on manual modalities and the cadaver studies done at the time, noticed this difference in the tissues and that perhaps this contributed to the discovery of the acupoint.

Tissues reflect the health of the structures with which they are related. Often these are contiguous (next-door or adjacent) structures, but sometimes these structures are related through their fascial connections (like the low back & knees). It is through these fascial connections that tissues can, in turn, influence the health of other organs and structures in the body. It goes both ways. So keeping the tissues healthy through hydration, nutrition, massage, manual therapies, skin brushing, etc is important to overall health of the internal organs.
