The area of the body that the Chinese call the Kua extends from the inguinal ligament through the inside of the pelvis to the top of the hip bones. Included within the Kua are the left and right channels of energy, the pelvis, including the hip joint, the sacrum and first few lumbar vertebrae, the ilopsoas muscle group, the adductor muscles, the pelvic diaphragms (the health of which is essential to sexual vitality), the lower intestine and the rectum.
The muscles of the kua connect the legs to the spine, the iliopsoas connects the lumbar vertebrae to the pelvis and femur (Thigh bone), and the adductors connect the pelvis to femur. The springiness of the spine and legs is partially determined by the elasticity of the iliopsoas muscles. Many lower back problems are caused by stiffness, spasm or trauma in these muscles.
At the inguinal groove, the largest collection of lymph nodes in the body can be found. Lymph is a critical component of the bodys immune response system. Unlike blood, which is moved by the heart and vascular system, lymph is basically moved by muscular contractions. Nature is very wise, every time we walk or move our legs and arms, large lymph collectors are activated, thus moving our lymph. Chinese Qi Gong exercise and Tai Chi simply increase this natural phenomenon, there by strengthening a very important component of the immune system. Increasing the movement of the internal element of the Kua is one of the most significant and unique contributions to health of all the Chinese enhancing body practices.
