Supraspinal ligament injury ,The supraspinal ligament (supraspinous ligament) is a strong fibrous cord, which connects together the apices of the spinous processes from the seventh cervical vertebra to the sacrum; at the points of attachment to the tips of the spinous processes fibrocartilage is developed in the ligament.The supraspinous ligament (SSL) runs along the middle of the back attaching to the dorsal spinous processes of the vertebrae. It may be damaged as the result of direct trauma. But in most cases, injury is thought to be due to overstretching of the ligament fibres, particularly in jumping horses.

To compare the efficacy difference on the treatment of supraspinal ligament injury in deficiency syndrome between only-puncturing at Dazhong (KI 4) and routine acupuncture therapy and then explore an optimum process,Chinese Qin YG etc have done a research about this.Their hundred and twenty-six cases were randomly divided into a Dazhong group (63 cases) and a routine acupuncture group (63 cases). Based on the same treatment including TDP irradiation, cupping at Shenshu (BL 23), Dachangshu (BL 25), Mingmen (GV 4), Yaoyangguan (GV 3) and Ashi points, the patients in the Dazhong group received only-puncturing Dazhong (KI 4) with respiratory reinforcing method once daily or every other day, three times of which made a course of the treatment, with on interval of one day or without between different courses. For the routine acupuncture group, the same reinforcing method was applied at shenshu (BL 23) pointect, and the other requirements such as courses were also the same.

They found that only-puncturing Dazhong (KI 4) method combined with cupping and TDP irradiation are simple and effective for supraspinal ligament injury in deficiency syndrome.
