Meridian Sinews and Sagittal Spinal Balance

Sagittal spinal balance means standing postural balance at sagittal plane. Postural imbalance with displacement of the patient's center of gravity can cause chronic back pain and ambulatory difficulty. The sagittal spinal balance is determined based on the deviation of the C7 plumb line, originating at the middle of the C7 vertebral body, from the posterior superior endplate of S1. The line is called as sagittal vertical axis (SVA). In the traditional Korean medicine, the meridian sinews, which are the most superficial pathways of the meridian system, associated with movement, muscle balance and defense. They too are separate from the main meridians, though they intersect the main meridians. Some creative and pioneer researchers in Korea thought that the anatomy trains, which suggested by Myers is a concept familiar to the meridian sinews. A reciprocal relationship between the superficial back line and the superficial front line used to be compared to the rigging of a sailboat. Therefore, We suggest that spine may be compared to a mast of the sailboat and that the sagittal spinal balance can be maintained with systemic reciprocal interacts between the front line muscles and the back.
