More than two hundred fifty cases of the aged of more than 60 year old were studied about relationship between degree of spinal curvature of thoracic kyphosis and lumbar as well as cervical lordosis and tilting of the sacrum.
Significant co-efficient of co-relations were demonstrated in balanced type of the spinal posture between degree of tilting of superior surface of the sacrum and lumbar lordosis, thoracic kyphosis and lumbar lordosis, as well as thoracic kyphosis and cervical lordosis.
It would be admitted that the curvatures of every part of the spinal column have an influence to each other in balanced type of the posture. In many of severe kyphosis, there have been observed an extension contracture of the cervical and lumbar spine, which showed a limitation of flexion.
Electromyography by surface electrode revealed high action potential from lumbar and/or cervical extensors during standing in case of imbalanced, especially in lumbar and dorsolumbar kyphosis, and gives better informations for treatment.
