Outline of Final Research Achievements

Objective of this study was to evaluate the muscle volume in the elderly patients with lumbar spinal disorder and the impact of muscle enhancement on the improvement of motor function. Decrease of muscle volume in extremities were seen in low back pain patients with particular reference to lower extremities. Volume of lumbar multifidus muscles has not decrease in sarcopenia patients and even in low back pain patients. One year after lumbar back surgery, muscle volume in extremities significantly decreased with advancing age, while volume of lumbar multifidus muscle decreased under the influence of surgery. Postoperative change in the trunk muscle without affecting low back pain, whereas aging change in the extremity muscles affected. Low back pain patients turned out to be decreased muscle volume in the extremities prior to decrease the trunk muscle volume, thus led to the conclusion that prevention of sarcopenia is important to low back pain.
