Outline of Final Research Achievements

The purpose of the present study was to objectively and quantitatively approve the relation between gait functions and neural activities in the cerebral motor area before and after cervical decompressive surgery for patients with myelopathy of cervical spondylosis cervical ossification of the posterior longitudinal ligament and using a tri-axial accelerometer. We could be only performed the gait assessment before and after the surgery in the patients. On the other hand, we could also perform the following related works: 1) evaluation of gait symmetry using a tri-axial accelerometer in patients with lumbar spinal canal stenosis, and 2) objective improvement of gait disturbance after operation for patients with intramedullary tumor of spine. Finally, this study demonstrated that a tri-axial accelerometer is useful for postoperative gait evaluation of spine and spinal cord disease.

Academic Significance and Societal Importance of the Research Achievements

頸椎症もしくは頸椎後縦靱帯骨化症による圧迫性脊髄症に対して手術を行い、術後の歩行機能の改善について歩行分析計を用いて歩行測定を行った。圧迫性脊髄症に対する手術は、歩行改善をもたらすことを客観的に評価ができた。また、腰部脊柱管狭窄症では、術後の歩行改善について、歩行測定を行うことによって客観的に評価できた。これらのデータは、圧迫性脊髄症や腰部脊柱管狭窄症の手術が有用であると説明ができる。また、これらのデータを術後の患者さんに説明することにより、手術の満足度も上がることが期待される。
