Outline of Final Research Achievements

Three-dimensional gait motion analysis was performed for 60 elderly patients with low back pain. The gait load was a long-distance walk. The three-dimensional motion analysis system, the VICON MX system, analyzed spinal and pelvic tilt changes. No dynamic changes in the spine and pelvis coronal planes occurred with walking. On the other hand, continuous walking resulted in a significant progressive anterior tilt of the spine and pelvis in the sagittal plane. In particular, when the spine was measured separately in the thoracic and lumbar spine segments, anterior tilting progressed in the thoracic spine and did not change in the lumbar spine.

Academic Significance and Societal Importance of the Research Achievements

本研究での三次元歩行動作解析では、従来の単純X線でのアライメント計測だけでは評価できない高齢者腰痛症の歩行バランス障害に対して、歩行時にバランスを保とうとするための代償の働きをダイナミックに評価できた。今後,さらに解析症例を蓄積することで、三次元歩行動作解析によって捉えた高齢者腰痛症の個々の代償の違いを考慮して、手術治療などの治療戦略の選択の一助となる可能性がありオーダーメイドの実現が期待される。
