Outline of Final Research Achievements |
It is difficult to determine the cause of low back pain, and in 80% of cases, the cause cannot be identified. In the case of lifting people for nursing care, the movements of each worker are different, and the lumbar strain, which is the cause of back pain, differs from person to person. In this study, we constructed a new non-invasive internal load measurement system focusing on the lumbar region in order to respond to individual needs. Based on this system, we evaluated the relationship between lumbar load and psychological factors using a pelvic belt. We confirmed the correlation between the lumbar load value and the burden. In addition, we conducted a questionnaire survey on nursing care work and analyzed the relationship between low back pain factors and work. In the future, the combination of the questionnaire and the measurement of the lumbar load value will lead to the clarification of the low back pain factor.

Academic Significance and Societal Importance of the Research Achievements |
本研究では,人体の中でも複雑な動作を行える腰部への研究として非侵襲的内部負担計測システムの構築をした.腰部動作に関する研究は多く行われてきたが,回旋・側屈を含む複雑な腰部動作中の腰仙椎アライメントに対して表皮上から各椎体姿勢を推定するアルゴリズムを構築した.人によって腰痛要因は異なるため,作業と腰部負担の関係性から腰痛要因の解明に利用できるウェラブルな腰部負担計測システムを構築した.また,腰痛に対する研究として腰部補助器具の開発は進んでいるが,アシスト器具の定量的評価に構築したシステムを利用した.
