| Outline of Final Research Achievements |
We analyzed chest wall motion of patients with cervical spinal cord injury and the effect of mechanical insufflation and exsufflation using a three-dimensional motion analysis system. As a result, in patients with cervical spinal cord injury, paradoxical movement was observed in which the upper thorax volume decreases during inhalation of quiet breathing, and the change in chest wall volume is reduced at head-up position compared with supine position which was mainly caused by the difference of abdominal volume change. Regarding mechanical insufflation, we found that increase in rib cage volume according to insufflation plateaued at certain insufflation pressure or higher.

| Academic Significance and Societal Importance of the Research Achievements |
頸髄損傷者で急性期に特徴的とされる奇異性呼吸は慢性期にも残存していること、頸髄損傷者においては仰臥位の方が頭部挙上位の方が換気量が多いことなど興味深い知見が得られた。高齢社会において、高齢の頸髄損傷者も増加しているが、その呼吸障害の一端が明らかになったことにより、呼吸器合併症の予防などに今回の研究成果や今後得られる知見が生かされることが期待される。
