Outline of Final Research Achievements |
The aim of this study was to investigate the effects of a manual breathing assist technique (MBAT) on lung volumes, deoxygenation of sternocleidomastoid (SCM) muscle and exercise tolerability in COPD patients. This study was conducted on 15 patients with COPD and 10 non-COPD patients as a control group. The expiratory reserve volume (ERV) significantly decreased (p<0.05), SCM oxy-hemoglobin increased and dyspnea was reduced (p<0.01) in COPD group. Additionally, in 5 of 10 COPD patients, a 6-minute walking distance was extended with MBAT. These results provide evidence that MBAT is a technique to reduce dyspnea in patients with COPD by not requiring excessive use of inspiratory accessory muscles from reducing ERV. Furthermore, it was suggested that MBAT had an immediate effect on exercise tolerability.

Academic Significance and Societal Importance of the Research Achievements |
本研究は,臨床現場でCOPD患者に対して頻用されている呼吸介助の効果について検討した,その結果,予備呼気量の軽減,呼吸補助筋の過活動抑制などによる呼吸困難の軽減といった生理学的反応から科学的根拠を提示でき,さらに運動遂行能力への影響も示唆することができた。このことは,呼吸リハ領域への貢献は大きいと考えており,特に呼吸介助の適応は中等症以上のCOPD患者に対して円滑な運動療法の導入と継続を可能にし,患者の意欲や動機付けの向上が得られ,最終的にQOLの向上にも寄与できると予想される。また,本研究での基礎データが呼吸リハ領域の問題解決に繋がるとともに,エビデンス構築にも貢献できると考える。
