COPD患者における呼吸機能，息切れ，QOL，疾患特異的ADL尺度とAMPSとの関連性

Association of AMPS with respiratory function, dyspnea, quality of life, and disease-specific ADL measures in patients with COPD

要旨：本研究の目的は，AMPSを用い在宅COPD患者の動作特性を明らかにすることと，COPD特有の重要なアウトカムとの関連性を明らかにすることである．対象は，在宅酸素療法未導入かつ自宅でAMPSが測定できた13例とした．呼吸機能検査，mMRC息切れスケール，CAT，NRADL，PFSDQ-m，AMPSを測定し，AMPSと各項目測定値との相関を検討した．結果，AMPSの運動技能・プロセス技能ともにCAT，NRADL，PFSDQ-mと相関を認めた．またAMPS運動技能は呼吸機能，mMRC息切れスケールとも相関を認めた．AMPSは既存の疾患特異的ADL尺度と相関を認めたことから，COPD患者のADL能力を反映することが示唆された．

　This study aimed to determine the movement characteristics of COPD patients at home using AMPS and its association with critical COPD-specific outcomes. The subjects were 13 patients who had not yet received home oxygen therapy, and for whom AMPS could be measured at home. Respiratory function tests, mMRC, CAT, NRADL, PFSDQ-m, and AMPS were measured and correlated with AMPS measurements. Results showed that both AMPS motor and process skills correlated with CAT, NRADL, and PFSDQ-m. AMPS motor skills also correlated with respiratory function and mMRC, and AMPS correlated with existing disease-specific ADL scales, suggesting that AMPS reflects the ADL abilities of COPD patients.
