| Outline of Final Research Achievements |
Decreases in exercise capacity and physical activity significantly affect quality of life and prognosis of patients with chronic respiratory diseases such as COPD and interstitial pneumonia. However, a cardio-pulmonary exercise test using exhaled gas analysis requires substantial efforts of the patients. In this study we demonstrated that tidal volumes, respiratory rates, and mimute volumes can be monitored during an increasing exercise load test with an ergometer using Kinect sensor without contact with the patient. Anaerobic metabolic thresholds were also estimated by this system in healthy subjects and COPD patients, which will bring valuable information for the exercise prescription. Respiratory patterns including changes in tidal volumes and respiratory rates during an increasing exercise load test were different between patients with COPD and interstitial pneumonia through the analysis of respiratory movements of the chest using Kinect sensor.

| Academic Significance and Societal Importance of the Research Achievements |
呼吸器疾患患者では、労作時の息切れがADLとQOLの低下の主因となっている。労作時の息切れを正確に評価し、改善するためには、簡便かつ正確に呼吸運動を計測することが重要であるが、６分間歩行試験では歩行距離とSpO2低下を評価するのみであり、心肺運動負荷試験では、密着性の高いマスクの装着が患者の負担となっていた。Kinect sensorでは体幹部に投射した赤外線が反射して戻る際のtime of flightの計測により、運動中の換気量と呼吸数を測定可能であり、患者に全く負担のないシステムである。今後、呼吸器疾患患者のリハビリテーションのみならず、日常での活動性維持のためのツールとして期待される。
