만성 폐색성 폐질환자를 위한 호흡 재활 중재가 운동능력 및 내구성, 일반적 건강상태에 미치는 효과에 대한 메타분석

초록

Purpose: This study was conducted to combine the effects of pulmonary rehabilitation program (PRP) on exercise capacity/tolerance and general health status of COPD patients based on the primary research results which examined the effects of PRP. Methods: Seventeen studies were selected by the sampling criteria estabilished to include the studies that reported enough statistics necessary to conduct meta-analysis. Results: According to the study results, the most effective indicators for exercise capacity/tolerance were exercise time (such as cycling time or treadmill walking time) and ground walking distance within given time (6 minutes or 12 minutes), whereas effects on such indicators as VE and VO2 were not statistically significant. PRP induced significant effect on patients' general health status frequently measured by physical, psychoemotional, and wholistic indicators, especially, the enhancement on psychoemotional demension resulted from PRP was more prominent than that of the other demensions. From the results, it was noted that the place that PRP was given and the contents of PRP exercised their influence on the outcome variables. Which body part was trained was also one of the important factors that influence on the pateints' perception of dyspnea during execise as well as on exercise capacity/tolerance. Conclusion: PRP including exercise training significantly improved the exercise capacity and general health status of COPD patients.
