The aim of this study was to investigate the effect of a 3-week inpatient rehabilitation program (PR) on activity parameter measured by SenseWear®.Methods:Forty patients with COPD, stage III-IV (age: 62±5y; BMI: 26±5kg/m2; FEV1: 36±9%pred.) were included in this prospective trial. PA was measured by SenseWear® Armband in all patients for 3 days at the beginning and at the end of inpatient PR. Additionally, quality of life was requested by SF36 questionnaire and each patient performed a 6-minute walking test (6MWT) (after pretest) pre and post PR.Results:6MWD improved significantly following PR (+39.1 [95% CI, +69 to +8] p=0.01). We observed an increase in mental score of SF36 (+5.10 [95%CI, +9.8 to +0.4] p=0.03). No significant differences between PA parameter pre and post PR were found: total energy expenditure (+35.27±319kcal, p=0.49), steps per day (+293±1419, p=0.20), metabolic rate (-0.01±0.28, p=0.78), duration of PA more than 3fold basic metabolic rate (-4.9±74, p=0.63) were seen. There was no significant difference in PA data between 24 hours calculated as the mean of 3 days compared to the PA data of the first 24 hours of the 3 day measurement.Conclusions:These data show that there are no relevant changes in PA following inpatient PR, although exercise capacity and quality of life are improved. We hypothesize that an inpatient setting predefines the daily amount of PA that is not similar to the activity chosen in daily life at home. We conclude that PA measurement may not be appropriate as an outcome parameter for an inpatient PR. ER -
