The primary objective of this Non Interventional Study is to measure changes in physical functioning, a surrogate for physical activity and exercise capacity, in COPD patients on treatment with Spiolto�� Respimat�� in routine daily treatment after approximately 6 weeks. A secondary objective is to evaluate the patient's general condition (physician's evaluation) from Visit 1 (baseline visit at the start of the study) to Visit 2 (final visit at the end of the study, approx. 6 weeks after Visit 1), as well as patient satisfaction with Spiolto�� Respimat�� at Visit 2.
