Conclusion
• Functional performance measured with a PRO is modestly related to the
amount and intensity of PA.
• Information obtained with a PRO does not provide an insight in the physical
activity level of patients with COPD and can therefore not be used as a
surrogate for objective PA measurement.
• PROactive tool = capturing physical activity by an objective assessment
(activity monitoring) AND symptom experience of the patients (PRO).
