Primary outcomePrimary: Minutes/Day at 12 Weeks — 1.3125000 minutes/day
Summary
Pulmonary rehabilitation clearly increases exercise capacity, but its effect on physical activity in the home and community settings is less clear. It may take a longer time for this increase in physical activity to occur. It has been stated in an editorial that it takes 3 months to train the muscles but 6 months to train the brain. The Investigators will first evaluate the change in physical activity following pulmonary rehabilitation using state-of-the-science motion detectors, then Investigators will follow the trajectory of physical activity over the next several months.

Eligibility Criteria
Inclusion Criteria
- Adults (≥ 40 years) with a primary clinical diagnosis of Chronic Obstructive Pulmonary Disease (COPD)
- A post-bronchodilator forced expiratory volume in one second(FEV1)/forced vital capacity (FVC) < 0.70 from spirometry performed within the preceding 12 months (no specific FEV1 percent-predicted requirement, although we anticipate the FEV1 will average around 45% of predicted, based on previous studies of pulmonary rehabilitation)
- The patient was referred to pulmonary rehabilitation
- The patient is clinically-stable: no exacerbation in preceding 4 weeks
- Modified Medical Research Council (mMRC) dyspnea rating of at least 2 out of 5.
Exclusion Criteria
- Disease severity or co-morbidity that would make the patient be at-risk for participation this study
- A significant movement disorder, such as hemiplegia, etc.
- Inability to read and comprehend the questionnaires, which will be in English
- A history of poor wound healing or chronic skin conditions that might predispose to local problems from wearing the DynaPort. (The DynaPort can be worn outside a thin garment, such as a tee shirt, and is relatively thin, without protruding parts. However, since the device may be worn overnight, and there is a remote risk of pressure problems, this exclusion criterion was added).
