Physical activity in daily life is increasingly used as an outcome measure in chronic respiratory disease.1 Valid and user-friendly instruments are needed to quantify daily activity.1 2 The DynaPort activity monitor (McRoberts, The Hague, The Netherlands) has been validated and used in patients with chronic obstructive pulmonary disease (COPD).3 4 The device is, however, technically difficult to handle and, due to its size (12.5×9.5×3 cm, 375 g), it is always noticeable. We therefore validated two smaller activity monitors in a sample of 10 patients with COPD (mean (SD) forced expiratory volume in 1 s 49 (16)% predicted; mean (SD) age 65 (8) years) and 10 healthy elderly volunteers (mean (SD) age 65 (9) years). Detailed characteristics of the study subjects are summarised in table 1 in the online supplement.

All patients simultaneously wore the DynaPort, the SenseWear Pro (SenseWear, Body Media, Pittsburgh, USA) activity monitor (8.5×5.0×1.5 cm, 85 g), …
