Pedometers and Walking Tests for Pulmonary Hypertension Patients
Pedometers and Walking Tests for Pulmonary Hypertension Patients
Concordance between walking tests and pedometer data may seem like a logical outcome for
 pulmonary hypertension (PH) patients. However, many individuals have discordant results:
 results much worse or better during an in-hospital walking test as compared to real life
 activity.

 The primary objective of this study is: to determine variables associated with discordance
 between the distance walked during an in-hospital 6-minute walking test (6MWT) and the
 average distance travelled per day (observed over a period of 28 days (2 × 14 days) using a
 pedometer) among PH patients.
Secondarily, the discordance between 6MWT results versus total pedometer recorded distance
 and versus maximum daily pedometer-recorded distance will be similarly studied. The aim of
 the study is also to search for variables associated with progression free survival. The
 relationships between pedometer data and self-reported dyspnea variation will be studied.
 Factorial analysis may be used to study the overall view of variable correlations and patient
 similarity/dissimilarity.
