Pedometers and Walking Tests for Pulmonary Hypertension Patients

Not Applicable

Conditions
Hypertension, Pulmonary
Interventions
Device: Pedometer
Other: 6 minute walking test
Registration Number
NCT03810482
Lead Sponsor
University Hospital, Montpellier
Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures
NameTimeMethod
The patient's discordance category as precisely defined here:74 days

Linear regression is performed for the distance walked during an initial 6 minute walking test (6MWT) and the average distance walked per day according to the pedometer intervention. The residuals from this regression will determine categories:

Category 1 (pedometer high): the 25% of subjects not in category 2 and with higher values for pedometer data

Category 2 (concordance): the 50% of included subjects with the smallest residuals in terms of absolute value.

Category 3 (6MWT high): the 25% of subjects not in category 2 and with higher values for 6MWT data

Secondary Outcome Measures
NameTimeMethod
Coping with Health Injuries and Problems ScaleMonth 3

This questionnaire assesses how the patient responds to health injuries and problems with 32 questions. For each question 5 levels of response are possible from 1 (not at all) to 5 (always).

Multidimensional Fatigue Inventory (MFI)-20 questionnaireMonth 3

This questionnaire assesses the severity of the patient fatigue through 20 questions. For each question, 4 levels of response are possible : from "not at all" to "completely".

Health related quality of life questionnaire (the Medical Outcome Study - Short Form (SF36))Month 3

This scale evaluates social, emotional and physical health of the patient through 11 questions.

Hospital Anxiety and Depression (HAD) scaleMonth 3

It is a questionnaire which detects if the patient is anxious or depressed through 14 questions.

State-Trait Anxiety Inventory (STAI) questionnaireMonth 3

The State-Trait Anxiety Inventory is a 20 question-scale. For each question 4 levels of response are possible from 1 (never) to 4 (always).
