What this research studies

If you join, you'll wear a Fitbit that tracks your daily steps while the program sends personalized motivational text messages based on your activity. Messages are automated and tailored to your progress, and your daily step target increases by about 20% every four weeks. The team ran a 12-week randomized pilot where people receiving the texts walked about 1,000 more steps per day than usual care. This R33 phase expands that work to test the remote program's durability and scalability for people with PAH.

Who could benefit from this research

Good fit: Adults diagnosed with pulmonary arterial hypertension who can walk, have a smartphone, and are willing to wear a Fitbit are the ideal candidates.

Not a fit: People who are non-ambulatory, have unstable or advanced cardiac disease that makes activity unsafe, or do not have smartphone access are unlikely to benefit.

Why it matters

Potential benefit: If successful, it could help people with PAH walk more and improve quality of life without requiring inpatient rehabilitation.

How similar studies have performed: A prior pilot of this same mobile text-plus-Fitbit approach increased steps by about 1,000 per day, and other rehabilitation programs have improved six-minute walk distance and quality of life in PAH.
