Home-based, remotely monitored pulmonary rehabilitation increases moderate-to-vigorous physical activity in patients with idiopathic pulmonary fibrosis on antifibrotic therapy

In a randomized controlled trial of 29 patients with IPF, a 12-week home-based, remotely monitored exercise program increased daily moderate-to-vigorous physical activity (MVPA) by 28% in the intervention group, while the control group decreased by 35% (p=0.001 for group*time interaction). The intervention group's improvement of 49±19 min/week was nearly double the minimal clinically important difference for IPF. The program was feasible with 100% completion, 92% adherence, and no adverse events.

Child CE, Ho LA, Borders E, Gray T, Olson T, Gordon B, Cai HD, Veras-Tobos E, Traylor K, Babu G, Raghu G, Brown MB · Archives of physical medicine and rehabilitation (2026)

Participants: N/A
Duration: 12-week intervention, with 4-week run-in and 4-week post-intervention follow-up (total 20 weeks)
Intervention: 12-week asynchronously remotely monitored, exercise-focused home pulmonary rehabilitation program with smartphone-linked Bluetooth accelerometer/HR monitor and fingertip pulse oximeter
Outcome: Change from run-in in daily average moderate-to-vigorous physical activity (MVPA) minutes; secondary: 6-minute walk distance, VO2max, quality of life, plasma BNP, exercise oxygen saturation, usability
Effect Size: MVPA change: intervention +28% vs control -35%; absolute change 49±19 min/week (p=0.001)
Population: Patients with idiopathic pulmonary fibrosis on background antifibrotic therapy (n=29 randomized; 15 intervention, 14 control)

Mechanism Graph

Remote monitoring enables personalized exercise prescription and feedback
↓
Asynchronous monitoring allows safe, home-based training without travel burden
↓
Increased physical activity leads to improved exercise tolerance and reduced cardiovascular strain (lower BNP)
↓
Result: Meaningful increase in MVPA and preserved quality of life

Limitations

  • ⚠Small sample size (n=29) limits generalizability
  • ⚠Single-center or regional recruitment may introduce selection bias
  • ⚠No long-term follow-up beyond 4 weeks post-intervention
  • ⚠Control group received monitoring only, not a sham exercise program

Frequently Asked Questions

What is the minimal clinically important difference for MVPA in IPF?▼

The abstract states the intervention improvement (49±19 min/week) was almost double the reported minimal clinically important difference for IPF, but the specific MCID value is not given in the abstract.

How was the home-based pulmonary rehabilitation delivered?▼

Patients received a 12-week exercise-focused program with asynchronous remote monitoring using a smartphone-linked accelerometer/HR monitor and a medical-grade fingertip pulse oximeter. The intervention was entirely home-based.

What were the completion and adherence rates?▼

Program completion was 100% and workout adherence for the intervention group was 92%.

Did the intervention improve quality of life?▼

The abstract notes that within-group effects for the intervention included preserved VO2max and quality of life, but does not report a significant improvement over control.
