Abstract

Background And Objective: IPF is a chronic progressive lung disease in which PR provides benefit for patients. PD, a TCM PR programme, has known effectiveness in COPD, but its utility in IPF is unknown. We investigated its effectiveness and safety in patients with IPF.

Methods: A 6-month randomized controlled trial (RCT) was conducted in three Chinese clinics. Ninety-six participants diagnosed with IPF were randomly assigned to one of the three groups: the PD group received a PD programme two times a day, 5 days/week for 2 months, and the exercise group exercised via a stationary cycle ergometer, 30 min/day, 5 days/week for 2 months. Volunteers in the control group were advised to maintain their usual activities. Primary outcomes were changes from baseline in the 6MWD and HRQoL score on the SGRQ-I at 1 and 2 months (at the end of the intervention) and at 6 months (4 months after the intervention). Secondary outcomes measures included FVC, DL (% predicted) and the changes in mMRC.

Results: The 6MWD was increased in the PD group compared to exercise and control groups. 6MWD increased by 60.44 m in the PD group, 32.16 m in the exercise group and 12.42 m in controls after the 2 months of rehabilitation programme. The between-group differences in the change from baseline were 28.78 m (95% CI: 0.54 to 56.01; P = 0.044) and 48.02 m (95% CI: 23.04 to 73.00; P < 0.001) at 2 months, and 25.61 m (95% CI: -0.67 to 51.89; P = 0.058) and 50.93 m (95% CI: 25.47 to 76.40; P < 0.001) at 6 months, respectively, including a difference exceeding the MCID. There was no significant change in the SGRQ-I score, the mMRC dyspnoea score, FVC and DL (% predicted) in either the PD or exercise groups.

Conclusion: Two months after the intervention, a clinically meaningful difference in 6MWD was observed favouring the PD programme. The PD programme is safe and effective as a rehabilitation intervention designed to increase exercise tolerance and is an appropriate substitute for PR.
