CF-CATS: An uncontrolled feasibility study of using tai chi for adults with cystic fibrosis

IntroductionCystic fibrosis (CF) can adversely affect quality of life. This study on tai chi (TC) for cystic fibrosis (CF) was an uncontrolled pilot trial assessing the feasibility of a future controlled trial.MethodsAdults with CF, recruited from the Royal Brompton Hospital, UK, were taught weekly TC (based on the “eternal spring” set) for 5 weeks in participants' homes. They continued with DVD and home practice for 5 further weeks. Cystic fibrosis questionnaire revised (CFQ-R), hospital anxiety and depression scale and brief pain inventory were completed at baseline, 5 and 10 weeks. Healthcare use, TC practice, symptoms, and wellbeing were recorded weekly, medical data at baseline and 10 weeks. Data compared before and after TC. Two online focus groups explored experiences and feedback on research methods.ResultsEleven patients were recruited, mean age 38, five working/studying, baseline predicted FEV1 between 26% and 74%. Treatment constraints and respiratory symptoms (CFQ-R) significantly improved (mean decrease 27.78 (p = 0.023) and 11.90 (p = 0.05) respectively). Numerous health fluctuations were recorded.TC was perceived as a “powerful tool”, relaxing and calming. Challenges to TC practice included hospitalisation, poor health, other treatments and forgetting movements. The DVD was helpful. No problems participating were reported.ConclusionTC may reduce CF treatment impact, improve respiratory symptoms, self-efficacy and sleep. Participants' poor and fluctuating health and the small sample potentially affected results. Such research appears appropriate and feasible. Suggestions for a future trial include measurements of quality of life, dypsnoea, self-efficacy, coping, sleep, exercise levels, longer follow up and frequent assessment.
