Exercise is commonly used as a substitute for traditional airway clearance techniques by adults with cystic fibrosis in Australia: a survey.

QUESTIONS

What airway clearance techniques and exercise regimens are used by adults with cystic fibrosis (CF) in Australia when well or unwell? What proportion of these adults believe that exercise can be used as a substitute for traditional airway clearance techniques, and how have they come to this belief? What type of exercise is used as a substitute for traditional airway clearance techniques?

DESIGN

Cross-sectional survey at 13 CF centres in Australia, using a purpose-designed questionnaire.

PARTICIPANTS

Six hundred and ninety-two adults with CF completed the questionnaire.

OUTCOME MEASURES

The questionnaire included questions about: the participants' current use of traditional airway clearance techniques and exercise, when well and unwell; and beliefs regarding the use of exercise as a substitute for traditional airway clearance techniques.

RESULTS

Coughing, huffing and positive expiratory pressure were the most commonly used airway clearance techniques. Walking, jogging and lifting weights were the most commonly used forms of exercise. Overall, 43% of participants believed that exercise could be used as a substitute for traditional airway clearance techniques, with 44% having substituted exercise for traditional airway clearance techniques in the previous 3 months. Personal experience was the most commonly reported factor influencing participants' beliefs about the use of exercise as a substitute for traditional airway clearance techniques.

CONCLUSION

Exercise is commonly used as a substitute for traditional airway clearance techniques. Physiotherapists should advise patients that whilst there is some research suggesting a possible mechanism for exercise as a form of airway clearance, there are currently no medium-term to long-term data supporting exercise as a stand-alone form of airway clearance. These results suggest that future research to investigate the clinical effectiveness of exercise as a substitute for traditional airway clearance techniques should be a priority.
