Evaluation of the forced expiration technique as an adjunct to postural drainage in treatment of cystic fibrosis.

Sixteen patients with cystic fibrosis were treated with conventional physiotherapy aided by 
an assistant. The results were compared with those produced by physiotherapy 
using the forced expiration technique cleared more sputum in less time 
than conventional physiotherapy. A sputum in less time than conventional physiotherapy. 
A second study showed that an assistant did not further improve 
the results obtained by the patient performing the forced expiration technique 
himself. These findings mean that patients with cystic fibrosis who have 
had to rely on the help of others for their home 
treatment may now perform more effective treatment without help. The forced 
expiration technique might also be helpful for patients with chronic bronchitis, 
asthma, or bronchiectasis.
