A total of 128 patients with chronic airflow limitation and exercise tolerance limited by breathlessness took part in a double blind controlled trial to assess the short and long term effects of progressive exercise training and physiotherapy. The results showed that there were no clinically significant objective changes in any group, while subjective improvement measured from questionnaires was significantly greater in both treatment groups compared to the control group (p < 0.001). Patients in the group receiving exercise training combined with physiotherapy showed a significant fall in the level of mood disturbance. All changes demonstrated were maintained once hospital visits had ceased. While measurable change following exercise training may be difficult to establish, significant subjective benefit may be obtained with exercise training and physiotherapy.
