Diaphragmatic dysfunction and alterations of thoracoabdominal motions are common in patients with chronic obstructive pulmonary disease (COPD). Several studies have described an impairment in diaphragmatic mobility of COPD patients compared to age matched control subjects and it has been associated with increase in dyspnea, exercise intolerance and mortality. COPD patients also experiment a higher activity of the accessory breathing muscles, which greatly increases the work of breathing and dyspnea sensation.
Breathing strategies have been considered an important component of pulmonary rehabilitation and refer to a range of techniques, including/which includes the diaphragmatic breathing (DB). The principal aim of DB is to improve the participation of the abdominal motion while reducing the accessory muscles activity. The role of DB as an adjunctive treatment modality in the rehabilitation of COPD patients remains controversial. Despite the conflicting results, improvement of the abdominal motion and a reduction of thoracic excursion, during voluntarily DB, has been described as a common finding of several studies. The investigators hypothesized that a 4-week DBTP could induce higher participation of the diaphragm and this modification would relieve respiratory symptoms and improve exercise tolerance and the HRQoL. Therefore, in this randomized controlled trial the investigators aimed to test the effects of a short-term DBTP on thoracoabdominal motion, pulmonary function, diaphragmatic mobility, dyspnea, HRQoL and exercise tolerance in patients with mild to severe COPD.

|Official Title:||Effects of a Short-term Diaphragmatic Breathing Training Program in COPD Patients: a Randomized Controlled Trial|
|Study Start Date :||June 2008|
|Actual Primary Completion Date :||December 2009|
No Intervention: Control Group
The control group will receive only usual care.
Experimental: Diaphragmatic breathing training
The training group will be submitted to a diaphragmatic breathing training program of 4 weeks.
Other: Diaphragmatic breathing training
The training group will participate in a diaphragmatic breathing program which will consist of three 45-min sessions each week (12 sessions totally). The program training will be individualized and supervised by the same physiotherapist. In each session, the patients will be initially instructed to perform 3 series of 10 maximally inspirations, predominantly with abdominal motion, while reducing upper rib cage motion in a supine position.
