Diaphragm Activity During Incentive Spirometry and Diaphragmatic Breathing
The objective of the present study is to evaluate diaphragm activity during three breathing exercises: diaphragmatic breathing (DB), flow-oriented (Triflo II)incentive spirometry and volume-oriented (Voldyne) incentive spirometry.
Seventeen healthy subjects will be studied (8 man and 9 woman).

|Official Title:||Diaphragm Mobility During Respiratory Exercises With Incentive Spirometry in Healthy Individuals|
- ultrasound evaluation of the diaphragm mobility [ Time Frame: six - eight months ]
- pulmonary function test [ Time Frame: six - eight months ]
|Study Start Date:||October 2009|
|Study Completion Date:||May 2010|
|Primary Completion Date:||May 2010 (Final data collection date for primary outcome measure)|
Experimental: DB, VI and FV
Device: DB, VI and FI
Two modalities of respiratory exercises based on deep and slow inspirations will be used: DB and IS. During DB, the researcher will place one hand slightly below the lower ribs in the abdominal region of the subject and the subject will be instructed to perform inspirations up to the maximum level of volume avoiding rib cage displacement; this recommendation will also be valid for exercises using incentive spirometers. IS will be executed using two different devices: Triflo II and Voldyne.
