Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

All volunteers were undergone to two types of pulmonary expansion therapy (PET) techniques: volume incentive spirometry (VIS) and BS.

Procedures involved two distinct phases: assessment and intervention. In the first day was performed assessment of the participants to obtain the following data: anamnesis, initial evaluation using the Ashwouth Scale, Barthel Index and Mini Mental State Examination, anthropometric data and pulmonary function using spirometry and respiratory muscle pressures.

Intervention phase was performed in two different days, each day for only one PET techniques (VIS or BS), with a minimal wash-out period of one day according to the randomization sequence. Optoelectronic Pletysmography (OEP) was recorded during quite breathing at rest and during the execution of five maneuvers form each PET technique tested.

Study Groups

Incentive Spirometry

The Incentive Spirometry was characterized by the use of the incentive spirometer volume, in which volunteer used a nasal clip and was instructed to inhale slowly and deeply through the mouthpiece of the equipment from functional residual capacity to total lung capacity.

The Incentive Spirometry was characterized by the use of the incentive spirometer volume, in which volunteer used a nasal clip and was instructed to inhale slowly and deeply through the mouthpiece of the equipment from functional residual capacity to total lung capacity.

Breath Stacking

Breath Stacking A mask was used with two one-way valves (inspiratory limb and expiratory limb), which was coupled to the patient's face allowing only inspiration, while the expiratory branch remained occluded for the individual only perform successive inspiratory efforts.
