The purpose of the study was to analyze the effect of IS and BS on dynamics ventilatory and asymmetry of the chest wall in patients after stroke .
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Incentive Spirometry | Active Comparator | 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 | Active Comparator | 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. |
