A study testing Breath-Stacking in people with Muscle Weakness, run by Federal University of Health Science of Porto Alegre at 1 site in Brazil.
Trial summary
In several diseases in which muscle weakness is a determining factor for morbidity and mortality, inspiratory muscle training has been shown to be useful in improving the function of ventilatory muscles, delaying or minimizing the development of complications due to the reduction of inspiratory muscle strength.

About this study
Official title: Breath-Stacking and Ventilatory Muscle Strength
In several diseases in which muscle weakness is a determining factor for morbidity and mortality, inspiratory muscle training has been shown to be useful in improving the function of ventilatory muscles, delaying or minimizing the development of complications due to the reduction of inspiratory muscle strength.
The breath-stacking technique emerges as an easily applicable alternative, and it can be used in poorly collaborative patients. The technique described in the literature aims to increase pulmonary volumes.

This gain occurs with the coupling of a silicone mask on the patient's face, a unidirectional valve and with the expiratory branch occluded. Thus, inspirations occur sequentially in this medium, generating pulmonary hyperinflation and increasing the contractility power of the expiratory muscles, which are fundamental for coughing. This hyperinflation also improves the peripheral air distribution in the lungs by increasing intrathoracic pressure.
The objective of this study is to evaluate the effect of the breath-stacking (BS) technique on the ventilatory muscle strength of young and healthy individuals.
Read the detailed description
Initially, participants will be submitted to a learning session on the evaluation of ventilatory muscle strength and the breath-stacking technique. Between 24-72 hours after the learning, the evaluation of the muscular muscular strength will be performed through the maximal inspiratory pressure (MIP) and the maximum expiratory pressure (MEP). PI max will be measured from a maximum expiration; While PE max will be measured from a maximum inspiration, using a digital manovacuometer (MVD 300®)

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Breath-StackingOther
Participants will be seated, with their elbows resting on the table, holding the face mask attached to a T-tube and a one-way valve. They will be instructed to inspire and force the expiration inside the mask. The training will be conducted three times a week for a period of four weeks, totaling twelve sessions. The breath-stacking application protocol will consist of three three-minute series, with a three-minute recovery interval between each series, obtaining a total time of fifteen minutes in each session.
