Interventions
This is a study that is characterized as a crossover, randomized, double-blind clinical trial with a quantitative approach. The research population will consist of patients with moderate to very sever
clinical stability in the last month prior to the start of the protocol. Individuals will undergo a single application of low-power laser therapy in the ventilatory muscles. As this is a double-blind
