Summary

Obstructive sleep apnea (OSA) is a chronic, progressive and disabling disease and can affect functional capacity due to the weakness of the respiratory muscles. Therefore, the objective of this study is to evaluate the effect of inspiratory muscle training on functional capacity in patients with OSA. A pilot study will be conducted to calculate the sample. Individuals of both genders, diagnosed with obstructive sleep apnea moderate or severe (measured by polysomnography) will be invited and the data collected in the Sleep Laboratory of the Pronto-Socorro Cardiológico de Pernambuco (PROCAPE), located in Recife- PE- BRAZIL. The study deals with a test-clinical randomized double-blind.The intervention groups held inspiratory muscle training (IMT) and the load is equivalent to 40% of maximal inspiratory pressure (MIP). The evaluations will be performed once a week during twelve weeks. Control groups will be submitted to a simulated training with load less than 10% of MIP (insufficient charge to train the muscles), during the same period as the intervention group. The guidelines for the training and weekly evaluations will be performed by the responsible for the researcher physiotherapist in Cardiopulmonary Physical Therapy Laboratory (LACAP- UFPE). After the training period, the groups will be reassessed by the evaluation tests of functional capacity (ADL- Glittre Test and Ergospirometry), inspiratory muscle strength (manometer) and lung function (spirometry) and then compared. Expected results: The interventional groups will improve their functional capacity.

Conditions

  • Sleep Apnea, Obstructive

Interventions

DEVICE

Powerbreathe

In this intervention we will use an equipment called "powerbreathe classic light". It provides us to choose resistance levels with an adjustable load setting range: 1 to 9 and it's ideal for beginners. In this research we will use it on the intervention group to improve the strength of inspiratory muscle training and evaluate the results in the functional capacity of the subjects with obstructive sleep apnea.
