Short-term effect of osteopathic manual techniques (OMT) on respiratory function in healthy individuals

BackgroundRespiratory system diseases are some of the most common pathologies worldwide. Although osteopathic manual therapy (OMT) is used predominantly to treat other pathologies, certain OMT techniques have been shown to improve patients' respiratory function.ObjectivesThe aim of this study was to assess the influence of osteopathic techniques on breathing.MethodsTests were performed with the use of a spirometer and the results were expressed as Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), and Peak Expiratory Flow (PEF). Thirty healthy males and females between the age of 18 and 50 took part in the research. Fifteen individuals were randomly assigned to the experimental group and fifteen persons were assigned to the placebo group. The participants from the experimental group were treated with such osteopathic techniques aimed at the pulmonary system as the thoracic thrust (manipulations of vertebral joints and ribs), the sternal pump technique and stretching of the diaphragm. The placebo group was treated with soft tissue therapy (STT) techniques for the masseter muscle.ResultsThe described set of osteopathic techniques exerts an influence on PEF in healthy individuals; however, it does not affect FVC and FEV1.ConclusionOsteopathic techniques do not seem to improve lung health, as reflected in FEV1 and FVC, but they improve the respiratory function aspects reflected by PEF in the participants without any history of lung disease.
