Abstract:

Hypothesis: Osteopathic manipulative medicine (OMM) applied to the thoracic cage and diaphragm has empirically been used to improve chest excursion and breathing capability. However, research has been sparse in showing quantifiable measurements of therapeutic effect. The authors believe that using pulmonary function testing quantifiable measurements of therapeutic effect can be shown. This study investigates the effects of selected OMM techniques on the respiratory system using pulmonary function tests (PFTs). Methods: Study subjects were involved in a randomized control, pretest, posttest crossover design requiring one sham visit and one treatment visit. During each visit, PFTs were performed by a blinded technician before and after either treatment or sham. The treatment visit included treatment with 5 OMM techniques: seated thoracic spine articulatory technique, seated rib articulatory technique, anterior abdominal diaphragm doming, thoracic outlet release via balanced ligamentous tension (BLT), and twelfth rib release via BLT. The PFT values measured were forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC, peak expiratory flow, and forced expiratory flow 25% to 75%. Results: Eighty subjects met the inclusion criteria of the study. Twelve subjects were lost to follow up. For all PFT values measured, pretreatment was not significantly different from post treatment. Effect size was small ranging from 0.065 to 0.264. For all PFT values, posttreatment was not significantly different from post-sham. Effect size was small ranging from 0.008 to 0.202. Conclusion: The 5 OMM techniques applied to healthy subjects did not result in an observable change in PFTs. This is an expected finding as the subjects had no known pathology. Yet, the techniques may offer some measurable change in PFTs of patients with respiratory disease. This study provides a basis for the exploration of the effect of OMM techniques on the PFTs of patients with known pathology. If there is an effect, the conclusions would be more powerful given that changes were non-existent in the healthy cohort. The authors intend to explore the new hypothesis that this study has generated: OMM techniques applied to the thoracic cage and diaphragm of asthmatics provide a therapeutic effect that can be measured as changes in PFTs. Should this hypothesis prove true, it would provide a rationale for the use of OMM techniques as an adjunct to current asthma management.
