Background
Isolated high-velocity and low-amplitude techniques have been shown to be effective in improving joint mobility, supporting the gain of respiratory muscle strength and pulmonary function. However, it is not yet known if osteopathic manipulative therapy can improve these variables.
Objectives
Evaluate the feasibility of a clinical trial and the immediate effects of osteopathic manipulative therapy on thoracoabdominal mobility and its repercussions on respiratory muscle strength and pulmonary function.
Design
This is a preliminary crossover trial.
Methods
Twelve healthy men were allocated to the order of interventions into two groups: osteopathic manipulative therapy group and sham group. Osteopathic manipulative therapy was composed of high-velocity and low-amplitude techniques in cervicothoracic spine transition, thoracic and thoracolumbar spine transition, and myofascial release in cervical fascia and diaphragm. The sham group received simulated treatment. One session was performed at each group. The variables were evaluated pre and post interventions.
Results
There was a significant increase in thoracoabdominal mobility axillary of 7.73 [5.37; 10.08], xiphoid of 4.66 [3.24; 6.07] and abdominal of 4.42 [3.17; 5.68] centimeters in osteopathic manipulative therapy group when compared to sham. We observed an increase of 46.13 [28.06; 64.19] in maximum inspiratory pressure, 29.91 [17.78; 42.04] centimeters of water in maximum expiratory pressure, 0.41 [0.18; 0.65] in forced expiratory volume in the first second and 0.35 [0.05; 0.65] liters in forced vital capacity in the osteopathic manipulative therapy group when compared to the sham group.
Conclusions
Osteopathic manipulative therapy increased thoracoabdominal mobility, respiratory muscle strength and pulmonary function in healthy men.
