Summary

Determining the effects of an intervention plan on the diaphragm related to the center of gravity and range of motion in the lumbar spine (static and dynamic) in healthy individuals is an area that lacks evidence and proper studies. Has such, the investigators consider this a interesting topic to study, therefore it is intended to improve the knowledge on this area.

Detailed description

All diaphragmatic activity is controlled by metabolic mechanisms and emotional states which may cause restrictions that might be related to disorders in the lower back. The diaphragm and the lumbar segment of the spine are connected through the diaphgramathic pillars that connect the central tendon and the vertebrae of L2 (left side) and L3/L4 (right side). Consequently, the contraction of the pillars may be related to the fixation of the lumbar spine. Proper function of the diaphragm is related to better parameters of static balance. It is also possible to conclude that a change in the proper function of the diaphragm is associated with changes in the center of gravity in healthy individuals. This theme lacks scientific evidence, since no studies were found that focus on the analysis of diaphragmatic treatment only. In this way, the investigators intend to collaborate to increase knowledge in this area, determining the effects of the intervention plan on the diaphragm in relation to the range of motion and center of gravity in the lumbar spine (static and dynamic) in healthy individuals.

Interventions

Type	Name	Description
OTHER	Intervention Protocol in Diaphragm	The protocol consists of three techniques. The two first techniques will be applied for 10 respiratory cycles. Muscle Stretching Technique: the researcher will perform a cephalic traction on the inferior costal border with the ulnar border during the inspiratory phase. Phrenic-center inhibition technique: the researcher, with a hand on the sternum to caudal and other hand on the umbilical region to cranial, will approach his hands on the horizontal plane, when the volunteer exales. Functional diaphragm technique: the researcher will perform a vertical pressure on the diaphragm for 5 minutes and will search for the facilitated parameters and maintain them until the release of all the periarticular elements.
OTHER	Sham technique	In the sham group a manual contact without any therapeutic intention will be performed, in a distant region of the diaphragm (for example on the trapezius muscle). This contact will be maintained during the same amount of time as for the treatment group.
