Study Overview
Brief 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.
Study Design

- Double (Participant, Outcomes Assessor)
Masking Description
The volunteers will be allocated randomly using a website called radom.org, which ensures that neither neither the volunteer nor the assessor will know the final allocation.

Outcomes
Primary Outcomes
Change from Baseline of Center of gravity immediately after the intervention
Time Frame: Immediately after the intervention
To obtain the center of gravity measurements, it will be used the system Qualisys Track Manager. First, it will be placed in the subject spheric markers on the spinous processes of T12, L3 and S2 and both anterior and posterior superior iliac spines. The cameras will be arranged to cover the area to the test, which it will be performed in a hard surface with the help of reflector-markers that will evaluate the movements. The data will be collected twice, with the eyes open and closed. They'll be standing in the platform for 90 seconds each time and the data will be collected at the 30, 60 and 90 seconds. The software is going to be used to convert the data in coordinates in the x, y and z axis, which it will allow to analyse the tridimensional kinematics of the lumbar spine Through the intrinsical board of Qualysis Track Manager it will be evaluated the relation of the center of pressure with the vertical projection of the center of mass through the distance between both.
Secondary Outcomes
- Change from Baseline in Range of Movement of the lumbar spine immediately after the intervention(Immediately after the intervention)
